Embodiment 1

[0036] The preparation method of 32% flufenadil·fludioxonil suspension seed coating agent: by mass percentage.

[0037]

[0038]Preparation method: According to the formula, weigh the above components in proportion, put into a ball mill and mill for 60 minutes, filter, pump into the dispersion tank for 3 minutes at high speed and then fully grind with a sand mill to control the particle diameter of the solid component within 2 microns , and stir evenly after grinding to obtain the suspension seed coating product. According to every 100kg of seeds, 300ml of suspended seed coating agent is used for chemical seed dressing, and is used for preventing and treating rhizoctonia solani and wheat sheath blight, and the control effects reach 88.6% and 81.5% respectively.

Embodiment 2

[0040] The preparation method of 22% flufenadil·fludioxonil suspension seed coating agent: by mass percentage.

[0041]

[0042] Preparation method, with embodiment 1. According to every 100kg of seeds, 300ml of suspended seed coating agent is used for chemical seed dressing to prevent and control rhizoctonia solani and wheat sheath blight, and the control effects reach 85.8% and 83.7% respectively.

Embodiment 3

[0044] The preparation method of 40% flufenadil·fludioxonil suspension seed coating agent: by mass percentage.

[0045]

[0046]

[0047] Preparation method, with embodiment 1. According to every 100kg of seeds, 200ml of the suspension seed coating agent is used for chemical seed dressing, and is used for preventing and treating rhizoctonia solani and wheat sheath blight, and the control effects reach 91.5% and 88.7% respectively.

Abstract

The invention discloses a penflufen and fludioxonil containing bactericidal composition and application thereof. The penflufen and fludioxonil containing bactericidal composition is prepared from effective ingredients containing penflufen and fludioxonil; proper amount of agricultural bactericide additives are added. The bactericidal composition has a good effect on treating fungi diseases of crops; the two preparations have obvious synergistic effects; the quantity of used bactericidal composition can be decreased, so that the ecological damage and environmental pollution can be effectively reduced, and the crops output and quality can be improved; penflufen and fludioxonil are small in toxicity and safe to human, livestock, beneficial organisms and environment; the bactericidal composition can delay the drug resistance of germs to single preparation.

Description

technical field [0001] The invention belongs to the field of agricultural fungicides, and in particular relates to a fungicidal composition of flufenadil and fludioxonil and an application thereof. Background technique [0002] Rhizoctonia solani (Rhizoctonia solani) is one of the most important pathogenic fungi that cause major crop diseases in the world. Rhizoctonia solani spreads through soil and can infect more than 27 families of plants, including many important food crops such as Plants such as rice, wheat, soybean, corn, etc., as well as various vegetables and flowers, are particularly harmful at the seedling stage of crops, causing lack of seedlings and breaking ridges, affecting crop yields. During the cultivation of Rhizoctonia solani, the same vegetative mycelia showed great morphological differences and differentiations under different conditions, indicating that the vegetative mycelia exhibited a huge variety in the process of asexual reproduction.
