Kerb Use Approved for Dodder Control as Emergency Exemption for 2019 in MA
Cranberry IPM Message
We have finally gotten a break in the weather this week. Cool temperatures on a few nights are helping some color to develop. Looks like the weather may get hot again next week, so continue to be vigilant on monitoring for soil moisture.
If you are still applying pesticides (e.g., 2nd application of Ridomil or Aliette for Phytophthora), be sure to observe all needed PHIs. Ridomil products and Callisto have a 45-day PHI; Aliette has a 3-day PHI. QuinStar and Poast are 60 days, Stinger is 50 days. Select and Intensity products are 30 days.
