Problems solved by technology

[0009] Benzimidazole fungicides have been widely used in agriculture for many years. The use of high density and large amount leads to serious resistance and shortened duration, which is not conducive to the sustainable development of the environment.
However, given that benzimidazole fungicides have better systemic properties and have therapeutic effects, in the current field of pesticides, benzimidazole fungicides are more cost-effective in terms of mode of action and cost, and still have great potential. room for improvement

Embodiment 1

[0039] Weigh 15% copper quinolate, 30% thiophanate-methyl, 5% fluopyram, 3% emulsifier Span-60# (common name: sorbitan monostearate), 5% diffusing agent NNO (alkyl naphthalene sulfonate), 2% wetting agent TERSPERSE 2500 (produced by Huntsman, USA), 1% xanthan gum, 5% ethylene glycol, 0.5% silicone defoamer (trade name: s -29 produced by Nanjing Sixin Applied Chemicals Co., Ltd.), and the balance is deionized water. The above-mentioned raw materials are processed through the processes of mixing, pre-crushing, crushing with a sand mill, mixing and blending, and packaging. Different parameter equipment can be selected according to the actual production for the pre-crushing and mixing process. The sand mill pulverization process of the suspending agent in this embodiment uses four sand mills, multi-stage series, using fine sand and coarse sand, the first sander is fully loaded with coarse sand, and the second sander is filled with 2 / 3 coarse sand. Sand and 1 / 3 fine sand, the thi...

Embodiment 2

[0041] Weigh 5% copper quinolate, 24% thiophanate-methyl, 6% fluopyram, 2% TERSPERSE 4894 (produced by Huntsman, USA), 4% agricultural milk 1601# (common name: triphenylethyl Phenol polyoxypropylene polyoxyethylene block polymer), 2% diffusion agent NNO, 1% magnesium aluminum silicate, 5% ethylene glycol, 0.5% formaldehyde, 0.5% silicone defoamer (trade name: s-29 Nanjing Sixin Applied Chemicals Co., Ltd.) and deionized water were added to 100% by weight. The above-mentioned raw materials are processed through the processes of mixing, pre-crushing, crushing with a sand mill, mixing and blending, and packaging. Different parameter equipment can be selected according to the actual production for the pre-crushing and mixing process. The sand mill pulverization process of the suspending agent in this embodiment uses four sand mills, multi-stage series, using fine sand and coarse sand, the first sander is fully loaded with coarse sand, and the second sander is filled with 2 / 3 coar...

Embodiment 3

[0043] Take by weighing 5% copper quinolate, 25% thiophanate-methyl, 8% fluopyram, 2% TERSPERSE 2700 (polycarboxylate, produced by Huntsman, U.S.), 4% dispersant Ufoxane 3A, 1% Pull apart powder BX (sodium dibutylnaphthalene sulfonate), 1% sodium lauryl sulfate (K-12), 2% polyvinylpyrrolidone, 1% white carbon black, and kaolin are added to 100% by weight. The above-mentioned raw materials are prepared through the conventional method for preparing water-dispersible granules, ie, mixing, ultrafine airflow pulverization, mixing, and granulating steps to prepare 38% copper quinolate · thiophanate-methyl · fluopicolide dispersible granules.

Abstract

The invention discloses fungicidal composition containing oxine-copper. Fungicidal effective constituents comprise oxine-copper, thiophanate-methyl and fluopicolide, wherein oxine-copper accounts for 1%-30% of the fungicidal composition in percentage by weight, thiophanate-methyl accounts for 5%-40% of the fungicidal composition in percentage by weight, fluopicolide accounts for 5%-10% of the fungicidal composition in percentage by weight, and the sum of content of the fungicidal effective constituents is 5%-80% of total weight of the composition. The composition can be used for preparing agriculturally allowable dosage forms such as suspending agents, water dispersible granules, wettable powder, dispersible oil suspensions or emulsion in water. The fungicidal composition has the advantages that the constituents are reasonably compounded, the fungicidal effect is good and activity and the fungicidal effect of the fungicidal composition are not realized by simply overlapping activity of the constituents; compared with an existing single preparation, the fungicidal composition not only has a remarkable fungicidal effect, but also has an obvious synergistic effect, and is good in crop safety. The fungicidal composition has an obvious control effect on grape grey mould.

Description

technical field [0001] The invention belongs to the technical field of compound pesticides, and relates to a bactericidal composition, which contains three active ingredients of copper quinolate, thiophanate-methyl and fluopyram. The invention also relates to the dosage form of the bactericidal composition and its application in agriculture. Background technique [0002] Copper preparations are one of the oldest types of agricultural fungicides, which have the advantages of broad antibacterial spectrum and are not easy to produce drug resistance. Inorganic copper preparations mainly composed of copper hydroxide and copper sulfate have been used for more than 200 years, but because they are difficult to be biodegraded, long-term and large-scale use has caused the accumulation of copper in the soil, which will affect the normal growth of plants and adverse effects on soil function. At present, the development and utilization of organic copper preparations has become a hot to...
