Galls and Cinnamon extracts were more effective in inhibiting B. cinerea growth than the other plant extracts. in vivo experiments, all plant extracts with different concentrations which applied as dipping treatment decreased disease severity % (DS %) on wounded and unwounded strawberry fruits which inoculated with B. cinerea when compared with control treatment. the tested concentrations of Galls, Clove and cinnamon extracts were generally more effective than other extracts in controlling strawberry fruit rot infection. There were no significant differences between the four strawberry cultivars in disease index on the same level of each plant extract concentration. In general, application with Galls and Clove extracts on strawberry fruits either by spraying or dipping was effective in decreasing DS % when compared with control of wounded or un-wounded fruits. Controlling B. cinerea using Trichoderma spp. in vitro, T. harzianum (isolate 1), T. hamatum (isolate 1) and T. hamatum (isolate 2) were the most effective bio-agents in reducing the fungal growth. With regard to controlling strawberry fruit rot infection using Trichoderma spp. culture filtrates and fungicides in vivo, spraying the wounded and un-wounded strawberry fruits in or with three sterilized culture filtrates of three Trichoderma isolates pre-inoculation with B. cinerea decreased the strawberry fruit rot infection on the four-tested strawberry cultivars.","PeriodicalId":168502,"journal":{"name":"Egyptian Journal of Crop Protection","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115418501","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Generally, all treatments reduced significantly number of root galls; egg-masses; soil, root population density of the M. javanica and increased tested plant morphological characters i.e., plant height; number of main branches; fresh weight of whole plant and yield parameters such as, number of umbels; its fresh and dry weights (g/plant), and fruit yield (g/plant ).Dual application of both HA and irrigation with MW combined gave better results more than the solely one in controlling of M. javanica and all plant characteristics during the tested two winter seasons. Combined treatment of (HA 1500 ppm + MW) gave the highest reduction percentages in M. javanica population (71.0 and 71.8%) through the two successive seasons, respectively. In addition, application of the same combined treatment gave a best results of gall index (1.5 and 1.5); egg-masses production (7.0 and 8.0), in the both seasons, respectively, and a better enhancement in Khella morphological characters and its yield parameters.
