Late blight was found in an organic tomato field near Bridgeton today, August 14. This is the first report of late blight in New Jersey this growing season.

Weather conditions this past week have been favorable for its development in most of the mid-Atlantic region. All tomato and potato growers in the state should scout their fields on a regular basis. All tomato and potato growers who have not initiated a protectant fungicide program should do so. For more information on controlling late blight please see the 2014 Commercial Vegetable Production Recommendations: Tomato Section, page F205 and Potato Section, page F128.

If you suspect late blight on your farm please contact your County Ag Agent.

Two light infestations of pepper weevil have been found, one in Oldman’s township and the other in the Hammonton area. In both cases the infestations are relatively small and at this time of season potential yield loss will be less than had the infestations occurred in May or June.  Weevils were also caught at a produce handling facility near Swedesboro.

• Late Blight: There have been scattered reports of late blight in the Northeast region the last few weeks. There have been no reports of late blight in New Jersey to date this summer.
• Cucurbit Powdery and Downy Mildew remain active. All cucurbit growers in the state should include powdery and downy mildew specific fungicides in their weekly maintenance programs. As a reminder, all abandoned fields  need to be disced under or sprayed with gramoxone to reduce inoculum pressure.
• Pepper Anthracnose has been reported in some areas. See Mitigating Losses to Pepper Anthracnose for more information on its control.
• Bacterial problems on tomato and pepper continue to be an issue. The dry weather this past week should have helped slow things down, however, heavy rain is expected in the state on Tuesday.
• Results of a Septoria Leaf Spot trial on parsley this summer at RAREC suggest that resistance  is beginning to develop to the FRAC code 11 fungicide, Quadris, and are similar to results from a trial last fall (see Controlling Septoria Leaf Spot in Parsley). Parsley growers, particularly in the Vineland area, should consider using fungicides such as Fontelis (penthiopyrad, FRAC code 7) or Merivon (fluxapyroxad + pyraclostrobin, 7 + 11) in weekly rotations.

A 24C Special Local Needs label has been approved for New Jersey to increase the labeled rate of Prefar 4-E to 5 to 9 quarts per acre.

Excellent safety has been observed when labeled crops have been treated with the higher rate. Use of the higher Prefar 4-E rate improves control of susceptible annual broadleaf weeds. Note that annual broadleaf weeds NOT controlled by Prefar 4-E, including galinsoga and common purslane, will NOT be controlled by the higher rate.
