Abstract: | Summary The sterilized environment prompted the maize stalk rot pathogen Erwinia carotovora f. sp. zeae Sabet to retain its infectivity for a longer period than the unsterilized one. The survival as well as infectivity
potency of the pathogen present in the soil having naturally-infested or artificially-inoculated host plant as debris was
superior to that in the soil or even the soil containing maize stalk tissue.
‘Maize-potato-maize’ cropping pattern effected a considerable increase in the disease incidence due to maintainance of continuity
of life of the pathogen in the intervening potato crop. re]19741113 |
