Biostimulant is an unregulated umbrella term for products that stimulate natural processes to enhance/benefit nutrient uptake, nutrient efficiency, tolerance to stress, crop quality and ultimately increase yield potential. The ultimate goal is always yield. Biostimulants can increase yield by keeping the crop at a “steady state” allowing photosynthesis and respiration to be performed at an optimum level even when the plant is under stress.
Hormone Based Biostimulants
Hormones are chemical messengers that modulate growth process in the plant. They work at very low concentrations as a “promote or impede” signal for plant metabolism. There are 5 major categories of plant hormones: Auxins, Cytokinins, Giberellin, Abscisic Acid and Ethylene. Small concentrations of hormones can have major effects on plant growth.
Hormone based products must be at the RIGHT RATIO AND CONCENTRATION to stimulate maximum growth. Different hormone concentrations and ratios can significantly impact the performance of the product applied. When the ratio and concentration is ideal, the use of hormone-based biostimulants will ultimately increase yield potential.
