RIPENING INDUCERS

POLIFILL PK ALPHA 21-27

PROMOTES A UNIFORM RIPENING
INCREASES BRIX AND IMPROVES FRUIT COLORING
FAVORS THE PLANT'S LIGNIFICATION PROCESSES

POLIFILL PK ALPHA 21-27 is a nutritional solution containing potassium, phosphorus and chelated microelements, to be applied as foliar applications. It stimulates the fruits' enlargement and creates the perfect conditions for the enhancement of their organoleptic properties (color, taste, aroma). By slowing down the main biochemical mechanism that causes vegetative vigour, POLIFILL PK ALPHA 21-27 favors the lignification process and prepares the plant for its winter rest.
