Embodiment 1

[0097] Example 1 Drug efficacy test of 40% imidazole trifloxystrobin suspoemulsion in controlling pear scab

[0098] imidazole 30%, trifloxystrobin 10%, polycarboxylate 3%, lignosulfonate 3%, sodium dodecylbenzenesulfonate 4%, nonylphenol polyoxyethylene ether modified phosphate 3 %, acetone 6%, xanthan gum 0.5%, propylene glycol 3%, deionized water to 100%, mixed to prepare 40% imidazole trifloxystrobin suspoemulsion. The ratio is 3000 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 and 14 days after the last spraying. 3 days and 14 days after the application, the effects of preventing and treating pear scab were 93.35% and 96.46%, respectively. The 15% imidazole wettable powder and the 12.5% ​​trifloxystrobin EC were diluted 1500 times and 600 times respectively in the same way. The control effects were 71.8% and 72.5% resp...

Embodiment 2

[0100] Example 2 Efficacy test of 60% epoxiconazole trifloxystrobin water dispersible granules for controlling banana leaf spot

[0101] Flueconazole 20%, trifloxystrobin 40%, alkylbenzenesulfonate calcium salt 4%, sodium tripolyphosphate 3%, wetting and penetrating agent F 3%, ammonium sulfate 1%, bentonite to 100%, mixed A 60% epoxiconazole trifloxystrobin water-dispersible granule was obtained. The ratio is 4000 times diluted and sprayed, sprayed at the early stage of the disease, and sprayed once every 7 days, a total of 3 sprays, and the disease index was investigated 3 days and 14 days after the last spraying and the control effect was calculated. 3 days and 14 days after the drug, the effects of preventing and treating banana leaf spot were 94.2%, 97.8%, respectively, and 125g / L epoxiconazole suspension concentrate and 12.5% ​​trifloxystrobin emulsifiable concentrate were used by diluting 1000 times and 500 times respectively according to the same method. The control e...

Embodiment 3

[0103] Example 3 Efficacy Test of 60% Tricyclazole Trifloxystrobin WP for Controlling Rice Blast

[0104] Tricyclazole 30%, Trifloxystrobin 30%, Polycarboxylate 5%, Sodium Lignosulfonate 3%, Silkworm excrement 2%, Diatomaceous earth added to 100%, the mixture was jet milled, mixed to obtain 60% Tricyclazole·trifloxystrobin wettable powder. The proportion is diluted and sprayed at 20 g / mu, sprayed at the early stage of the disease, sprayed once every 7 days, and sprayed twice in total. 3 days and 14 days after the last spraying, the disease index was investigated and the control effect was calculated. 3 days and 14 days after the application, the effects of controlling rice blast were 92.3%, 96.7%, respectively, and 20% tricyclazole wettable powder and 12.5% ​​trifloxystrobin emulsifiable concentrate were treated in the same way, respectively at 80 g / mu and 100 g / mu When used in dilution, the preventive effects were 69.7% and 72.8% respectively 14 days after treatment.

Abstract

The invention discloses a bactericidal composition containing trifloxystrobin and triazole, which comprises the following active ingredients: trifloxystrobin and one of imidazole, epoxiconazole, ipconazole, tricyclazole and myclobutanil which serve as triazole compounds, wherein a weight ratio of the trifloxystrobin to the triazole compounds ranges from 60:1 to 1:60. The pesticidal composition at least contains one surfactant, so that the active ingredients are easy to disperse in water during application. The bactericidal composition has the activity of protection, control and eradication, and can be used for preventing and controlling various diseases such as downy mildew, rust diseases, powdery mildew, leaf spot, cladosporium cucumerinum, rice blast and the like in various crops such as wheat, paddy, vegetables, fruits and trees and the like.

Description

Technical field [0001] The invention belongs to the field of agricultural fungicides and relates to the preparation and application of a trifloxystrobin-containing pesticide composition. Background technique [0002] Trifloxystrobin, molecular formula: C 20 H 19 F 3 N 2 O 4 , Chemical name: Methyl (E)-methoxyimino-{(E)-α-[1-(α,α-trifluoro-m-tolyl)-ethyleneaminooxy]-o Tolyl}ethyl acetate. Trifloxystrobin broad-spectrum fungicides are a new class of fluorinated fungicides successfully developed from the natural product Strobilurins as lead fungicide compounds. It has the characteristics of high efficiency, broad spectrum, protection, treatment, eradication, penetration, systemic activity, resistance to rain erosion, and long lasting effect. It is effective against strains resistant to 1,4-demethylase inhibitors, benzamides, dicarboxylamines and benzimidazole, and has no cross-resistance with existing fungicides. It has good activity against almost all fungal diseases (...
