Best Control Measure
Plough the fallow field in the winter season
Plots that are cultivated early, may suffer more virus ddisease transmitted by leaf hopper
Avoid over dose application of Nitrogen fertilizer
Cultivate late maturing varieties with transplanting machine
Keep the abundance of predators (spider) in the field
Chemical Control
Apply approved systemic insecticides at recommended rate
