Tree Fruit Fire Blight Alert: Extreme
The Cougar Blight model at NEWA is predicting “Extreme Risk” for fire blight for the period May 10-15. The model is basing the prediction on the current weather forecast for both southern and northern regions. Keep a close eye on the weather. Apply antibiotics such as Streptomycin, Mycoshield, or Fireline. Streptomycin is the most effective of the antibiotics. The Terramycin products (Mycoshield and Fireline) should be rotated with strep for resistance management. See the New Jersey Commercial Tree Fruit Production Guide for rates. Keep in mind that these antibiotics are best applied under slow drying conditions (dilute applications), and have limited residual activity.

Tree Fruit Fire Blight Alert: Caution
The Cougar Blight model at NEWA is predicting “Caution” for all Apple and Pear blocks with open blossoms starting May 7. The model is basing the prediction on the current weather forecast for both southern and northern regions. Keep a close eye on the weather. If conditions for infection occur (60°F or above with rain or severe weather including high winds) apply antibiotics such as Streptomycin, Mycoshield, or Fireline. Streptomycin is the most effective of the antibiotics. The Terramycin products (Mycoshield and Fireline) should be rotated with strep for resistance management. See the New Jersey Commercial Tree Fruit Production Guide for rates. Keep in mind that these antibiotics are best applied under slow drying conditions (dilute applications), and have limited residual activity.

Early Season Grape IPMThe season has gotten off to a slow start due to cool weather across the region but once it warms up you can expect the shoots to grow very quickly.
Blueberry Diseases
- Blueberry Scorch Disease
- Phomopsis Twig Blight
- Blueberry Shock Virus
- Anthracnose
Blueberry bloom is progressing nicely and bee activity seems reasonably good. Our biggest enemies are wind and cold. Botrytis does not seem to be developing in blueberry fields and should not pose any risk in the next 7-days. Anthracnose is our biggest disease concern at this point. Hopefully all conventional growers will have made one application of Ziram and will be looking at an application of Abound next week.
