Embodiment Construction

[0020] The following examples are only used to illustrate the present invention and are not intended to limit the scope of the present invention. In addition, it should be understood that after reading the teachings of the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims of the present application.

[0021] 1. Configuration of 0.3% azadirachtin biopesticide:

[0022] Take by weighing 3kg of azadirachtin, 100kg of natural humic acid, and 897kg of deionized water.

[0023] First, deionized water is nanometerized, then natural humic acid is added, and the stirring device is started to mix thoroughly; then, azadirachtin is added and mixed evenly, and fully ground with a sand mill, that is, 1000kg of biological substances containing 0.3% azadirachtin are processed. Pesticide formulations.

[0024] The natural humic acid extraction pro...

Abstract

The invention discloses a multifunctional azadirachtin biopesticide and a preparation method thereof, and relates to the field of biopesticides. The multifunctional azadirachtin biopesticide is obtained by uniformly mixing nanocrystallized water and humic acid, then mixing azadirachtin and then grinding, wherein during mixing, the humic acid accounts for 3-15%, the azadirachtin accounts for 0.3-3%, and the balance is the nano water. The preparation takes the nano humic acid as a carrier, is completely dissolved in water, has good stability, and is safe to the environment, people, livestock and other beneficial organisms; the biopesticide is simple in formula, low in cost, high in cost performance and suitable for industrial production; besides, water consumption for diluting the pesticide is low, the labor cost is saved, the biopesticide utilization rate is high, the requirements of organic agricultural product production are met, and no pollution and no residue are caused to the environment. The preparation has a good insecticidal effect on aphid pests, lepidoptera pests, coleoptera pests and the like of main crops, tea leaves and fruit trees, and the soil fertility is increased.

Description

technical field [0001] The invention relates to the technical field of biopesticide production, in particular to a method for preparing biopesticides for crops, tea leaves, fruit tree aphid pests, lepidoptera, coleoptera and other pests while increasing soil fertility. Background technique [0002] In the world's agricultural production process, in order to ensure the output of agricultural products, chemical insecticides are the most diverse and convenient measures, including organophosphorus insecticides, carbamate insecticides, nicotine insecticides, etc. Insecticides, etc., have played a pivotal role in the control of agricultural pests. More than 6 million tons of chemical pesticides are sprayed into the natural environment every year in the world. With the large and unreasonable use of chemical pesticides, while protecting the stable and high yield of crops, it will inevitably bring great harm and many negative effects . Chemical pesticides are highly toxic, causing ...
