Teasel is an invasive weed introduced from Europe that has spread throughout parts of the Midwest United States. It produces large numbers of seeds and has a deep taproot that allows it to outcompete other plants. Studies examined teasel's growth cycle, seed production, effects of mowing and herbicides, and use of remote sensing to map populations. Results showed that teasel can produce over 30,000 seeds per plant, mowing below 12 cm prevents flowering, and herbicides combined with seeding desirable grasses provided the most effective control strategy. Ongoing management is needed as teasel populations have proven resilient over decades of control efforts.
This document evaluates 11 cucumber cultivars grown within high tunnels. Key findings:
- 'Dasher II' produced the highest yield, followed by 'Indy' and 'Tasty Green'. 'Dasher II' is a slicing type with good powdery mildew tolerance.
- European types like 'Camaro' and 'Milligon' did not perform as well, possibly due to lack of powdery mildew tolerance and needing a longer, warmer season than provided by the unheated high tunnels.
- Trellising significantly improved yields and fruit quality, especially for long-fruited cultivars over 10 inches. Trellising maintained good fruit shape.
This document describes the cell transformation assay (CTA) using BALB/c 3T3 cells. The CTA is an in vitro test used to identify the carcinogenic potential of test substances. It involves exposing cultured BALB/c 3T3 cells to test substances and observing any morphological changes indicative of transformation, such as altered growth patterns and tumorigenicity. The document outlines the experimental design, including culturing conditions, exposure concentrations and durations, and analysis methods to score transformed foci formation and compare results to controls. The goal is to efficiently screen substances for carcinogenicity and further toxicological study.
Japanese knotweed is an invasive plant species native to Asia that was introduced to the United States in the late 1800s as an ornamental plant and for erosion control. It is an herbaceous shrub that grows 3-12 feet tall with red, hollow, jointed stems and oval leaves. It spreads rapidly through rhizomes and fragments and crowds out native species. Control methods include physical removal, herbicides like glyphosate, and biological controls. The document provides details on identification, life cycle, impacts, and control options for Japanese knotweed.
Japanese knotweed was introduced to Europe as an ornamental plant but is now considered an invasive species. It spreads rapidly through an extensive root system and is very difficult to control. Regular cutting or pulling can help manage the plant but disposal of cuttings and roots requires care to avoid further spread. Herbicides such as glyphosate can also be used for control if applied correctly over several seasons. Proper safety precautions and disposal methods are important when dealing with Japanese knotweed.
Japanese knotweed is an invasive plant introduced from Asia to Europe in the 19th century. It spreads rapidly through underground rhizomes and outcompetes native species. It causes significant economic and environmental damage through impacts like damage to infrastructure and reduced biodiversity. Controlling the plant is difficult as even small rhizome fragments can generate new plants, and complete removal of existing infestations is very expensive. Biological control using natural predators from the plant's native range is now being considered as a more sustainable long-term management approach.

Effect of vermicompost on growth and yield of groundnutHeri Cahyono
This document summarizes a study on the effects of vermicompost on the growth and yield of groundnut plants. The study found that applying 200g of vermicompost at 25, 50, 75, and 100 days after sowing led to the highest root length, shoot length, leaf area, number of root nodules, fresh weight, dry weight, and chlorophyll levels in the plants. It also resulted in the highest number of pods per plant (65), number of seeds per pod (116), and hundred seed weight (288.5g). The study suggests that vermicompost can improve the growth and yield of groundnut crops when applied at key growth stages.
This study screened eight varieties of oil radish for their potential as trap crops and biofumigants against root-knot and reniform nematodes. Two experiments were conducted: 1) a greenhouse pot experiment that found 'Sodbuster' and 'Discovery' varieties most reduced nematode populations and increased zucchini growth; 2) a bench experiment that found 'Summer Cross' and 'April Cross' did not support nematode reproduction or root galling, indicating potential as non-host trap crops. The results suggest oil radish, particularly certain varieties, could be effective biofumigants and trap crops for managing root-knot nematodes, though further research is needed on reniform nematodes.

