IPM Message for Cranberry Growers: Jul 27, 2009

Jul 27, 2009

Spraganothis fruitworm larvae have been found in fruit, so you should be aware of this. If you have not taken care of your weevil infestations, it is getting to be too late for Actara. Prophlatic sprays for cranberry fruitworm should no longer be going out. You shoul only be making insecticide applications when the number of unhatched, viable eggs exceeds the action threshold. Admire can still go out for soil insects.

I have had no reports of QuinStar working on dodder. The Section 18 expires on July 31, this Friday. You must still fill out a form for MDAR if you used QuinStar, even if it did not work. Poast and Callisto can be combined but this combination cannot be chemigated. You must apply it by ground equipment since Poast cannot be chemigated. Some folks have reported that combining Poast and Callisto has been hurting dodder, but I have not seen this myself. If you have noticed any injury with this combination, please let me know at ext. 21.Callisto has a 45-day PHI.
