- There have been no new reports of Late blight this this past week. All abandoned tomato fields should be mowed down or burned down with herbicide once harvesting is done.
- Pepper anthracnose remains active. Weekly maintenance sprays should continue as long as harvesting continues in fields where anthracnose is active.
- Following the heavy rains and with more rain expected over the weekend, bacterial leaf spot in pepper and marginal necrosis and leaf spot in leafy greens are being reported. Fungal leaf spots are also being reported. Preventative fungicide programs will help reduce fungal and bacterial problems in leafy greens.
- Cucurbit downy mildew has been confirmed on cucumber in New Jersey. Downy mildew is beginning to be reported on many other cucurbits in other parts of the country. All cucumber growers should continue with a downy mildew-specific fungicide to their weekly fungicide programs. All cucurbit growers need to scout on a regular basis and should mow or burn off fields when harvesting in done.