Anti Termite Activity of Jatropha Curcas Linn. Biochemicals ZX7
The study evaluated the anti-termite activity of Jatropha curcas oil and its toxic fraction against Microcerotermes beesoni termites. Wood blocks were treated with different concentrations (1%, 5%, 10%, 20%) of the oil and toxic fraction. Both treatments showed the highest protection at 20% concentration. Weight loss ranged from 18.77-48.80% for the oil and 10.48-35.19% for the toxic fraction. All treatments proved more effective than the control, with minimum weight loss of 10.48% for the toxic fraction at 20% concentration. The oil and toxic fraction demonstrated potential as natural termite control agents.
Non-monetary inputs play an important role in sustainable cropping systems. Some key non-monetary inputs include tillage practices, time of sowing, plant population, choice of crops and varieties, pest management, and weed management. For example, minimum or zero tillage can reduce costs while maintaining yield through improved soil health. Proper timing and plant spacing are also crucial for optimizing yields. Selecting drought-tolerant or pest-resistant varieties suited to local conditions helps maximize productivity with fewer purchased inputs. Integrated pest management and intercropping can also control pests and weeds at low cost. Together, optimizing these non-monetary factors through agroecological practices is important for profitable and sustainable

Garlic mustard is an invasive plant species with white four-petaled flowers and leaves that smell like garlic when crushed. It produces long thin seed pods that can yield hundreds to thousands of seeds. Control techniques for garlic mustard include hand pulling, cutting, burning, and spraying with 2% glyphosate, which is more effective at controlling both young and established plants across large areas. However, spraying risks affecting non-target species. The document provides data that garlic mustard was found on 360 acres out of a 6400 acre park.
Yellow Floating-Heart is an invasive aquatic plant native to eastern Asia and the Mediterranean. It has round to heart-shaped leaves up to 12 cm wide with often purple undersides. Its two to five yellow flowers from May to October have fringed petals above the water surface. It reproduces by seed and fragmentation, preferring slow moving water and damp mud in depths from 0 to 4 meters, where it forms dense mats. Originally cultivated in New England in the 1890s, it was first observed in Washington state in the 1930s and is commonly sold for ornamental ponds, though preventing its spread is important as no biological controls are known and mechanical removal can worsen infestations.
This document summarizes a presentation by Ryan Wersal on alligatorweed, an invasive aquatic plant species. It discusses alligatorweed's origins in South America and impacts as a nuisance species worldwide. The presentation describes alligatorweed's identification features, habitat, distribution in the US, ecological impacts including reduced water quality and access, and management methods such as biological control using beetles or moths and chemical control with herbicides. Contact information is provided for Ryan Wersal as an expert on alligatorweed management.
Sericea lespedeza is a perennial legume native to eastern Asia that was introduced to the US in the late 1800s as a potential forage species and for erosion control. It has since become a problematic invasive weed in many states. It grows 2-4 feet tall with hairy stems and leaves and produces abundant purple flowers and yellow-red seeds. While it can fix nitrogen and tolerate drought and flooding, its high tannin levels make it unpalatable to cattle. Chemical herbicides, especially triclopyr and fluroxypyr, are most effective at controlling it if applied before flowering, though multiple annual treatments are typically needed for eradication due to its large seed bank.
This document discusses the control of reed canary grass, an invasive perennial grass, at Ted Shanks CA. It provides background on the plant's life history and describes how it became established at the site in the 1970s. Control efforts from 2004-2007 are outlined, including burning residual growth, disking to break up the sod layer multiple times, planting a winter wheat cover crop, and using herbicides. The lessons learned emphasize the need for repeated treatments to exhaust the plant's rhizomes and revegetating quickly. An integrated approach is recommended using the strengths of various control methods tailored to site characteristics.
The document discusses curly leaf pondweed, an invasive aquatic plant native to Eurasia. It describes its physical characteristics and life cycle, noting it grows actively in winter and reproduces through turions, seeds, and fragmentation.

