Five wild Solanum species were screened against dry root rot disease in glass house condition with commonly cultivated brinjal as control. The disease was scored at different day’s interval on 30th, 45th and 60th days after planting (DAP). Among the wild species screened and evaluated the species S. torvum was observed without any disease incidence i.e (0). The least per cent of disease incidence was observed in S. incanum (38.60%) which was followed by S. xanthocarpum (42.80%), S. viarum (64.20%) and CO2 (78.50 %) susceptible check at 30 DAP. Secondary metabolites were analysed from both wild and control plants. Based on the per cent disease incidence values S. torvum was graded as ‘Resistant’ against M. phaseolina and can be recommended as a best rootstock for brinjal under varying climatic condition especially where the dry climate prevails.

This study aimed to investigate the effect of interaction between Trichoderma harzianum and the fungicide Topsin-M on root rot disease that infected okra in the field. Three fungi were isolated from the root of okra that infected with root rot disease: Fusarium solani, Rhizoctonia solani and Macrophomina phaseolina. The pathogenicity of these fungi was tested and found to be they cause root rot disease on okra, the disease severity was 41.7, 6.7 and 31.7% respectively. The laboratorial experiments showed that T. harzianum had a high antagonism ability with degrees of 1 and 2 against the pathogenic fungi M. phaseolina, F. solani and R. solani respectively. Also, it was found that the fungicide Topsin –M inhibited the growth of all pathogenic fungi with a percent of 100%, while it inhibited the bioagent fungus growth with a percent of 50.4 %, therefore it be recommended for the interaction experiments. The field results showed that using of bioagent T. harzianum and fungicide topsin-M significantly reduced the infection percentage and severity disease of the pathogenic fungi F. solani, R. solani and M. phaseolina to 65.3, 21.20, 13.20, 46.20, 25.70 and 18.20% respectively, compared to each pathogenic fungus alone which were 71.00, 60.20, 60.20, 66.80, 80.20 and 60.20% respectively. The interaction between the bioagent T. harzianum and topsin-M led to increase the plant height, fresh and dry weight of shoot and root systems and the fruit productivity of the examined okra plants .

Actinomycetes were tested for their antagonistic activity against Fusarium udum and Macrophomina phaseolina under in vitro condition. Among the tested isolates of Actinomycetes AC (5) reported highest 82.85 per cent reduction of mycelial growth of Fusarium udum and 85.13 per cent reduction of mycelial growth of Macrophomina phaseolina. In the field experiment, five treatments were tested for the management of wilt and dry root rot disease, T3- ST+ SA with Actinomycetes (AC 5) significantly recorded 71.92 and 70.38 per cent reduction of the wilt and dry root rot diseases, respectively. These biocontrol agents were used an alternative to the chemical fungicide for controlling the wilt and dry root rot incidence and enhanced the plant growth parameters and there by increased yield in redgram.

The activity of Rhizobium japonicum against the soil-borne pathogens Fusarium solani and Macrophomina phaseolina as causative agents of soybean root rot disease in both culture medium and soil was evaluated. Rhizobial culture filtrate caused an inhibition of the fungal radial growth of Fusarium solani and Macrophomina phaseolina on potato dextrose agar medium amended with the filtrate compared with control. The addition of rhizobial culture suspension to the soil contaminated by the two pathogens, Fusarium solani and Macrophomina phaseolina and their interaction, in pots, improved seed germination percentages and reduced the root rot disease index significantly. The sowing of rhizobial coated seeds in soil contaminated by Fusarium solani and Macrophomina phaseolina separately and in combination, in the field, increased seed germination significantly and induced a high reduction in disease severity for the same previous combination under field conditions. These results indicate that rhizobia could be an important element in root rot disease management.
