Management and cultural practices

  1. Practice crop rotation. Plant leguminous crops after rice.
  2. When population is high, drain the field to make it dry for a couple of days. This will expose the snails to the sunlight.
  3. Prepare the field evenly.
  4. Avoid direct seeding. Transplant older seedlings. For the early maturing varieties, transplant 25 - 30 day-old seedlings; and for the late-maturing ones, transplant 30 - 35 day-old ones.
  5. Grow more seedlings than that of the recommended rate.
  6. Plant on the ridges above the water line to attract the females to lay their eggs on these rice plants. Collect the eggs and larvae or pull the plant. The eggs, larvae, and adult must be properly crushed, and the pulled-rice plant must be removed from the field.
  7. Raising fish inside the paddy minimizes snails and other rice pests.