Effective management includes prevention, physical removal, and chemical control in early spring using herbicides such as endothol, fluridone, and diquat.
The document discusses kudzu control strategies in Missouri and Illinois. It outlines both states' laws designating kudzu as a noxious weed. Missouri law requires controlling the spread of kudzu using herbicides according to label instructions. The document also discusses integrated control strategies used in both states, including foliar herbicide application, vine origin treatments, and potential use of bioherbicides.
Japanese honeysuckle is a woody vine native to Japan and Korea that was introduced to North America in the early 1800s as an ornamental plant. It grows in woodlands, prairies, and edges, and has opposite leaves and very fragrant white to yellow flowers from April to July. It spreads quickly by seeds dispersed by animals and by rooting at nodes, and can girdle and outcompete native trees and shrubs. Control methods include foliar glyphosate applications in fall, cutting and painting stems with glyphosate, and prescribed burns to limit its spread.
Japanese stiltgrass is an invasive annual grass native to Asia that has spread throughout the eastern US. It grows in a variety of habitats and can dominate forest understories, reducing diversity and restricting tree growth. While it pulls up easily, stiltgrass is difficult to eradicate due to long-lived seeds and spread through water, animals, and human activities like equipment. Effective management requires controlling it before seed production using herbicides, mowing, or burning, along with preventing further spread through equipment sanitation and regional coordination of control efforts.
The document discusses Japanese chaff flower (Achyranthes japonica), an invasive plant species first found in the Ohio River Valley in the 1980s. It has since spread widely throughout the region. The plant can grow over 5 feet tall and forms dense stands that spread rapidly via water, animals, and humans. It is impacting riparian habitats and may displace other species. Early detection and prevention of spread is important. Control methods include herbicide application in summer before flowering. More research is still needed on management of this invasive plant.
Euonymus fortunei (wintercreeper euonymus) is an invasive woody vine introduced from East Asia as an ornamental ground cover. It spreads vigorously by stems along the ground and climbing vertical surfaces, outcompeting native plants. Its dense growth can kill trees and shrubs. Effective control methods include repeated foliar spraying with glyphosate in fall, cutting stems and applying glyphosate to cuts, digging out roots, prescribed burns, and replacing with alternative native ground covers or vines.
This document discusses efficient control methods for bush honeysuckle, an invasive plant species. It provides details on the plant's biology and introduction to North America. Control priorities and costs are outlined, with contracted work ranging from $150-400/acre for foliar treatment to $3200/acre for cut and chip removal. Hands-on control methods like cutting, digging, and pulling are also described. Maintaining controlled areas is emphasized to prevent reestablishment of invasives through seeding desirable species or regular burning/mowing. Photos show the before and after impacts of control work.
This document discusses the invasive algae Didymosphenia geminata, also known as rock snot. It forms thick mats that negatively impact streams by decreasing clarity, oxygen, and suitable habitat for other organisms. It currently exists in 22 US states, including nearby Arkansas. The algae thrives in conditions with high nitrogen, low phosphorus, sunlight, and stable water flow. Efforts to control it include developing predictive models, adding phosphorus, using copper compounds, cleaning equipment, and increasing public awareness through educational materials.
Japanese hop (Humulus japonicus) was originally imported to the United States in the late 1800s for use in Asian medicine and as an ornamental vine. It has become an invasive species that can form dense mats, blocking sunlight and killing other vegetation. The document describes Japanese hop's habitat requirements, how it reproduces and spreads rapidly, identification features, and various control methods including manual, biological, cultural, and chemical approaches. It also provides a case study of how Japanese hop overtook a riparian forest planting on a Missouri farm after a flood.
This document discusses the non-native common reed (Phragmites australis), including its invasive characteristics and methods for control and management. The non-native common reed forms dense monocultures that degrade wildlife habitat and increase fire risk. It has competitive advantages over native plants through elevated levels of allelopathic biochemicals. Effective control methods include applying herbicides like imazapyr and glyphosate in late summer or fall. Follow-up treatments may use fire or additional herbicides to prevent regrowth. Long-term monitoring is needed to manage the invasive populations over time.
The Brittle Naiad is a non-native annual plant that was first discovered in the U.S. in the 1930s, reproduces by seed and fragmentation, tolerates moderate turbidity and fertile water, and outcompetes native plants by reducing diversity and choking water bodies which can impede use and affect aesthetics. Control options include grass carp and aquatic herbicides such as Diquat, Endothall, Fluridone, and Flumioxazin.

37. What do we know now?
Plants emerge during 2 distinct periods in Missouri
Teasel has two important peaks of above ground growth
Teasel stores resources in the taproot to catapault plants into
reproduction
Seed production is greatest when plants invade new areas;
seeds reach viability quickly following initial flowering
Mowing below 12 cm precludes plant flowering; plants remain
alive and flower the following year
Herbicides can reduce the number of existing plants
and imazapyr reduces the emergence
Remote sensing can identify teasel; combination of herbicides
and seeding desirable grasses is most effective strategy
38. Chester McWhorter (USDA weed scientist)
“I have spent the last 16 years of my career
working on johnsongrass, and I can report that
johnsongrass is a bigger problem today than
when I began.”
-1991
I have worked on teasel for about 8 years and cannot
say populations are in decline!
