Abstract/Contents: | "A grid of 4 x 4 ft plots separated by 1 ft wide buffer strips was set-up in a home lawn with a heavy infestation of chinch bugs in Okemos, Mich. After precounts, 5 replications of each treatment were applied on Jul 24, between 11:00 am and 4:00 pm. Temperature at application was 75 F and conditions were still. All products wree[were] applied with a single nozzle, hand held CO2 sprayer from R&D Sprayers. The application was made at 50 psi through an 8003 nozzle. Insecticides were mixed with water and applied at a rate of 242.2 ml/16 ft2 (4 gal/1000 ft2). Postcounts were made 8 d later on 1 Aug. For the precounts and postcounts, each plot was divided in two and each 2 x 4 ft half was counted for 2 minutes. The 2 counts from each replication were then totaled. The test was conducted at a home lawn with a mixture of Kentucky bluegrass and fine fescue, a 0-1/8 inch thatch layer, and sandy soil. The area was damp from rain at the time of application; it had rained several times the previous wk. Many chinch bugs infected with Beauvaria bassiana were sporulating during the postcounts. Chinch bug populations rapidly declined in all plots during the 8 d between treatment and evaluation, presumably due to an ipizootic of Beauveri bassiana. In the final counts all insecticide treatments had less chinch bugs per plot than the untreated. However, the analysis of variance for all treatments was not significant (P=0.215)." |
