Embodiment 1、41
[0042] The preparation of embodiment 1,41% glyphosate isopropylamine salt soluble agent
[0043] 0.1g of 5-aminolevulinic acid, 4g of sucrose, and 10g of water were added and mixed evenly to obtain a pretreatment solution. 300g of glyphosate, 116g of isopropylamine, and 2g of polyoxyethylene alkylamine were reacted in water for 4 hours at room temperature, and 10g of pretreatment was added. The treatment solution was stirred evenly, and the volume of water was adjusted to 1000 mL to obtain a 41% soluble solution of glyphosate isopropylamine salt.
Embodiment 2、2
[0044] The preparation of embodiment 2,2.5% cis-cypermethrin microemulsion
[0045] 0.5g of 5-aminolevulinic acid, 20g of sucrose, and 50g of water were added and mixed evenly to obtain a pretreatment solution, and 25g of cis-cypermethrin, 43g of calcium dodecylbenzenesulfonate, and 107g of styrenephenol polyoxyethylene ether were mixed and stirred evenly to obtain For the oil phase, slowly add the oil phase to 50 g of the pretreatment liquid and the water phase obtained by replenishing the total amount of 1000 g with water, stir evenly to form a stable liquid, and obtain a 2.5% cis-cypermethrin microemulsion.
Embodiment 3、45
[0046] Embodiment 3, the preparation of 45% prochloraz aqueous emulsion
[0047]1.2g of 5-aminolevulinic acid, 36g of sucrose, and 60g of water were added and mixed evenly to obtain a pretreatment solution, 450g of prochloraz, 200g of solvent oil S-100A, 60g of emulsifier 600 # Mix to form an oil phase, 2g magnesium aluminum silicate, 50g propylene glycol, 60g pretreatment liquid and water to form a water phase, slowly drop the water phase into the oil phase, stir while adding, make up to 1000g with water, and get 45% Prochloraz water emulsion.

Abstract
The invention provides a synergistic method for liquid pesticide preparations and the synergist used. The synergist consists of 5-aminolevulinic acid and sucrose. Dissolving 5-aminolevulinic acid and sucrose in water or dimethyl sulfoxide, adjusting the pH value of the resulting solution to 5.8-6.5 to obtain a pretreatment solution, mixing the pretreatment solution with water as a liquid pesticide preparation process According to the conventional process, the pesticide components are made into corresponding liquid pesticide preparations. The inventors of the present invention use 5-aminolevulinic acid and sucrose to form effective synergistic components of pesticide preparations through screening to regulate physiological activities such as plant stomata, respiration, assimilate transport, and promote the effective absorption of pesticide preparations by plants. The use effect of pesticides is conducive to achieving the purpose of reducing pesticide application and increasing efficiency.
Description
technical field [0001] The invention belongs to the field of pesticides, and in particular relates to a synergistic method for liquid pesticide preparations and a synergist used therefor. Background technique [0002] Pesticide application reduction and efficiency enhancement technology is an extremely important part in the field of plant protection, especially when it is difficult to develop new pesticides and the resistance of pests is gradually strong, the purpose of increasing efficiency is often achieved by increasing the utilization rate of pesticides. [0003] Whether it is a dicotyledon or a grass, it consists of three parts: the epidermis, the mesophyll, and the veins. Among them, the characteristics of the epidermis are the focus of attention of pesticide workers. The epidermis is composed of epidermal cells, stomata, epidermal hairs, and heterocysts. The epidermis is usually covered with a waxy stratum corneum, the main component of which is lipids. Due to the ...
