Embodiment 1

[0035] Embodiment 1: According to the raw materials corresponding to Embodiment 1 in Table 1 and their weight ratios, a sufficient amount of bamboo vinegar or wood vinegar was left to stand for 5 to 8 months and then filtered to make mother liquor, and then 0.1 part of bitter bark Rattan, 0.1 part of osthole and 0.5 part of antioxidant are added to 5 parts of organic solvents for dissolving, and the colloid is ground and mixed evenly to make the oil phase, and then a small amount of bamboo (wood) vinegar is added to 5 parts of emulsifier, and after stirring As the water phase, mix the water phase and the oil phase through a colloid mill, then add a small amount of bamboo vinegar or wood vinegar to the remaining other additives according to their respective weight parts, and mix this mixture with the water phase and oil phase mixture Together, grind and mix evenly in a colloid mill, and finally add the remaining bamboo (wood) vinegar to make the total amount of bamboo (wood) vin...

example 1

[0054] The preparation method of example one compound insecticide is:

[0055] (1) Let the bamboo (wood) vinegar solution stand for 5 to 8 months, filter it, and collect it as mother liquor.

[0056] (2) According to the proportion, bitter bark vine, osthole and tocopherol are added to ethanol and ethyl acetate as the solvent to dissolve, and the oil phase is obtained by mixing evenly through the colloid mill; the colloid mill does not make special requirements, and can reach The effect of mixing is even.

[0057] (3) Add an appropriate amount of bamboo (wood) vinegar obtained in step (1) into the polyoxyethylene sorbitan fatty acid ester and castor oil polyoxyethylene ether as emulsifiers, stir and dissolve, and obtain an aqueous phase.

[0058] (4) Add the water phase to the oil phase, and mix evenly through a colloid mill.

[0059] (5) Add an appropriate amount of bamboo (wood) vinegar obtained in step (1) to the other additives, stir and dissolve, then add the mixture ob...

Abstract

The invention discloses a celastrus angulatus and cnidium lactone compounded pesticide which consists of the following raw materials in parts by weight: 0.1-5 parts of celastrus angulatus, 0.1-5 parts of cnidium lactone, 5-15 parts of solvent, 5-15 parts of emulsifier, 1-6 parts of dispersant, 0.5-2 parts of antioxidant, 0.5-1 part of stabilizer, 0.5-10 parts of penetrant, 1-10 parts of anti-freezing agent, 1-3 parts of antifoaming agent and the balance of bamboo vinegar liquid or wood vinegar liquid based on 100 parts. The pesticide is prepared by six steps of filtration of bamboo (wood) vinegar liquid, preparation of an oil phase, preparation of a water phase, preparation of a mixed solution, preparation of pesticidal suspension emulsion and the like, is mainly used for preventing pear gall midge, shows an obvious synergistic effect, and realizes a good field control effect. The pesticide disclosed by the invention prevents drug resistance of pests after long-time use, can be automatically degraded, is safe and efficient to use, avoids pollution, and has low cost and good persistence.

Description

technical field [0001] The invention relates to an insecticide compounded with plant-derived picroderm and osthole, which is mainly used for preventing and controlling agricultural pests such as pear gall midges, and a preparation method thereof. Background technique [0002] my country's pear tree cultivation area and output both rank first in the world. According to the statistics of the United Nations Food and Agriculture Organization (FAO), in 2009 China's pear tree harvest area was 1.258 million ha 2 , accounting for 72.3% of the world's total pear area; the total annual output is 14.388 million tons, accounting for 65.7% of the world's total output. Pear gall midge was a minor pest of pear trees in the past, and its damage was relatively light. However, in recent years, it has become a major pest of pears in major pear producing areas in my country. It can easily cause early leaf defoliation of pear trees and significantly affect yield and quality. At present, the con...
