Abstract
The incidence of tobacco black shank, which is induced by Phytophthora parasitica var. nicotianae, increased rapidly 6-8 wk after transplanting in North Carolina [USA]. Precipitation, daily air temperature, and number of drought days were associated with rapid disease progression after 6-8 wk in resistant and moderately resistant cultivars and prior to 6-8 wk in susceptible cultivars. No single meteorological parameter influenced disease progression more than any other. Models relating meteorological variables to disease progression explained 61-78% of the disease progression variation and can be useful to predict conditions favorable for black shank development.This publication has 0 references indexed in Scilit:
