Grasshoppers are sporadic pests that sometimes migrate in large populations and defoliate gardens. More than 200 grasshopper species occur in California, but only a few like the devastating grasshopper and valley grasshopper cause significant problems. Grasshoppers lay eggs in soil in fall which hatch the following spring. Nymphs molt several times before becoming adults. Population sizes vary yearly, with major outbreaks occurring every 8-10 years if conditions are favorable for several years. Grasshoppers prefer young plants and remove large sections of leaves, sometimes devouring entire plants. Management options during major invasions are limited, but trap crops and insecticides around garden borders can help control smaller populations.

3) Opponents argue GM crops pose enormous risks like creating super-weeds or reducing biodiversity and harming ecosystems. Within 10-20 years the long term risks and impacts may become clearer, but for now individuals
Combating wilt susceptibility in Chickpea – A Success story and Challenges ah...ICARDA
This document discusses the success and ongoing challenges of combating fusarium wilt susceptibility in chickpeas. It summarizes efforts over recent decades to identify sources of wilt resistance through screening landraces and developing resistant varieties. Major accomplishments include the development of varieties JG 315 and JG 74 in the 1980s and subsequent varieties in later decades. However, challenges remain such as new pathotypes of Fusarium oxysporum emerging and increasing issues with other soil-borne diseases under changing climatic conditions. Ongoing efforts are needed to incorporate multiple disease resistance and continue identifying new races of the pathogen.
GMO's and the environment. Currently, GE crops in California include cotton and corn. Potential environmental concerns with GMOs include the escape of transgenes from cultivated crops to wild relatives or other cultivated crops. This could occur through pollen or seed dispersal and affect both target and non-target organisms. While current impacts may be limited, long-term effects require further study. Overall, a case-by-case evaluation is needed considering the environment, organism, and transgene in question.
Thrips are serious pests of many crops that feed on plant tissues, reducing yields. Their populations can be monitored using sticky cards and magnifying lenses. Cultural controls include crop rotation, vegetation management, mulches, and fertilizer use. Some cabbage and onion varieties have genetic resistance. Beneficial insects also suppress thrips naturally. When thresholds are exceeded, organic pesticides are available to control thrips.

The document also notes nematodes have a wide host range and discusses some of their soil and climate preferences that influence their populations.
GURT (Genetic use restriction technology)siddarudh
This document provides an overview of genetic use restriction technology (GURT), also known as "terminator technology". It defines GURT as genetically modifying plants to produce sterile seeds, preventing farmers from reusing seeds. The technology uses three genes - a repressor gene, recombinase gene, and toxin gene - that work together to terminate seeds unless an activator is used. While not yet commercialized, it is being developed by biotech companies to restrict seed reuse and protect intellectual property. However, critics argue it would negatively impact farmers' rights, food security, biodiversity, and local seed varieties that many small farmers depend on for replanting. The document examines both perspectives on this controversial technology.
Genetically Modified Crop is a crop whose genetic characteristics have been altered by the insertion of a gene or a gene from another organism using the techniques of genetic engineering.

Garden symphylans are small, white soil-dwelling arthropods that can cause significant damage to crops. They feed on plant roots, reducing the crop's ability to take up water and nutrients, which leads to stunting or death. Garden symphylans are commonly found in western Oregon, Washington, and California, especially in heavier, well-structured soils with good tilth. Their patchy distribution within fields makes them difficult to sample for and manage. Various sampling methods can be used to determine if they are present in damaging numbers to inform management decisions. Tactics to control damage include those that decrease garden symphylan populations as well as those that reduce their access to crop roots.

