Spraying for pests

[Ernest]

Once I realized that the little marks on many of my blooms were probably "scratches" I ordered some Spinosad. I got the 32 oz hose-end bottle since all of my plants are in the ground and that seemed to be the best way to apply it. I have now sprayed twice (five days apart) using the same bottle. The instructions on the bottle are not very helpful. I initially thought that the level would go down as the Spinosad was used up. But the bottle remains full so it is apparent that the water is constantly diluting the active ingredient.

How does one know when the Spinosad is gone and one is just spraying water on the plants? I also use the hose end bottle for Bayer 3-in-1 and have the same question ablout that.

Erny, that's a good question. I'll look into it and see what I can find out.
