Collins, CO. Individual plots were 15-ft of 5-yr-old established bluegrass arranged in a RCB design with four replications. On 29 May, treatments were applied by using a CO compressed-air sprayer delivering 1 gal/1,000 ft . Evaluations were made on 1 Jun and 15 Jun by making six "put-downs" per plot with a Vortis suction sampler (4.1-inch diameter) for 5 seconds each. Both Merit and Meridian significantly reduced numbers of leafhoppers, and Merit suppressed thrips. Neither treatment affected numbers of clover mites.
