How does Capreno work?
Capreno uses two sites of action that BOTH effectively control the toughest grass and broadleaf weeds. The first mode of action, commonly known as a bleacher, inhibits the 4-hydroxyphenylpyruvate dioxygenase (HPPD) enzyme in plants. HPPD is key to the production of a plant's protective pigments. By preventing pigment production, plant chlorophyll is destroyed by the sun's ultraviolet rays. The second mode of action is the inhibition of the plant's acetolactate synthase enzyme that prevents weeds from producing three essential branch-chain amino acids. These amino acids are building blocks for normal growth and development that weeds need to survive.
