Control: The Insecticide typically used to control this insect 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 consume all the leaves of the plant simply put period. The quality and yield of the seeds get decreased due to the heavy attack.


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