Crop Protection
Is 2006 shaping up to be… the year of the thrips? The mild winter may have allowed outdoor thrips populations to survive more successfully than in previous years.
An overview of Ontario’s greenhouse vegetable industry.  Among continuing trends, glass and hot water heating are popular with new construction.
Managing resistance in cabbage loopers. 
Thrips accounts for more than 25 per cent of insect pest management costs in Ontario’s floriculture industry. WFT is especially difficult and expensive to control because many of its life stages are hidden in the plant foliage.

The reasons why it’s difficult to freeze out pests in greenhouses.  We are at that time of year when many greenhouse vegetable growers are thinking of cleaning up for the spring crop.
DNA – a new tool for insect identification.  This technology should prove to be a valuable aid to taxonomists and will be a major resource for plant exporters.
Watch out for those late-season glitches.  In the previous couple of issues, I have discussed many of the important cultural aspects of which we as growers need to be mindful when establishing and growing-on quality poinsettias.
Botrytis … ’tis the season!  Growers need to implement strategies to ward off this ever-present fungus
An ounce of prevention is indeed worth a pound of cure!  You can pay now, or pay (much, much more!) later
Holiday season tradition continues at Vineland.  Annual open house offers ‘one-stop-shopping’ in viewing
new poinsettia varieties
Early release of predators can help combat diseases.  Two proven performers are Hypoaspis miles and the rove beetle (Atheta coriaria).
Dealing with the Japanese Beetle: what are a grower’s obligations? This beetle has a varied appetite, feeding on more than 300 different plant species, including many important ornamentals.
“I find it fascinating how many solid arguments could be made that would speak strongly in favour of the safe use of pesticides, once we learn about the chemistry, the biology, and the history of chemical pest control. It also fascinates me that we hear so few of these arguments in public discourse.”

“A Japanese Beetle Management Plan is a document that lists how the greenhouse facility will meet all the criteria necessary for the certification program applied for. It may seem like a lot of work, but when looked at closely, it can be done fairly quickly.”

Biological control of whitefly in poinsettia – can trap plants help?  Research on this pest management tool in greenhouse production is expanding
