Occasional or prolonged high temperatures can cause different physiological and biochemical changes in the plants. These variations effect plant growth as well as development and reduced yield and quality. Use Si-Phi throughout the entire grow cycle to ensure plants thrive in all environments.
Nutrifield’s Si-Phi contains Phosphite (Phi) which stimulates the plants metabolism to promote robustness and stress resistance. Phosphite is emerging as a new molecule that can be used as a biostimulant to enhance plant performance especially in restricting environments.
