Fosamine Ammonium pgr plant growth Regulator CAS 25954-13-6

Physical and chemical properties

The pure product is white crystal, slightly peppermint flavor, melting point 175℃, easy to dissolve in water, slightly soluble in methanol and ethanol, and difficult to dissolve in chloroform, acetone, benzene, etc. It is easy to decompose under acidic conditions.

Functional features

Fosamine Ammonium is mainly absorbed by stems and leaves, and the specific effect is closely related to its concentration. 

At low concentration, it can inhibit the activities of peroxidase and indoleacetic acid oxidase, reduce the degradation of auxin, increase the accumulation of auxin, promote crop growth, improve fruit setting rate and increase yield. 

At higher concentrations, it can promote the activities of peroxidase and indoleacetic acid oxidase, accelerate the decomposition of auxin, inhibit the growth of plants, and have the effects of Dwarfing and pruning; 

At higher concentrations, it can inhibit the photosynthetic phosphorylation in the process of plant photosynthetic reaction, prevent the formation of bioenergy, and thus cause crop death. 

1.It can be used as a herbicide. 

2.It can prevent miscellaneous shrubs and twining plants (Convolvulaceae) in the forest. In addition, regulating phosphine can inhibit the biosynthesis of endogenous ethylene in plants and prevent premature senescence of branches and leaves. 

3.It is often used for fresh-keeping of cut flowers.

Precautions

①When adjusting phosphine as a regulator, the concentration should be strictly controlled to prevent drug damage.

②When using, spray the liquid from the top of the plant to the bottom. The dosage and time of application depend on the object and environment of application

③It should not be used within 20 days before the plant leaves to avoid prolonging the dormancy period of the plant.

④The fruit trees can only be sprayed with regulated phosphine for 2 years, and other regulators should be used in the third year to avoid affecting the growth of trees.

⑤Regulated phosphine can not be mixed with acid pesticides, but can be mixed with glyphosate, which can expａnd the herbicidal spectrum, have a lasting effect, reduce costs, and be safe to the environment. If a small amount of plastic element and bijiu are added to the mixture, the efficacy can be improved.
