Best Time to Kill Weeds Especially Perennials
•Download as PPTX, PDF•
1 like•114 views
Most people apply herbicides or weed killer at the wrong time of year. This is especially true for perennials. Why? First, you are probably most motivated in the springtime when you first get outside. Second, herbicide labels direct you to apply the herbicide when plants are "actively growing." If there's anytime when weeds are "actively growing," it's in the spring! If you do apply a weed killer to a perennial in spring when weeds are growing fast, you will see evidence of harm to the foliage. However, because sugars are pushing from the roots and rhizomes into the leaves, it can be very difficult for the herbicide to translocate to the roots and underground storage components of the plant. Therefore, you will see a "top-kill" of the invasive plant, but the plant likely will re-sprout. This video gives advice on how to avoid such problems.

Cultivation of ferns - the british pteridological society
Ferns generally require shade, humidity, moist soil that is slightly acidic, and protection from strong winds. They grow best with dappled sunlight, moisture-retaining mulch or compost, and a humus-rich soil. Most native British ferns can tolerate frost but delicate species and those from warmer climates require winter protection. Ferns have low nutrient needs and prefer occasional bonemeal fertilizer to richer soils.

This document provides information on growing soft fruits including raspberries, strawberries, redcurrants. It discusses choosing suitable cultivars based on factors like taste, intended use and space. Site selection considers shelter, sunlight, soil pH and frost protection. Details are given on planting, feeding, pruning, pests/diseases and harvesting requirements for specific varieties of each fruit. Raspberry varieties differ in summer vs. autumn fruiting and cultivation involves trellising, pruning fruited canes and retaining new growth. Strawberry varieties range from early to late season and are planted in summer rows. Redcurrants are grown as bushes or cordons and require pruning of leaders and laterals. Pests and diseases of each fruit
Dryopteris arguta
The Coastal Woodfern is a native fern of western North America that grows 2-3 feet tall and wide. It has dark green leaves that are never stiff or sharp, and grows well in partial shade and moist, well-draining soil. It is drought-deciduous and a good choice for landscaping in woodsy areas or containers due to its attractive appearance without being invasive.
Bacterial gummosis
Bacterial canker, also known as gummosis, is caused by the bacterial pathogens Pseudomonas syringae pv. syringae and P. syringae pv. persicae. It affects stone fruits like plum, cherry, apricot, peach and ornamental Prunus species. Symptoms include sunken areas on stems, spurs and leaves developing brown spots that fall out. Management strategies include using resistant rootstocks and cultivars, maintaining tree health, pruning in early summer, and applying copper-based sprays in autumn and spring. Chemical control relies on fixed copper or Bordeaux mixture applications.
Week 17 plant health 2019
Weeds compete with cultivated plants for resources like water, nutrients, and light. They can reduce crop yields and the aesthetic appeal of ornamental plantings. Weeds can also act as hosts for pests and diseases. There are three main types of weeds: ephemeral weeds which have multiple generations per year, annual weeds which complete their lifecycle in one year, and perennial weeds which live for many years. Weed control methods include physical removal, herbicides, and cultural practices. Herbicides can be contact, systemic, residual, or selective depending on their mode of action.

