Pathogen Identification And Control Of Kiwifruit Fruit Stem Anthracnose Of Kiwifruit In Fengxin County

During2011and2012, a new blight disease on fruit stem of kiwifruit broke out inFengxin County, Jiangxi Province, China.90isolates from the diseased fruit stems wereobtained by using tissue isolation, and the pathogenicity was confirmed. The pathogenwas identified as Glomerella septospora based on morphological characters andmolecular identification results. Our Results also showed that G. septospora penetratedfruit stem of kiwifruit through wounds.To achieve the efficacy of control, through selected Cabrio, Nativo, Horizon, and etc.eight kinds of fungicides to stem the fruit stem anthracnose indoors in toxicity screeningtest, the results show that the effect of the drug toxicity: Cabrio＞Nativo＞Horizon＞Nustar＞Score＞Baobei＞Equation pro, so the preferred agents of field testreagents is Cabrio, Nativo and Horizon.In order to further verified the control effect of selected reagents, using the bestthree reagents of indoor toxicity test,Cabrio, Nativo and Horizon integrated withco-related filed cleaning in different habitats, deployment related study of comprehensivecontrol, the test results indicate that the effect of control of the habitat are Cabrio>Horizon> Nativo> water; But the effect of control in the habitat environment ofcleaning grove is significantly better than non-cleaning grove, and the incidence of thekiwi fruit stalk anthrax in habitat environment of cleaning grove is below than non-cleaning grove.
