Since the product label for DiPel Pro DF Insecticide does not state that it is safe for aquaponics or for use around aquatic areas, we would not recommend this type of application. You may want to reach out to Valent, the manufacturer, directly: you can reach them on their website here.
Per the product label: DiPel PRO DF Biological Insecticide may be tank mixed with other labeled insecticides to enhance control. Use of the resulting tank mix must be in accordance with the more restrictive label limitations and precautions. No dosage rates should be exceeded. This product cannot be mixed with any product containing a label prohibition against such mixing. Before tank mixing DiPel PRO DF with other labeled products, including spreader stickers, check for tank mix compatibility
No, Dipel Pro is not a liquid product and would not be suitable for most hose end sprayers. There are a few hose end sprayers that can accept granules or dry flowables but they are no very accurate. Instead we recommend you use a pressurized sprayer or a product such as the Chapin Slide Pump Sprayer to spray the branches that are higher up.
DiPel Pro DF will not control june bugs or other beetles or weevils. Essentria All Purpose is a natural insecticide spray which you can use for these and other insects on your fruit trees.
