the D1 soil drench increased the number of emerged seedlings significantly (P < 0.05), relative to the control (not treated with D1) in non-herbicide-treated soils and in soils treated with trifluralin.
In a post emergence damping-off microcosm experiment, the D1 soil drench caused a significant (P < 0.05) increase in seedling survival only in non-herbicidetreated soil and in soils treated with pendimethalin and trifluralin.
In two field trials conducted at Safford and Tucson, the D1 soil drench increased cotton stand significantly (P < 0.05), relative to the control, in non-herbicidetreated plots and in plots treated with trifluralin.
Cotton stand was significantly (P < 0.05) increased by Denyr soil drench only in non-herbicide-treated plots in Tucson field trial. Denyr seed treatment was inefficient in the presence or absence of the herbicides.
