Multifunctional nano humic acid-based azadirachtin biopesticide and preparation method thereof

Abstract

The invention discloses a multifunctional nano humic acid-based azadirachtin biopesticide and a preparation method thereof, and relates to the field of biopesticides; the multifunctional nano humic acid-based azadirachtin biopesticide is obtained by uniformly mixing nano water and humic acid, then mixing with azadirachtin, and then grinding; during mixing, humic acid accounts for 3-15%, azadirachtin accounts for 0.3-3%, and the balance is nano water. The preparation takes 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; the agent dilution water consumption islow, 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, coleopteran pests and the like of main crops, tea leaves and fruit trees, and the soil fertility is improved.

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 ...
