Late blight update

On Thursday, June 17, two tomato samples from southwest Pennsylvania were confirmed to have late blight.  One was a transplant purchased from a nursery and one from a home garden.

Note: Late blight has not been found yet in Indiana.  Reports of findings last week in Indiana were not accurate.

 

I have confirmed with Michigan specialists that no late blight has been reported in Michigan yet (as of June 14).

Other reports of late blight have included findings on tomato transplants being sold to gardeners in the Winnipeg and Brandon areas, and confirmations in Kentucky, Maryland, and areas of the southern US.  In Michigan, they have found that volunteer potato plants are emerging from fields that had late blight last year.  These plants would present a risk and should be killed or removed immediately.

Spraying Transplant Vegetable Row Middles – What are Your Options?

by Kristen Callow, OMAFRA Weed Management Program Lead – Horticulture

There has been a lot of interest in spraying the row middles of vegetable transplant fields with herbicides using hooded sprayers.  Is this a good idea?  Well . . . it depends on the herbicide.  Some growers have questioned whether or not glyphosate can be sprayed.  This is not a labelled use and is definitely not a good idea.  Why?  Just take a look at Figures 1 through 3 which show the impact of glyphosate drift on tomatoes and cucurbits and Figure 4 which shows glyphosate drift on strawberry using a hooded sprayer.  Other reasons include: Continue reading Spraying Transplant Vegetable Row Middles – What are Your Options?
