High Plains sorghum outlook outlined by AgriLife Extension specialists

by Kay Ledbetter, Texas A&M AgriLife

Producers may be concerned about planting sorghum this season, but several Texas A&M AgriLife Extension Service specialists said there are ways to prepare for upcoming issues and be profitable.

During the Interstate 40 Sorghum Luncheon recently in Amarillo, producers heard the latest on managing sugarcane aphids, weed control and how it all figures into the bottom line as producers manage crop budgets and pricing strategies. Continue reading

Bacterial blight on resistant cotton varieties

See Southwest Farm Press for photos and data tables

The moderate temperatures and wet conditions experienced throughout the High Plains from May to July were conducive for the development of bacterial blight (Fig. 1). An increase in the disease was observed across most of the region with observations of bacterial blight-like symptoms occurring on varieties that had previously been documented as being resistant or immune.

Initial ratings of a research trial near Plains, Texas, found the disease to be present in most all plots with disease incidence averaging nearly 25 percent. Upon closer examination, the ratings were found to be incorrect resulting from erroneous labeling of plots in the field. This is good news from a production perspective, as the updated disease ratings with correctly labeled plots immune.

Scout for bacterial blight in High Plains Texas

In Southwest Farm Press

by Jason Woodward and Terry Wheeler, Texas A&M AgriLife

Bacterial blight, caused by Xanthomonas axonopodis pv.malvacearum, has been reported from most all cotton production regions around the world. The bacterium is capable of surviving saprophytically on infested crop residue. Dry arid conditions facilitate survival in soil from year to year.

Cotton plants are susceptible to infection at all growth stages; however, leaves and bolls are most commonly infected later in the growing season. Conditions that favor disease development consist of moderate temperatures and high humidity. Wounding of leaves by blowing sand or hail may lead to an increase in incidence of the disease. Sprinkler irrigation can increase spread of the pathogen.