Precision Electronic Dispenser for Application of Herbicide Sprays and Foam
This talk was given at the Innovations in Invasive Species Management Conference in Coeur d'Alene, Idaho, held from December 10-12, 2019.
Abstract: Conventional backpack sprayers and nozzles use technology adapted from agricultural spraying systems. In the context of managing natural areas and invasive plants, however, this can be problematic, especially at sites with desirable native plants. Conventional spray systems are designed to be used with high pressure. High pressure produces greater quantities of tiny spray drops. These tiny spray drops can easily move off-target, carried by the wind and even air currents created by the act of spraying. This presentation discusses new results from ongoing tests of the Precision Electronic Dispenser from Green Shoots®. The Precision Electronic Dispenser uses ultra-low pressure (generally under about 10 psi) to deliver an herbicide mixture either as an aqueous foam or as liquid spray drops. The potential benefits of ultra-low pressure include: lowering herbicide usage; reducing mortality of nearby desirable plants; and minimizing exposure of workers and the broader environment.
Precision Foam and Spray Dispensers from Green Shoots
This Green Shoots Product Guide introduces you to our precision dispenser products. Our dispensers can all dispense foam. Most of our customers use our foam dispensers to apply foam herbicide to kill invasive plants. The foam weed killer can be applied as a foam spray - this allows the rapid application of foam herbicide. It can be applied as a foam herbicide wipe which permits very precise applications of foam weed killer. Our newest dispenser is the Precision Electronic Dispenser. The Precision Electronic can be used to dispense both foams and liquid spray. When set up for liquid spray, it dispenses an ultra-low pressure spray which reduces off-target harm to desirable plants and limits harm to the environment.
Kill Crown Vetch in 3 Steps
This presentation shows how to remove crown vetch. Crown vetch has long stems that allow it to grown and cover desirable plants. The difficulty in controlling it is that spraying weed killer may also kill those desirable plants. This presentation shows how to control crown vetch without harming those desirable, native plants. It uses foam herbicide from Green Shoots, https://www.greenshootsonline.com/ .
How to Kill a Tree without Cutting It Down
This presentation discusses how to kill a tree without cutting it down and using an herbicide. Our other presentation discusses how to do this without herbicide, "How to Kill a Tree without Chemical." In either case, one of the great benefits of a standing dead tree, or snag, is that it provides great habitat for wildlife. The key question you have to ask is whether the location where the tree is going to stand is suitable. It cannot be close to places that people frequent or near your house or vehicles. Inevitably, the tree will fall. The techniques used in this presentation to kill the tree are the injection method where holes are drilled into the tree's vascular system. The other method is the frill method where a hatchet or other tool is used to cut a slit through the outer bark into the live inner bark.
Garden Weed Killer - Kill Weeds - Not Garden Plants
Precision is critical for killing garden weeds. You need to kill just the weed without harming nearby desirable plants. This is important in any garden but especially gardens with perennials, either native or cultivars. This presentation discusses two techniques for precisely controlling garden weeds, herbicide wiping and cut stem. With both of these techniques, foam weed killer from Green Shoots is used. As shown in these slides, highly accurate applications of weed killer can be made using foam weed killer.
Precision Herbicide Spray and Foam
This is an October 2018 Presentation given at the Joint Conference of the North American Invasive Species Management Association and the Upper Midwest Invasive Species Conference.
A key point in this presentation is that invasive plant management in natural areas requires applications of herbicide be very precise (and accurate). Why? A critical reason is this: native plants in natural areas such as prairies can live a very long time. According to Laurenroth et al. (2008), forbs (flowering plants that aren’t woody plants or grasses) can live about 3 to 25 years and grasses can live from 5 to 39 years. If an herbicide application kills one of those valuable perennials, a significant environmental loss occurs.
How to Use Loppers Efficiently - 7 Tips
Loppers are a great tool for cutting branches and stems up to about 1.5 inches in diameter. This video provides 7 tips on ways to increase their efficiency and make your work easier. The seven tips are: First, choose the right lopper for the job. Second, maintain the loppers. This includes cleaning off sap; sharpening, lubricating, and tightening loose hardware. Third, when cutting, insert the branch deep into the jaws. Fourth, when cutting, use gravity to assist your work. For example, when cutting a branch, point the blade downward. If the blade is pointed upward, the weight of the branch will cause it to pinch the blade. Fifth, when cutting, minimize friction. For example, to cut a small tree, don't cut the trunk first. Instead, cut off the branches and leave a tall stump. When cutting the trunk, make sure the blade face is facing upward. This will reduce the pinching of the blade.
Ultra-Low Pressure Herbicide Dispenser Reduces Drift and Increases Target Adh...
Green Shoots, LLC, will introduce a new ultra-low pressure electric sprayer in 2017. The dispenser can dispense both spray and foam. Ultra-low pressure means there's less misting of the spray which translates into less drift, less off-target harm, and fewer fine spray particles that can cause harm to the operator. Moreover, ultra-low pressure means the battery can be smaller and lighter but still operate just as long. If you have questions, contact us at john@greenshootsonline.com.

