Agricultural control is covered by plastic film mulching, which is beneficial to alleviate the damage of snails; rationally close planting, timely ploughing and vines, removing the old leaves and removing weeds; timely cultivating after rain or watering, destroying the habitat and spawning sites of snails; Some winter snails are exposed to the ground and frozen or eaten by natural enemies.
Artificial trapping of leaves, weeds, and vegetables leaves in the field before sunset, placing a pile every 3 to 5 meters, and collecting the haystacks before dawn.
Lime is segregated in the ditch and the ground is sprinkled with a limestone belt about 10 cm wide, with 5 to 7.5 kg of quicklime per acre, so that the snail crossing the limestone belt is killed.
Chemical control (1) Use 0.5 kg of 6% polyacetaldehyde granules per acre, mix fine soil or fine sand 15-20 kg, and spread evenly in the field in the evening. (2) When the snails do not sneak into the soil in the morning, spray with 800-1000 times of copper sulfate or 1% saline, the control effect can reach more than 80%. (3) If the snail is found to be harmful, use 8% tetraacetaldehyde (Tenno) 1000 times liquid leaf spray in time.
