TAILIEUCHUNG - Evaluation of bio-controlling agents against potato foliar pathogens

Bio-controlling of potato foliar pathogens could be an alternative and eco-friendly management. Therefore, in this trial, the antagonistic potential of some bio-controlling agents (BCAs) of Trichoderma spp. (Trichoderma asperillum, Trichoderma longibrachiatum and Trichoderma harzianum) and Bacillus spp.(Bacillus cereus, Bacillus siamensis, Bacillus amyloliquefaciens, Bacillus safensis, Bacillus subtilis, Bacillus flexus and Bacillus megaterium) were assessed against six foliar pathogens of potato origin (Alternaria solani, Alternaria alternata, Phomaexigua, Curvularia lunata, Bipolaris sorokiniana and corynospora cassicola) through in vitro and in vivo trials. Trichoderma harzianum and Bacillus subtilis were better than other BCAs against the pathogens. The overall inhibition was with Trichoder maharzianum and with Bacillus subtilis. Under glasshouse condition, the infection was best controlled with Trichoderma harzianum soil treatment @ 10 g/kg + Bacillus subtilis 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 potato foliar diseases. Hence it is recommended for sustaining potato farming. Further study on validation of above findings through location specific field trials is recommended. | Evaluation of bio-controlling agents against potato foliar pathogens
