Can't tell the difference between trichloropyroxyacetic acid and chlorofluoropyroxyacetic acid?
Trichloropyroxyacetic acid is an important formulation raw material for Lier Chemical Tuba herbicides. Tuba is a multifunctional compound herbicide with glyphosate as the core to kill malignant weeds. Among them, the content of glyphosate was 50.4%, the content of trichloropyroxyacetic acid was 19.6%, and the total content was 70%.
Trichloropyroxyacetic acid is also called cover shrubland, green grass, ethoxycarpine. It has a very good weed control effect on a variety of broad-leaved weeds, including broad-leaved shrubs. However, it is ineffective against grasses and sedges. For example, double spike finches barnyard, river dragon, dogtail grass, Matang white grass, incense stick, Yinglin and so on. #人人能科普, there is new knowledge everywhere#
Trichloropyroxyacetic acid has strong endository properties, and the agent can be absorbed by the rhizomes and leaves of weeds or shrubs, and conducted in the weeds or shrubs, causing deformity and metamorphosis of weeds, and the nutrients in the body are "exhausted" and die.
Tuba is mainly used for weeding in non-arable land, or for the exclusion of useless shrubs or shrubs at the edge of the garden. The targets of the competition are mainly swimming grass (crossing the river dragon), water celery, small flying canopy, water peanut, knotweed, bamboo leaf grass, cow tendon grass and other vicious weeds.
Chlorofluoropyroxyacetic acid is an important formula of "Tengjing", of which the content of chlorofluoropyoxyacetic acid is 8.5%, the content of 2-methyl-4 chloroisooctyl ester is 34%, and the total content is 42.5%. #Agricultural Technology Science Competition#
Tengjing is mainly used as a seedling selective herbicide for broad-leaved weeds such as rice field competition, bamboo leaf grass, rain long flower, pig nostrils (duck tongue grass), wild mushroom seedlings, and Ze diarrhea.
Of course, it can also be used for post-seedling weeding in corn plots, and both maize and rice are grass crops. #Sannong Squad#
Because chlorofluoropyoxyacetic acid is used to control broad-leaved weeds after seedlings, it is ineffective against grass weeds and is naturally safe for grass crops.
The control of weeds by chlorofluoropyoxyacetic acid is also a typical hormonal type of weed control, and the agent can be absorbed by the rhizomes and leaves of the weed and conducted in the weed body. The weeds after the drug damage are deformed. From this point of view, the drug damage of trichloropyroxyacetic acid to weeds is almost the same as that of chlorofluoropyrazoleacetic acid, and there is little difference.
