Evaluating the application interval of in-season drip and foliar insecticides for vine mealybug management in grapes, 2024
James T Brown and others
Vines treated with the Movento–Movento on 5 September 2024 had significantly fewer nymphs and adult mealybugs on the trunks compared with the untreated control ( z -ratio = 3.01, P -value = 0.014) and—Pridixor–Plenexos Smart-treated vines ( z -ratio = 3.56, P -value = 0.002). Fewer mealybugs were recorded on ...

Evaluation of biological and synthetic insecticides for control of Lepidopteran caterpillar complex in CBD hemp, 2024
G Shrestha and others
The treatments had a significant effect on the total number of injured flower buds (bud rot) at harvest. Coragen, Dipel, and Heligen treatments had significantly fewer bud injuries than the untreated control and Mustang Maxx. None of the treatments showed signs of phytotoxicity. This research was supported USDA IR4 ...

Comparison of drip and foliar-applied insecticides for mealybug management in grapes, 2024
James T Brown and others
Foliar and drip applications of flonicamid (Beleaf 50SC) and flupyradifurone (Sivanto Prime) were compared to determine which application on grape vines would more effectively manage mealybug, Planococcus ficus . This trial was conducted in a 30-year-old “Thompson Seedless cv.” of raisin grapes in Selma CA. The experiment ...

Evaluation of foliar applications of Verdepryn 100SL for control of Diaphorina citri in Florida citrus orchards, 2024
Emilie Demard and Lauren M Diepenbrock
The interaction DAT × treatment was significant for adults and nymphs ( F 9,27 = 20.28, P  < 0.0001; F 9,34 = 11.70, P  < 0.0001, respectively). For both stages, there were no significant differences in psyllid counts among plots before treatments were applied. For psyllid adults, both Verdepryn treatments had ...
