Determining “Practical” Fungicide Resistance Development and Drift in the Control of Cucurbit Powdery Mildew in Pumpkin

Fig. 1. Percent powdery mildew development on the adaxial (B,D) or abaxial (A,C) leaf surfaces of pumpkin cultivar Howden in response to nine fungicide treatments at the end of the production season following five different fungicide programs in 2006 (A,B) and 2007 (C,D).

Fungicide treatments are: Control = Water only; Q = Quintec; N + B = Nova + Bravo; N = Nova; P = Pristine; S = Sulfur; B = Bravo; T = Tanos; C = Cabrio; and A = Amistar.

Bars with no lower case letters in common are significantly different (α = 0.05) according to Tukey's HSD.
