The Q&A Archives: worms on my grapes

Question: i have 2 new grape plants that were doing well until i noticed the leaves scaling, underneath were rows of short fat stripped worms! what kind of organic insecticide can i use?

Answer: I'm not exactly sure what's feasting on your grape leaves but an organic control is Bt (bacillus thuringensis) sold as Dipel or Thuricide. Bt targets only caterpillars and does not harm people, pets, wildlife or beneficial insects. Good luck with your grapes.
