Uses: Biochemical studies herbicides, plant growth agents, organic trace analysis Determination of carbon and hydrogen 24-D is a representative synthetic auxin (auxin) is displayed in normal plant growth hormone quantitative method has high activity, but in the use of plant growth hormone standard quantitative method oats elongation tests, its effect is quite low. When using chromotropic acid (chromotropic acid) treatment was purple, can be used for colorimetric quantification. This material is large-scale use herbicide and prevent early fruit shedding agent, thrown into the soil can be decomposed by gram-negative bacteria and aquatic Flavobacterium (Flavobacteriumaquatile) and other bacteria.
