Chemical Compatibility Tables Updated

Jul 13, 2025

We’ve updated the Pesticide Compatibility tables under the Learn menu on the Natural Enemies website. These are handy tools to help you navigate the compatibility of our products with other substances that might be present in the growing environment. In order for the biologicals to protect the plants it’s important to protect the biologicals!

Natural Enemies-Chemical Compatibility addresses the effects of various chemicals on the beneficials. These are substances found in a typical growing environment in fertilizers, growth moderators, or other common products. You can locate the Koppert product in the left hand column and the chemicals across the top. Find the cell where the product and chemical meet and BINGO!—you’ll have your answer.

Beneficial Insect & Pesticide Compatibility performs a similar function regarding the active ingredient in some of the most common pesticides for home growers. Look in the right hand column to find the compatibility measured in mortality rate of commonly used beneficial insects. We hope these tools help—that’s what we’re here to do. If you have any questions when navigating the tables, remember there’s a real person ready to help you on the other end of our live chat.
