In southern counties there is a significant risk for fire blight from Thursday through the weekend for any Pear or Apple orchards with blossoms open. If your orchards are at risk apply antibiotics at the first opportunity. The forecast rain will also be the first significant scab infection for apples. Growers can personalize their risk by visiting the NEWA website. Enter your zip code and follow the links for fire blight and apple scab. You will be prompted to enter phenology information for your location. Using April 6th for 50% McIntosh green tip, the model indicates approximately 40% ascospore maturity on April 20th for South Harrison Township Gloucester County.

Annual Weed Control for Established Blueberries
The program for the control of annual weeds in blueberries should consider the weed free strip under the row and the middles, sod or tilled, separately. The “Weed Control Season” in blueberries starts in late fall. The program implemented in the spring depends on what herbicides were applied the previous fall. If herbicides were applied in late fall, applications may be able to be delayed until later in the spring. Residual herbicides should be applied before bud break in late winter or early spring after the soil is no longer frozen if no late fall treatment was applied. [Read more…]
