- 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.
