Oriental Fruit Moth: Second generation timings are updated below. Second flight adults started this past week in southern counties and are about to start this coming week in northern counties. According to the model, treatments for the second generation should be going on  now in  southern counties, and should start next week in northern counties. [Read more…]

Recent Rain Patterns and Insecticide Use:

Given our recent periods of rainy weather, many growers are questioning the need for repeated applications, and the weatherability of the materials already applied. Dr. John Wise at MSU has been studying the residual properties of insecticides for a number of years. [Read more…]

Peach:

Plum Curculio (PC): PC oviposition continues in all areas of the state. We have seen increasing levels of damage, particularly in northern counties with up to 2-3% of fruit injury with egg scars. We have accumulated about 103 DD since petal fall (apple) in southern counties and just over 64 DD in Hunterdon County. The Cornell model calls for insecticides applied up to the 340 DD₅₀ mark. This allows for the last of the PC activity to be covered by the residual from the last insecticide application. Therefore PC is still a primary target and needs to be controlled during the next couple of applications. [Read more…]

Peach:

Plum Curculio (PC): PC adults are still active and will damage fruit if not controlled. Fresh injury is being found in several plantings, particularly in northern orchards. PC is a key pest to control during the first few weeks after petal fall. [Read more…]