How to Kill English Ivy Vines: 3 Steps
This document provides a 3-step process for killing invasive English ivy vines:
1. Prepare by identifying the target plant as English ivy and removing climbing vines first.
2. Cut the vines using loppers or saws to sever them from trees and structures.
3. Apply a herbicide like glyphosate or triclopyr to the freshly cut stumps within 5-10 minutes using a foam applicator to ensure absorption. Leave treated stumps for at least 4 months to fully kill the ivy.
Brush Killer: Why Is Foam Herbicide So Effective on Brush?
Why is Green Shoots foam herbicide such an effective brush killer? This presentation explains why. As shown, there are 3 primary reasons Green Shoots Foam Herbicide is so effective: First, foam herbicide is highly precise; second, foam herbicide clings tenaciously to the target plant; and third, foam herbicide dries slowly allowing the herbicide to fully absorb into target weed. We also provide you with examples of different kinds of brush that can be effectively killed with foam herbicide.
How to Kill Japanese Knotweed Using Low Volume Foam Herbicide
This was a presentation at the 2014 Upper Midwest Invasive Species Conference. It discusses the use of a low drift, foam herbicide system, a novel technique for controlling knotweeds and other plants. The system was developed by Green Shoots, LLC, http://www.greenshootsonline.com/newsite/default.aspx.
How to Kill a Tree that Is Invasive or Unwanted: 5 Tips
This presentation describes how to kill an invasive or unwanted tree using herbicide. The presentation covers when you should work on the target weed tree; what technique you should use on that target weed tree (cut stump or hack-and-squirt); and what herbicide you should use;
Tree of Heaven Control using Foam Herbicide
Tree of Heaven is a invasive species that can be difficult to control. Herbicides applied in late summer or fall after the sap has flowed down are most effective for killing the roots. Two recommended techniques are hack-and-squirt and cut stump. For hack-and-squirt, cuts are made into the inner bark and herbicide foam is inserted. For cut stump, the tree is cut down leaving a 2-5 inch stump and herbicide foam is applied to the exposed phloem. Both techniques require leaving the stump undisturbed for 6 weeks to ensure the herbicide kills the roots.
Girdling Trees to Create Snags and Coarse Wood Debris and to Improve Wildlife...
Girdling trees and creating snags (dead, standing trees) is a great way to thin woodlots. We discuss how to do this with and without herbicide. Research indicates snags and coarse woody debris - all forms of dead wood - are vital to wildlife. The techniques for girdling trees include both mechanical girdles where the phloem layer is completely removed with a hatchet or other implement and chemical girdling where an herbicide is applied to the girdle. Some trees such as aspen can be girdled without using herbicides. Some trees such as red pine are tougher to kill and require applying an herbicide into the cuts. Another way to create a snag is to cut off all the branches. This method works for most conifers but won't work for most deciduous trees.
Targeted Weed Killer: Precision Foam Herbicide Delivery System
One of the biggest drawbacks of conventional herbicide application systems is that they cannot target weeds precisely. Green Shoots has introduced a revolutionary new herbicide delivery system that applies herbicides exactly where you want them - with dramatically reduced drift, overspray, or drip. The system can be used with foliar, cut surface, and wiping techniques. This presentation shows before and after photos demonstrating the effectiveness of the system.
Injection of Herbicides into Rhizomes of Knotweeds and Other Invasive Species
This document is a presentation on methods for controlling invasive knotweed species. It discusses current chemical control methods like foliar spraying, stem injection, and cut stem treatments. It notes the disadvantages of these methods, like using large amounts of herbicide and causing off-target damage. The presentation explores ways to improve methods by reducing the quantity of herbicide used and minimizing off-target impacts. It describes experiments with injecting herbicides into knotweed rhizomes and bending stems to expose tissue before treatment. The goal is developing more effective and sustainable control techniques.

