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

Fig. 6. Efficacy of fungicides in Pythium root rot incidence and production of usable tobacco seedlings (A). All fungicides were applied to the float water. Black column =Root rot incidence, Clear column = Usable 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; Efficacy of the method of application of etridiazole in Pythium root rot incidence and production of usable tobacco seedlings (B). Black column = Root rot incidence, Clear column = Usable transplants. 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.
