| Abstract/Contents: | Presents a study to evaluate Meridian (thiamethoxam), a new product from Novartis Crop Protection. The objective of the study "was to compare the rate, application timing and irrigation effects of this new pesticide on the control of Japanese beetle grubs on turfgrass." Results include that "thimethoxam controls Japanese beetle grubs at levels comparable to both Merit and Mach 2. These levels often exceed 95% control. Thimethoxam can be applied preventatively and boasts a very long activity window. However...this chemical is most effective when applied near egg hatch. Thiamethoxam can also be effective when applied as a curative control, late in the season. While efficacy falls off over time, there appears to be a significant window of opportunity for this product to work well after egg hatch. While the effectiveness of the product is enhanced if application is followed by irrigation, watering delays of 3 or more days did not significantly fluence its performance. All formulations of the product tested performed equally well. Grubs contacted by the product appear to quit feeding within hours, but do not die for periods of up to 1-2 weeks. It is important to remember that it is the grub feeding that most insecticide applications are designed to mitigate. Once the feeding is terminated, the turfgrass can resume normal growth. Some level of client education is needed if expectations of rapid grub death persist." Concludes that "thiamethoxam (Meridian) is a very effective control product against Japanese beetle grubs." |
