Hands on Training Sessions featured at the Northeast Greenhouse Conference

Growers always value hands-on training sessions to learn the tools they need to be successful in today’s competitive environment.

Come participate in the following hands on training sessions:

Monitoring the Greenhouse Environment by Chris Currey from Iowa State University to be held on Thursday, November 10th from 9:00-9:50 am.

Come learn about some of the tools you can use to measure and monitor light and temperature to successfully grow your crops.

Monitoring Growing Media: pH and EC, by Rosa Raudales from University of Connecticut to be held on Thursday, November 10th from 10:30 to 11:20.

Come learn how to properly collect samples, how to measure pH and EC and how to interpret the results.

How to Get the Most from Your Beneficial Insects by Suzanne Wainwright –Evans, Buglady Consulting to be held on Thursday, November 10th from 1:30 to 2:20.

Get tips and recommendations on how to get the most out of your beneficial insects and mites so you have the most efficient program possible.

Monitoring for Insects

Brazil internsIt may not be the Olympics, but we’ve been busy with Brazil too. Last week, Leanne Pundt visited Geremia’s Greenhouses in Wallingford to help train their interns on how to identify and monitor for insects on their yellow sticky cards. The interns are all from Brazil and part of The Ohio Program, an International Exchange Program of The Ohio State University specializing in Internships for Horticulture, Agriculture and Turf Grass.

Yellow sticky cards are used in greenhouses to monitor for winged insect pests such as whiteflies, thrips, fungus gnats, aphids, shore flies, and leafminers and leafhoppers. Growers can look at trends and see if insect populations are increasing or decreasing to determine if they need to treat and how well their management strategies are working. For more see: Identifying Some Pest and Beneficial Insects on Your Sticky Cards

Interns were: Giovane Giorgetti, Thales Fogagnoli, and Paulo Boaretto (holding the reference book).

Biological Controls in Greenhouses

More Connecticut greenhouse growers and retailers are using biological controls to manage insect and diseases (Photo of greenhouse). Here you can see a variety of spring plants for sale that were grown using biological controls (beneficial insects and mites, and biologically based fungicides). As an  example, this yellow gerbera daisy flower was grown using biological controls. (yellow gerbera daisy). This is to prevent damage from western flower thrips that can damage flowers (pink gerbera daisy). Small predatory mites (photo of bags in plants) are placed in the crop that prey upon the small thrips in the flowers. Here the predatory mites  are contained inside a controlled release sachet containing bran and a additional food source for the beneficial mites. The small predatory mites emerge from these small paper sachets over a 4 to 6 week period preying upon western flower thrips. (Note: western flower thrips are primarily a concern in greenhouse production, not in the home garden). Source: Leanne Pundt, UConn Extension Educator in Greenhouse IPM.
