If we can get a system to test for bacterial problems that’s fast, growers can sleep at night.”īoth Goldman and Bettinger say geranium breeding companies have expressed interest in the technology. You can’t lay awake 10 days to two weeks waiting for test results. You want to get eradication and need to know now. Growers don’t sleep if the crop looks bacterial but they’re not sure. With bacterial diseases, you want to know before the guy down the street knows. “We’ve all lived through the repercussions of Xanthomonas. “It’s an incredible project that has been in the works for three years,” he says. ![]() He’s eager to make it available to growers. Infections are known to have run rampant in individual greenhouses and can cause up to 100 percent loss in geraniums.”įrom the grower’s point of view, Bettinger says this revolutionary test is a godsend. “This number, however, to the greenhouse industry is deceptive. “Typical losses resulting from blight have averaged between 10 and 15 percent,” Goldman says. Xcp is the most destructive disease for geraniums, especially zonal geraniums. ![]() AwardĪccording to USDA’s Floriculture Crops Survey, geraniums represented $300 million in wholesale plant sales in 2006. The opportunity should be explored to use the availability of this technology to assist in breeding for resistance to Xanthomonas in geraniums.” The same technology may be used on other solanacea crops, like potatoes, he adds.ĭümmen Orange Plant Breeder Dr. “This test would allow the supplier to warrant that his material is free from infection prior to shipment, and the receiver to warrant that the material is likewise bacteria free upon receipt. “Ideally, both the supplier and the receiving grower would profit enormously from a rapid, reliable test for Xcp,” Goldman says. The absence of the 1.2-kbp fragment from the controls of Xcp culture medium alone or uninoculated plants is also shown in this panel. The panel B in the bottom shows the presence (indicated by an arrow) of a 1.2 kbp PCR product detected from the Xcp bacterial culture (left) and infected plants (right) and separated through agarose gel electrophoresis and visualized with ethidium bromide staining. The panel A in the top shows the healthy (left) and infected (right) leaves of Pelargonium x hortorum plants. ![]() This figure illustrates the detection of Xanthomonas campestris pv.
