Michael from Wentzville, Mo writes,
Can this be used on Grape Vines to help with rust and Japanese beetles?
I'm looking for a well rounded product to control a variety of pests and diseases that my grape vines experience
Ultra- Pure Oil Horticultural Insecticide, Miticide and Fungicide is not labeled to be used on grapes. Due to the sensitivity of Grape Vines and using a fungicide and insecticide together, we recommend contacting your local extension office for the proper combination of products to treat both to prevent damage or burning of the grape vines.
