Embodiment 140

[0099] Example 140% Hexaconazole · Enoxastrobin Suspoemulsion Control Efficacy Test of Apple Leaf Spot

[0100]Hexaconazole 10%, Ethoxystrobin 30%, Polycarboxylate 3%, Lignosulfonate 3%, Sodium Dodecyl Benzene Sulfonate 4%, Nonylphenol Polyoxyethylene Ether Modified Phosphate 3%, 6% acetone, 0.5% xanthan gum, 3% propylene glycol, and deionized water were added to 100%, and mixed to prepare a 40% hexaconazole-estrostrobin suspoemulsion. The ratio is 4500 times diluted and sprayed, sprayed at the early stage of the disease, sprayed once every 7 days, and sprayed 3 times in total, and investigated the disease index and calculated the control effect 3 days, 14 days, and 30 days after the last spraying. 3 days, 14 days, and 30 days after the application, the effects of preventing and treating apple spot defoliation were 93.35%, 97.46%, and 92.36%, respectively, and 25% hexaconazole suspension concentrate and 25% enoxastrobin EC followed the same method, respectively pressing 4000 t...

Embodiment 260

[0102] EXAMPLE 260% Efficacy Test of Trifazol·Enotristrobin Water-Dispersible Granules for Controlling Cucumber Powdery Mildew

[0103] 20% of trifamelazol, 40% of trifloxystrobin, 4% of calcium salt of alkylbenzenesulfonate, 3% of sodium tripolyphosphate, 3% of wetting and penetrating agent F, 1% of ammonium sulfate, adding bentonite to 100%, and mixing Prepared 60% flutriafol · erythoxystrobin water dispersible granules. The ratio is 5000 times diluted and sprayed, sprayed at the early stage of the disease, sprayed once every 7 days, a total of 2 sprays, and investigated the disease index and calculated the control effect 3 days, 14 days, and 30 days after the last spraying. 3 days, 14 days, and 30 days after the application, the effects of controlling cucumber powdery mildew were 94.5%, 98.3%, and 93.2%, respectively. The 50% triazol wettable powder and the 25% enoxastrobin EC followed the same method, respectively, by 3000 times and 1000-fold dilution, the preventive effe...

Embodiment 360

[0105] EXAMPLE 360% Tricyclazole Ethoxystrobin WP WP Control Efficacy Test of Wheat Rust

[0106] Tricyclazole 30%, erythoxystrobin 30%, polycarboxylate 5%, sodium lignosulfonate 3%, silkworm excrement 2%, diatomaceous earth add to 100%, the mixture carries out airflow pulverization, mixes and makes 60 % Tricyclazole Ethoxystrobin wettable powder. The proportion is diluted and sprayed at 12 g / mu, sprayed at the early stage of the disease, sprayed once every 7 days, and sprayed twice in total. Investigate the disease index and calculate the control effect 3 days, 14 days, and 30 days after the last spraying . 3 days, 14 days, and 30 days after the medicine, the effects of preventing and treating wheat rust were 92.6%, 97.7%, and 91.8%, respectively, and 25% tricyclazole wettable powder and 25% enoxastrobin emulsifiable concentrate were used in the same way, respectively at 40 g / Mu and 50 g / mu dilution are used, and the control effects are 71.9% and 73.2% respectively 14 days...

Abstract

The invention discloses a bactericidal composition containing enostroburin and a triazole compound. The bactericidal composition comprises two active components of enostroburin and any one of flutriafol, hexaconazole, tricyclazole, triadimenol and difenoconazole, wherein flutriafol, hexaconazole, tricyclazole, triadimenol and difenoconazole belong to triazole compounds. The weight part ratio of the two active components of the bactericidal composition is in a range of 60:1 to 1:60. The bactericidal composition comprises at least one surfactant beneficial to dispersion of the active components in water during use of the bactericidal composition. The bactericidal composition has activities of protection, treatment and eradication, is applicable to multiple crops such as wheat, paddy rice, vegetables, fruit trees, etc. and can prevent and treat multiple diseases such as downy mildew, rust, powdery mildew, leaf spot, cladosporium cucumerinum, rice blast, etc.

Description

technical field [0001] The invention belongs to the field of agricultural fungicides and relates to the preparation and application of a fungicide composition containing enostrostrobin. Background technique [0002] Enostroburin, molecular formula: C 22 h 27 ClNO 4 , chemical name: methyl α-[[[[4-(4-chlorophenyl)-but-3-en-2-yl-]imino]methyl]phenyl-β-methoxyacrylate. [0003] The broad-spectrum fungicides of erythoxystrobin are a new class of pesticides successfully developed from the natural product Strobilurins as fungicide lead compounds, belonging to the methoxyacrylate fungicides. The principle of action of this type of agent is to inhibit the respiration of fungal mitochondria, and inhibit the potential transmission of mitochondria through the combination of the Q0 part of the cytochrome bc1 complex, thereby destroying the energy synthesis of pathogenic bacteria and playing a bactericidal effect. It has the characteristics of high efficiency, broad spectrum, protect...
