Thifensulfuron methyl is a kind of post-treatment herbicide with internal absorption and conduction. It has high selectivity between cereal crops and broad-leaved weeds. It can be used to control annual broad-leaved weeds in wheat and corn fields, such as Artemisia annua, Zoysia japonica, Zoysia japonica, shepherd’s purse, pig’s purse, wheat vine, Lithospermum arvense, Nestle, pig’s hair, wolf’s broom, Rumex, Chenopodium, Bidens bipinnata, cabbage Weasel petal flower, wheat blue vegetable, wild watermelon seedling, wild mustard, sheep’s hoof, 3-leaf former commelina communis, etc. It has a certain inhibitory effect on perennial grasses such as chicory, spinach, artichoke and Spiraea. The weeds were injured more than ten hours after receiving the medicine. Although they still remained green, they stopped growing. After 1-3 weeks, the leaves at the growth point began to turn green and yellow, and the surrounding leaves drooped. Then the growth point withered, the grass shrank, and finally the whole plant died. The growth of some undead grass plants is seriously inhibited, shrinking under wheat plants or corn plants, and it is difficult to blossom and bear fruit. Thifensulfuron methyl is highly selective and safe for wheat and corn. The agent is rapidly degraded into sugars in wheat without affecting the normal growth of wheat. Thifensulfuron methyl is rapidly decomposed by aerobic microorganisms in soil, and the residual effect period is only 30 days. Therefore, it has no impact on subsequent crops such as peanut, soybean, sesame, cotton, rice, vegetables and flowers after use in wheat field, which is safer than the use of bensulfuron methyl, Chlorsulfuron methyl and Metsulfuron methyl. The safe interval between pesticide application and subsequent crops is 60 days, and crops can be used at most once per season. It cannot be mixed with organophosphorus insecticides or used in sequence; Sandy soil, low injection land and high alkaline soil should not be used. Thifensulfuron methyl products include 10%, 15%, 25%, 30%, 70%, 75% wettable powder and 75% dry suspension.
When thifensulfuron methyl herbicide was applied, it was absorbed by plant leaves and roots and transmitted rapidly in the plant, so that the plant died within 1 ~ 3 weeks after receiving the drug, and had strong drug resistance to cereal crops.
Thifensulfuron methyl can decompose rapidly in soil and is harmless to the next crop after 30 days; Thifensulfuron methyl can be used in wheat, barley, corn and other crops to control broad-leaved weeds.
The weeds that Thifensulfuron methyl herbicide can control include amaranth, Portulaca oleracea, pig disaster, mother-in-law Na, Artemisia annua, Zoysia, shepherd’s purse, rehmannia, spring Polygonum, etc., but it has no effect on Convolvulus, Carex and gramineous weeds.
