Growth Stimulants: Plant Growth Regulators (PGRs) or plant growth stimulants are molecules that influence the development of plants and are generally active at very low concentrations. Plant growth and nutrition substances have a key role in different physiological processes related to development of crops. Changes in the levels of plant hormones and nutrients due to stress can adversely affect crop growth. Alfalite is a plant growth regulator auxin, contains Alpha Naphthyl Acetic Acid 4.5% SL.
