Problems solved by technology

[0004] Both azoxystrobin and tebuconazole can be used to control fungal diseases on fruit trees, peanuts, and cereals. However, with the increase of the application period, the resistance of fungal diseases to single agents increases year by year, and it is necessary to increase the dosage and use of drugs. The number of times can achieve the sterilization effect, which not only increases the cost, but also increases the environmental pressure

Embodiment 1

[0041] Example 1 85% Azoxystrobin Tebuconazole Water Dispersible Granules

[0042] Azoxystrobin 49%, tebuconazole 36%, foliar fertilizer potassium chloride 1.807%, diammonium hydrogen phosphate 3.197%, ammonium nitrate 1.946%, chelated iron 0.05%, dispersant sodium polycarboxylate 2.5%, alkyl Sodium phenolsulfonate 1.0%, calcium lignosulfonate 1.0%, wetting agent a-sulfo fatty acid methyl ester 0.5%, sodium a-olefin sulfonate 0.5%, fatty amide N-methyl taurine sodium salt 0.5% 100% of cornstarch, after the mixture is fully mixed, it is pulverized by ultra-fine airflow to obtain a 750-mesh fine powder, and then the resulting fine powder is kneaded by adding an appropriate amount of water in a kneader, and granulated by a rotary granulator. Dry at 50°C in a fluidized fluidized bed to obtain 85% azoxystrobin tebuconazole water dispersible granules.

Embodiment 2

[0043] Example 2 52% Azoxystrobin Tebuconazole Water Dispersible Granules

[0044] Azoxystrobin 30%, tebuconazole 22%, foliar fertilizer potassium chloride 1.807%, diammonium hydrogen phosphate 3.197%, ammonium nitrate 1.946%, chelated iron 0.05%, dispersant sodium polycarboxylate 2.5%, alkyl Sodium phenolsulfonate 1.0%, calcium lignosulfonate 1.0%, wetting agent a-sulfo fatty acid methyl ester 0.5%, sodium a-olefin sulfonate 0.5%, fatty amide N-methyl taurine sodium salt 0.5% , cornstarch make up 100%, after the mixture is fully mixed, carry out ultra-fine airflow pulverization to obtain 720 mesh fine powder, then add appropriate amount of water to the kneader to knead the obtained fine powder, and then granulate through the rotary disc granulator, Dry at 60°C in a fluidized fluidized bed to obtain 52% azoxystrobin tebuconazole water dispersible granules.

Embodiment 3

[0045] Example 3 85% Azoxystrobin Tebuconazole Water Dispersible Granules

[0046] Azoxystrobin 49%, Tebuconazole 36%, Dispersant sodium polycarboxylate 2.5%, Sodium alkylphenol sulfonate 1.0%, Calcium lignosulfonate 1.0%, Wetting agent a-sulfo fatty acid methyl ester 0.5% , 0.5% of sodium α-olefin sulfonate, 0.5% of fatty amide N-methyl taurine sodium salt, and 100% of cornstarch. After the mixture is fully mixed, it is pulverized by ultra-fine airflow to obtain a 730-mesh fine powder. The resulting fine powder is kneaded with an appropriate amount of water in a kneader, granulated by a rotary granulator, and dried in a fluidized fluidized bed at 55°C to obtain 85% azoxystrobin-tebuconazole water-dispersible granules.

Abstract

The invention discloses a fungicidal composition containing azoxystrobin and tebuconazole and application of the fungicidal composition. The composition takes azoxystrobin and tebuconazole as active ingredients, and a leaf fertilizer as a synergistic assistant. The fungicidal composition has a significant synergistic effect when the azoxystrobin, the tebuconazole and the leaf fertilizer are mixed, the advantages of the three components are fully played, the obtained product is excellent in quality and good in pesticide effect, the preparation method is simple, convenient to operate and less in energy consumption, and a plurality of fungal diseases of crops such as fruit trees, peanuts and cereal can be effectively prevented and treated. By adopting the composition, the nutrimental ingredients of the crops can be increased, the disease resistance of the crops is improved, the yield, the quality and the like of the crops are improved, meanwhile, the dosage and the use frequency of the pesticide are reduced, the economic cost is reduced, the residual quantity of the pesticide in agricultural products and environment is reduced, the resistance to pesticide of the fungal diseases also can be delayed, the service life period of the pesticide is prolonged, and the fungicidal composition has important economic significance, environmental significance and ecological significance.

Description

technical field [0001] The invention relates to a preparation method of a pesticide bactericidal composition, in particular to a bactericidal composition of azoxystrobin and tebuconazole, a preparation method and application thereof. The fungicide composition is suitable for various fungal diseases of crops such as fruit trees, vegetables, flowers and cereals. Background technique [0002] Azoxystrobin, English name: Azoxystrobin, chemical name: (E)-[2-[6-(2-cyanophenoxy)pyrimidin-4-yloxy]phenyl]-3-methoxymethyl acrylate . Azoxystrobin belongs to the methoxyacrylate fungicides and is a mitochondrial respiration inhibitor, that is, it inhibits the respiration of mitochondria by electron transfer between cytochrome b and C1. Azoxystrobin has a wide bactericidal spectrum and has good activity against almost all fungal diseases such as powdery mildew, rust, glume blight, net spot, scab, downy mildew, rice blast and dozens of diseases, suitable for For cereal crops, rice, pean...
