Sugarcane Aphids in Grain Sorghum
Grain Sorghum in Lipscomb County is being infested with Sugarcane Aphids again this year. This is the second time in history that the aphid has reached our area.
Grain Sorghum producers need to be aware of the situation and begin scouting field for this pest. I have scouted fields from south of Darrouzett to the Booker Area. I have found aphids in all areas. Those producers in the Booker Area have the highest populations. One field is getting close to needing sprayed.
Control of the Sugarcane Aphid is possible using either Sivanto 200SL or Transform WG.
The more water you use the better control you will get. A ground rig should use somewhere around 10 gallons per acre. Applying from the air, it is best to use 5 gallons of water per acre.
Chlorpyrifas, Dimethoate and Malathion are also labeled for aphid control but university trials demonstrate that these products are not as effective as Sivanto and Transform.
I will update weekly on the Lipscomb County Extension – Agriculture & Natural Resources Facebook page and on our website at http:lipscomb.agrilife.org
