Greenhouse IPM update 3.10.17

Snow again!  And since they removed the Cornus mas from outside my window, I don’t have that friendly reminder of swelling buds to tell me spring is coming.  But it is, I know it IS!

Check those fertilizer injectors!  Who wants to find out they aren’t working by having plants show symptoms – and then trying to figure out why!  Thomas Ford in eGro says from his work “75% of the fertilizer injectors employed by growers in are greenhouses are not working properly”. We’ve already heard of one case in NY. Lots of information here.

Get the key to locking out pests (my, that’s kind of a stretch but it is Friday).  Leeane Pundt at UConn has a great post on key plants and key pests to help you inspect new plant material coming in and scouting it once it’s in your greenhouse.

Another on scouting guidelines and biocontrol options for the most common insects and diseases found in greenhouse crops.

And since a picture is worth a thousand words…illustrated scouting tips for lots of crops

Using biofungicides, biostimulants, and biofertilizers to boost crop productivity and help manage vegetable diseases – not just greenhouse but perhaps still useful!

Bees are still in the news!  One study from England I read said that most varieties surveyed in garden centers were unattractive to pollinators (actually measuring the number of visits by pollinators at the garden center itself).  While still low, those with some notation as being friendly to bees had 4x as many visits.  Hopefully this listing would fare better –  Bee friendly trees and shrubs

Yes, but can they learn to dust?  Bees are smarter than we thought – or else maybe they are training us.  Hmmm….

Courage in the face of cold!  It will be warm again!
