|A lot of cotton is ready for defoliation.|
|Warning signs going up before cotton defoliation.|
Defoliation helps the mature bolls open fully and ensures that lint is free from leaves and other trash. On the other hand, immature bolls will stay immature. The treatment causes the leaves to drop and plant to start drying. This helps the harvesting machines pick the cotton cleanly off the plants and lessen the amount of leaves and debris (we call it trash) collected during the harvest.