We ran trials on this method for a few years as did other organizations and individuals. Ultimately, we did not find its efficacy to outweigh the labor involved. Therefore, Green Shoots decided not to launch the product. We have however had real success with foliar applications using our Green Shoots Foam Herbicide Dispenser. John Lampe gave a presentation on that system at the Upper Midwest Invasive Species Conference: http://www.slideshare.net/johnlampe/how-to-kill-i.
Method for Controlling Buckthorn - Society for Ecological Restoration 2011
This presentation describes a novel way to control woody invasive plant species like buckthorn. It is especially suitable for small woodland owners and managers.
Wed am manage_woody_lampe
The document describes the "Tall Stump Treatment Method" for controlling buckthorn, an invasive species. The method involves three phases - preparation, cutting, and treatment. In the preparation phase, the property is surveyed to identify the worst buckthorn trees. In the cutting phase, the identified trees are cut high, leaving tall stumps. The treatment phase involves using a scraper and herbicide applicator to apply herbicide to the cut stump using the frill method. The advantages of this method are that it is efficient, splits the work into phases that can be separated by months, makes identification and retreatment of stumps easy, reduces fire risk, and exposes more cambium for better treatment outcomes while minimizing soil and herbicide

Immersive Learning That Works: Research Grounding and Paths Forward
We will metaverse into the essence of immersive learning, into its three dimensions and conceptual models. This approach encompasses elements from teaching methodologies to social involvement, through organizational concerns and technologies. Challenging the perception of learning as knowledge transfer, we introduce a 'Uses, Practices & Strategies' model operationalized by the 'Immersive Learning Brain' and ‘Immersion Cube’ frameworks. This approach offers a comprehensive guide through the intricacies of immersive educational experiences and spotlighting research frontiers, along the immersion dimensions of system, narrative, and agency. Our discourse extends to stakeholders beyond the academic sphere, addressing the interests of technologists, instructional designers, and policymakers. We span various contexts, from formal education to organizational transformation to the new horizon of an AI-pervasive society. This keynote aims to unite the iLRN community in a collaborative journey towards a future where immersive learning research and practice coalesce, paving the way for innovative educational research and practice landscapes.
Unlocking the mysteries of reproduction: Exploring fecundity and gonadosomati...
The pygmy halfbeak Dermogenys colletei, is known for its viviparous nature, this presents an intriguing case of relatively low fecundity, raising questions about potential compensatory reproductive strategies employed by this species. Our study delves into the examination of fecundity and the Gonadosomatic Index (GSI) in the Pygmy Halfbeak, D. colletei (Meisner, 2001), an intriguing viviparous fish indigenous to Sarawak, Borneo. We hypothesize that the Pygmy halfbeak, D. colletei, may exhibit unique reproductive adaptations to offset its low fecundity, thus enhancing its survival and fitness. To address this, we conducted a comprehensive study utilizing 28 mature female specimens of D. colletei, carefully measuring fecundity and GSI to shed light on the reproductive adaptations of this species. Our findings reveal that D. colletei indeed exhibits low fecundity, with a mean of 16.76 ± 2.01, and a mean GSI of 12.83 ± 1.27, providing crucial insights into the reproductive mechanisms at play in this species. These results underscore the existence of unique reproductive strategies in D. colletei, enabling its adaptation and persistence in Borneo's diverse aquatic ecosystems, and call for further ecological research to elucidate these mechanisms. This study lends to a better understanding of viviparous fish in Borneo and contributes to the broader field of aquatic ecology, enhancing our knowledge of species adaptations to unique ecological challenges.

