From the Lower Rio Grande Valley to the Texas Upper Coast, grain sorghum harvest is underway at various stages in each region. Leading sorghum harvest are producers in the Valley where the majority of grain has been harvested in the Upper Valley with only late-planted sorghum in Cameron County lagging behind because of dry, hot conditions and a lack of sustainable moisture.

Last week’s heavy rains slowed harvest efforts considerably with some Lower Valley fields left to dry and continue to mature. As a result, producers are watching for disease and pest pressure as significant numbers of problems have begun to surface.

Cotton across deep South Texas is nearing or has reached maturity and harvest will probably begin over the weekend and continue in the weeks ahead. Significant acres of late planted cotton are just now reaching defoliation.

“Many fields had only bolls left in the tops of the plants. Many more fields had open bolls, especially in dryland fields but also in irrigated fields that were either planted by

mid-March or which have not had enough supplemental water to keep up with plant needs,” reported John Norman, AgriLife IPM Extension specialist (ret) and editor of the Valley’s Pest Cast Newsletter.

Norman says hot, dry conditions have dominated the region except for last week’s exceptional rains, but both dryland and irrigated cotton appear to be in good condition. Additional dry conditions, however, could cause rapid yield loss and advance harvest schedules.
