only S. riobrave was applied at 0, 22, 54,
108, and 216 IJs/cm2. Due to low viability, additional
clay product was mixed in 15 liters of water to achieve
the appropriate rate prior to placement in the spray
tank. Application was made on October 1, 1998 to the
same experimental plots used in trial 1 (Table 1). Application
procedures were the same as described in
trial 1.
