Watermelon is affected several pathogens and pests that are frequently controlled by SDHI compounds. Scientists from North Carolina State University compared the sensitivity of the different pathogens to various SDHIs.
Research which focuses on pest and disease management is at the heart of crop sustainability in Florida’s watermelon industry. Two issues that need immediate attention are whiteflies and fusarium wilt in watermelon.
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
From Clemson Plant Pathologist Tony Keinath. This year’s Fusarium wilt experiment includes 3 seedless cultivars, 3 fungicide treatments applied via drip irrigation, and grafting. preliminary results are based on disease development 10 weeks after transplanting.
Research shows that Carolina Strongback rootstock is not immune to fusarium, but it does have a good level of resistance.
Reported instances are lower than in previous years.
Cucurbit production in Georgia is affected annually by a variety of pests and diseases. Two diseases in particular, fusarium wilt and cucurbit anthracnose, have been a cause of concern for the last five years.
Read about two watermelon diseases that can cause post-transplanting damping-off and plant death in an article from CucCAP sceintist and Clemson Plant Pathologist Tony Keinath.
