Problems solved by technology

Most pesticides are unstable and easy to degrade under natural conditions, resulting in short duration of pesticides and low utilization rate; moreover, the surface of most crop leaves has hydrophobic micro-nano structures such as waxy layers, hairs, papillae, and pesticide droplets It is difficult to attach to crop leaves and fall off into the natural environment, further reducing the utilization rate of pesticides. At the same time, pesticides falling off into the natural environment will cause environmental pollution, which will not only threaten human health, but also induce pesticide resistance of harmful organisms

Embodiment 2

[0039] The method of Example 1 was used to prepare the pesticide nano-loading system. The difference from Example 1 was that the active ingredients included 1 part by weight of natural pyrethrin and 10 parts by weight of azadirachtin.

Embodiment 3

[0041] Using the method of Example 1 to prepare the pesticide nano-loading system, the difference from Example 1 is that the active ingredients include 1 part by weight of natural pyrethrin and 0.5 part by weight of azadirachtin.

Abstract

The present disclosure relates to a pesticide nano-drug delivery system for controlling pine cone pests. The pesticide nano-drug delivery system comprises nanoparticles and an active ingredient encapsulated in the nanoparticles; wherein the nanoparticles are composed of a carrier material and auxiliary components, and the effective components comprise 1 part by weight of natural pyrethrin and 0.1to 40 parts by weight of azadirachtin. Through the technical scheme, the pesticide nano-drug delivery system provided by the invention has an obvious sustained and controlled release effect, and can prolong the lasting period of the drug; meanwhile, the pesticide nano-drug delivery system further has high leaf affinity, can be well attached to crop leaves, and prevents a large number of pesticideliquid drops from entering the natural environment to pollute the natural environment, so that the pesticide nano-drug delivery system disclosed by the invention reduces the dosage and improves the pesticide effect; The pesticide nano-drug delivery system also has obvious effects in relieving environmental pollution, pest drug resistance, biodiversity loss and the like caused by abuse of pesticides.

Description

technical field [0001] The present disclosure relates to the technical field of pesticide production, in particular to a pesticide nano-carrying system for controlling pine cone pests and a preparation method thereof. Background technique [0002] Pesticides are an important resource for agricultural production. The application of pesticides is an important means to prevent and control crop diseases and insect pests and regulate crop growth. It is of great significance for agricultural production to maintain and increase production. Most pesticides are unstable and easy to degrade under natural conditions, resulting in short duration of pesticides and low utilization rate; moreover, the surface of most crop leaves has hydrophobic micro-nano structures such as waxy layers, hairs, papillae, and pesticide droplets It is difficult to attach to crop leaves and fall off into the natural environment, further reducing the utilization rate of pesticides. At the same time, pesticides ...
