Can other products be added to DiPel such as Harpin Protein? How often should DiPel be applied to vegetable and flower gardens? Should DiPel be applied to leaves, stems & surrounding soil. Is a light spray sufficient?
Per the product label, you could potentially mix DiPel PRO DF Biological Insecticide with other products; however, you would need to do a small tank mix for compatibility first. You also need to use the most restrictive labeling of any products that you are mixing.
Applications can be repeated at 3-14 day intervals depending on the target pest and conditions such as plant growth rate and rainfall. Thorough coverage is needed for sufficient control since the target pests must consume the deposits of DiPel to be affected. Please refer to the product label for complete application instructions.
