Artificial control: before the snail overwinters or lays eggs, the adult snails and snail eggs in ditches, rivers and farmland should be picked up and removed, and then destroyed centrally. During the incubation period of snail eggs, attention should be paid to drainage and proper field drying to reduce the survival rate of young snails. Biological control: In the areas where Ampullaria canaliculata appears, ducks can be raised to eat Ampullaria canaliculata, and small and medium-sized immunized ducklings with a duck age of 30 days can be selected, and about 20-25 ducks can be raised per mu.

First, how to kill snails?

1, artificial control

(1) Before the snail overwintering or spawning peak, organize personnel to collect and clear adult snails and snail eggs in ditches and farmland and destroy them centrally, or break snail shells and feed them to poultry.

(2) In areas with serious snail damage, irrigation with water must be avoided, and at the same time, interception nets should be set at the entrance of rice fields to prevent the migration of canaliculata canadensis. During the full incubation period of snail eggs, attention should be paid to drainage and proper field drying to reduce the survival rate of young snails.

(3) You can also insert some pieces of wood and bamboo into the rice field to lure snails to lay eggs, so as to concentrate on removing and killing eggs.

2. Biological control

(1) In areas where Ampullaria canaliculata appears, ducks can be fed on Ampullaria canaliculata, and ducks can be put into farmland and ditches to peck at young snails during the full incubation period of snail eggs, thus killing Ampullaria canaliculata and feeding the ducks.

(2) Choose 30-day-old small and medium-sized immunized ducklings and stock about 20-25 ducklings per mu.

3. Chemical control

(1) If there are 2-3 snails per square meter at the site, measures should be taken in time. After ploughing, apply tea seed bran10-20kg per mu, and then carry out seedling throwing and transplanting.

(2) Within 24 hours after transplanting, 0.5 kg of 6% Mida granules, 50 g of 70% shellfish poisoning powder and 200 g of 65% sodium pentachlorophenol powder were mixed with soil and evenly sprinkled on the field.

(3) Pay attention to that the water depth in the field should be about 5cm when applying pesticide, and don't use any highly toxic pesticides such as carbofuran and methyl isofenphos, so as to avoid poisoning. Ducks can't go into the field until half a month after applying pesticide.

Second, the life habits of Ampullaria canaliculata

1, Ampullaria canaliculata has a wide range of feeding habits and belongs to omnivorous snails that feed on plant food. They mainly eat vegetables, fruits and aquatic plants. I especially like to eat foods containing sugar and carrion.

2. Pomacea canaliculata is an aquatic mollusk, which can hide in mud for 6-8 months in dry season.

3. Pomacea canaliculata likes to live in fresh water with clean water quality and sufficient bait, and often lives in shallow water near the pool or is adsorbed on the stems and leaves of aquatic plants.
