The problem of regulating the growth and development of plants with the help of physio-logically active substances that have both growth-regulating, anti-stress and immune-stimulating effects in the system of other elements of technology is one of the most pressing in modern biol-ogy, the realization of their biological resource and productive potential. Research has shown that the biostimulants used in the experiment, Isabion and Benefit, had different effects on the survival rate of seedlings of the studied tomato hybrid Semko 98, biometric indicators of plants, yield and quality of marketable fruits.
