MaxCel® Plant Growth Regulator

Bigger Fruit for Bigger Profits


MaxCel® Plant Growth Regulator is a proven fruit thinning agent which increases fruit size and helps improve return bloom. It helps fruit reach its full potential – even difficult-to-size varieties such as Gala, Fuji and Empire apples, plus Bartlett and Bosc pears. Due to its growth promoting action, MaxCel increases fruit size beyond the direct thinning effect providing greater packout and fewer undersized fruit than traditional thinners.
