Imidacloprid 75 wsb
 

I have looked high and low. What is the gallon per powder mix ratio? Thanks and why do they not put in on the label? Frustrating.

I wish I could help but didn't realize it came in a powder form.

Call the company and ask for directions on using it for roses. They probably won't have a recommendation for orchids.

I am certain that they do give mixing ratios on the label for some uses. The mixing ratio will, of course, vary according to intended use.

Here is the label for Imidacloprid 75 WSB from one manufacturer and, as you can see, they do provide mixing ratios and instructions.

If roses or tomatoes are on the label, use these recommendations. ;)
