Camptothecin plant molluscacide and preparation and application method thereof

Abstract

The invention provides a camptothecin plant molluscacide and a preparation and application method thereof. The crystalline powder of the camptothecin is prepared into 0.05-0.1g / L of molluscacide aqueoThe invention provides a camptothecin plant molluscacide and a preparation and application method thereof. The crystalline powder of the camptothecin is prepared into 0.05-0.1g / L of molluscacide aqueous solution and molluscacide pelletized granule with camptothecin content of 0.25-0.30 percent. The camptothecin plant molluscacide is pure chemical component and meets the requirement of environmentaus solution and molluscacide pelletized granule with camptothecin content of 0.25-0.30 percent. The camptothecin plant molluscacide is pure chemical component and meets the requirement of environmental protection, and the oncomelania control effect of the Camptothecin plant molluscacide can be evaluate in a standardized way; and the invention has good effect of expelling and killing the oncomelanil protection, and the oncomelania control effect of the Camptothecin plant molluscacide can be evaluate in a standardized way; and the invention has good effect of expelling and killing the oncomelania and also has the advantages of simple manufacturing process, lower cost, convenient storage and transportation, no pollution to the environment, no harm to human, animals and fish and obvious economa and also has the advantages of simple manufacturing process, lower cost, convenient storage and transportation, no pollution to the environment, no harm to human, animals and fish and obvious economic benefit, social benefit and ecological benefit.ic benefit, social benefit and ecological benefit.

Description

technical field [0001] The invention relates to a camptothecin plant molluscicide for killing snails and a preparation and application method thereof. Background technique [0002] Schistosomiasis is a disease that seriously endangers human health. Oncomelania is an indispensable link in the transmission of schistosomiasis, and mollusc control can effectively reduce the transmission of schistosomiasis. At present, there are roughly three mollusc control methods: artificial mollusc control, chemical drug mollusc control and biological mollusc control. Manual mollusc control is labor-intensive, time-consuming and expensive, and chemical drugs are expensive, have a short validity period, are poisonous to humans, livestock, and fish, and are likely to cause environmental pollution. [0003] In order to avoid the pollution of the environment by chemical drug molluscicides, people always want to obtain pure natural plant molluscicides. Plant molluscicides such as rhizome powder...
