Canadian growers can now use Asperello T34 Biocontrol on greenhouse cucumbers, tomatoes, peppers, strawberries, leafy greens and indoor cannabis for suppression or partial suppression of FusariumPythium and Phytophthora.

The Pest Management Regulatory Association (PMRA) of Canada approved the label expansion for theTrichoderma asperellum-based product this year. Approved applications include dips, soil incorporation, chemigation and drenches. In cucurbits it can also be applied through foliar application against Didymella.

Previously, Asperello was only approved for use in greenhouse ornamentals in Canada.

According to Biobest, the product can be applied preventatively by growers to colonize the roots of the crop, limiting space and nutrients for detrimental soilborne fungi. The company says Asperello works by triggering the plant’s natural defense mechanisms, parasitizes and actively kills pathogens, and supports healthy root growth.

“It has been a long wait for us and our growers.

Finally, the wait is over!” Says Veronica Cervantes, Product Manager of Biopesticides at Biobest North America.

“We take pride in bringing quality and reliable products to market, so growers have user friendly tools to solve their problems. In recent years Biobest has set focus on expanding its Biopesticide portfolio,” says Sarah van Beneden, Global Business Development Manager of Biopesticides at Belgium headquarters, “so we will continue to bring innovative solutions to the horticultural industry.”
