Fruit IPM For 6/4/19

Peach:

Plum Curculio (PC): PC oviposition should be done in all areas of the state, and there is up to 2-3% of fruit injury with egg scars. We have accumulated about 911 DD since petal fall (apple) in southern counties and just over 663 DD in Hunterdon County. The Cornell model calls for insecticides applied up to the 340 DD50 mark. Therefore, all sprays for this insect should be done. The model assumes a single generation in NJ, which is historically what we have had. New research from Anne Nielsen’s lab is telling us that the southern strain of PC is also present in the state. This is a multi-voltine strain, which means there is more than one generation per year in some parts of the state. Therefore with an early spring, we may see additional injury later in the season.
