Abstract

Charcoal rot of maize is a widely distributed throughout the world causing sever economic losses and incited by the fungal pathogen Macrophomina phaseolina. The main objective of this experiment is toidentify the important IDM components to control charcoal rot disease of maizeunder field condition. Out of different componental treatments tested, the treatment invoving Soil application of Vermicompost enriched with T. viride (2 × 109 cfu/g)@250kg/ha was found to be the best treatment in terms of disease reduction (65 %) and increased grain yield (39%) with heighest C:B ratio of 1:1.35. However, the treatment involving foliar application of Azoxystrobin 18.2% w/w + Difenoconazole 11.4% w/w SC @0.1% at knee high stage was very closely follows in terms of disease reduction (56%) and grain yield improvement (29%) with C:B ratio of(1:1.34). Othar components like Chitosan and VAM also recorded significantly good results interms of disease reduction (54.5%, 49.4%) and grain yield improvement of (32.3%, 34.6%) indicating their potentiality to utilize them in integrated charcoal rot management of maize.

Conclusion

The results from the experiment indicates that the components like soil application of vermicompost enriched with T. viride, foliar application of chitosan, soil application of VAM and foliar application of Azoxystrobin 18.2% w/w + Difenoconazole 11.4% are vital components that can play a very important role in integrated management of charcoal rot of maize.
