Oriental Fruit Moth: We are between generations 1 and 2, with the first insecticide applications having been just applied in southern counties, and in northern counties due by the weekend. The second application will be due the following week. [Read more…]

Peach:
Oriental Fruit Moth: We are between generations 1 and 2, with the first insecticide applications due in southern counties in 10 days to 2 weeks. Where trap captures are below 8 moths per trap and no injury is present, then stretch insecticides to get as close to the model timing as possible. Where trap counts continue above 8 males per trap, then the population is too high to take this approach. This is the case in several orchards in northern counties. [Read more…]

Plum Curculio (PC): PC oviposition is coming to an end in most counties. The Cornell model recommends that insecticides are only needed until 308 DD base 50 after apple petal fall. This was June 1 in southern counties and should be about June 5 in Hunterdon County and slightly later north of Pittstown. Therefore applications made this week in southern counties should control this generation of PC. In the southern part of the state we also have the southern strain PC, which has 2 generations per year. Therefore this may be a returning issue in mid-summer.

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…]
