Aug. 16, 2011, Peoria, IL — U.S. Department of Agriculture (USDA) scientists are investigating the pest-fighting potential of anthocyanins, healthful chemical compounds in the form of plant pigments that give blueberries, plums, grapes and flowers such as petunias their blue and purple colour.

A significant labour savings potential from a most unlikely source is among the latest buzz from the Greenhouse and Processing Crops Research Centre in Harrow, Ontario.
Though many biocontrol programs for western flower thrips (WFT) in greenhouse vegetables are successful, this pest is often a challenge to manage, particularly when incidence begins early in the season. Part of the challenge lies in the lack of pesticide options that can quickly suppress populations while allowing biocontrol agents to establish a favourable predator/pest ratio. Despite this, many growers are able to successfully manage WFT populations by adhering to two key management recommendations as follows:
Effective and environmentally sound pest management programs do not happen by chance
New” crop pests and diseases regularly cause concern to greenhouse growers.
Clean cuttings, young plants or plugs… this has been a discussion point for many years in our industry.
OMAFRA’s Grower Notes was published as a hard copy newsletter mailed to Ontario growers from the 1980s through until March 1997.
Feb. 21, 2011, Ames, Iowa – Becker Underwood, Inc. has launched its new beneficial nematodes blog, Nematode News.
Broad mites, or Polyphagotarsonemus latus, can be a serious pest of greenhouse peppers and a wide range of greenhouse ornamental plants including: gerbera, African violet, cyclamen, begonias, impatiens, verbena and gloxinia.
What impact will climate change have on biological control communities?
That’s the question Jessica Sparkes, a Master’s student at the University of Windsor, is helping tackle with her research project at the Greenhouse and Processing Crops Research Centre at Harrow, Ont.
The reasons for using biological pest control are numerous and include, (a) the absence of a re-entry interval (REI) or pre-harvest interval (PHI), (b) no requirement for an applicator licence, (c) no phytotoxicity to the crop, and, of course, (d) it is part of sustainable or “green” growing.
Biological control is increasingly being successfully used by growers to manage pests and diseases in greenhouse floriculture crops.
April 22, 2010, London, England – Bees see the world almost five times faster than humans, according to new research from scientists at Queen Mary, University of London.
