Fusarium wilt

2023 Watermelon trial for Fusarium resistance

July 27, 2023July 27, 2023 cuccap CucCAP Disease Management Team, Cucurbit Crop & Disease Management

Delaying transplanting until the soil has warmed to about 81 degrees at a 4-inch depth can reduce the number of plants with Fusarium wilt.
Eleanor and Fascination are partially resistant cultivars that have been shown to perform better when Fusarium wilt is present. But grafting is more effective…and more expensive

Fusarium Wilt Observed in North Florida Watermelons

April 30, 2022May 5, 2022 cuccap Cucurbit disease and pest reports

Early symptoms of Fusarium wilt appear as dull gray-green leaves which wilt during the hottest time of the day. While plants recover at night, the symptoms eventually become permanent over time. Infected plants will collapse and die.

CucCAP scientists find high prevalence of gummy stem blight resistance to common fungicides

Featured Article

The gummy stem blight fungus, Stagonosporopsis citrulli, is now resistant to fungicides in four chemical classes. The newest resistance is to fungicides in FRAC Code 3. Most isolates (94% of 251) collected from watermelon in South Carolina in 2019 and 2021 were moderately resistant to tebuconazole, a fungicide widely used on watermelon because it is available in low-cost generic products. Highly resistant isolates were cross-resistant to five other fungicides in the same chemical class as tebuconazole: tetraconazole, flutriafol, difenoconazole, prothioconazole, and the newly registered mefentrifluconazole. Currently, only 4% of the isolates are highly resistant, so growers are encouraged to limit use of tebuconazole to one early season application to avoid shifting the population from moderately resistant to resistant.
