Embodiment 1

[0039] The formula is as follows:

[0040] Metalaxyl 3%

[0041] Tolclofos-methyl 5%

[0042] Ethanol isopropanol (1:1, mass) 20%

[0043] Alkylphenol ethoxylates 13%

[0044] Calcium dodecylbenzenesulfonate 12%

[0045] Polyvinyl alcohol 2%

[0046] Acid Scarlet 0.6%

[0047] Tributyl Phosphate 1.2%

[0048] water balance

[0049] Stir and emulsify the above-mentioned materials in an emulsification reactor at 15°C, cool the solution when it becomes a uniform transparent liquid, add film-forming agent, warning color and defoamer and mix evenly to obtain the seed treatment agent of the present invention.

[0050] The above-mentioned seed treatment agents were carried out at 0 ± 1°C for low temperature stability test and 54 ± 1°C for heat stability test (carried out heat storage and cold storage test according to the pesticide test) according to the method specified in the pesticide preparation standard. As a result, it was found that the The product does not have any oi...

Abstract

The invention discloses a nuisance free seed additive for preventing vegetable sprout term disease and its preparation method, wherein the seed additive is prepared from two of metalaxyl, Tolclofos-methyl or hymexaxzol by a predetermined proportion through specific process technology, the seed addictive also comprises surface active agent, dispersing agent, solvent, film-forming agent, and aposematic coloration.

Description

technical field [0001] The invention relates to a pesticide seed treatment agent, in particular to a compound pesticide seed treatment agent composed of metalaxyl and tolclofos-methyl, and further relates to a seed treatment agent for preventing and treating vegetable seedling diseases. Background technique [0002] Metalaxyl is a systemic fungicide, which can be absorbed by the roots, stems and leaves of plants, and transmitted to all parts of the plants to prevent and cure diseases. It is mainly used to prevent and control frost enzyme disease of vegetable crops. Its chemical name is: N-(2-methoxyacetyl)-N-(2,6-dimethylphenyl)-racemic-α-amino Methyl propionate, the preparation method and relevant performance data of metalaxyl have been reported on the published data of documents such as U.S. Patent US3882162, US4267365, Us4317916 and Chinese Patent 1051916 and "Pesticide Production and Synthesis" edited by Chen Wanyi. Many enterprises have produced the original drug of th...
