Аннотация:The plant growth regulator floroxan, 2-hydroxy-3,3,3-trifluoromethyl-2-(4-methylamino-phenyl)-propionic acid ethyl ester hydrochloride, is a development of INEOS RAS and has been studied for many years. To improve the physicochemical properties of floroxan, studies were carried out to develop forms of its application. Floroxan, having high efficiency at a dosage of 100 mg/l, has great prospects for use as a component in the compositions of known preparations for pre-sowing treatment of seeds of cultivated plants. Conducted in recent years, joint research with scientists from Russia and Uzbekistan has made it possible to develop and offer for agriculture such promising preparations as seed dressing agents, herbicide antidotes, compositions for use on cotton and a number of vegetable crops.
