Bactericide agent composition containing tiadinil and flutolanil

Abstract

The invention relates to a disinfectant composition formed by using benthiavalicarb-isopropyl and propamocarb as main ingredients and adding addition agent as well as filler carriers. The composition has the advantages of special effects on preventing and curing the propamocarb disease for various crops, fruits and fruit trees, simple processing technique, no three wastes and convenient use.

Description

(1) Technical field [0001] The invention belongs to the field of pesticides and relates to a fungicide composition. (2) Background technology [0002] Sheath blight mainly survives the winter with sclerotia in the soil. In the second year, the sclerotia floating on the water germinates and extracts hyphae, which are immersed in the sheath to form lesion spots, and mycelium grows from the lesion spots and spreads to nearby to form new lesion spots. When the sclerotia falls into the water, it can be spread by water flow. The disease begins when the temperature is above 22°C and the relative humidity is 97%. The most suitable temperature for mycelium development and pathogenicity is 28°C, and 25-31°C and saturated humidity are favorable conditions for disease prevalence. Excessive use of nitrogen fertilizer, high density planting, too deep or delayed irrigation are the main factors that induce disease. The disease of rice starts from the tillering stage, reaches the peak arou...

Problems solved by technology

[0003] At present, the fungicides used to prevent and control sheath blight mainly use antibiotic pesticides, carbendazim, thiophanate and other pesticides, and the control effects are always unsatisfactory, such as 5% Jinggangmycin aqueous solution, 2...
