The UA Campus Repository is experiencing systematic automated, high-volume traffic (bots). Temporary mitigation measures to address bot traffic have been put in place; however, this has resulted in restrictions on searching WITHIN collections or using sidebar filters WITHIN collections. You can still Browse by Title/Author/Year WITHIN collections. Also, you can still search at the top level of the repository (use the search box at the top of every page) and apply filters from that search level. Export of search results has also been restricted at this time. Please contact us at any time for assistance - email repository@u.library.arizona.edu.

| dc.description.abstract | Two rates of the insect active ingredient zetacypermethrin (MustangMax) were evaluated for control of summer insect pests on bermudagrass, with application made about one month prior to harvest. Crop was 22 inches tall when treatments were applied and had a dense stand, which also intercepted much of the treatment. Little difference existed between the two rates of zetacypermethrin in this study. Treatments reduced planthopper numbers by slightly over 50% for the first 9 days after application. Reduction of bermudagrass mirid populations was 45% at two days post treatment, but numbers of this insect were numerically higher in MustangMax treated plants than in untreated plots at subsequent sample dates. Treatments also resulted in significantly lower numbers of damsel bugs and minute pirate bugs at two days post treatment, while only reducing grass thrips numbers by about 20% through 13 days after application. Bark lice were more prevalent in the treated plots, thought due to a reduction of predatory beneficial insects. More effectiveness from this chemistry would be expected earlier in the growing season when plants are shorter, therefore allowing greater coverage and contact with insects as this chemistry is not systemic. | |
