“Along with the discussion on fall herbicide applications and calibration, the webinar will offer picolinic acid chemistry training,” said Sam Womble, AgriLife Extension agriculture and natural resources agent, Bexar County. “The PAC training covers the application requirements for the use of Invora herbicide for brush and weed management on rangeland sites.” 

He noted applicators must complete picolinic acid chemistry training every two years and the training is required prior to their being allowed to apply Invora herbicide on rangeland.

The program will offer two Texas Department of Agriculture continuing education units – one each in laws and regulations and integrated pest management.
