Sugarcane Aphids Found in Sorghum

Posted on by

Grain sorghum fields in the Mid-Coast vary in maturity from soft/hard dough to pre-bloom. These fields should be scouted weekly for insect pests.

Sugarcane aphids can cause grain yield losses until a few weeks prior to harvest, but the crop is more sensitive to the aphids earlier in the season. As the sorghum grain… Read More →

Follow this link for a brief video demonstrating how to scout sorghum after bloom. LINK My economic threshold for headworms is 1… Read More →

Much of insect and plant activity occurs as a response to three variables. These variables are… Read More →

The Sorghum Hybrid Trial in Calhoun County was harvested on August 1 in Port Lavaca, TX. These tests should be used along with other similar tests from South Texas to help determine the what to plant next year. Below are the results of grain sorghum hybrid trials in Victoria and Refugio Counties.   Other hybrid test results from Texas A&M AgriLife can be found at: http://varietytesting.tamu.edu/.
