Improved management of Lygus bugs has reduced unnecessary insecticide applications reducing risk to crops and the environment
Alfalfa strips provide habitat for natural enemies and mitigate Lygus bug movement
What Has ANR Done?A UCCE advisor designed several projects to evaluate the source and sink relationships of crops surrounding susceptible fields to Lygus pest management. UCCE facilitated local participatory meetings to help inform growers and Pest Control Advisors (PCAs) of the situation. Educational outreach provided principles to situate crops in patterns which reduce the threat of Lygus movement between crops within this mixed cropping landscape as well as manage pests within crop sources to prevent movement into susceptible crops.
Growers are now using best managment practicesBy applying the knowledge gained from these participatory group meetings, local research and individual consultations, this community developed and adopted good management practices to mitigate Lygus bug movement, e.g. by focusing on the neighboring sources of the pest reduced the need for treating the primary focus crop because the pest never migrated. Twenty growers and PCAs now employ best management IPM practices to control Lygus bugs, within the constraints of crop rotations for soil health and ground water protection. The understanding of landscape level management has substantially improved the situation in managing Lygus bugs, reducing unnecessary insecticide applications and reduced risk to the cotton crop and environment.
