Response of Dry Bean to Sulfentrazone Plus Imazethapyr

Table 2

Percent visual injury 2 and 4 WAE and height for four dry bean types treated with PRE applications of sulfentrazone, imazethapyr, or sulfentrazone plus imazethapyr. Means followed by the same letter within a column (a–d) or row (X--Z) in each section are not significantly different according to Fisher’s Protected LSD at 𝑃<0.05^a.
