Plant Fungal Diseases

The Crop Protection Network has a new corn fungicide return on investment (ROI) calculator.

Neopestalotiopsis (NeoP) has emerged as a significant threat to strawberry production in the U.S., largely linked to infected nursery plants. The disease can affect all plant parts, leading to leaf spots, crown rot, plant decline, and reduced yields—though fruit rot is less common in the Mid-Atlantic. Field trials show that cultivar choice and plant health at planting are critical, as fungicides offer limited control. Management efforts should focus on sourcing clean, healthy plug plants and selecting more tolerant cultivars, since infections often originate in nurseries and persist after transplanting.

A variety of information on commercial strawberry production including organic production, pest and weed management, frost and freeze prevention, and more.

Many vineyards are approaching or already within 30 days of the anticipated harvest date for early wine grape varieties. During this window, grape berries are becoming very susceptible to a variety of late-season rots, such as ripe rot, sour rot, Botrytis bunch rot, and other “secondary-fungi” associated with bunch rots.
