Biopesticide for killing oncomelania

Abstract

The invention discloses a biopesticide for killing oncomelania, which comprises the following materials in parts by weight: 35-64 parts of nicotine, 11-19 parts of celastrus angulatus, 10-16 parts of paraquat, 3-7 parts of sapium sebiferum, 15-20 parts of kushenin, 11-14 parts of santonin water aqua, 3-6 parts of fructus amomi, 10-12 parts of juglone, 25-36 parts of broad beans, 45-50 parts of ethanol, 5-11 parts of hirsutella thompsonii fisher powder and 35-40 parts of sanguinarine. The biopesticide disclosed by the invention has a good killing effect, and is quite obvious in function of killing oncomelania under a low concentration; and the biopesticide is low in toxicity to human, animals, aquatic plants and other aquatic animals, and is capable of relieving pollution to soil and water quality. The biopesticide disclosed by the invention is simple in formula, and easy and simple in preparation method.

Description

technical field [0001] The invention relates to a biological pesticide for killing snails. Background technique [0002] Due to the inherent shortcomings of chemical pesticides and the long-term unreasonable abuse of people, serious 3R problems have been caused, namely: resistance, resurgence and residue, and also destroyed the ecology of nature. balance. Therefore, people turn their research goals to extract insecticidal active ingredients from plants and develop botanical insecticides. Because biopesticides are derived from natural products, they are easy to degrade, have a short residual effect period, and pests are not easy to develop resistance, so they have broad market prospects. In recent years, the use and development of biopesticides has been led by Japan, Europe and the United States to the world, and has become an international research hotspot, especially the biopesticides prepared by using the phytotoxins secreted by plants to protect themselves from diseases...

Problems solved by technology

The molluscicide sodium pentachlorophenate, which has been widely used in the past, is extremely toxic, pollutes the environment, and has serious public hazards. It has a strong inhibitory effect on the microbial activity and dominant flora in the environmental soil, especially the cumulative toxicity to the human body. disabled
