Management And Control

Cultural Control

Cut leaves loaded with eggs can be collected, then dried or burned. Ploughing the soil under the crowns of host plants can kill the pupae.

Chemical Control

Insecticide is applied when young leaves are 3 cm wide. Two or three applications at weekly intervals to protect the young shoots from attack by D. marginatus. Insecticides such as trichlorphon, deltamelthrin and fenvalerate are effective for the control of D. marginatus.
