Abstract/Contents:Presents a study conducted by the Texas A&M University Research & Extension Center "to determine which insecticides could be used to control grasshoppers on landscape plants, and to determine if any of the treatments would provide residual control." Details methods and materials used during the study, stating that "for each experiment, plants of 'Disco Rose Red' hibiscus, Hibiscus moscheutos, 12-16 in. [inches] high and growing in 6 in. pots, were sprayed till runoff with the respective chemicals." Explains that "two plants were treated with each insecticide in each experimental unit to insure [ensure] adequately treated foliage would be available for several residue tests." Reports that "treatments with two synthetic pyrethroids, Talstar (bifenthrin) and Scimitar (lambda-cyhalothrin) each provided greater than 83% [percent] control within 24 hr [hours] and 100% control of the grasshoppers within 72 hr exposure to the hibiscus leaves that had been treated a day earlier." Provides tables and charts illustrating control levels for each chemical used. Concludes that "a higher level of control may be achieved with these treatments if they are applied directly to the feeding grasshoppers or if the grasshoppers are immediately exposed to the treated foliage."
