Abstract

The invention discloses a molluscicide composition containing metaldehyde and emamectin benzoate, and belongs to the field of chemical prevention and treatment. The molluscicide composition comprises the following effective components: the metaldehyde, the emamectin benzoate and an assistant. The molluscicide composition has very good synergistic effects on prevention and treatment of worms of paddy fields, especially ampullaria gigas; the synergistic ratio of indoor bioassay of the molluscicide composition to chilo suppressalis is (10 to 1) to (1 to 80); a field experiment shows that different dosage forms of two medicine compositions have the very good control efficiency on the chilo suppressalis; the control efficiency of the molluscicide composition on the chilo suppressalis after seven days is over 89%; and the control efficiency of the molluscicide composition on the chilo suppressalis after 14 days is over 87%, and is obviously higher than that of a common agent metaldehyde. The molluscicide composition disclosed by the invention has the characteristics of significant synergistic effects, good control efficiency, low amount and the like, is safe to environment and target organisms, is multi-purpose, is capable of treating other insects (such as chilo suppressalis and tryporyza incertulas) on rice, and has a very good effect on delaying the drug resistance of the ampullaria gigas on the metaldehyde.

Description

technical field [0001] The invention belongs to the field of chemical pest control, and in particular relates to a compound molluscicide for preventing and controlling rice snail pests, especially apple snails. Background technique [0002] Apple snail ( Pomacea canaliculata ) is also known as big bottle snail, Jinbao snail, and snow snail in my country. It is an amphibious freshwater shellfish mollusk, and it has 1 to 3 generations in rice fields in my country every year. Due to the wide range of hosts, large food intake, miscellaneous feeding habits, strong stress tolerance, wide adaptability, and fast fecundity, apple snails quickly became flooded in my country. Rice seedlings are the favorite host crops of apple snails, and apple snails soon become malignant aquatic animals that endanger rice, seriously threatening rice production. Apple snails are distributed south of the Yangtze River in my country, and spread northward at a rate of 8 to 10 kilometers per year. In 2...
