Susie from Billings, Mt writes,

Any treatment for rose bushes when using too strong application per gal. of water?

A lot of the concentrated insecticide stuck to the leaves and they continue to have white spots even after spraying with water.


The mixing ratio for Sevin Concentrate when spraying on ornamentals, including roses, is 1.5 fl. oz. per gallon of water. That is the only rate that it should be used at according to the label.
