August Cotton Update

Howdy all!

A lot of our cotton is defoliated and I've seen many pickers running. There is still a bit of cotton waiting for defoliation, especially if it was irrigated. The wet spell that we got earlier this week may also delay harvest of what was left in the fields, but for the most part, the season is wrapping up.

Cotton defoliation is recommended at greater than 60% open bolls, or 4 nodes above cracked boll. For more information, here is some links to past research on defoliation:
