Embodiment 1

[0018] A preparation method of a fungicide composition containing boscalid and flusilazole, comprising the following steps:

[0019] (1) The former drug of boscalid with a mass concentration of 85% and the former drug of flusilazole with a mass concentration of 80% were respectively made into 1 × 10 4 mg / L mother solution, stored at 4°C for later use.

[0020] (2) Use 0.1% Tween 20 to prepare the above-mentioned boscalid mother liquor into a medicinal solution containing 400 mg / L of boscalid, and use 0.1% Tween 20 to prepare the above-mentioned flusilazole mother liquor into a fluorosilazole 80mg / L liquid medicine.

[0021] (3) Mix equal volumes of the above-mentioned boscalid and flusilazole medicinal solutions, and prepare a composition containing 200 mg / L of boscalid and 40 mg / L of flusilazole.

Embodiment 2

[0023] A preparation method of a fungicide composition containing boscalid and flusilazole, comprising the following steps:

[0024] (1) The former drug of boscalid with a mass concentration of 85% and the former drug of flusilazole with a mass concentration of 80% were respectively made into 1 × 10 4 mg / L mother solution, stored at 4°C for later use.

[0025] (2) Use 0.1% Tween 20 to prepare the above-mentioned boscalid mother solution into a liquid containing 100 mg / L of boscalid, and use 0.1% Tween 20 to prepare the above-mentioned flusilazole mother solution into a fluorine-containing silazole 200mg / L liquid medicine.

[0026] (3) Mix equal volumes of the above-mentioned boscalid and flusilazole medicinal solutions, and prepare a composition containing 50 mg / L of boscalid and 100 mg / L of flusilazole.

Embodiment 3

[0028] A preparation method of a fungicide composition containing boscalid and flusilazole, comprising the following steps:

[0029] (1) The former drug of boscalid with a mass concentration of 85% and the former drug of flusilazole with a mass concentration of 80% were respectively made into 1 × 10 4 mg / L mother solution, stored at 4°C for later use.

[0030] (2) Use 0.1% Tween 20 to prepare the above-mentioned boscalid mother liquor into a medicinal solution containing 300 mg / L of boscalid, and use 0.1% Tween 20 to prepare the above-mentioned flusilazole mother liquor into fluorosilazole 150mg / L liquid medicine.

[0031] (3) Mix equal volumes of the above-mentioned boscalid and flusilazole drug solutions, and prepare a composition containing 150 mg / L of boscalid and 75 mg / L of flusilazole.

Abstract

The invention discloses a boscalid and fluorosilazole containing bactericide composition and a preparation method and the application thereof. The preparation method comprises the following steps: respectively preparing raw boscalid with the mass concentration of 85% and raw fluorosiliconazole with the mass concentration of 80% into 1*10<4>mg / L of mother solutions by using methanol, and storing atthe low temperature of 4 DEG C; preparing the boscalid mother solution into a pesticide solution containing 100-400mg / L of the boscalid by using Tween 20 with the concentration of 0.1%, and preparingthe fluorosilazole mother solution into a pesticide solution containing 80-200mg / L of the fluorosilazole by using the Tween 20 with the concentration of 0.1%; mixing the boscalid solution and the fluorosilazole solution according to an equal volume to obtain the composition containing 50-200mg / L of the boscalid and 40-100 mg / L of the flusilazole. The bactericide composition can control mildewed rot of tobacco leaves in a curing period, reduce the bactericide using cost and reduce pollutions to the environment.

Description

technical field [0001] The present invention relates to the field of biotechnology, in particular to a fungicide composition containing boscalid and flusilazole, and also to a method for preparing the fungicide composition containing boscalid and flusilazole, And the use of the fungicide composition containing boscalid and flusilazole to prevent and control tobacco leaf mold rot during the curing period. Background technique [0002] Tobaccopole rot, caused by Rhizopus oryzae Went et Pr.Geerl., is a fungal disease that easily occurs during the curing period of tobacco. It mainly occurs during the yellowing stage of tobacco leaves, and white hyphae usually appear at the base of the stem , quickly produce black spores and further spread the damage. In the process of tobacco leaf curing in intensive curing barns, the space is small, the temperature is high, the humidity is high, and the air flow is fast, which is conducive to the occurrence and prevalence of the disease. The ...
