This is the third article of the four article series highlighting the production and use of pine wood chips as aggregates in greenhouse substrates. We found growers do not need to adjust their production practices when 20% pine wood chips are utilized as a perlite replacement.

Syngenta’s launch of Bioline Biological Control Agents with its crop protection products and as part of an Integrated Crop Management program last year has paved the way for integrated pest control on all fronts.

Try out these four tips from growers who have successfully implemented biocontrol programs in their greenhouses.

In some greenhouses, western flower thrips are becoming more difficult to control due to high levels of resistance to some insecticides. Be sure to always rotate the modes of action of pesticides.

Biopesticides generally pose fewer risks than their chemical counterparts , making them a viable alternative for conventional and organic programs.

Bachman’s, a wholesale nursery and retail business based in Minnesota, has taken measures to address the steady decline of bees and other pollinators, including eliminating the use of neonicotinoids in some of its own production.

After two and a half years of research and trials, Jiffy has introduced The Preforma Orchid Plug. The propagation system is a six step concept developed by Jiffy to assist orchid growers in growing orchid young plants.

U.S. beekeepers lost more than a fifth of honey bee colonies this past winter — fewer than the winter before. Research shows there are fewer losses among beekeepers who carefully treat their hives to control a lethal parasite called the Varroa mite.

To demonstrate good environmental stewardship, growers need an understanding of the issues presenting risks to bees and of strategies to minimize the risks. Knowing where to find key product information and how to interpret it can help growers make sound choices regarding the application of effective products.

This is the second article of the four article series highlighting the production and use of pine wood chips as aggregates in greenhouse substrates.

Dr. Joe Bischoff, AmericanHort’s director of regulatory and legislative affairs, says it is important that we are informed and prepared to talk about the issue of pesticides, pollinators and the overarching concerns of bee health in a calm and clear manner. This is a topic where emotions can run high, and part of our role should be in explaining the need for balance and scientifically based solutions.

Cornell University researchers look at the impact cultural factors such as substrate amendments and substrate water-holding capacity have on fungus gnat populations.

A journey just over the United States’ border led Cascade Cuts of Bellingham, Wash., to begin using biocontrols. Alison Kutz, owner of Cascade Cuts greenhouses, explains the challenges and opportunities brought about with biocontrol implementation.
