Description
Technical Field
The invention relates to the field of agriculture, in particular to a high-efficiency pest control suspending agent and a using method thereof.
Background
Insect pests refer to the damage of harmful insects to the growth of plants, and the kinds of animals harmful to plants are various, wherein the insects mainly comprise mites, snails, mice and the like. In order to avoid the adverse effect of insect pests on agriculture, forestry, animal husbandry and the like, most of diseases are usually eliminated by spraying pesticides. Insecticide (Insecticide) refers to an agent that kills pests, such as beetles, flies, grubs, noseworms, flea bugs and nearly ten thousand other pests. The use of the insecticide goes through several stages in sequence: natural pesticides and inorganic compounds were first discovered, but they were single acting, large in dose, and short in duration; organic synthetic insecticides, such as organochlorines, organophosphates and carbamates, are characterized by high efficacy and low residue, with many species having high acute toxicity to mammals. The action mechanism of a few traditional medicaments, such as mineral oil emulsion and the like, mainly plays a physical insecticidal role on the body surface, and most of organic synthetic insecticides enter the body of pests to interfere or destroy normal physiological and biochemical reactions at certain positions. The pesticide entering the body of the pest enters the digestive tract through the mouth and permeates into the blood, or enters the body of the pest through the epidermis or through the pores and the trachea, the pesticide entering the body and various enzyme systems in the body of the pest carry out biochemical reactions, some reactions lead the pesticide to degrade and lose toxicity, but some pesticides are activated to enhance the toxicity, and the pesticide which is not degraded (or the activated compound) plays a poisoning role in a certain part due to different action mechanisms, such as acting on a nervous system or acting on the respiratory metabolic process in cells.
The lufenuron is a novel substituted carbamide pesticide, kills pests by acting on insect larvae and preventing a desquamation process, has excellent control effect on fruit trees and other leaf-eating caterpillars, has unique killing mechanism on thrips, rust mites and trialeurodes vaporariorum, and is suitable for controlling pests generating resistance to synthetic pyrethrin and organophosphorus pesticide. The duration of the medicament is long, and the medicament is beneficial to reducing the medicament injection times; is safe to crops, can be used for crops such as corn, vegetables, citrus, cotton, potato, grape, soybean and the like, and is suitable for comprehensive pest control. Chinese patent CN201410385091.5 discloses an insecticidal composition containing cyhalodiamide and lufenuron, which can effectively control agricultural pests and effectively delay the development of pest resistance by compounding cyhalodiamide and lufenuron to generate a synergistic effect.

Based on the above, the preparation of a suspending agent which is highly effective in preventing insect damage, has strong stability and low decomposition rate is an urgent problem to be solved in the field.

Performance test method
The insecticidal long-acting property:
the suspending agents prepared in examples 1 to 4 were mixed with water in a weight ratio of 1: 16000 mixing to get mixed solution, spraying on citrus fruit tree until the mixed solution wets the leaves and does not drip, and spraying the whole plant of fruit tree carefully and uniformly to make the front and back of fruit and leaves receive the mixed solution. The initial survival number m1 of Citrus reticulata Russell Puccinia and the survival number m2 of Citrus reticulata Russell Puccinia after 28 days were measured, and the insecticidal ratio K ═ m (m1-m2)/m1X 100%. The suspensions prepared in examples 1 to 4 had insecticidal efficiencies K of 92.3%, 90.1%, 90.7%, and 89.2%, respectively.
Temperature resistance:
the suspending agents prepared in examples 1-10 were stored at 60 ℃ for 18 days with reference to GB/T19136-.
Decomposition rate:
the lufenuron concentration change of the suspension agents prepared in examples 1 to 10 after storage for 12 months at 30 ℃ was determined by reference to HG/T5437-2018, and the decomposition rate (initial content-post-storage content)/initial content × 100%.
