Control: The insecticides utilized betacyfluthrin, cypermethrin, thiodicarb, MIPC, and fipronil.

Pest observed in fully grown plants:

Pest of Stem: Ostrinia furnacalis, Xyleborus spp.

Control: The Insecticide generally used to control this insect is carbofuran.

Pest of leaf: The typical bugs observed are leaf caterpillar, Neetle caterpillar, Leaf hopper, Mite, Ear corn caterpillar.

Leaf Caterpillar: This insect can eat all the leaves of the plant simply put duration. The quality and yield of the seeds get lowered due to the heavy attack.

Control: This can be managed by choosing the old larvae around the surface and tossing away the attacked leaves.
