Problems solved by technology

In the past ten years, in order to prevent and control this type of molluscs, 4-5 kinds of molluscicides have been developed, such as Mita (metaldehyde), basulide (triphenyltin acetate), kebasnail (spirulina ethanolamine, etc.) Salt), etc., are all chemical molluscicides, which are highly toxic and pollute the environment, especially water.

Embodiment Construction

[0013] Now in conjunction with the embodiments of the present invention and toxicity test, field efficacy test, the present invention will be further described.

[0014] Formula 1: 15% tea saponin, 10% dispersant, 75% filler.

[0015] Formula 2: 20% tea saponin, 10% dispersant, 70% filler.

[0016] Formula 3: tea saponin 25%, dispersant 12%, filler 63%.

[0017] Formula 4: 30% tea saponin, 15% dispersant, 55% filler.

[0018] Test 1. The molluscicidal activity of the above-mentioned botanical molluscicide was determined according to the method specified in the Agricultural Standard NY / T1154.6-2006 of the People's Republic of China.

[0019] 1. Experimental design

[0020] 1.1 Test material preparation

[0021] In 2008, egg masses of apple snails were collected in the Ruian rice field in southern Zhejiang, brought back to the rice plant and placed in a cement tank for hatching, and then reared with duckweed at a temperature of 25-28°C until the young snails grow to the size...

Abstract

The usage of botanical molluscicide and tea saponin belongs to the technical field of agricultural chemical. The molluscicide is characterized by containing 15-30% of tea saponin, 8-15% of dispersant and 55-75% of filling agent, wherein, the dispersant is dodecyl sodium sulfate or nekal, and the filling agent is calcium bicarbonate or white carbon black. The botanical molluscicide takes the tea saponin as a main material so that the botanical molluscicide has low toxicity, quick results and good mollusk killing effect, and can kill pomacea canaliculata, oncomelania, and shell snails and field snails which damage cotton, soy beans and vegetables, and can be made into a wettable powder; and the cost of material is low. The tea saponin can be used for preparing pesticides for killing mollusks, such as pomacea canaliculata, oncomelania, shell snails and field snails.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to the application of plant-based molluscicide and tea saponin. Background technique [0002] Apple snail is a kind of edible snail that was introduced into my country from Southeast Asia in the 1980s. During the feeding and eating process, it escaped and multiplied in large numbers, seriously endangering various plants in water areas. Due to its high fecundity and rapid spread, it is currently in In the area south of 29 degrees north latitude in my country, it has become a big harmful snail for rice and other aquatic plants. In the past ten years, in order to prevent and control this type of molluscs, 4-5 kinds of molluscicides have been developed, such as Mita (metaldehyde), basulide (triphenyltin acetate), kebasnail (spirulina ethanolamine, etc.) Salt), etc., all belong to chemical molluscicides, which are highly toxic and pollute the environment, especially water....
