Caterpillar pressure varies across southern Florida, according to the South Florida Pest and Disease Hotline. Few loopers and fall armyworms have been reported along the East Coast. Worm pressure has been persistent around Southwest Florida, however. While southern armyworms are most being reported, there are also loopers, melon worms, beet armyworms, fruitworms and fall armyworms. This depends on the crop …
Increasing Infestations: Whiteflies Problematic Around Southwest Florida
Whitefly infestations are increasing around southwest Florida, according to the South Florida Pest and Disease Hotline. Higher numbers of adults and immatures are being observed in older tomato plants. Populations are also reported to be transient in isolated locations, depending on wind direction.

Alabama Extension Offering Peach Insect, Disease Management Chart
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

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 …
