Embodiment 1

[0028] Embodiment 1 prepares capsule wall material

[0029] Mix 25g of urea and 50g of formaldehyde evenly (that is, the weight ratio of urea and formaldehyde is 1:2), add 75g of deionized water, and adjust the pH to 8 with NaOH solution with a mass fraction of 5%, at 70°C, at 600rpm Stir at a high speed, keep at 70°C for 1 hour to generate a viscous and transparent aqueous solution of urea-formaldehyde resin prepolymer, which is the capsule wall material.

Embodiment 2

[0030] Example 2 Preparation of 20% pyraclostrobin · rice blastling microcapsule suspension

[0031] Raw material components: by mass percentage, 5% pyraclostrobin, 15% rice blastin, 5% xylene, 2% Nongru 602, 20% capsule wall material, 3% emulsifier BY125, 0.2% xanthan Glue, 3% ethylene glycol, 0.2% Cathone, make up water to 100%.

[0032] The preparation steps are as follows:

[0033] (1) Mix pyraclostrobin and rice blastin evenly in proportion, heat in a constant temperature oven at 54°C for 1-2 hours, take it out, dissolve the semi-molten mixture in 5g of xylene, and add 2g of pesticide Milk 602 is fully emulsified, stirred evenly at room temperature at a speed of 1000-1200rpm, to obtain a pyraclostrobin / blastizolin mixed solution;

[0034](2) At normal temperature, pour 25g of the urea-formaldehyde resin prepolymer aqueous solution obtained in Example 1 into the reaction kettle with the pyraclostrobin / blastizolin mixed solution obtained in step (1) and mix, and use the m...

Embodiment 3

[0036] Example 3 15% pyraclostrobin · rice blastling microcapsule suspension

[0037] Raw material components: by mass percentage, 5% pyraclostrobin, 10% rice blastin, 2% Nongru 1601, 5% xylene, 15% capsule wall material, 1% emulsifier AEO-3P, 0.24% Xanthan gum, 3% propylene glycol, 0.2% sodium benzoate, made up to 100% with water.

[0038] Preparation:

[0039] (1) Put 97% pyraclostrobin technical substance and 96% rice blastin technical substance in a constant temperature oven at 54 DEG C and heat for 1-2 hours in proportion, and dissolve the mixture in semi-molten state in xylene after taking it out, Add Nongru 1601 for full emulsification, and stir evenly at room temperature at a speed of 1000-1200d / min to obtain a pyraclostrobin / daofengling mixture;

[0040] (2) Pour the capsule wall material obtained in Example 1 and the above-mentioned pyraclostrobin / diablastin mixture into the reaction kettle for mixing, and adjust the pH value to about 5 with 2% hydrochloric acid, a...

Abstract

The invention discloses a Pyraclostrobin / Isoprothiolane microcapsule suspension, a preparation method therefor and an application of the Pyraclostrobin / Isoprothiolane microcapsule suspension. The microcapsule suspension is prepared from the following ingredients in percentage by weight: 2.5% to 5% of Pyraclostrobin, 10% to 21% of Isoprothiolane, 3% to 10% of capsule-core solvent, 15% to 25% of capsule wall material, 3% to 7.5% of emulsifier, 3.4% to 4.7% of auxiliaries and the balance of water. Compared with the prior art, the microcapsule suspension has the advantages that the microcapsule suspension is prepared from Pyraclostrobin and Isoprothiolane crude pesticides through compounding and microcapsulation technologies, and the two kinds of pesticide ingredients are encapsulated in non-toxic capsule membranes, so that the contact toxicity of pesticide products can be lowered, and the stability of effective ingredients is further improved greatly; in addition, the effective control time of the products can be prolonged obviously, so that the repeated consumption of pesticides can be effectively avoided, and the pollution to environments is alleviated; and the conventional chemical raw materials are used, so that the comprehensive cost is low, the microcapsule suspension is in line with the direction of development of pesticide preparations, and the application prospect is relatively extensive.

Description

technical field [0001] The invention relates to the technical field of preparation of pesticides, in particular to a pyraclostrobin / daofengling microcapsule suspension and its preparation method and application. [0002] technical background [0003] Pesticides play a very important role in the prevention and control of crop diseases, insects and weeds, and in generating agricultural income. With the rapid development of modern science and technology and the enhancement of people's awareness of environmental protection, the creation of new pesticides needs to meet the new requirements of "ultra-efficient, non-polluting, and non-toxic". Since the creation of new pesticides is not only time-consuming, but also requires huge development costs, general pesticide companies and scientific research institutions cannot afford the research and development. Therefore, advanced technologies are used to process and modify the formulations of existing pesticides to improve the effectivene...
