Ampullaria gigas molluscacide

Abstract

The invention discloses an ampullaria gigas molluscacide which comprises the following raw materials by mass: 1-20 parts of diatomaceous earth or kaolin, 10-20 parts of tea bran, 30-40 parts of sec butyl acetate, 7-15 parts of dimethyl sulfoxide, 1-15 parts of castor oil polyoxyethylene ether, 3-20 parts of beta-cyclodextrin, 3-8 parts of calcium dodecylbenzenesulfonate, 1-10 parts of sodium lignosulfonate, 5-15 parts of propylene glycol, 1-10 parts of an antifreeze, 1-10 parts of a thickening agent, 1-10 parts of a disintegrating agent and 40-60 parts of a molluscicidal active substance; and the molluscicidal active substance comprises sodium pentachlorophenate, arecoline, ginkgolic acid, gallic acid, tea saponin, isoquercetin and leonurine. The ampullaria gigas molluscacide is prepared by compounding of plant active substances and chemical drugs, the usage of the chemical drugs is reduced, environmental pollution is reduced, by compounding of the plant active substances, the molluscicidal activity of the molluscicide is enhanced, and by compounding with the harmless concentration of sodium pentachlorophenate, the molluscicidal effect is excellent.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a molluscicide for apple snails. Background technique [0002] The apple snail is native to the Amazon River Basin in South America. It is one of the 100 malignant invasive alien species in the world, and it is also one of the first 16 "blacklists" of invasive alien species invaded by my country's State Environmental Protection Administration. Apple snails are a high-protein commodity and were introduced into farming, but they were discarded by farmers due to over-breeding, poor management, and poor taste. Due to their strong environmental adaptability, the apple snails reproduced in abundance, causing serious damage to agricultural production. destruction. [0003] Molluscicide methods mainly include biological molluscicide, physical molluscicide and drug molluscicide. At present, drug molluscicides are mainly used in the control of apple snails. Drug molluscicides mainly i...

Problems solved by technology

However, the medicinal property of the plant is relatively slow, the content of the active ingredient of the plant drug extract is low, there are many impurities, and the extraction cost is high.

These shortcomings restrict the wide application of plant molluscicides

At this stage, people have gradually shifted from single drug molluscicide research to plant drug molluscicide. For example, patent No. 201510025184.1 discloses a compound molluscicide, which mainly uses emamectin benzoate and tea Powder compounding is used as molluscicide active ingredient to make molluscicide, but its dependence on chemical drugs is still high
