Action characteristics: Nicosulfuron methyl is an internally absorbed and conductive herbicide, which can be absorbed and rapidly transmitted by the stems, leaves and roots of plants. Through the activity of acetyllactate synthase in plants, Nicosulfuron methyl prevents the synthesis of branched chain amino acids such as glycine, leucine and isoleucine, thus preventing cell division and stopping the growth of sensitive plants. The symptoms of weed damage were yellowing, chlorosis and albinism of heart leaves, and then yellowing of other leaves from top to bottom. Generally, the symptoms of weed damage can be seen 3 ~ 4 days after application, the annual weeds die in 1 ~ 3 weeks, and the perennial broad-leaved weeds below 6 leaves are affected, stop growing and lose their competitiveness with corn. High dose can also kill perennial weeds.
Control objects: barnyardgrass, horse Tang, beef tendon grass, Dogtail grass, amaranth, Portulaca oleracea, jute, Convolvulus convolvulata, prickly thorn, endive, golden dog tail grass, wild millet, Solanum nigrum, Elsholtzia, Xanthium sibiricum, Commelina communis, wind flower, repressor blue cabbage, Vitex, Artemisia, artichoke, wild oats and other annual weeds and perennial broad-leaved weeds.
Nicosulfuron is a sulfonylurea herbicide that inhibits plant acetyllactate synthase (branched chain amino acid synthesis inhibitor). It can be used to control annual and perennial gramineous weeds, sedges and some broad-leaved weeds in corn field. It is more active against narrow leaf weeds than broad-leaved weeds and safe for corn crops. It is used in rice seedling field, Honda and direct seeding field to control annual and perennial broad-leaved weeds and Cyperaceae weeds, and also has a certain inhibitory effect on barnyardgrass.
