Will this product be effective against grasshoppers on my hydrangeas?
I have a flower bed with shrubs, roses and hydrangeas, and the hydrangeas are getting eaten by grasshoppers.
Ferti-Lome Azalea/Evergreen Food Plus with Systemic is not labeled to kill grasshoppers. We would recommend Bifen IT. It is a general insecticide that is labeled for various pests, grasshoppers included. It is safe to broadcast across your lawn, spray on ornamentals and flowers, and trees as well. It is not labeled to be sprayed on edibles. It can be used indoors and outdoors. You will use 1 fl. oz. per gallon of water. Another product that you could use is Cyonara Lawn and Garden Spray. It is attached to the water house and is RTS (ready to spray). It is labeled to be used outdoors only and cover 16000 sq. ft. of the lawn. Cyonara Lawn and Garden Spray can be used on lawns, yards, vegetable gardens, roses, flowers, trees and shrubs. Please let us know if you have any additional questions.
