Effects of some plant activators against Potato wart disease [<em>Synchytrium endobioticum</em> (Schilb.) Per.]
Abstract
Potato wart disease can caused up to 100% yield loses. Disease agent, Synchytrium endobioticum (Schilb.) Per. is a soil borne fungus and is a quarantine pathogen. Due to lack of its chemical control, quarantine measurement is used for the prevention of spread of the fungus. The use of resistant potato cultivars is prevalent around the infected areas. Whereas, the fact that resistant cultivars often lose their trade value results in difficulties in finding the resistant cultivars for planting. Plant activators offer a practical control possibility for plant diseases by triggering natural defence mechanisms of plants. This study aimed to determine the effects of some plant activators on infection ratio of potato wart disease. In pre-trials, six different activators were screened for disease control and three of them, which were more effective than the others Reynoutria sachalinensis (Regalia), Acibenzolar-S-methyl (Actigard) and Lactobacillus acidophilus (Cropset) were selected. These three activators were tested for disease control under two different fields with high and low inoculum levels. All three activators inhibited infection rates of tubers effectively. Especially Actigard was the most effective activator with 89.12% effect. But the activator significantly reduced tuber formation in the field with low inoculum level.
