Female thrips are each capable of laying 250 eggs during a two- to three-week period. Adults may produce several generations each year. Other strategies for controlling thrips in cotton include practices deployed as cultural techniques. At-plant insecticides for thrips control provide a consistent yield response. Most soybean thrips develop from egg to adults in 10 to 30 days, depending upon air temperatures. Cotton acreage reached its height in 1926, when North Carolina producers planted right at 2 million acres. Immature thrips are wingless and crème colored. Always read and follow label instructions. Cotton growers can use an in-furrow, at-plant insecticide/nematicide such as Velum® Total, which delivers wide-spectrum, long-lasting control of nematodes and early-season cotton insects, including thrips, aphids and fleahoppers. They may develop high populations in cotton grown near corn and small grains such as wheat. In about five days under warm weather conditions, eggs hatch as larvae and feed on the leaf surface by gnawing cells and sucking sap. ... Thrips (Thrips tabaci) of Cotton. NC State Extension Research Specialist Dr. Dominic Reisig addresses thrips control in cotton as a part of the CHROME Regional Ag Expo. It is similar in appearance to F. schultzei but paler, making it easy to distinguish from F. schultzei but hard to distinguish from T. tabaci.WFT causes similar damage to cotton seedlings and also eats mite eggs. Thrips can stunt growth and reduce yield potential. Thrips damaged cotton. either alone or in combination with a nematicide. Thrips have a generation (egg to adult) turnover of approximately two to three weeks with several generations occur-ring each year. Heavy populations of thrips can migrate from nearby weeds and crops, especially wheat. Refer to university Extension weekly and monthly reports for scouting guidelines and economic thresholds for insecticide treatments in specific cotton geographies. Gennadius) and thrips, (Thrips tabaci Lindeman) are deleterious to the process of cotton growth and development with their ability to build up to serious proportions as a result of rapid and prolific breeding in cotton plant. How To Treat & Control Thrips Organically. Cotton has been important to North Carolina for many years, both in agricultural production and in the textile industry. When corn plants are stressed for water during long stretches of hot, dry weather, the most damage from corn thrips can occur. This is a useful tool for predicting whether a foliar insecticide application is needed for thrips control in cotton. While foliar applications after heavy thrips damage will not usually increase cotton yields, early application once thrips are detected can help avoid a negative impact on yield. Thrip management is a matter of garden maintenance — reducing the places where thrips may breed — and requires removing plant debris while it’s still on the ground and green. The best approach to managing thrips and other cotton insects is preventative control. Under low to moderate pressure, seed treatments labeled for thrips will go a long way to protect young seedlings from chewing (rasping) damage to soybeans. The threat of soybean thrips damage increases during hot, dry weather. On average, 40% of thrips thrive on leaf litter or dead branches. Feeding thrips strike cotton leaves and terminal buds. Adults range in color from black to yellow. Their color varies from … And the plant bug isn't that far behind. Typically producing several generations per year, soybean thrips overwinter as larvae or adults on hosts such as weeds and neighboring crop residue. Unless 75 percent of trifoliate leaves are damaged, treatment is not likely to be economically practical and could possibly lead to spider mite infestations. Thrips in soybeans are not often noticed, yet they are among the most numerous soybean insect pests. Thrips can be found on numerous crop and weed species, many of which are found within cotton production environment. One of the universal components found in each states management of pests in cotton, is to scout which bugs are present. It was excellent. This might be mites or lace bugs. Typically, thrips themselves do little damage, but they create penetration into corn kernels that allows Fusarium spp. In the winter months, they prefer to be on the ground or under plant debris. The critical time for monitoring thrips is from crop emergence through seedling stages. Thrips infestations in cotton vary by location, planting date, and year. Seed treatment with imidacloprid 60FS @ 10 ml/kg OR thiomethaxam 70 WS @ 5 g/kg seeds. Predatory thrips , green lacewings, minute pirate bugs, mites, and certain parasitic wasps help to control plant-feeding thrips. are two of the most economically important insect pest groups impacting cotton production in the USA today, but are not controlled by current transgenic cotton varieties. Cotton plants are most likely to be harmed by thrips from emergence to the third or fourth leaf stage. Thrips often overwinter on wheat and maturing weeds. Foliar application timing for thrips is most effective when cotton is between the expanded cotyledon to first true leaf stage (see photo). So where are thrips now? Not planting cotton near small grains and onions helps alleviate thrips migration into the field. Farmers should check regional guides and management recommendations for the thrips that dominate in their fields. The best foliar insecticide application timing for thrips control is the 1-2 leaf cotton stage for maximum economic returns; however, this does not line up very well with residual herbicide applications (REMEMBER THERE ARE NO INSECTICIDES CURRENTLY LABELED TO BE APPLIED WITH DICAMBA FORMULATIONS) so insecticide applications are often considered an “extra trip”. The best approach to managing thrips and other cotton insects is preventative control. Right now, it is so dry that thrips pressure might not be as much as in previous years. How to control scale & thrips: 1) Predators. Biological control. In general, they are not host specific; however; species such as onion thrips and tobacco thrips feed on plants in specific families. Based in the College of Agriculture and Life Sciences, we reach millions of Chemical efficacy varies by species of thrips being treated. Tobacco thrips are the most common thrips species that infest North Carolina cotton. Spray NSKE @ 5 % OR acetamiprid 20 SP @ 0.2g/l OR fipronil 5 SC @ 1 ml/l; Stem smearing with imidacloprid 17.8 SL @ 1ml:20 ml water and brush the liquid on the growing tip of the plant DAMAGE TO ONIONS. Thrips may be found in cotton plants throughout the growing season, but early-season seedlings are most susceptible during cool, wet weather.
