Abstract
Four field trials were conducted in April 1995 and 1996 in Arizona to compare the effectiveness of: 1, a soil drench of isolate D1 of Burkholderia (Pseudomonas) cepacia; 2, isolate D1 barley meal formulation; 3, Deny seed treatment (a peat moss-based formulation of B. cepacia); 4, Deny soil drench; 5, Kodiak seed treatment (a formulation of Bacillus subtilis); 6, a mixture of three fungicides (metalaxyl, triadimenol, and thiram) seed treatment; and 7, a mixture of metalaxyl, triadimenol, thiram, and Kodiak seed treatment to increase cotton stand in the field. Except for D1, the other products are being marketed for the control of cotton seedling damping-off. Only D1 soil drench and a mixture of the three fungicides seed treatment increased cotton stand significantly (P ≤ 0.05) in three of four field trials.
