Abstract:
Bio-controlling of rice blast pathogens could be an alternative and eco-friendly management. Therefore, in this trial, the antagonistic potential of some bio-controlling agents (BCAs) (Trichoderma sp., Bacillus spp., Pseudomonas sp.) were assessed against six rice blast pathogens through in vitro and in vivo trials. Maximum inhibition (72%) was produced by Trichodermma spp. Under glasshouse condition, the infection was best controlled with Trichoderma sp. soil treatment @ 10 g/kg + Bacillus spp. seed treatment @ 10 g/kg following foliar application of pathogen @ 45 days of planting. From this, it was concluded that BCAs could effectively be used for controlling the infection of rice blast diseases. Hence it is recommended for sustaining rice farming. Further study on validation of above findings through location specific field trials is recommended.
