Grain sorghum that was planted prior to these recent rains has average stands at V2 and V3 growth stage. There is still much grain sorghum acreage to be planted. The sugarcane aphid is currently present in all 3 counties as we have found it on haygrazer, Johnsongrass mainly, with some being seen on volunteer grain sorghum. For the most part it has been very hard finding volunteer grain sorghum this year… which is good. However it has been easier finding the sugarcane aphid present on other hosts. Our conclusion from these observations is sugarcane aphids are more thoroughly established this year in their winter populations. Current products that are effective at controlling the sugarcane aphid and are available for use are sulfloxafor (Transform) and flupyradifurone (Sivanto). Sulfloxafor received approval for use in Texas (Section 18) and has an updated label for this year that you can find at https://texasagriculture.gov. Flupyradifurone is also effective and has received approval for reduced rate use. Please contact your local chemical dealer for further information on these products.
