Prudent® 40Plus

Phosphite Fertilizer + Amino Acids

Prudent® 40PLUS highly concentrated phosphite fertilizer (40% PO3, expressed as P2O5), is formulated with patented urea phosphite and Pennamin Driver-P amino acids. The amino acids aid in building tolerance against environmental stresses, help move nutrients into the plant, and, play important roles in almost every plant function. And, since they are free amino acids they are readily plant- available. This saved energy can then be used for other plant functions.

•  Economical and efficient, used at lower rates than common potassium phosphite fertilizers
•  PO3 stays stable in jug because of its low water content
•  Mixes easily in tank mixes since it is compatible with most fertilizers and pesticides
•  Increases the integrity of plant cell walls, which improves plant strength and resistance
•  Aids in the absorption and transportation of micronutrients
•  Increases chlorophyll synthesis and concentration for improved light energy absorption
•  Activates the synthesis of plant hormones and other organic compounds in the plant
•  Helps improve plant pollen fertility and increases pollen germination
•  Improves seedling growth and plant vigor
