Libertyville, Illinois (April 22, 2008)–Apple growers in Canada now have access to a state-of-the-art product for use in post-bloom thinning and sizing programs. MaxCel® plant growth regulator has received PMRA registration and will be available commercially in all provinces for the 2008 growing season.


As the primary component of a thinning/sizing program, MaxCel is an effective tool for reducing hand thinning costs, maximizing fruit size potential, and reducing alternate bearing, even on difficult-to-size varieties such as Gala, Fuji and Empire.

First introduced in 2003 by Valent BioSciences Corporation, MaxCel is now distributed globally in more than 10 countries around the world. In Canada, MaxCel will be marketed by Valent Canada, which is headquartered in Guelph, Ontario.

"We are excited about introducing MaxCel to help apple growers reach optimum value from their orchards," said Regina Rieckenburg, Valent Canada market manager. "We are dedicated to bringing new solutions to the Canadian apple industry and are pleased to introduce MaxCel in the 2008 growing season."

MaxCel contains a cytokinin-based plant growth regulator with a patent-pending formulation that offers optimal coverage and absorption into plant tissues. Unlike other chemical thinning agents, MaxCel promotes fruit growth beyond the thinning effect, resulting in increased fruit size and improved packout.

"Valent BioSciences Corporation is always trying to identify growers’ needs and develop innovative solutions to help them maximize their profits," added Johan Pienaar, global marketing manager for MaxCel. "This is why we developed MaxCel – to provide growers with a better solution for their thinning and sizing needs."

Other Valent BioSciences Corporation products available in Canada for apple growers include Promalin® plant growth regulator, Accel® plant growth regulator, ReTain® plant growth regulator and DiPel® biological insecticide.
