fluroxypyr-methyl 288g/L EC Agricultural Herbicides, Organic heterocyclic herbicides
Fluroxypyr is a synthetic compound of the pyridine family that acts as a synthetic auxin, one of the natural plant growth regulators. Fluroxypyr is used as a selective herbicide for the control of broad-leaved weeds, especially cleavers (Galium aparine).,polygonum convolvulus, Portulaca oleracea, Solanum nigrum, Stellaria media.
Convolvulus arvensis ect.Fluroxypyr is absorbed after foliar application and is translocated to other parts of the plant, therefore making it systemic in its action. The compound causes typical auxin-type responses in its target plants, such as leaf rolling. Fluroxypyr is on cereals, fallow land and on-farm non-cropland. Approved crops include barley (spring and winter), durum wheat, wheat (spring and winter)grassland and grass ley, oats (winter and spring), triticale and rye.
Fluroxypyr is often sold premixed with other active substances, such as clopyralid, florasulam, triclopyr, metsulfuron-methyl, MCPA and aminopyralid.

The half-lives of hydrolysis reaction were 9.8 D (pH = 5), 17.5 D (pH = 7) and 10.2 D (pH = 9).
Pyridoxy acetic acid herbicides. It has the function of internal absorption and has typical reaction of hormone type herbicides. After the use of seedlings, sensitive crops showed the reaction of typical hormone herbicides. It is suitable for use in cereal crops. It can be used to control broad-leaved weeds in wheat, barley, corn, grape and orchard, pasture and forest farm, such as Herba uni *, field, flowers, shepherd's purse, stemming, amaranth and purslane. If it is used in winter wheat, it will be used in the post-winter green period, spring wheat in the 2-4 leaf period, weeds are basically out of line after the application of medicine, with 50% EC 7.5-10 mL/100 m2, water 4.5 kg, in the weed 2-4 leaf period. It can also be mixed with many other herbicides such as 2,4-drop, 2-methyl-4-chloro, isopron, chlorotoluron, Hecaoling and Caojing.
