Problems solved by technology

However, at present, the Institute of Drug Control of the Ministry of Agriculture clearly stipulates that the three-component compound pesticide cannot pass the registration, so the patent application has no actual industrial application value
Moreover, in this patent application document, it is not stated what kind of beneficial effects will be produced by selecting two kinds of fungicides, so choosing two kinds of fungicides will undoubtedly increase the operating procedures and costs in the production process, and the more types of raw materials used, The more difficult it is to control the quality of the production process, and the control effect of the seed coating agent applied for in this patent on diseases and insect pests has not been effectively supported by experimental data

Embodiment Construction

[0031] 1. Preparation of phoxim mother liquor: Put phoxim crude oil, trideceth (5) sulfate Eon50, sodium salt of naphthion phenolic condensate, AL44L, methanol, and n-butanol into the reactor Stir for 30 minutes to prepare 45% phoxim mother liquor for later use. When preparing the seed treatment agent of the present invention, phoxim crude oil must be prepared into phoxim mother liquor for use.

[0032] 2. Preparation of seed coating agent: add the raw materials except film-forming agent into the reaction kettle in the proportion shown in the following table, start the high-speed shearing emulsifier, stir and coarsely grind, make it fully mixed and dispersed, and then press 1:1.5 The ratio of material to sand (volume ratio) is put into the sand mill for grinding, and defoamer is added as appropriate during the sanding process (when the surface of the slurry exceeds the original water level by 15cm, the defoamer needs to be added), and after grinding for a certain period of time , ...

Abstract

The invention discloses an effective seed treating agent with low toxicity which is prepared by active components and non-active components. The active components relate to a phoxim and a tebuconazole, wherein, the weight portion percentage of the phoxim and the tebuconazole is 3 to 12; the weight percentage content of the tebuconazole in the treating agent is 0.1 to 5 percent. Compared with the prior art, the invention can effectively control various diseases and insect pests and the controlling effects on maize head smut and corn rust can respectively reach 93.75 percent and 70.52 percent. The invention has no bad effects on environment, humans and animals, seed burgeoning and plant growing, which reduces the varieties of raw materials, simplifies the manufacture process and is easier to control the product quality.

Description

Technical field [0001] The invention relates to an agricultural seed treatment agent, in particular to a seed treatment agent compounded with phoxim and tebuconazole. Background technique [0002] Modern seed treatment technology is developed based on traditional seed soaking and seed dressing technology. It uses seeds as a carrier, slow-release of fertilizers as the key technology, processing technology as a means, and coating machinery as the support, integrating biology, chemical engineering, pesticides, and machinery. Seed processing technology integrating subject research results. At present, it is mostly compounded with high-toxic insecticides such as carbofuran, phorate, etc. and common fungicides such as thiram, carbendazim, etc., which have the disadvantages of high toxicity, high residue and low control effect, and the cost of medicine Higher. [0003] The Chinese patent application with publication number CN1559216 discloses a seed coating agent for the prevention and ...
