Embodiment 1

[0089] Example 1 Efficacy Test of 60% Flusilazole·Meconazole WP in Controlling Pear Scab

[0090] Flusilazole 50%, metconazole 10%, polycarboxylate 5%, sodium lignosulfonate 3%, silkworm excrement 2%, diatomaceous earth to 100%, the mixture is jet milled to obtain 60% fluoride Silazole metconazole wettable powder. The ratio is 6000 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 7 days and 14 days after the last spraying. The effects of preventing and treating pear scab 7 days and 14 days after the drug were 90.8% and 96.2% respectively. The 40% flusilazole EC and the 60g / L metconazole water emulsion were diluted 7500 times and 600 times respectively in the same way. The control effects were 71.8% and 72.5% respectively 14 days after treatment.

[0091] In this embodiment, flusilazole can be replaced with one of tetraflumezole, t...

Embodiment 2

[0092] Example 2 Drug Efficacy Test of 60% Tricyclazole Meconazole Water Dispersible Granules for Controlling Rice Blast

[0093]40% tricyclazole, 20% metconazole, 4% calcium salt of alkylbenzenesulfonate, 3% sodium tripolyphosphate, 3% wetting and penetrating agent F, 1% ammonium sulfate, bentonite to 100%, mixed Obtain 60% tricyclazole metconazole water-dispersible granules. The proportion is diluted and sprayed at 15 g / mu, sprayed at the early stage of the disease, sprayed once every 7 days, and sprayed twice in total. 7 days and 14 days after the last spraying, the disease index was investigated and the control effect was calculated. The effects of controlling rice blast 7 days and 14 days after the application were 91.2% and 96.8%, respectively. The 20% tricyclazole wettable powder and the 60g / L metconazole water emulsion followed the same method, respectively 80 g / mu and 75 g / mu diluted use, 14 days after the drug control effect were 72.8% and 71.2%.

Embodiment 3

[0095] Example 3 Efficacy test of 48% epoxiconazole·metconazole microemulsion for controlling banana leaf spot

[0096] Econazole 40%, Meconazole 8%, Acetone 10%, Nongru 500# 8%, Isobutanol 5%, Hydroxyethylcellulose 2%, Sodium Sorbate 2%, Silicone defoamer 0.5% , deionized water was added to 100%, mixed to prepare 48% epoxiconazole-meconazole microemulsion. The ratio is 3500 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 7 days and 14 days after the last spraying. 7 days and 14 days after the drug, the effects of preventing and treating banana leaf spot were 90.3%, 95.3%, respectively. The 12.5% ​​econazole suspension concentrate and the 60g / L metconazole emulsion were diluted 1000 times and 600 times respectively in the same way. The control effects were 66.3% and 73.4% respectively 14 days after treatment.

Abstract

The invention discloses a pesticide composition, which comprises metconazole and one of triazole bactericides such as flusilazole, epoxiconazole, tetraconazole, tricyclazole and flutriafol, wherein the weight part ratio of the two active ingredients in the pesticide composition is 80:1-1:80. The pesticide composition at least comprises a surfactant to contribute to dispersing the active ingredients in water during application. The bactericide composition has protecting, treating and killing activities, can be used for various crops, such as wheat, rice, vegetables, fruit trees and the like, and prevents and controls various plant diseases caused by pathogenic bacteria of aseomycotina, basidiomycolina and deuteromycotina.

Description

technical field [0001] The invention belongs to the field of agricultural fungicides, and relates to the preparation and application of a metconazole-containing pesticide composition. Background technique [0002] Metconazole, a new triazole fungicide developed by Kureha Chemical Company in Japan in the early 1990s, molecular formula: C 17 h 22 ClN 3 O, structural formula: [0003] [0004] Meconazole is an inhibitor of C-14 demethylase in ergosterol biosynthesis. Although the mechanism of action is the same as other triazole fungicides, the activity spectrum is quite different. Both isomers have bactericidal activity, but the activity of the cis form is higher than that of the trans form. The fungicidal spectrum of metconazole is very broad and its activity is excellent. Field application of metconazole has excellent effects on the plant diseases of Septoria, Fusarium and Puccinia of cereal crops. Compared with traditional fungicides, metconazole has a very low do...
