Abstract
Lentil (Lens culinaris) is an important pulse crop in India. Fusarium wilt caused by Fusarium oxysporum f. sp. lentis (Fol), is a major biotic constraint in lentil production. The present investigation was undertaken to evaluate the efficacy of combination products of fungicides and bio-agents against Fol under in vitro and in vivo conditions. Fungicides were evaluated using the poisoned food technique, while the antagonistic activity of bio-agents was studied using dual culture technique. Among seven combination products of fungicides, carbendazim 12% + mancozeb 63% was the most effective fungicide in restricting the colony diameter of the pathogen. In field conditions, the seed treatment with carbendazim 12% + mancozeb 63% at 2.5 g/kg seed performed best in both yield and seed quality parameters. Among the bio-agents tested, Trichoderma asperullum gave the best results in suppressing pathogen growth under in vitro conditions. The seed treatment with the combination of T. asperullum + Pseudomonas fluorescens at 5 g/kg seed showed improvement in seed yield and seed quality parameters in the field. The present study has provided chemical and biological measures for the integrated management of lentil wilt.
期刊介绍:
Journal of Phytopathology publishes original and review articles on all scientific aspects of applied phytopathology in agricultural and horticultural crops. Preference is given to contributions improving our understanding of the biotic and abiotic determinants of plant diseases, including epidemics and damage potential, as a basis for innovative disease management, modelling and forecasting. This includes practical aspects and the development of methods for disease diagnosis as well as infection bioassays.
Studies at the population, organism, physiological, biochemical and molecular genetic level are welcome. The journal scope comprises the pathology and epidemiology of plant diseases caused by microbial pathogens, viruses and nematodes.
Accepted papers should advance our conceptual knowledge of plant diseases, rather than presenting descriptive or screening data unrelated to phytopathological mechanisms or functions. Results from unrepeated experimental conditions or data with no or inappropriate statistical processing will not be considered. Authors are encouraged to look at past issues to ensure adherence to the standards of the journal.
