Microorganisms or chemicals derived from synthetic or natural ingredients are known as biostimulants. They are combined with substrates and added to plants, soil, or seeds to encourage organic growth and strengthen plant defences. Additionally, they provide crop protection and aid in plant nutrient absorption.In contrast to biopesticides and biofertilizers, Biostimulants are crop stimulants. Biostimulants, which are used to address nutrient deficiencies and protect plants, are a mixture of microbes, plant hormones, enzymes, marine woods, and trace elements. Biostimulants provide complementary functions for crop nutrition and crop protection by promoting plant growth and development across the entire agricultural life cycle, from seed germination through plant maturity.
They improve plant nutrient absorption, antioxidant activity, and stress tolerance to drought, floods, severe temperatures, and salinity. As a viable substitute for chemical-based products, they are also more affordable, produce better crop yields, and are less harmful to the environment. For a variety of plants, including cereals and pulses, fruits and vegetables, turf and ornamentals, and oilseeds and pulses, biostimulants are utilised. Biostimulants have gained popularity as a result of their crucial function in environmentally friendly farming methods. Global adoption of eco-friendly products and rising awareness of the benefits of using biostimulants are driving the expansion of the latter. Lack of arable land for agriculture and the increased demand for high-value crops are two major factors driving up the price of biostimulants.