Phenomics assisted breeding in crop improvement
As the population is increasing and will reach about 9 billion upto 2050. Also due to climate change, it is difficult to meet the food requirement of such a large population. Facing the challenges presented by resource shortages, climate
change, and increasing global population, crop yield and quality need to be improved in a sustainable way over the coming decades. Genetic improvement by breeding is the best way to increase crop productivity. With the rapid progression of functional
genomics, an increasing number of crop genomes have been sequenced and dozens of genes influencing key agronomic traits have been identified. However, current genome sequence information has not been adequately exploited for understanding
the complex characteristics of multiple gene, owing to a lack of crop phenotypic data. Efficient, automatic, and accurate technologies and platforms that can capture phenotypic data that can
be linked to genomics information for crop improvement at all growth stages have become as important as genotyping. Thus,
high-throughput phenotyping has become the major bottleneck restricting crop breeding. Plant phenomics has been defined as the high-throughput, accurate acquisition and analysis of multi-dimensional phenotypes
during crop growing stages at the organism level, including the cell, tissue, organ, individual plant, plot, and field levels. With the rapid development of novel sensors, imaging technology,
and analysis methods, numerous infrastructure platforms have been developed for phenotyping.

Authoring a personal GPT for your research and practice: How we created the Q...
Thematic analysis in qualitative research is a time-consuming and systematic task, typically done using teams. Team members must ground their activities on common understandings of the major concepts underlying the thematic analysis, and define criteria for its development. However, conceptual misunderstandings, equivocations, and lack of adherence to criteria are challenges to the quality and speed of this process. Given the distributed and uncertain nature of this process, we wondered if the tasks in thematic analysis could be supported by readily available artificial intelligence chatbots. Our early efforts point to potential benefits: not just saving time in the coding process but better adherence to criteria and grounding, by increasing triangulation between humans and artificial intelligence. This tutorial will provide a description and demonstration of the process we followed, as two academic researchers, to develop a custom ChatGPT to assist with qualitative coding in the thematic data analysis process of immersive learning accounts in a survey of the academic literature: QUAL-E Immersive Learning Thematic Analysis Helper. In the hands-on time, participants will try out QUAL-E and develop their ideas for their own qualitative coding ChatGPT. Participants that have the paid ChatGPT Plus subscription can create a draft of their assistants. The organizers will provide course materials and slide deck that participants will be able to utilize to continue development of their custom GPT. The paid subscription to ChatGPT Plus is not required to participate in this workshop, just for trying out personal GPTs during it.

Describing and Interpreting an Immersive Learning Case with the Immersion Cub...
Current descriptions of immersive learning cases are often difficult or impossible to compare. This is due to a myriad of different options on what details to include, which aspects are relevant, and on the descriptive approaches employed. Also, these aspects often combine very specific details with more general guidelines or indicate intents and rationales without clarifying their implementation. In this paper we provide a method to describe immersive learning cases that is structured to enable comparisons, yet flexible enough to allow researchers and practitioners to decide which aspects to include. This method leverages a taxonomy that classifies educational aspects at three levels (uses, practices, and strategies) and then utilizes two frameworks, the Immersive Learning Brain and the Immersion Cube, to enable a structured description and interpretation of immersive learning cases. The method is then demonstrated on a published immersive learning case on training for wind turbine maintenance using virtual reality. Applying the method results in a structured artifact, the Immersive Learning Case Sheet, that tags the case with its proximal uses, practices, and strategies, and refines the free text case description to ensure that matching details are included. This contribution is thus a case description method in support of future comparative research of immersive learning cases. We then discuss how the resulting description and interpretation can be leveraged to change immersion learning cases, by enriching them (considering low-effort changes or additions) or innovating (exploring more challenging avenues of transformation). The method holds significant promise to support better-grounded research in immersive learning.

