Embodiment Construction

[0046] A bactericidal granule containing metalaxyl and hymexyl of the present invention is composed of the following raw materials: based on the total weight of the granule, wherein: metalaxyl 0.1% to 10%, hymexyl 0.1% to 10%, carrier 30%~60%, dispersing aid 0.5%~3%, sustained release agent 0.1%~2%, binder 0.1%~5%, and the rest is filler.

[0047] Such as figure 1 As shown, 0.1%~10% metalaxyl, 0.1%~10% hymexyl, 30%~60% carrier, 0.5%~3% dispersion aid, 0.1%~2% sustained release agent, 0.1%~ 5% binder and the rest of the filler are mixed evenly in a closed blending kettle, granulated by coating method, dried at 110°C to 120°C until the water content of the granules is less than 3%, sieved, and the particle size ranges from 2000μm to 4000μm. After passing the inspection, the required granules are obtained; the powder sieved is crushed and returned to the mixing tank for remixing, and the unqualified products are returned to the mixing tank for remixing after inspection and analys...

Abstract

The invention relates to sterilization granules containing metalaxyl and hymexazol and a preparation method thereof. The granules comprise the following components in percentage by weight: 0.1-10 percent of metalaxyl, 0.1-10 percent of hymexazol, 30-60 percent of carrier, 0.5-3 percent of dispersion assistant, 0.1-2 percent of slow-release preparation, 0.1-5 percent of binding agent and the balance of fillers. The sterilization granules are pelletized by adopting the envelope method. The granules and the method effectively, scientifically and rationally use resources, have important significance on environmental protection, and achieve active promotion effect on reduction of agricultural investment and increment of agricultural yield and incomings.

Description

technical field [0001] The invention relates to a pesticide granule and a preparation method thereof, in particular to a fungicidal granule containing metalaxyl and hymexyl and a preparation method thereof. Background technique [0002] Metalaxyl, an inhibitor of ribosomal RNA I synthesis. Systemic fungicides have protective and therapeutic effects, can be absorbed by the roots, stems and leaves of plants, and are transferred to various organs of plants along with the water transport in the body. It has two-way conductivity, and the duration of effect is 10-14 days, and the duration of soil treatment can exceed 2 months. It is effective for various crop diseases caused by downy mildew, phytophthora and rot. [0003] Hymexazol, a systemic fungicide, is also a soil disinfectant, which has a good preventive effect on damping-off caused by pythium and fusarium. The drug combines with iron and aluminum ions in the soil to inhibit the germination of spores. Hymexazol can be abs...
