Grasshopper: This is common bug found in numerous plants. Valanga nigricornis and Locusta migratoria commonly assaults the plant. The attacks the young plant.
Control: The insecticides used betacyfluthrin, cypermethrin, thiodicarb, MIPC, and fipronil.
Pest observed in mature plants:
Pest of Stem: Ostrinia furnacalis, Xyleborus spp.

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 in brief duration. The quality and yield of the seeds get reduced due to the heavy attack.
