A newly registered insecticide, PQZ, from Nichino America has shown good efficacy against the adult stage of silverleaf whitefly in multiple small plot tests in the last few weeks. While overall efficacy has not been fully evaluated, the activity on adults has appeared equal to Sivanto, which has been considered…

We are currently detecting a variety of whitefly-vectored viral diseases in vegetable crops. The two of greatest concern are cucurbit leaf crumple virus and tomato yellow leaf curl virus. Both have been detected in multiple counties in southern Georgia but are generally at low levels to date; unfortunately, this could…

Silverleaf whitefly populations have increased in many areas in the last few weeks and will likely continue to increase as we stay above average temperatures. When we start to cool off at night, the population increases should slow down. We have been fortunate that we have not seen population explosions…

Problems with seedcorn maggots in transplanted crops are popping up all over south Georgia this Spring. While this is a rare occasion (use of transplants avoids many soil borne insect problems), that makes it no less severe when it occurs. Maggots can kill tender young transplants, but cause minimal injury…
