Prevathon® insect control powered by Rynaxypyr® active provides effective control of corn earworm, sorghum webworm and fall armyworm that feed on sorghum heads. Prevathon insect control brings the powerful active ingredient Rynaxypyr to the sorghum industry and, along with it, effective, long-lasting insect control; a shorter re- entry interval (four hours) after application; and minimal impact to most beneficial insect species, thereby not flaring aphids or mites. Prevathon insect control combines these attributes to optimize sorghum yields and quality while having an excellent worker protection standard profile.

What are Sorghum Headworms?

Sorghum headworms are made up of three different species of caterpillars, cotton earworm, sorghum webworm and fall armyworm. Sorghum headworms feed on the flowers and developing kernels, which can cause severe yield loss if left uncontrolled. Scouting for sorghum headworms should begin immediately after the majority of the sorghum heads in a field have finished flowering. Typical thresholds are one to two larvae per sorghum head and may vary with the size and species of the headworm and the value of the crop.
