Tebuconazole

Study carried out of this disease over a period of time revealed that Rhizoctonia solani Kuhn affects the yield severely whenever it occurs at any stage of the crop. In spite chemical measures like copper oxychloride is recommended based on the previous studies on Rhizoctonia spp., the new fungicides need to be evaluated to find out the
effective and economic fungitoxicants with which the disease can be controlled. Keeping in mind the seriousness of the disease, it was planned to elucidate the biocontrol and fungicidal capacity as soil and seed treatment against the pathogen, R. solani and also to evolve suitable management strategies to prevent the losses incurred due to Rhizoctonia root rot of chilli. In the present field experiment, soil application with Trichoderma harzianum in combination with seedling dip treatment with Tebuconazole 2DS was most effective in minimizing the Rhizoctonia root to incidence (8.55%) followed by soil application of Pseudomonas fluorescence in combination with seedling dip treatment with (11.74%) as compared to other treatments. Further the treatment having the seedling dip treatment with Tebuconazole 2DS in combination of soil drenching of Tebuconazole 50% + Trifloxystrobin 20% WG was also effective shows that this new fungicide is also effective against R. solani. All the treatments in the field trial were found significantly increased the yield as compared to control. Highest yield of green chilli (145.27 q/ha) was obtained in the treatment of soil application of T. harzianum @ 10 kg/ha in combination with seedling dip treatment of Tebuconazole 2DS.
