Alabama Extension is offering a Peach Insect and Disease Management Chart for peach producers. The tool is a resource growers can carry with them and help manage insects during certain tree cycles. It includes the most common insect pests, including scale, European red mite, lesser peachtree borer and thrips. It also includes what management options growers have for prevention of …
Insecticide Rotation Key in Long-Term Management of Whiteflies
By Clint Thompson Insecticide rotation when managing whiteflies remains key to long-term success in the Southeast. It has to be if growers want to avoid insecticide resistance developing. Stormy Sparks, University of Georgia (UGA) Cooperative Extension vegetable entomologist, believes farmers have improved in recent years in protecting their insecticides for the future. “The same chemistries that we rely on, primarily …
EU Ban of Pesticides Could Impact U.S. Growers
By Frank Giles Mike Aerts, Florida Fruit & Vegetable Association’s vice president of science and regulatory affairs, recently shared an update from the European Union (EU) that could impact maximum residue limits (MRLs) allowed in the 27-member-country body. MRLs govern the amount of allowable pesticide residue on a food product in order to enter a country. Because the EU has …
Mite-y Big Problem in South Florida
According to the South Florida Pest and Disease Hotline, few spider mite hotspots remain around Homestead, Florida. Broad mites continue to stay active in the area as well. A similar scenario is being reported in the southwest part of the state, too. Spider mites are showing up in various locations on cucurbits, tomatoes and eggplants. Broad mites have flared up …
Chemistry Rotation Needed to Protect Peaches Against Plum Curculio
By Clint Thompson Southeast peach producers have a handle on plum curculio management. Brett Blaauw, assistant professor at the University of Georgia (UGA) College of Agricultural and Environmental Sciences, wants to keep it that way. That’s why the UGA specialist continues to encourage rotation of chemistries to prevent insecticide resistance from occurring. Pyrethroids are growers’ best option for management. But …
UF Research: Environmentally Friendly Way to Control Pest in Strawberries
BALM, Fla. — University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researchers have discovered a more environmentally-friendly way to control the chilli thrips in strawberries. It includes using less pesticides. With a new, biological control method, farmers could save up to 5,000 gallons a year in pesticides that would be used on the crop, said Sriyanka Lahiri, a …
ADAMA’s Cormoran® Effective Against Larval Stages of Insect Pests
By Clint Thompson One insecticide from ADAMA could be a secret weapon for Southeast producers hoping to reduce pest pressure in various specialty crops. Cormoran® attacks the larval stages of insect pests, which makes it a vital part of a grower’s insecticidal rotation, says Jorge Menocal, territory sales representative for ADAMA. “When you refer to specialty vegetables, it’s critical to …
ABT Population Update in South Florida
The University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) reports that higher Asian bean thrips (ABT) populations were reported across South Florida. However, these were observed only in more mature plantings with few blooms. Insecticide applications are not recommended unless scouting indicates populations are greater than 1.0 ABT per bud or bloom. Populations reached 0.6 per bloom in …
Looming Deadline: EPA Ban of Chlorpyrifos Will Impact Peach Production
By Clint Thompson The looming deadline for revocation of tolerances for the use of chlorpyrifos (lorsban) means peach tree producers have a little more than two months to find alternatives in managing two pests. According to Brett Blaauw, assistant professor at the University of Georgia (UGA) College of Agricultural and Environmental Sciences, the ban of chlorpyrifos will impact growers differently …
Low to High: Whitefly Populations Vary in South Florida
Whitefly populations remain a problem in some vegetable crops in the Manatee Ruskin area, according to the South Florida Pest and Disease Hotline. Growers and scouts report that whitefly adult and immature numbers are high in tomatoes and squash. They have also reached moderate levels in cucumber and eggplant. Whitefly pressure is also increasing around the southwest Florida area. The …
