Leaf spot has a negative effect on the aesthetic value of panicle hydrangea, and this report will assist with monitoring distribution of the disease as well as developing management recommendations.Natamycin is a new postharvest biofungicide for citrus and some other fruit crops in the United States that can be effectively used in recycling drench or flooder treatments. These types of applications necessitate sanitation of the fungicide solution to ensure that it remains free from contamination by bacteria that potentially are human pathogens. In in vitro experiments, heated (48°C) citric acid (1,100 μg/ml or 2,200 μg/ml) amended with sodium dodecylbenzensulfonate (SDBS; 55 μg/ml or 110 μg/ml, respectively) significantly reduced viability of E. coli in natamycin solutions by >5 log10 as compared to the control. In laboratory studies with Penicillium digitatum-inoculated lemon fruit, 1,000 μg/ml natamycin mixed with lactic or citric acids (1,000 μg/ml each) and with or without SDBS (55 μg/ml) was effective in significantly reducing green mold. Natamycin mixed with lactic acid at 2000 μg/ml or higher, however, caused fruit injury resulting in browning and pitting of the rind. Natamycin was incompatible wiin in citrus packinghouses utilizing heated recirculating fungicide systems.Huanglongbing (HLB), caused by Candidatus Liberibacter asiaticus, is currently the most destructive disease of citrus and threatens production in all affected areas. There is no cure. Benign Xylella fastidiosa strain EB92-1 provided good control of Pierce's disease of grapevine by inducing host resistance; therefore, we evaluated the strain for the biological control of HLB in citrus. Treatment was by injection into the trunk of the trees. Strain EB92-1 was shown to colonize citrus and provided control of HLB by reducing both the incidence of symptomatic trees and the perce
