Problems solved by technology

[0002] When we cultivate crops, in order to be able to kill pests, we have used chemically synthesized insecticides such as pyrethroid pesticides, carbamate pesticides or organic phosphoric acid compounds in the past. Such pesticides not only remain in plants Harmful substances, causing irreparable pollution to the land environment

Embodiment 1

[0019] Example 1: Sapindus sapindus is removed, the pericarp is chopped and ground into a slurry, 20-35 g of it is added to 1 L of water and boiled for 1 hour, then cooled and filtered to prepare the required saponin active agent. The saponin active agent is detected by the ultraviolet, visible, and near-infrared spectrophotometer produced by JASCO Co., Ltd. The maximum absorption spectrum can reach 265.0nm, and its detergency is excellent. The detergency can be changed to emulsifying power . The difference in origin, soil, climate, and harvest season of Sapindus will also cause differences in ingredients and efficacy.

Embodiment 2

[0020] Example 2, take 300g of Sapindus husk, add 6L of water and boil until boiling for 60min, extract the active ingredients, filter and place it to cool below 40°C, first stir at 7000rpm, slowly add 2000g of the product from the People’s Republic of Bangladesh with a purity of 100% neem oil was stirred for 30 minutes, and then stirred at a speed of 12000 rpm for 15 minutes to achieve emulsification. In order to prevent the loss and decomposition of the effective insect repellent components of neem oil, the mixture should be kept below 45°C during the emulsification process. After the emulsification process is completed, the liquid is left to stand until the foam separates, and then the foam layer is removed to obtain the neem oil emulsion. Mix 300ml of natural vegetable and fruit enzyme solution into this neem oil emulsion and stir well to get the stock solution of insecticide I need.

[0021] The stock solution contains 25-35% neem oil by weight, which is more favorable f...

Abstract

The invention discloses a plant antiscolic and a preparation method thereof, which aims at solving the technical problem of realizing environment protection and desinsectization at the same time. Theplant antiscolic can be obtained by the following method: placing 300g of peel without soap nuts into 6L of water to boil for 60 minutes; cooling and filtering the mixture or filtering and cooling themixture; stirring the mixture by a stirrer at a rotating speed of 7,000rpm; adding 2,000g of Nime tree oil in the mixture and stirring the mixture for 30 minutes; and then stirring the mixture for 15minutes at a rotating speed of 12,000 rpm to make the mixture emulsified and obtain the plant antiscolic for Nime tree oil emulsifies plants. Compared with the prior art, the invention adopts plantsto expel insect pest and promote the thriving of the plants; the plant antiscolic is made of 100 percent of pure natural material, namely a plant antiscolic and improved agent which has no pollution and negative effect on the environment, reduces the use of chemical pesticides, not only can save expenses, but also can reduce the labor intensity if helping the plants grow while achieving the effectof expelling pesticides.

Description

technical field [0001] The invention relates to a pesticide and a preparation method thereof, in particular to a pesticide for repelling insects in plants and a preparation method thereof. Background technique [0002] When we cultivate crops, in order to be able to kill pests, we have used chemically synthesized insecticides such as pyrethroid pesticides, carbamate pesticides or organic phosphoric acid compounds in the past. Such pesticides not only remain in plants Harmful substances cause irreparable pollution to the land environment. Contents of the invention [0003] The object of the present invention is to provide a plant anthelmintic and its preparation method, the technical problem to be solved is to protect the environment while repelling insects. [0004] The present invention adopts the following technical scheme: a plant anthelmintic, the plant anthelmintic can be obtained by the following method: put 300g of Sapindus sapindus pericarp into 6L water and boil ...
