Grasshopper: This is typical bug discovered in numerous plants. Valanga nigricornis and Locusta migratoria extensively attacks the plant. The pest often attacks the young plant.

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

Pest observed in fully grown plants:

Pest of Stem: Ostrinia furnacalis, Xyleborus spp.

Control: The Insecticide typically utilized to manage this bug is carbofuran.

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

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