Embodiment 1

[0030] Weigh 30% quinoline copper, 15% kasugamycin, 4% emulsifier Nongru 700# (common name: alkylphenol formaldehyde resin polyoxyethylene ether), 5% dispersant TERSPERSE 2020 (produced by Huntsman, USA) ), 2% wetting agent TERSPERSE2500 (produced by Huntsman, USA), 1.5% viscosity modifier xanthan gum, 5% antifreeze ethylene glycol, 0.5% silicone defoamer (trade name: s-29 Nanjing Si New Applied Chemicals Company), the balance is deionized water.

[0031] 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 2

[0033] Weigh 40% copper quinoline, 10% kasugamycin, 3% TERSPERSE 4894 (produced by Huntsman, U.S.), 2% TERSPERSE 2500 (produced by Huntsman, U.S.), 4% diffusing agent NNO, 1.5% bentonite, 1% xanthan gum, 8% ethylene glycol, 0.5% formaldehyde, 0.5% silicone defoamer (trade name: s-29 produced by Nanjing Sixin Applied Chemicals Co., Ltd.), and deionized water are added to 100% by weight.

[0034] 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 third sand mill is filled...

Embodiment 3

[0036] Take by weighing 25% copper quinoline, 15% kasugamycin, 3% TERSPERSE 2700 (polycarboxylate, produced by Huntsman, U.S.), 3% sodium lignosulfonate, 1% pull open powder BX (dibutyl sodium naphthalenesulfonate), 1% sodium lauryl sulfate (K-12), 2% PVA (molecular weight 2000), 2% polyvinylpyrrolidone, 0.5% white carbon black, and kaolin 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 water-dispersible granules with 40% copper quinoline·kasugamycin as the active ingredient.

Abstract

The invention discloses a bactericidal composition containing quinoline copper and kasugamycin. Effective components of the bactericidal composition comprise a first active component which is quinoline copper and a second active component which is kasugamycin; the weight ratio of the first active component to the second active component is (1 to 7)-(15 to 1); the sum of the content of the first active component and the second active component is 5-80% of the total weight of the composition. The composition can be prepared into preparations such as suspension agents, water dispersible granules and wettable powder and the like which are allowed to be used in agriculture. The composition is reasonable in compound and excellent in bactericidal effect; the activity and the bactericidal effect of the composition are not simple superposition of the activity of the components; compared with the existing signal preparation, the composition has obvious synergistic effect besides obvious bactericidal effect, is high in safety to crops, and has obvious effects of preventing and treating rice blast.

Description

technical field [0001] The invention belongs to the technical field of compound pesticides, and relates to a bactericidal composition, which contains quinoline copper as the first active ingredient and kasugamycin as the second active ingredient. 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 ha...
