TURGRASSES - ADULTS AND/OR LARVAE OF SURFACE FEEDERS (ANNUAL BLUEGRASS WEEVIL, BILLBUGS, ETC.)
APPLICATION TO TURFGRASS
The use of this product will provide plant nutrients as well as providing control of selected insect pests. This product can be used for the control of soil inhabiting pests of turfgrass; for example northern and southern masked chafers, Cyclocephala borealis, C. immaculata, and/or C. lurida; Asiatic garden beetle, Maladera castanea; black vine weevil, Otiorhyncus sulcatus, European chafer, Rhizotrogus majalis; green June beetle, Cotinis nitida; May or June beetles, Phyllophaga spp.; Japanese beetle, Popillia japonica; oriental beetle, Anomala orientalis; Euetheola humulis rugiceps; billbugs, Sphenophorus spp.; annual bluegrass weevil, Listronotus maculicollis; black turfgrass ataenius, Ataenius spretulus; Aphodius spp; Crane flies, Tipula spp.; frit fly, Oscinella frit, chinch bugs, Blissus spp.; fire ants, Solenopsis spp.; cutworms, Agrotis ipsilon, Peridroma saucia, Nephalodes menians; armyworms, Spodoptera spp., Pseudaletia spp.; sod webworm, Crambus spp.; and mole crickets, Scapteriscus spp. This product can be used as directed on turfgrass; for example, in home lawns, business and office complexes, shopping complexes, multi-family residential complexes, airports, cemeteries, parks, playgrounds, and athletic fields.
The active ingredients in this product have sufficient residual activity so that applications for control of subsurface feeders can be made preceding the egg laying activity. The need for an application for control of subsurface feeders can be based on historical monitoring of the site, previous records or experiences, current season adult trapping or other methods. Optimum control of subsurface feeders will be achieved when applications are made prior to egg hatch of the target pest, followed by sufficient irrigation or rainfall to move the active ingredient through the thatch.
The active ingredients in this product have sufficient knockdown and residual activity to provide remedial and residual control of surface feeding pests. Applications for control of surface feeding pests can be made when infestations are anticipated based on historical monitoring of the site, previous records or experience, current season adult trapping or presence of insects at economic thresholds as determined by scouting and/or recommendations of local State extension personnel or other qualified specialists.
Do not apply more than 200 lb. of this product (0.25 lb. of imidacloprid, 0.2 lb. bifenthrin) per acre per application on residential use sites (i.e., around private homes, apartment buildings, condominiums, non-agricultural outbuildings, non-commercial greenhouses, pre-schools or day care facilities). May be applied at up to 400 lb. of this product (0.5 lb. of imidacloprid, 0.4 lb. bifenthrin) per application on non-residential use sites (i.e., around institutional, public, commercial or industrial buildings; parks; recreational areas or athletic fields).
Do not apply when turfgrass areas are waterlogged or the soil is saturated with water. Adequate distribution of the active ingredient cannot be achieved when these conditions exist. The treated turf must be in such a condition that the rainfall or irrigation will penetrate vertically in the soil profile. Total amount applied cannot exceed 400 lb. (0.5 lb. of imidacloprid, 0.4 lb. of bifenthrin) per acre per year.
NOTE: Not for use in commercial greenhouses or on grass grown for seed or on golf courses and sod farms. For use on plants intended for aesthetic purposes or climatic modification and being grown in interior plantscapes, ornamental gardens or parks, or on lawns and grounds.
Apply this product uniformly over the area being treated with normally used granular application equipment. Both drop-type and rotary-type spreaders may be used to apply this product. Avoid the use of spreaders that apply the material in narrow, concentrated bands. Calibrate application equipment prior to use according to the manufacturer’s directions. Check frequently to be sure equipment is working properly and distributing granules uniformly and accurately.
- Avoid runoff or puddling of irrigation water following application. Avoid application of this product to areas which are waterlogged or saturated, which will not allow penetration into the root zone of the plant. Do not apply more than 400 lb. (0.5 lb. of imidacloprid and 0.4 lb. of bifenthrin) per acre per year.
- Treated areas may be replanted with any crop specified on an imidacloprid and a bifenthrin label, or with any crop for which a tolerance exists for the two active ingredients.
- For crops not listed on any imidacloprid and a bifenthrin label, or for crops for which no tolerances for the active ingredients have been established, a 12-month plant-back interval must be observed.
- Do not apply by air.
- Not for use in nurseries or commercial greenhouses.
Consult your local State Agricultural Experiment Station or State Extension Turf Specialists for more specific information regarding timing of application.
NOTE: For optimum control, irrigate if rainfall does not occur within 24 hours after application to move the active ingredient through the thatch. Do not apply more than 400 lb. product (0.5 lb. of imidacloprid active ingredient, 0.4 lb. bifenthrin) per acre per year. Do not apply more than 200 lb. product (0.25 lb. imidacloprid, 0.2 lb. bifenthrin) per acre per application to residential turf. Avoid mowing turf or lawn area until after irrigation or rainfall has occurred so that uniformity of application will not be affected.
In New York State, this product may NOT be applied to any grass or turf area within 100 feet of a water body (lake, pond, river, stream, wetland, or drainage ditch).
In New York State, make a single repeat application of this product if there are signs of renewed insect activity, but not sooner than two weeks after the first application.
- Annual Bluegrass Weevil (Listronotus maculicollis) adults: Time applications to control adult weevils as they leave their overwintering sites and move into grass areas. This movement generally begins when Forsythia is in full bloom and concludes when flowering dogwood (Cornus florida) is in full bloom. Consult your State Cooperative Extension Service for more specific information regarding application timing.
- Annual Bluegrass Weevil (Listronotus maculicollis) larvae: For best results, apply at the first sign of wilting of bluegrass. For the first generation, this wilting often occurs after full bloom of flowering dogwood (Cornus florida).
- Billbug adults: For best results, apply when adult billbugs are first observed during April and May. Degree day models have been developed to optimize application timing. Consult your State Cooperative Extension Service for information specific to your region. In temperate regions, spring applications targeting billbug adults will also provide
control of over-wintered chinch bugs.
- Chinch Bugs: Chinch bugs infest the base of grass plants and are often found in the thatch layer. Irrigation of the grass area before treatment will optimize the penetration of the insecticide to the area where the chinch bugs are located. Chinch bugs can be one of the most difficult pests to control in grasses and the higher application rates (up to 4.6 lb. per 1,000 sq. ft.) may be required to control populations that contain both nymphs and adults during the middle of the summer.
