Greenhouse IPM update 1.18.19

Things to consider while you are waiting for the snow to start!

If you bring in plant material from Florida – or anywhere really – you should look it over closely to make sure that you are not bringing in any pest insects.  A new aphid has been found in Florida on aluminum plant that can also affect other Pilea spp – the Pilea aphid.  It is very small and bicolored in the adult stage.  More information here:

Yet another invasive species – the spotted lanternfly – is definitely on the move.  Several adults have been found in NYS – including on nursery stock – but so far – and thanks to good inspection – no populations have been found.  To learn how to identify it and prevent its spread, watch our webinars (in conjunction with NE IPM and the Department of Ag and Markets.

Greenhouse IPM update 1.2.19 When is Sevin not Sevin?

I thought this was an interesting post.



Pesticide use is becoming even more complicated.  Note that Sevin no longer contains carbaryl.  This article from Texas A&M AgriLife Extension explains the situation.

I photographed the previous and new product bottles and labels.  The bottle on the left is the previous product that contains carbaryl (100 on label) and the one on the right is the new product (500 on label).  These are completely different active ingredients, both called Sevin.

Please remind your clientele to “Read the Label” when using pesticides!
