Flavonoids from sorghum plants kill fall armyworm pest on corn; may protect crop
Flavonoids produced by sorghum leaves have shown promising results in combating fall armyworm larvae. When sprayed on the leaves of corn, sorghum flavonoids stunt the growth of fall armyworm and often kill the pest, Penn State researchers report in a new study.
