| overview | fluorobenzene substances have stable chemical properties, are difficult to biodegrade, and have carcinogenic and teratogenic effects on human body. mineralization and degradation of such substances have always been difficult problems in sewage treatment. P-fluorophenoxyacetic acid is an important phenoxy plant growth regulator, which can be absorbed through plant roots, stems, leaves, flowers and fruits. It is mainly used to prevent falling flowers and fruits, inhibit the rooting of beans, and promote fruit setting. It induces seedless fruits and has the effect of accelerating ripening and increasing yield. This kind of organic matter is one of the more common organic pollutants in agricultural production. |
| application | p-fluorophenoxyacetic acid can activate the resistance of rice to rice planthoppers, and can reduce the survival rate of rice planthoppers to below 10% at the highest, with high economic benefits. |
| Biological activity | 4-Fluorophenoxyacetic acid (4FPA) can induce parthenocarpy. 4-Fluorophenoxyacetic acid (4FPA) protects grains from fluke worms and thus increases rice yield in the field. |
| use | is a broad-spectrum plant growth regulator |
