Late blight was found in commercial potato field near Leipsic, DE today. The wet weather forecasted for most of this week looks favorable for potential late blight development in New Jersey. Growers should continue to scout their fields on a regular basis and apply weekly protectant fungides whenever they can get into the field. To date, there has been one reported case of late blight on tomato in New Jersey (Mercer County). If you suspect late blight on your farm please contact your county agent.
Pepper Anthracnose Reported
The first cases of pepper anthracnose are being reported. Pepper anthracnose can be extremely destructive causing 100% loss if left uncontrolled. No peppers are resistant to anthracnose.
Growers with a history of pepper anthracnose on their farm or in particular fields should be highly diligent and scout their fields on a regular basis looking for ‘hot spots’.
Pepper anthracnose always starts out as a ‘hot spot’ and then fans out with the prevailing direction of the wind. The hot, wet weather and isolated afternoon and evening showers in many areas have been ideal for anthracnose development. If a ‘hot spot’ is found, all fruit (of any size) from the area and from nearly plants should be strip-picked and discarded appropriately. [Read more…]
Late Blight Found on Tomato in Mercer County
Late blight has been found in a 2 acre organic tomato field in Mercer County. This is the first report of Late blight in New Jersey this growing season.
All tomato and potato growers in New Jersey should scout thier fields immediately, especially if fields have not been scouted in the the last 5 to 7 days. At this point, this is just an isolated case. Late blight has not been reported elsewhere in the state. All tomato and potato growers should continue with their regular protectant fungicide programs. The extremely hot weather (> 90 degrees) the last few days should help reduce the threat of late blight as long as the isolated rain showers have missed your farm.
If you suspect late blight on your farm please contact your county agent. For more information on the control of Late blight please see the 2013 commercial vegetable production recommendations guide.
