Preventive control

Natural enemies


Parasitoids are prevented from attacking a rice caseworms because their eggs are laid in the water and their larvae remain in cases floating in the water.



Cultural and management practices

  1. Early planting, wider spacing (30 20 mm), and by splitting the nitrogen application during the rice 3 growth stages can reduce rice caseworm infestation.
  2. Draining the field at regular intervals (one month after transplanting), using older seedlings as transplanting materials, and/or ratooning can also help control caseworm. Caseworm is found only in irrigated and rainfed areas. It is more prevalent during rainy seasons.
