Pythium Root Rot of Flue-Cured Tobacco Seedlings Produced in Greenhouses: Factors Associated with its Occurrence and Chemical Control

Fig. 5. Effect of contaminated Styrofoam trays with Pythium myriotylum in the development of root rot (□) and production of usable tobacco seedlings (■). Means within root rot or usable seedlings followed by the same letter are not significantly different according to Fisher’s least significant difference (LSD) test, P ≤ 0.05.
