Grasshopper: This is common bug found in a number of plants. Valanga nigricornis and Locusta migratoria commonly attacks the plant. The bug frequently assaults the young plant.

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 pest is carbofuran.

Pest of leaf: The typical insects 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 decreased due to the heavy attack.

Control: This can be managed by picking the old larvae around the surface and getting rid of the attacked leaves.
