Grasshopper: This prevails insect found in a number of plants. Valanga nigricornis and Locusta migratoria commonly attacks the plant. The pest typically 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.

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

Leaf Caterpillar: This pest can consume all the leaves of the plant in brief duration. The quality and yield of the seeds get minimized due to the heavy attack.
