Embodiment 1
[0031] High stability pesticide composition, comprises the raw material of following mass parts:
[0032] Pichamid, 4 parts;
[0033] Pyriproxyfen, 8 parts;
[0034] Potassium hydrogen tartrate, 10 parts;
[0035] Mass fraction is 20% urea aqueous solution (solvent), 60 parts;
[0036] Dimethylformamide (solvent), 18 parts.
[0037] The production method of above-mentioned high stability pesticide composition, comprises the following steps:
[0038] S1. After mixing the pichamidin and the solvent evenly, heat to 50-60°C, and under the stirring condition of 70-80rpm, quickly add the potassium hydrogen tartrate, and continue to stir for 5-10min;
[0039] S2. Mix the pyriproxyfen and co-solvent evenly, add to the solution obtained in step 1, and keep stirring for 30-40 min while keeping the temperature at 50-60°C.
Embodiment 2
[0041] With embodiment 1, only the composition (mass parts) of composition is revised as:
[0042] Pichamid, 8 parts;
[0043] Pyriproxyfen, 24 parts;
[0044] Potassium hydrogen tartrate, 12 parts;
[0045] Mass fraction is 18% glycerol aqueous solution (solvent), 48 parts;
[0046] Dimethyl sulfoxide (solvent), 8 parts.
Embodiment 3
[0048] With embodiment 1, only the composition (mass parts) of composition is revised as:
[0049] Pichamid, 6 parts;
[0050] Pyriproxyfen, 15 parts;
[0051] Potassium hydrogen tartrate, 11 parts;

Abstract
The invention relates to the technical field of production of pesticide insecticides, in particular to a high stability pesticide composition and a production method thereof. The high stability pesticide composition is prepared from the following raw materials in percentage by mass: 4-8% of IPP, 8-24% of pyriproxyfen, 10-12% of monobasic potassium tartrate, 48-60% of a solvent and 8-18% of a cosolvent. The high stability pesticide composition which takes IPP and pyriproxyfen as active ingredients has an obvious synergic effect on brown planthopper and can slow down development of drug resistance of brown planthopper; monobasic potassium tartrate is taken as a stabilizer for resisting decomposition of IPP and pyriproxyfen, and the composition is unlikely to decompose and convenient to storeat a high temperature under interaction of the three; the production method of the high stability pesticide composition comprises the following steps: uniformly mixing IPP and the solvent, heating the mixture to 50-60 DEG C, quickly adding monobasic potassium tartrate under a stirring condition, and continuously stirring the mixture for 5-10min; and adding pyriproxyfen and the cosolvent to be mixed and dissolved and heating and stirring the mixture to prepare the high stability pesticide composition. The production method provided by the invention is simple in step and low in price of raw materials, and can be popularized on a large scale.
Description
technical field [0001] The invention relates to the technical field of production of pesticides and insecticides, in particular to a high-stable pesticide composition and a production method thereof. Background technique [0002] Pichridam is a new type of high-efficiency, broad-spectrum, low-toxicity neonicotinoid insecticide, which is mainly used to control Homoptera pests, and has a good control effect on rice planthoppers; different cis-structure of the agent, and different from the existing neonicotinoid insecticides, it is safe to the environment, humans, livestock, natural enemies of pests and other beneficial organisms, especially changing the high toxicity of neonicotinoid insecticides to bees The situation; pests have no resistance to it, and it is an environmentally friendly insecticide. [0003] Pyriproxyfen is an insect growth regulator that disrupts the growth of insects with phenyl ethers. It is a new type of insecticide that is similar to juvenile hormones. ...
