Embodiment 1

[0032] Example 1: The bactericidal medicinal fertilizer granule of the present invention is composed of the following raw materials: pyraclostrobin, carrier fertilizer, dispersion aid, slow release agent, binder and filler. Based on the total weight of fungicide fertilizer granules, including: pyraclostrobin 0.1%, carrier fertilizer 20%, dispersing aid 0.5%, slow release agent 0.1%, binder 0.1%, and the rest is filler.

[0033] like figure 1 As shown, the above-mentioned pyraclostrobin, dispersing aid, slow-release agent, binder, carrier fertilizer and the rest of the filler are mixed uniformly in a closed blending kettle, and granulated by coating method, at 110℃~120℃ Dry under conditions until the water content of the granules is less than 3%, sieve, and the particle size ranges from 2000 μm to 4000 μm. After passing the inspection, the required fungicide fertilizer granules are obtained; the powder sieved is crushed and returned to the mixing tank for re-mixing. The unqu...

Embodiment 2

[0036] Example 2: The bactericidal medicinal fertilizer granule of the present invention is composed of the following raw materials: pyraclostrobin, carrier fertilizer, dispersion aid, slow release agent, binder and filler. Based on the total weight of fungicide fertilizer granules, including: pyraclostrobin 5%, carrier fertilizer 40%, dispersing aid 3%, slow release agent 2%, binder 10%, and the rest is filler. The preparation method is the same as in Example 1. The slow-release agent is polyvinyl alcohol or gum arabic. The binder is industrial gelatin. The dispersing aid is sweet potato starch. The filler is a mixture of calcium bicarbonate and white kaolin.

[0037] Described carrier fertilizer is urea, and its N element nutrient content is 25% of the total weight of fungicide fertilizer granule, P element content is 10% of the total weight of fungicide fertilizer granule, and K element content is the total weight of fungicide fertilizer granule. 10% of the weight, th...

Embodiment 3

[0038] Example 3:The bactericidal medicinal fertilizer granule of the present invention is composed of the following raw materials: pyraclostrobin, carrier fertilizer, dispersion aid, slow release agent, binder and filler. Based on the total weight of fungicide fertilizer granules, including: pyraclostrobin 3%, carrier fertilizer 30%, dispersing aid 2%, slow release agent 1%, binder 5%, and the rest is filler. The preparation method is the same as in Example 1. The slow-release agent is polyvinyl alcohol or gum arabic. The binder is industrial gelatin. The dispersing aid is sweet potato starch. The filler is a mixture of calcium bicarbonate and white kaolin.

[0039] The carrier fertilizer is ammonium chloride, its N element nutrient content is 15% of the total weight of the fungicide fertilizer granule, the P element content is 5% of the fungicide fertilizer granule gross weight, and the K element content is 15% of the fungicide fertilizer granule. 6% of the total weigh...

Abstract

The invention relates to sterilization medical fertilizer granules, wherein the fungicide component of the medical fertilizer granules disclosed by the invention is pyraclostrobin; a carrier fertilizer component is composed of major elements, such as N, P and K, and trace elements, such as zinc, boron; and according to the total weight of the medical fertilizer granules, the medical fertilizer granules comprise the following components: 0.1-5% of the pyraclostrobin, 20-40% of the carrier fertilizer, 0.5-3% of dispersing auxiliary, 0.1-2% of a slow release agent, 0.1-5% of a binding agent, and the balance of a filling material. The sterilization medical fertilizer granules disclosed by the invention have an important significance for protecting the environment and play a positive promotion role in reducing agricultural input and increasing both production and income of agriculture.

Description

technical field [0001] The invention relates to a bactericidal medicinal fertilizer granule, the bactericidal active ingredient is pyraclostrobin, and is used for preventing and treating watermelon wilt. Background technique [0002] Fusarium wilt of watermelon is caused by the infection of Fusarium oxysporum, a fungus of the subphylum Imperfecta. It is a soil-borne disease and is known as "plant cancer". The part above the ground stem withers and dies, the lack of seedlings reduces the yield, and the pathogen can also pollute the soil, and the infectivity can reach 4 to 7 years, so that the watermelon cannot be planted continuously, especially when the soil moisture content is high and the humidity is high. The disease is serious. [0003] At present, the pesticides used in production to prevent and control watermelon wilt mainly include hymexazol, carbendazim, thiophanate-methyl, thiram, sulfur, and copper hydroxide. [0004] Pyraclostrobin, common name in English: pyracl...
