Labeled Crop Protection Uses
The linked specimen label includes powdery mildew control and control of mites, aphids, and whiteflies on listed vegetables, fruits, nuts, vine crops, agronomic crops, and ornamentals. Additional disease uses and turf directions are crop-specific. Refer to the full label for the applicable crop, target, and restrictions.
Application and Compatibility
Use a preventative spray schedule for disease management. Application concentration, spray volume, timing, and seasonal limits vary by use; follow the label on your product packaging rather than a single general-purpose rate. Check tank-mix compatibility and test a small area for plant sensitivity before widespread application.
Do not apply through an irrigation system unless the required supplemental chemigation labeling is attached. This biopesticide should not be treated as an unrestricted substitute for a hydroponic silicon supplement.
Handling and Organic Production
The linked specimen label states that the product can be used in organic production. Review the organic documentation and confirm acceptance with your certifier before use in a certified program.
Read the full label and safety data sheet before handling. Follow label requirements for protective clothing, chemical-resistant gloves, eye protection when handling concentrate, restricted entry, storage, and disposal. The linked specimen label may not reflect the most recent approved directions in your state; the label on the product packaging governs use.
