Bonide Captain Jack's Organic Fungicide Insecticide Miticide - Liquid Concentrate - 16 fl oz

Sprayed tomato plants that had aphids showing up. Next day, no aphids. Also sprayed peonies with powdery mildew. It helped quite a bit, but some parts of the peonies were already too far gone for it to kill the mildew completely. Next year, I'll use it earlier in the season as a preventative, since the mildew spores can survive in the soil year after year.

I use this on my viburnum shrubs, which are susceptible to caterpillars in the spring. It works well to keep them away. The concentrate is very economical to use. I spray the soil and the branches before they leaf out. Note: I spray in the late afternoon/evening. I find customer service people very helpful and knowledgeable when I call with questions too!
