- Store chemicals properly: Keep them out of the reach of children and pets.
Troubleshooting Common Foliar Spray Issues
Even with careful application, foliar sprays can sometimes cause problems. Here are some common issues and how to address them:
- Leaf burn: If leaves appear scorched or discolored, it may be due to over-application or application during peak sunlight hours. Reduce the application rate or apply during cooler parts of the day.
- Nutrient deficiencies: If plants exhibit symptoms like yellowing leaves or stunted growth, it could be a sign of nutrient deficiency. Adjust your foliar spray regimen to provide the necessary nutrients.
