Agricultural weed killer propanil 36% EC amides selectivity contact herbicide, Crop Protection Weedicide

Chemical property

Pure products are white needle like crystals. M.p.92 ~ 93 C, vapor pressure 1.2 * 10-2Pa (60 C). The solubility was 54% ethanol, 60% dimethylformamide, 35% cyclohexanone, 25% methyl ethyl ketone, 3% toluene, 3% xylene and 225mg/L water. In acidic and alkaline media, 3,4- two chloraniline and propionic acid were

hydrolyzed. It is easy to decompose in soil, so it is not suitable for soil treatment. The product crystallized during storage. No corrosion to metals. The raw material is m.p.85 to 89 degrees Celsius.

Purpose

Amides are highly selective contact-killing herbicides, mainly used in seedling or direct-seeding fields, and are effective against barnyard grass. They can also be used to control many other grasses and dicotyledonous weeds, such as duck tongue grass, water celery, cattail grass, etc.

Propoxicin is almost not transported in plants but plays a role in the contact area. Its mechanism of action is multifaceted, not only destroys the photosynthesis of plants, but also inhibits respiration and oxygen phosphorylation, interferes with the synthesis of nucleic acid and protein. Thus the physiological function of sensitive plants is affected, accelerating water loss, leaf drying, and eventually death.

Dichlor barnyard grass (Echinochloa crusgalli L.) is rapidly decomposed into non-toxic substances by hydrolytic enzymes in rice, and its degradation ability is 20 times greater than that of Echinochloa crusgalli L. so it is safe for water show. Usually, the barnyard grass was sprayed with 20% EC 113-150mL/100m2 from the second leaf to the third leaf and 5.3kg water.

Dry water layer should be drained before spraying, dew should be dried the next day, and then be irrigated 24 hours apart, keeping normal drainage and irrigation after 2 days. The light intensity is strong and the effect is good. When the temperature is above 30, it is easy to cause phytotoxicity.
