Embodiment 1

[0017] Example 1 Indoor Toxicity Test of Cyprodinil and Propiconazole Mixed to Wheat Powdery Mildew

[0018] Indoor determination of inhibitory effect on wheat powdery mildew. The growth rate method was used for the determination, and each ratio was firstly made into 5 series of concentration gradients. The synergistic test was carried out for the 5 proportions according to the synergistic test method. Calculate the IC of 5 mixtures and 2 single doses 50 value, calculate the co-toxicity coefficient, and judge whether it has a synergistic effect. The judgment standard is that the co-toxicity coefficient is significantly greater than 120, indicating that there is a synergistic effect; if it is significantly lower than 80, and the toxicity of the mixed agent is much lower than the highest toxicity in a single agent, it indicates that there is antagonism; if it is close to 100, it indicates that there is synergy. and function. The obtained toxicity regression equation and co-t...

Embodiment 2

[0022] Example 2 40% cyprodinil · propiconazole suspension

[0023] Cyprodinil 25g, propiconazole 15g, phenylphenol polyoxyethyl ether phosphate 5g, ethylene glycol 5g, polycarboxylate 4g, xanthan gum 0.1g, magnesium aluminum silicate 0.8g, sodium benzoate 0.1 g. Water balance. The finished product of 40% cyprodinil-propiconazole suspension concentrate was made by conventional method. According to 1000-fold dilution, the control effect on banana leaf spot is 83.93%-87.35%, and the control effect on banana scab is over 80%. However, the 50% cyprodinil water dispersible granules and 30% propiconazole suspension diluted 1000 times have control effects on banana leaf spot disease after 7 days, which are 60.44%-65.72% and 52.63%-60.18%, respectively.

Embodiment 3

[0024] Example 3 30% cyprodinil·propiconazole microemulsion

[0025] Cyprodinil 17g, propiconazole 13g, calcium alkylbenzenesulfonate 5g, phenylphenol polyoxyethyl ether 5g, nonylphenol polyoxyethylene ether phosphate 5g, N-methylpyrrolidone 20g, propylene glycol 4g, 0.1 g of organosilicone and the rest of water are used to prepare a 30% cyprodinil-propiconazole microemulsion finished product according to a conventional method. The composition is diluted 1000 times to control wheat powdery mildew, and the control effect is 80.25%-88.95% 7 days after application. And 50% cyprodinil water-dispersible granules diluted 1000 times and 20% propiconazole microemulsion diluted 800 times were used to control wheat powdery mildew, and the control effects were 72.31-76.74% and 67.21%-72.85% respectively after 7 days.

Abstract

The invention relates to a composition having bactericidal function. The active components comprise cyprodinil and propiconazole, wherein the weight percentage of the cyprodinil and the propiconazole is 1:10 to 10:1. The bactericidal composition has obvious synergized function when the cyprodinil and the propiconazole are compounded, is used for preventing and curing leaf spot of banana, wheat powdery mildew and rice sheath blight disease, and especially has remarkable preventing and curing effect to the wheat powdery mildew.

Description

Technical field: [0001] The invention relates to a fungicide composition and its application, in particular to a fungicide composition with cyprodinil and propiconazole as main active ingredients. Background technique: [0002] Cyprodinil belongs to pyrimidine amine fungicides. It has protective and therapeutic effects. Its leaves penetrate and the roots have strong systemic properties. It can be used as foliar spray or seed treatment, and can also be used as barley seed coating medicine. The spray dose is 150~750g(a.i.) / hm 2， The seed treatment dose was 5g (a.i.) / 100kg seeds. It is mainly effective in preventing and treating anthracnose, gray mold, powdery mildew and scab of fruit trees and vegetables. [0003] Propiconazole, a systemic triazole fungicide with protective and therapeutic effects, can be absorbed by roots, stems, and leaves, and can quickly conduct upwards in plants. It is used to prevent and control diseases caused by ascomycetes, basidiomycetes and deute...