https://www.etran.rs/2024/en/home-english/The binding of cosmological structures by massless topological defects
Assuming spherical symmetry and weak field, it is shown that if one solves the Poisson equation or the Einstein field
equations sourced by a topological defect, i.e. a singularity of a very specific form, the result is a localized gravitational
field capable of driving flat rotation (i.e. Keplerian circular orbits at a constant speed for all radii) of test masses on a thin
spherical shell without any underlying mass. Moreover, a large-scale structure which exploits this solution by assembling
concentrically a number of such topological defects can establish a flat stellar or galactic rotation curve, and can also deflect
light in the same manner as an equipotential (isothermal) sphere. Thus, the need for dark matter or modified gravity theory is
mitigated, at least in part.

Best Time to Kill Weeds Especially Perennials
- 1. Best Time to Kill Weeds Especially Perennials By: John Lampe Licensed Pesticide Applicator
- 2. Herbicide labels typically recommend you treat the weed when it’s “actively growing.” However, this guidance is not particularly helpful.
- 3. To treat any invasive weed effectively with weed killer, it is important to understand the plant type and how it grows.
- 4. Perennial Biennial Annual The 3 plant types are:
- 5. Perennial Frost sensitive Moderate frost sensitivity Woody species Biennial 1st Year 2nd Year Annual summer winter I break the three plant types into these sub-categories:
- 6. Perennial Frost sensitive Moderate frost sensitivity Woody species Biennial 1st Year 2nd Year Annual summer winter For each sub-categories, your treatment plan will differ:
- 7. Perennial Frost sensitive Moderate frost sensitivity Woody species Perennials are probably the most difficult for non-agricultural management:
- 8. Rule of Thumb for Perennials Treat as late as possible in the season.
- 9. Why? In fall and winter, perennials are directing their sugar reserves to underground storage such as in roots and rhizomes.
- 10. You want the herbicide to travel with the sugars being transported to the roots and rhizomes.
- 12. Japanese knotweed in bloom Crown VetchBindweed Examples of Frost Sensitive Perennials
- 13. • Treat a month before likely frost • follow-up 2-3 weeks later and treat weeds that are still green. Foam herbicide applied to knotweed Frost Sensitive Perennials:
- 15. Canada thistle Example of moderately frost sensitive perennial
- 16. Foam herbicide on Canada thistle • Treat near or after first frost • Repeat about every 3 weeks as long as target plants remain green Moderately Frost Sensitive Perennials:
- 17. You can also treat perennial thistle rosettes in very early spring before bolting Exception for Moderately Frost Sensitive Perennials: Foam herbicide wiped onto Canada thistle rosette
- 19. Examples of Woody Species Buckthorn monocultureTree of heaven Honeysuckle bush in winter
- 20. Foliar spray on buckthorn leaves in autumn Recommendation: Foliar – treat leaves of woody in early autumn while leaves still fully green.
- 21. Recommendation: Cut Stem – treat woody in late fall or even winter. Cut-stump application frill application
- 22. Recommendation: Basal bark – treat woody in late fall or even winter. Basal bark application
- 23. Question: How can woody perennials be treated in winter when they are clearly not “actively growing” and in fact are dormant?
- 24. I have treated numerous woody species with herbicide in the winter with great success.
- 25. Inner bark or phloem (live tissue) Stump Face Target Area for Herbicide The key is to target the live, inner tissue of the woody stem.
- 26. Such as with this application to a live cut stump.
- 27. Biennial 1st Year 2nd Year Biennials are less complicated to manage.
- 28. Examples of biennial rosettes Garlic mustard rosettes Common burdock rosettes
- 29. Recommendation: Make foliar application to biennial rosettes as follows: • First year in spring or fall • Second year in spring Foam herbicide on bull thistle rosette
- 30. Annual summer winter For annuals, treatment recommendations are straightforward:
- 31. Annual summer winter The earliest in spring or summer Recommendation:
- 32. Annual summer winter Anytime plant is green in fall Recommendation:
