Summary
A study of the germination of micro- and macro-conidia ofFusarium vasinfectum introduced into the wilt infected soils amended with microelements was made employing modified Cholodny’s slide technique.
Statistical analysis of the results showed the micro-elements, concentrations, incubation periods and the interacting factors to be highly significant from the point of view of retardation of conidial germination.
Percentage germination of the conidia in all the amended soil samples, excepting manganese 50 p.p.m., was much lower than that of the unamended control soil. Zinc, molybdenum, lithium, aluminium, nickel, boron, cobalt and manganese were correspondingly inhibitive in the order mentioned.
