Strawberry crops in southern Indiana are nearing full bloom, but growers face two major concerns: frost risks and Neopestalotiopsis infection. As temperatures fluctuate, some early blooms may have been damaged by recent low temperatures. Growers must remain vigilant to protect their crops from further frost damage, which could impact future yields.
In addition to frost, Neopestalotiopsis, a fungal disease, has been confirmed in the field. Some plug plants, particularly those planted on black plastic mulch, have shown stunted growth and, unfortunately, some did not survive the winter. For surviving plants, the key question is whether they are worth saving. According to plant pathologists, even healthy-looking plants should be carefully monitored, as the disease can persist and spread in the field.
Fungicides, such as Switch, Thiram, and products in FRAC Group 3, have proven effective in managing Neopestalotiopsis. Applying these treatments can help protect the remaining healthy plants and prevent the spread of the disease to nearby unaffected crops.
Meanwhile, bare-root plants planted on white plastic and covered with straw have begun to grow new leaves. These plants, while not yet showing flower buds, are recovering well after being protected from winter temperatures by straw. The removal of the straw in early March allowed the plants to resume growth.
The good news for strawberry growers is that new cultivars with improved resistance to Neopestalotiopsis will soon be available. These plants, developed through breeding programs in Florida and California, may offer better tolerance to the disease. However, their performance in Indiana’s climate remains to be seen.
For more information on managing Neopestalotiopsis and other strawberry diseases, growers can consult resources from experts at the University of Florida and the University of Kentucky.
