Glyphosate is an herbicide used to control a wide range of undesirable plants in lawns and gardens, row crops, pastures, aquatics, road sides, rights-of-way, and other managed area.

The fall armyworm is a common pest of bermudagrass, sorghum, corn, wheat and ryegrass and many other crops in north and central Texas. Armyworms are very small (1/8 inch) at first, cause little plant damage and as a result infestations often go unnoticed. Larvae feed for 2-3 weeks and full grown larvae are about 1 to 1-1/2 inches long. Given their immense appetite, great numbers, and marching ability, fall armyworms can damage entire fields or pastures in a few days. Fall armyworm outbreaks in pastures and hay fields… Read More →

For the first time in a while, not a single county in Texas is in Extreme or Exceptional Drought conditions (according to the latest US Drought Monitor). All of this extra rainfall has been appreciated but has also been cursed by many crop and hay producers. So what does all this rainfall mean for our forages? Weeds have matured and multiplied due to inability to spray at appropriate times. Once fields are accessible and there is a window of opportunity be prepared to control weeds whether mechanically or… Read More →

Entomologist from Texas A&M AgriLife Extension have just released a publication on the Sugarcane Aphid (SCA). This publication summarizes the latest information on biology, scouting, economic thresholds and insecticides for SCA control in grain and forage sorghum. We are still learning more about this new pest and this publication will be updated as new research becomes available. Website: Texas Sugarcane Aphid News Publication: SCA Management Guide        

Many growers make no distinction at all between perennial and annual sow thistles. That’s because all three versions are tall weeds with yellow, dandelion-like flowers and stems that produce a milky sap. Seedlings of the two species(Sonchus asper & Sonchus oleraceus) are practically indistinguishable, and may be difficult to tell apart even at spray stage without examining the root system. Annual and perennial sow thistle will be covered in an upcoming post. Spiny Sow Thistle (Sonchus asper): An annual that has bluish-green leaves and stems that emit a… Read More →
