FAQs

How do stem-borers damage rice before it is ripe?

Stem-borers lay eggs on rice. After hatching, the young caterpillars eat the heart of the plant, destroying tillers if the plant has not flowered and affecting the fruit if it has flowered.

What should you consider when using nitrogen fertilizer to reduce stem-borer damage?

Avoid using too much nitrogen fertilizer, because it can soften the rice heart and make it easier for caterpillars to enter and feed.

Why might maggots require replanting, and what is the recommended control approach?

Maggots can severely damage the rice heart and cause plants to die; if many plants are eaten, replanting may be necessary. Treating seeds is presented as the best way to manage maggots, with leaf spraying if treatment is needed again after planting.
