On The Lookout on Zoysia: Tuttle Mealybug
 
Roi Levin - Environmental Pest Lawn Services, Inc.
The tuttle mealybug, Brevennia rehi, is a pest of many grass species and occurs nearly worldwide, especially where rice and sugarcane are grown. It was found in Orange County in 2011 and 2012 in association with damage to zoysiagrass. Recently, more infestations have been reported, so it is a pest to be aware of.
 
The tuttle mealybug is typically small (less than 2 mm) and pink.  It can be difficult to see because it hides between the grass blade and the stem. Generally, little is known about the biology of this pest. Infestation by tuttle mealybug should be considered whenever dieback is noticed, especially if the grass blades show white wax or are sticky from honeydew secretion.
 
Very little research has been conducted to determine the best strategies for managing tuttle mealybug in turfgrass. In general, mealybug control is challenging because the insects are difficult to reach with insecticides. They are hard to detect before they reach damaging populations, and their waxy excretions may protect them from control efforts. When populations reach high levels, it may take several weeks or months to reduce populations below damaging levels.
 
Although tuttle mealybug is primarily found near the base of the plant, collecting and discarding of grass clippings from infested lawns may help reduce the population. Mealybugs are most effectively controlled with thoroughly applied systemic insecticides. Neonicotinoid products are likely to be most effective because they are systemic and have longer residual activity. A newer systemic compound, cyantraniliprole, may be an effective option although it has not been tested against tuttle mealybug. Pyrethroids and carbamates are not systemic and may initially reduce the population but will not provide lasting control and may require multiple applications. Combination products that contain pyrethroids and neonicotinoids may provide initial contact toxicity as well as longer systemic control. Horticultural oils may also provide supplemental control if thoroughly applied to the treated area. Always follow label directions and restrictions when applying these products

New Nematicide:
Nimitz Pro G (Fluensulfone) from QualiPro/Control Solutions
 
Now labeled for use on golf course, athletic field, sod farm, and lawn. Novel chemistry, new chemical class. Caution label, minimal PPE. Has systemic activity, so works on both ectoparasites (in soil) and endoparasites (in roots). Limited to 4 kg/ha/year (240 lb product/Acre/year). On established turf, Dr. Crow's best results have been with 4 monthly applications of 60 lb/A or 3 monthly applications of 80 lb/A. For sod farm rescue treatment, best results have been from a single application of 240 lb/A made 2 months before harvest. Limited residual activity. Research with improved formulations is ongoing.
