Widespread resistance to QoIs, DMI and SDHIs fungicides has been reported for Brazilian populations of the wheat blast pathogen Pyricularia oryzae Triticum lineage (PoTl). A pre-existing mechanism not associated with target site mutations indicated DMIs SDHIs, strong indication that PoTl multidrugresistance (MDR). Therefore, main objective this study was test hypothesis SDHI detected in due eff...

In this study, the effects of temperature and duration leaf wetness on development rice blast disease caused by Pyricularia oryzae reactions Edirne Osmancık-97 cultivars against were investigated under controlled environmental conditions. Rice inoculated with a conidial suspension (5x105 conidia ml-1) P. exposed to combinations five different durations (from 6 30 h) four temperatures (20 32°C) ...

Plant growth promoting rhizobacteria (PGPR) are found to control the plant diseases by adopting various mechanisms. Induced systemic resistance (ISR) is an important defensive strategy manifested by plants against numerous pathogens especially infecting at aerial parts. Rhizobacteria elicit ISR by inducing different pathways in plants through production of various metabolites. In the present st...

The fermentation product of herbs by lactic acid bacteria (FHL) was assayed for antifungal activities against Rosellinia necatrix, Helicobasidium mompa, Fusarium oxysporum, Pythium graminicola and Pyricularia oryzae. FHL completely inhibited the growth of R. necatrix, H. mompa, P. graminicola and P. oryzae, and reduced the growth of F. oxysporum by 35%. When the seeds of Medicago sativa L. (alf...
