Embodiment 1

[0035] Embodiment 1: The fungicide fertilizer granule of the present invention is composed of the following raw materials: azoxystrobin, carrier fertilizer, dispersion aid, slow release agent, binder, filler. Based on the total weight of fungicide fertilizer granules, including: azoxystrobin 0.01%, carrier fertilizer 30%, dispersing aid 0.5%, slow release agent 0.1%, binder 0.1%, and the rest is filler.

[0036] like figure 1 As shown, mix azoxystrobin, dispersing aids, slow-release agents, binders, carrier fertilizers and the rest of the filler in a closed blending kettle, granulate by coating method, and dry at 110 ° C ~ 120 ° C When the water content of the granules is less than 3%, sieve, the particle size range is 2000μm ~ 4000μm, and after passing the inspection, the required fungicide fertilizer granules are obtained; the powder sieves are crushed and returned to the mixing tank for re-mixing, unqualified products After inspection and analysis, return to the mixing ta...

Embodiment 2

[0039] Embodiment 2: The fungicide fertilizer granule of the present invention is composed of the following raw materials: azoxystrobin, carrier fertilizer, dispersion aid, slow release agent, binder, filler. Based on the total weight of fungicide fertilizer granules, including: azoxystrobin 10%, carrier fertilizer 60%, dispersing aid 3%, slow release agent 2%, binder 5%, and the rest is filler.

[0040] The slow-release agent is 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. The preparation method is the same as in Example 1.

[0041]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, the zinc element content is 2% of ...

Embodiment 3

[0042] Embodiment 3: The fungicide fertilizer granule of the present invention is composed of the following raw materials: azoxystrobin, carrier fertilizer, dispersing aid, slow-release agent, binder, and filler. Based on the total weight of fungicide fertilizer granules, including: azoxystrobin 5%, carrier fertilizer 35%, dispersing aid 2%, slow release agent 1%, binder 3%, and the rest is filler.

[0043] Described sustained-release agent is polyvinyl alcohol. The binder is industrial gelatin. The dispersing aid is sweet potato starch. The filler is a mixture of calcium bicarbonate and white kaolin. The preparation method is the same as in Example 1.

[0044] The carrier fertilizer is a mixture of ammonium chloride and urea, 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 5% of the fungicide fertilizer granule. 4% of th...

Abstract

The invention relates to azoxystrobin-containing bactericide fertilizer granules. The bactericidal active ingredient is azoxystrobin; and based on the total weight of the bactericide fertilizer granules, the bactericide fertilizer granules comprise the following components: 0.01-10% of azoxystrobin, 30-60% of carrier fertilizer, 0.5-3% of dispersing aid, 0.1-2% of sustained-release agent, 0.1-5% of binder and the balance of packing. The bactericide fertilizer granules provided by the invention are mainly used for preventing and curing the diseases of the watermelon, cucumber, hot pepper and cotton at the seedling stage, wherein the diseases include fusarium wilt and damping off. The bactericide fertilizer granules provided by the invention are of great significance to effectively, scientifically and reasonably utilize the resources and protect the environment, and realize positive promotion effects on reducing the agricultural input and increasing both production and income of the agriculture.

Description

technical field [0001] The invention relates to a fertilizer granule, in particular to a bactericidal fertilizer granule containing azoxystrobin. Background technique [0002] Fusarium ( Fusarium ) Also known as Fusarium, saprophytic, weakly parasitic or parasitic, causing wilting, rot and other symptoms. For example, Fusarium oxysporum causes soybean root rot, and various specialized types of Fusarium oxysporum cause wilt of different plants. Fusarium oxysporum is a typical soil-dwelling fungus, which can survive chlamydospores in soil or diseased debris for 5 to 6 years. Fusarium oxysporum is spread in the field mainly through agricultural operations, rain, underground pests, nematodes, etc. , and can also be spread over long distances through infected seeds and seedlings. This kind of disease is easy to be popular for many years. Soil disinfection by chemical means and control of the accumulation of bacteria in the soil can effectively prevent and reduce the occurrence...
