Watermelon rind necrosis in Imperial Valley
Watermelon Rind Necrosis (WRN) is a perennial problem in Imperial Valley. As much as 25 percent of the fruit of some local fields may be mildly or severely affected. Last year about $100,000 worth of fruit was lost to this disorder. Watermelon Rind Necrosis has been reported from Hawaii, Texas, and Florida. Bacteria, Erwinia sp., and fluorescent pseudomonads have been implicated by several workers as possible causal agents of rind necrosis.Even though bacteria were most often associated with necrotic rind, the conclusion that Watermelon Rind Necrosis in Imperial Valley is due to bacteria cannot be made on the basis of our findings.
