Embodiment 1

[0081] Weigh 5% syringstrobin, 45% triadol, 4% Morwet D-425 (sodium salt of alkylnaphthalene sulfonic acid condensation polymer, produced by AkzoNobel), 3% diffusing agent NNO, 2% pull-off powder BX , 2% K-12, 3% cornstarch, 5% sucrose, and kaolin are added to 100% by weight. The above-mentioned raw materials are prepared through the conventional method for preparing water-dispersible granules, ie, mixing, ultra-micro airflow pulverization, mixing, and granulating steps to prepare 50% syringstrobin-triconazole water-dispersible granules.

[0082] The formula is used to prevent and control wheat sheath blight, the dosage per mu is 8g, diluted and sprayed with 50kg of water, and the control effect is 93.5% after 10 days of application. 20% syringstrobin suspending agent is 22.5g per mu and 50% triadol WP is 15g per mu. Using the same method, the control effects after 10 days of application are 75.2% and 85.6% respectively.

Embodiment 2

[0084] Weigh 60% syringstrobin, 20% metconazole, 3% TERSPERSE 2700, 3% diffusing agent NNO, 2% pull open powder BX, 2% K-12, 1% carboxymethylcellulose, 5% urea, Diatomaceous earth is added to 100% by weight. 80% syringstrobin-metconazole water-dispersible granules are prepared by the conventional method for preparing water-dispersible granules from the above-mentioned raw materials, ie, mixing, ultrafine airflow pulverization, mixing, and granulation.

[0085] The formula is used to prevent and control rice sheath blight, the dosage per mu is 5g, diluted and sprayed with 50kg of water, and the control effect is 92.3% after 10 days of application. The dosage of 20% syringstrobin suspending agent is 22.5g per mu and the dosage of 6% metconazole water emulsion is 50g per mu. Using the same method, the control effect after 10 days of application is 83.5% and 78.9% respectively.

Embodiment 3

[0087] Weigh 40% syringstrobin, 10% preconazole, 4% TERSPERSE 2700, 2% diffusing agent NNO, 2% opening powder BX, 2% K-12, 3% corn starch, 5% ammonium sulfate, attapulgite Soil is added to 100% by weight. 50% syringstrobin-conconazole water-dispersible granules are prepared by the conventional method for preparing water-dispersible granules from the above-mentioned raw materials, ie, mixing, ultrafine airflow pulverization, mixing, and granulation.

[0088] The formula is used to prevent and control wheat sheath blight, the dosage per mu is 8g, diluted and sprayed with 50kg of water, and the control effect is 94.5% after 10 days of application. The dosage of 20% syringstrobin suspending agent is 22.5g per mu and the dosage of 6% cloconazole suspending agent is 50g per mu. Using the same method, the control effect after 10 days of application is 81.8% and 77.3% respectively.

Abstract

The invention discloses an agricultural fungicidal composition containing syringstrobin and triazole fungicides and its application, comprising effective active ingredients selected from powders selected from the first active ingredient syringstrobin and the second active ingredient triazole fungicides A composition of conazole alcohol, metconazole and paconazole, the weight ratio of the first active ingredient to the second active ingredient is 1:30-30:1. The composition can be formulated into agriculturally acceptable water-dispersible granules, wettable powders, suspensions, dispersible oil suspensions, emulsifiable concentrates, microemulsions, suspended seed coatings, and paste formulations. The composition of the invention is reasonable, the bactericidal effect is good, and the cost of medication is low, and its activity and bactericidal effect are not a simple superposition of the activities of each component. Compared with the existing single preparation, it not only has a significant bactericidal effect, but also has a significant The synergistic effect of slowing down the generation of resistance, the residual amount of the preparation is small, no pollution to crops, good safety, and meets the safety requirements of pesticide preparations. The present invention is effective against apple tree rot, apple leaf spot, rice blast, Sheath blight, banana leaf spot, wheat sheath blight have significant control effect.

Description

[0001] The patent application of the present invention is a divisional application of the invention and creation name: a fungicidal composition containing syringstrobin and triazole fungicides, the application number is 201110205478.4, and the filing date is 2011-07-19. technical field [0002] The invention relates to an agricultural fungicide composition containing syringstrobin and triazole fungicides, and belongs to the technical field of compound pesticides. Background technique [0003] Methoxyacrylic fungicides are newly developed fungicide varieties in recent years and are a major milestone in the field of fungicides. Methoxyacrylate fungicides have a unique mechanism of action, which prevents ATP synthesis in cells by locking the electron transfer between cytochrome b and c1, thereby inhibiting mitochondrial respiration and exerting antibacterial effects. Effective against strains resistant to 14-demethylase inhibitors, benzamides, dicarboxamides and benzimidazoles....
