This Crop Protection Guide is to help growers make informed, effective decisions when using biological control products. Biocontrol agents—whether predatory mites, parasitic wasps, nematodes, or beneficial insects—can behave very differently depending on the crop type, growing environment, and pest pressure. A solution that works well in tomatoes may not perform the same way in ornamental plants or leafy greens. That’s why it's essential to understand not only which biocontrol to use, but also the correct application rates, timing, and specific crop considerations. Some products require early preventive introductions, others need repeated applications or crop-specific adjustments like canopy placement or humidity requirements. Our guide brings all this information together in one place, helping you choose the right products, apply them correctly, and achieve the best possible results in your integrated pest management (IPM) program.
