Director of Agriculture information Dr. Isaiah Okeyo says “the warm weather conditions are a conducive environment for the breeding of the fall armyworms unlike the rainy weather conditions that hamper complete metamorphosis of the destructive pests.’’

Okeyo has however cautioned on the application of chemicals saying “the use of chemicals in the fight to eradicate the destructive fall armyworms is expensive and poses a health risk to persons charged with its administration, ultimately detrimental for the environment owing to their potency.”
