Bensulfuron-methyl belongs to the sulfonylurea class of broad-spectrum, high-efficiency, low-toxic herbicides for paddy fields. It has ultra-high-efficiency activity. At the time of initial registration, the dosage of 1.3-2.5 g per 666.7 M2 can control various annual and perennial broad-leaved weeds and sedges in rice fields, and it also has inhibitory effects on barnyard grass. 1. Chemical properties The pure product is a white odorless solid, stable in slightly alkaline (pH = 8) aqueous solution, and decomposes slowly in acidic solution. The half-life is 11 d at pH 5 and 143 d at pH 7. The original drug is A little light yellow. 2. Mechanism of action Bensulfuron-methyl is a selective systemic herbicide.
The active ingredients can diffuse Country Email List rapidly in water, absorbed by the roots and leaves of weeds and transfer to all parts of weeds, hinder the biosynthesis of amino acids and prevent cell division and growth. The growth function Sensitive weeds are disturbed, and premature yellowing of young tissues inhibits the growth of leaves, hinders the growth of roots and causes necrosis. The active ingredients enter the rice body and quickly metabolize into harmless inert chemicals, which are safe for rice .The method of use is flexible, and methods such as poisonous soil, poisonous sand, spray, and pouring can be used.
It has little mobility in the soil, and the influence of temperature and soil quality on its weeding effect is small. 3. Action goal Benzulfuron-methyl is an epically produced paddy herbicide: 333 444 wide adaptability, It is suitable for paddy fields under different climates, different geographical environments and different cultivation systems. low dosage, The amount of application per hectare is reduced from the kilo level of traditional herbicides to the unit of grams. Herbicidal spectrum broad, It has an excellent control effect on annual and perennial broadgrass and sedge, especially on knotweed and cattle fur, and has a strong growth inhibitory effect on barnyardgrass and other grasses in high doses. Long application time, Can be applied before and after seedlings high security, Not only is it safe for the current crop of rice, it has no adverse effect on the growth of rice, no soil residue, and it is also very safe for subsequent crops.
