Process for producing 5 percent hexaconazole suspending agent

Abstract

The invention relates to a process for producing a 5 percent hexaconazole suspending agent. A formulation of the hexaconazole suspending agent comprises 50.3 kilograms per ton of hexaconazole, 120 kilograms per ton of special assistant, 3 kilograms per ton of xanthan gum, kilograms per ton of DMF and proper amount of water. The hexaconazole suspending agent has a good effect of preventing and controlling rice sheath blight; the hexaconazole suspending agent is applied at the attack initial period of the rice sheath blight, preferably 80 to 100 milliliters in each mu; the hexaconazole suspending agent is evenly sprayed to rice strains, the prevention effect reaches more than 80 percent, and the environment pollution is lightened; and the hexaconazole suspending agent has good effects of preventing and controlling powdery mildew and gray mold of economical plants, such as grape and the like, beside preventing and controlling fungal diseases of grain crops.

Description

Technical field: [0001] The invention relates to a production process of 5% hexaconazole suspension concentrate. Background technique: [0002] Rice sheath blight is one of the main diseases of rice crops, which occurs every year, especially under the condition of suitable temperature, the spread of the disease is more serious, affecting the growth of crops and reducing the yield. Due to the increase in resistance of some old pesticides (emulsifiable concentrates and powders) commonly used in my country for this disease for many years, the use effect has obviously declined, and the environmental pollution is serious. [0003] Hexaconazole is a sterol demethylation inhibitor, which destroys and prevents the biosynthesis of ergosterol, an important component of the cell membrane of bacteria, resulting in the inability of the cell membrane to form and the death of the bacteria. Has systemic, protective and therapeutic activity. It is suitable for fruit trees such as apples, g...

Problems solved by technology

[0004] At present, a series of hexaconazole products have been developed and produced, and the insecticidal effect is remarkable, but the therapeutic effect on rice sheath blight is not very outstanding
