The snails in the vegetable field were in the fall

Snails are the more common pests on vegetables and oilseeds. They use the tongue to scrape the leaves and stems of the host, forming holes or nicks, and even biting the seedlings, resulting in lack of seedlings and ridges. Snails generally cause a lot of activities in April-May and September-October, and the autumn is more harmful than spring. The specific prevention methods are as follows:

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.
