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.

Example Embodiment

[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 polycarboxylate 2.5%, alkyl Sodium phenol sulfonate 1.0%, calcium lignosulfonate 1.0%, wetting agent a-sulfo fatty acid methyl ester 0.5%, a-olefin sulfonate sodium 0.5%, fatty amide N-methyl taurine sodium salt 0.5% , Corn starch to make up 100%. After the mixture is fully mixed and evenly mixed, it is pulverized by ultra-fine jet to obtain 750 mesh fine powder. Then the obtained fine powder is kneaded by adding an appropriate amount of water in a kneader, and then granulated by a rotary granulator. Drying in a boiling fluidized bed at 50°C will obtain 85% azoxystrobin·tebuconazole water dispersible granules.

Example Embodiment

[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 polycarboxylate 2.5%, alkyl Sodium phenol sulfonate 1.0%, calcium lignosulfonate 1.0%, wetting agent a-sulfo fatty acid methyl ester 0.5%, a-olefin sulfonate sodium 0.5%, fatty amide N-methyl taurine sodium salt 0.5% , Corn starch make up 100%, after the mixture is fully mixed and evenly mixed, it is pulverized by ultra-fine jet to obtain 720 mesh fine powder, and then the obtained fine powder is kneaded by adding an appropriate amount of water in a kneader, and then granulated by a rotary granulator. Dried in a boiling fluidized bed at 60°C to obtain 52% azoxystrobin·tebuconazole water dispersible granules.

Example Embodiment

[0045] Example 3 85% azoxystrobin·tebuconazole water dispersible granules

[0046] Azoxystrobin 49%, tebuconazole 36%, dispersant polycarboxylate 2.5%, alkylphenol sodium sulfonate 1.0%, calcium lignosulfonate 1.0%, wetting agent a-sulfo fatty acid methyl ester 0.5% , 0.5% sodium a-olefin sulfonate, 0.5% fatty amide N-methyl taurine sodium salt, 100% corn starch supplement, the mixture is fully mixed and uniform, and then subjected to ultra-fine jet pulverization to obtain 730 mesh fine powder. The obtained fine powder is kneaded with an appropriate amount of water in a kneader, granulated by a rotary granulator, and dried in a boiling fluidized bed at 55°C to obtain 85% azoxystrobin·tebuconazole water dispersible granules.