How to Make a Field Mandatory in Odoo 17Celine George
In Odoo, making a field required can be done through both Python code and XML views. When you set the required attribute to True in Python code, it makes the field required across all views where it's used. Conversely, when you set the required attribute in XML views, it makes the field required only in the context of that particular view.
2. Cultural and Physical Controls
A combination of several strategies can help keep CPB populations under control. Crop rotation
can delay CPB population buildup, but will not prevent an infestation unless fields are fairly well
isolated. The effects of crop rotation and field proximity on populations of CPB and incidence of early
blight (Alternaria solani) were quantified in a study done in the early 1990s (3). The researchers noted
that the infestations of both these pests were inversely related to the distances between rotated fields
and the nearest locations where potatoes were planted the previous season. In other words, the
farther this season’s potato field is from last season’s potato field, the fewer the pest problems.
Research at Cornell University demonstrated the efficacy of flame technology in controlling over-
wintering CPBs. The most effective time for flaming is between plant emergence and 8 inches in
height. Taller plants are less heat-tolerant and the canopy shields many of the pests. Best control is
achieved on warm, sunny days when beetles are actively feeding on top of the plants. In trials,
flaming resulted in 90% control of overwintering adult CPB, whereas chemical insecticides pro-
vided only 25–50% control. Flaming also reduced egg hatch by 30% (4).
For more information on propane flame weeding, including specifications and sources
of flame weeders, see the ATTRA publications Flame Weeding for Agronomic Crops
and Flame Weeding for Vegetable Crops.
CPB can be excluded from crops with the use of “floating row covers,” a thin fabric spun from
a synthetic material. The product allows air and moisture to travel through it, while preventing
pest species access to the plants. For more information on row covers, see the ATTRA publication
Season Extension Techniques for Market Gardeners.
Another exclusion strategy is the use of plastic-lined trenches as a barrier to CPBs entering a
potato field (5). Beetles can walk on clean plastic mulch at an angle, but once the plastic is coated
with fine soil particles, this becomes impossible. Trenches with walls sloping at greater than 46°
will retain an average of 84% of all adults caught under field conditions. A potato field surrounded
by plastic-lined trenches might see its population of overwintered adult beetles reduced by nearly
half. Small numbers of beetles escape from the trenches during periods of rain, but once the plastic
dries, footing again becomes impossible for the insects. Further details on this strategy are pre-
sented in the 16-minute video from Cornell Cooperative Extension, mentioned above.
In a similar vein, Canadian researchers have developed a portable field-edge trap to keep CPBs
from entering potato or tomato fields after overwintering (6). The first prototype was constructed
from sheet metal, and a subsequent version was made of extruded plastic. The design, which re-
ceived a U.S. patent, makes it easy for beetles to crawl up the sides, where they eventually fall into
the trap. Dozens of CPBs per linear foot were trapped during field tests.
According to another study, mulching with wheat or rye straw may reduce the CPB’s ability to
locate potato fields, and the mulch creates a microenvironment that favors CPB predators (7). In
the first half of the season, soil predators—mostly ground beetles—climb potato plants to feed on
second- and third-instar larvae of the CPB. In the second half of the season, ladybird beetles and
green lacewings are the predominant predators, feeding on eggs and on first and second instars.
Mulched plots supported greater numbers of predators compared to non-mulched plots, resulting
in significantly less defoliation by CPB. Tuber yields were increased by a third.
A mechanical strategy that stimulated considerable interest in the late 1980s and early ‘90s was
the bug vacuum. These were rather large, tractor-drawn machines that sucked insects from the
crop plants and killed them, usually by shattering them against the fan housing. One particular
unit—the beetle eater—was intended for use on CPB in potatoes. Interest in insect vacuums was
not long-lived. Problems were noted with soil compaction, loss of beneficial insects, and lack of
efficacy on heavier pests deep within crop canopies (8). A few machines, however, remain in com-

