PD No. PD20220096 Sulfentrazone 95% Tech Herbicide for Optimal Weed Elimination

Product Description 

Sulfentrazone is a member of the class of triazoles that is 5-oxo-1,2,4-triazole which is substituted at positions 1, 3, and 4 by 2,4-dichloro-5-[(methylsulfonyl) amino]phenyl, methyl, and difluoromethyl groups, respectively. A protoporphyrinogen oxidase inhibitor, it is used as a herbicide to control broad-leaved weeds in soya and tobacco crops.

Mode of Action

For Sulfentrazone

By inhibiting the process of chlorophyll biosynthesis, protoporphyrinogen oxidase causes cell membrane damage, leading to rapid leaf drying and death.

When 14C-sulfentrazone is applied to coffee senna and sicklepod through the roots, 83% of the parent compound remains in coffee senna leaf tissue after

9 h exposure and in contrast, sicklepod takes up relatively less sulfentrazone through the root and metabolizes sulfentrazone in the foliage more rapidly than coffee senna. The primary detoxification reaction appears to be oxidation of the methyl group on the triazolinone ring, resulting in the formation of the more polar hydroxymethyl derivative. The aniline analog is identified as a plant-specific metabolite. The tolerance of sicklepod to sulfentrazone is primarily due to a relatively high rate of metabolism of sulfentrazone compared with coffee senna. When 14C-sulfentrazone is administered orally to rats, goats, and hens in a daily diet, administered radioactivity is quantitatively excreted in the urine, feces, or hen excreta. In all of the species, unchanged sulfentrazone and two non-conjugated metabolites are found, which are 3-hydroxymethyl and carboxylic acid derivatives, the latter of which decomposes at high temperature or acidic pH to give the corresponding analog of sulfentrazone. In rats, a minor reduction metabolite is detected which is tentatively characterized as the 2,3-dihydro-3-hydroxymethyl derivative.

Use

Sulfentrazone is an herbicide used for controlling sedges in turfgrass.

Suitable for pre seedling or pre transplant treatment, to prevent and control annual broad-leaved weeds, some grass weeds, and sedges on crops such as soybeans, sugarcane, and 

tobacco, such as morning glory, anti branch amaranth, pig weed, ground skin, quinoa, mandala, 

horse Tang, dog tail grass, Xanthium sibiricum, cowweed, and Cyperus orientalis. It is safe for the next crop, but it has certain drug damage to cotton and sugar beets.

Sulfentrazone is an excellent soil treatment agent before sowing and stem and leaf treatment 

agent after seedling. It can be applied to fields such as peanuts, sugarcane, cassava, etc. 

Compared with other herbicides widely used in the market, it has better sealing effect and longer shelf life. It has ideal control effects on malignant weeds such as cowweed, barnyard grass, aconite,and fish yellow grass.
