Virginia Cotton: Moving Into The Pre-Defoliation Slot

    The corn pickers are beginning to move, and the overall landscape of agriculture is beginning to change as we begin to enter those late August days of the growing season.

    • It will soon be more desirable to miss rain as late rain increases disease pressure in peanuts, adds to hard lock concerns in cotton that has cracking bolls, and keeps the moisture higher in mature corn resulting in delays. It’s just part of the game and overall, the rain pattern has been generally favorable so far.
    • We are at that part of the season where much of the cotton is cutting out and we are starting to see some open bolls along the road edges. Many years, we don’t see too many open bolls until September, but this year has been showing the signs of an early crop all year.
    • Once you see scattered open bolls throughout the field, you should be within about 3 weeks of defoliation in uniform fields.
    • I expect to be walking in fields the week of Labor Day being able to make defoliation recommendations, and if it is dry, we will be spraying during the first half of September. You probably ought to get some Dropp on hand.
    • Of course there was some late May and even early June emergence in fields that we should keep an eye on for late insect infestations.