Protection.
Varietal Resistance
Several genetically-engineered potato varieties are available to commercial growers, but these
are not permitted in certified organic production. A few traditional potato varieties (e.g., ‘Russet
Burbank’) seem to be more tolerant of CPB than others, but none of them can be considered “resis-
tant.”
The April 1989 issue of National Gardening highlighted research on planting early-maturing
varieties that develop potato tubers before CPB populations explode (10). It lists seven varieties that
mature in 75 to 88 days—Caribe, Norland, Pungo, Redsen, Sunrise, Superior, and Yukon Gold—
and illustrates the growth stage of the potatoes versus CPB emergence and larval development.
This practice may prove especially beneficial to growers in northern regions, where cooler tempera-
tures slow insect development.
Biological Control
CPB has several natural enemies, but they are rarely seen in commercial potato fields because of
heavy pesticide use and lack of habitat to support them. Even under organic growing conditions,
where natural enemies are more abundant, they will probably not completely control the CPB. The
generalist predators—ladybird beetles, lacewings, predatory stink bugs, spiders, etc.—provide some
control. There are also a number of CPB parasites. Doryphorophaga doryphorae and D. coberrans
are two species of fly that parasitize CPB larvae; a wasp, Edovum puttleri, parasitizes eggs.
Increasing habitat for natural enemies by providing pollen and nectar sources along field bor-
ders or by planting insectary strips in the field can increase the effectiveness of these biological
controls. ATTRA has more information on this technique in the Farmscaping to Enhance Biological
Control publication. As mentioned above under “Cultural and Physical Controls,” mulching also
favors CPB predators.
Botanicals
A few commercial botanical preparations are available for use on CPB. Rotenone is derived from
the roots of a South American plant. Since it is somewhat slow at killing pests, it is often combined
with pyrethrum for a faster “knockdown.” Plant protection is relatively brief, usually lasting two
days or less. Rotenone must be used with caution as it is quite toxic to fish and swine. Rotenone is a
restricted material, one that should be used only when other, less severe options fail to exert adequate
control. Be certain to read the label directions for specific instructions and cautions.
Various products with the active ingredient azadirachtin (from neem tree seeds) have some
efficacy against CPB in the early crop stages. These include Neemix™, BioNeem™, and Margosan-
O™. However, spray concentrations of 1% and greater may cause phytotoxicity on potato plants
(11). Furthermore, though they were once considered benign to beneficial insects, neem products
have demonstrated some negative impacts. Washington State research has found neem to be toxic
to ladybeetles, especially in their early larval stages (12). Meanwhile, research in Maine found
neem less effective than Bacillus thuringiensis (see “Biopesticides” on page 4) (13).
Pyola™ is a natural insecticide product that combines canola oil with pyrethrins. It is recom-
mended for use on cucumber beetles, flea beetles, Mexican bean beetles, squash bugs, aphids, mites,
and CPB (14). However, since much of the canola oil on the market is derived from genetically
engineered plants, this product may or may not be acceptable for organic production. Growers
should contact their certifying agent before purchase and use.
//COLORADO POTATO BEETLE: ORGANIC CONTROL OPTIONS PAGE 3
4. A number of herbs and herbal extracts are also reputed to repel or inhibit CPB, though research
has been far from thorough. Among the plants believed to have some effect are: catnip, tansy, sage
(15), hemp (16), oak extract (17), wild potato (Solanum chacoense) (18), and citrus oils (19).
Biopesticides
Several biopesticide products based on the bacterium Bacillus thuringiensis (Bt) have become avail-
able in recent years. M-One™, made from B. thuringiensis ssp. san diego, is genetically engineered and
therefore is not allowed in certified organic production. Novodor™, produced by Valent USA Corp.
(20), contains B. thuringiensis ssp. tenebrionis, a form of Bt that is not genetically engineered and can be
used by organic producers in most states. One source of Novodor is Peaceful Valley Farm Supply
(21).
Bt is effective only if ingested by the pest, and then only in the larval stage. Furthermore, Bt
sprays are generally effective only against newly hatched CPB larvae. Applications should be made
within one to two days whenever one or both of two criteria are met:
• densities of egg masses reach or exceed 4 per 50 vines and at least 25% of the oldest masses have
hatched or are hatching;
• densities of small larvae reach the treatment threshold of 76 per 50 plants or stems (22).
Bt is most effective if applied when daytime temperatures reach or exceed 75°F, because larval
feeding is then increased (22).
Another biopesticide, Mycotrol™, is based on the fungal agent Beauveria bassiana. Like Bt, B.
bassiana is a naturally occurring organism. Unlike Bt, B. bassiana is effective against all larval and
adult stages of CPB. Furthermore, once B. bassiana is applied, it can continue to propagate and
provide a significant level of CPB control throughout the remainder of the season. The most signifi-
cant limitation of B. bassiana appears to be its sensitivity to high temperatures. Mycotrol works best
between 70 and 80°F. Growth of the organism is much slower at warmer temperatures (23). As a
result, this may be a poor option for growers in southern states during much of the growing season.
Emerald BioAgriculture Corp. (24), the manufacturer of Mycotrol™, recommends spraying
when hatching occurs in 20–25% of the egg masses—timing similar to that for Bt. A possible
strategy involves combining Bt with B. bassiana for optimum efficacy. While Bt is effective at killing
early-instar larvae, it will also slow the growth of larger larvae and make them more susceptible to
the fungus (23).
Parasitic nematodes are another control option. Commercial formulations of Heterorhabditis
species are available and have been shown to be more pathogenic (25) to the CPB than Steinernema
species of nematodes, which are also commercially available.
