Planting sorghums early might help reduce sugarcane aphid damages

by Kay Ledbetter, Texas A&M AgriLife

Every year is a learning year right now for Texas A&M AgriLife Extension Service entomologists and anyone else dealing with the sugarcane aphid, both on grain sorghum and forage sorghum in the Texas High Plains.

“We have a lot more information about grain sorghum than we do on the forage sorghum,” said Dr. Ed Bynum, AgriLife Extension entomologist at Amarillo. Continue reading

Beekeepers and farmers in Mississippi work together to protect each other’s interests

Cooperation between Mississippi beekeepers and farmers has been an important factor in obtaining Section 18 approval for sulfloxaflor (Transform), a key pesticide for cotton and grain sorghum.

The EPA approval was “really good news,” says Angus Catchot, coming on the heels of a California Ninth Circuit Court decision last year that resulted in the EPA cancelling sufloxaflor registrations in all crops as a result of allegations by the Pollinator Stewardship Council and other non-governmental organizations that there was not sufficient research on its potential impact on pollinators to support registration of the compound.

Sugarcane aphid is already devastating Texas grain sorghum

by Rod Santa Ana, Texas AgriLife

It may be hard to spot, but the tiny sugarcane aphid is racking up tens of millions of dollars in losses in just the four South Texas counties evaluated so far, according to a report by an economist with the Texas A&M AgriLife Extension Service.

And the losses would have been much higher had grain sorghum growers not followed the advice of AgriLife Extension experts, according to Dr. Samuel Zapata, who conducted the study from the Texas A&M AgriLife Research and Extension Center in Weslaco. Continue reading

Sorghum growers need a solid management plan

In Delta Farm Press

If you’re going to grow grain sorghum this year, you should factor into your plans a solid insect management plan, says Angus Catchot, Mississippi State University Extension professor of entomology and plant pathology.

“Going into the season, have a plan to deal with a few of the most common yield robbers: sugarcane aphid, sorghum midge, and the headworm complex,” he said at the annual meeting of the Mississippi Agricultural Consultants Association. Continue reading

Mississippi sorghum growers were ready for sugarcane aphids

In Delta Farm Press

After causing significant challenges in 2014, sugarcane aphids did not catch Mississippi’s grain sorghum growers by surprise this year.

“We are not sure if sugarcane aphids were not as bad as last year or if we just did a better job using insecticidal seed treatments,” said Angus Catchot, an entomologist with the Mississippi State University Extension Service. “One big difference was that we were more educated in our control efforts. No one was caught by surprise, and everyone had budgeted for control.”

LSU tests sorghum hybrids to fight sugarcane aphid

In Delta Farm Press

Entomologists believe some grain sorghum varieties are more tolerant of sugarcane aphids than others. But they’re not sure which ones are a fit for being designated as resistant or tolerant and which ones aren’t.

That’s why researchers at the LSU AgCenter are conducting trials with grain sorghum varieties that are believed to be resistant at the Northeast Research Station at St. Joseph and other locations, according to David Kerns, who is based at the Macon Ridge Research Station in Winnsboro, La
