“…It was demonstrated in some studies that the biocontrol agents having both antagonistic and plant growthpromoting activity could be more effective in controlling plant diseases (Akkopru and Demir 2005;Borrero et al 2006). Similarly, it is assumed in this study that plant growth promotion could be associated with the secretion of auxins, gibberellins and cytokinins by bacterial antagonists (Ramamoorthy et al 2001;Sabuquillo et al 2006;Siddiqui 2004).…”

“…There have been many studies on the application of antagonistic microbes for biocontrol of Fusarium wilts including the use of Pseudomonas spp., Penicillium oxalicum, Bacillus subtilis, nonpathogenic F. oxysporum, Trichoderma spp., and Paenibacillus polymyxa (Duffy and Weller 1995;Fuchs et al 1999;Sabuquillo et al 2006;Hervás et al 19971998;Dijksterhuis et al 1999). The incidence of several soil-borne plant pathogens have also been reduced by using composts made of different raw materials (Borrero et al 2004;Cotxarrera et al 2002;Hoitink and Boehm 1999;Hoitink and Fahy 1986;Lumsden et al 1983).…”

Development of a mode of application of bioorganic fertilizer for improving the biocontrol efficacy to Fusarium wilt

More effective ways of applying biocontrol products should be developed based both on the characteristics of the biocontrol agents and the normal practices of the agricultural producer. A new system was developed to improve the biocontrol efficacy of Fusarium wilt for watermelon production, and this system was tested in pot and field experiments. Biocontrol was achieved by applying a novel bioorganic fertilizer product (BIO) to Fusarium-infested soil. The best biocontrol was obtained by application of a bioorganic fertilizer, BIO, into soil during the nursery phase of watermelon seedling followed by a second application to Fusarium-infested soil when watermelon seedlings were transplanted. In comparison with the controls, the incidence of the disease was reduced by 60-100% in the pot experiment and by 59-73% in the field experiment when the BIO was applied during the nursery stage. After application of BIO during the nursery stage, the number of colony-forming units of Fusarium oxysporum in rhizospheric soil was significantly (P \ 0.05) inhibited compared to the controls. An in vitro experiment showed that the antagonist Paenibacillus polymyxa in the BIO could effectively colonize the rhizosphere of watermelon and proliferate along the extending plant roots. This inhibited growth of Fusarium oxysporum in the rhizosphere of watermelon and protected the watermelon roots from attack by the pathogens. The method used for biocontrol Fusarium wilt disease in watermelon should be a useful strategy to improve field efficacy of other biocontrol agents.

Fusarium wilt of watermelon commonly occurs in locations where the crop has been grown for many seasons. Its occurrence results in a severely decreased watermelon crop. The goal of this study was to assess the capability of a new product (bio-organic fertilizer) to control the wilt in Fusarium-infested soil. Pot experiments were conducted under growth chamber and greenhouse conditions. The results showed that the fertilizer controlled the wilt disease. Compared with control pots, the incidence rates of Fusarium wilt at 27 and 63 days following treatment of the plants with the bio-organic fertilizer at a rate of 0.5% (organic fertilizer + antagonistic microorganisms, including 3 9 10 9 CFU g -1 Paenibacillus polymyxa and 5 910 7 CFU g -1 Trichoderma harzianum) were reduced by 84.9 and 75.0%, respectively, in both the growth chamber and greenhouse settings. The activities of antioxidases (catalase, superoxide dismutase and peroxidase) in watermelon leaves increased by 38.9, 150 and 250%, respectively. In the roots, stems and leaves, the activity of b-1,3-glucanase (pathogenesis-related proteins) increased by 80, 1140 and 100% and that of chitinase increased by 240, 80, and 20%, respectively, while the contents of malondialdehyde fell by 56.8, 42.1 and 45.9%, respectively. These results indicate that this new fertilizer formula is capable of protecting watermelon from Fusarium oxysporum f.sp. niveum. The elevated levels of defense-related enzymes are consistent with the induction and enhancement of systemic acquired resistance of plant.
