Plum Curculio (PC): PC oviposition continues in all areas of the state. We have accumulated about 253 DD since petal fall (apple) in southern counties. The Cornell model calls for insecticides applied up to the 340 DD50 mark. The current prediction is for southern counties to hit 340 on or about 5/30. This allows for the last of the PC activity to be covered by the residual from the last insecticide application. Therefore applications made this week in southern counties should control this generation of PC. In northern counties PC is still a primary target and needs to be controlled during the next couple of applications. [Read more…]
