Glufosinate Plus Imazapyr
Extended Control
RM43®-2 is a nonselective water-soluble herbicide for application as a foliar spray for the control of a broad spectrum of emerged annual and perennial grass and broadleaf weeds. RM43®-2 will also control certain woody species*. THOROUGH SPRAY COVERAGE IS IMPORTANT. Visual effects and control from application of RM43®-2 occur within 2 to 4 days after application under good growing conditions.
*Not for use on woody species in California.
This product is nonselective and will injure or kill all green vegetation contacted by the spray. Avoid all contact with foliage or green tissue of desirable vegetation. Avoid direct spray contact with green, thin, or uncalloused bark of desirable vegetation or plant injury may result. If desirable vegetation is contacted, rinse the sprayed portion with water immediately.
Weed control may be reduced when applications are made to weeds under stress due to drought or cool temperatures. Weeds under stress or in dense populations will require application at the highest rate specified. Refer to the How to Apply section of this label.
Where to use:
Industrial sites, Petroleum tank farms, Lumberyards, Manufacturing Sites, Storage Areas, Airports, Roadsides, Curbs, Sidewalks, Driveways, Parking areas, Brick walks, Gravel Paths, Patios, Vacant lots, Paved areas (including crack and crevice), Warehouse areas, Urban areas, Recreational areas, Play areas, Tennis courts, Fencerows, Along fences of paddocks, corrals, feedlots, and livestock holding areas, Dry Ditchbanks, Around domestic dwellings, Around farm buildings and barns, Agricultural uncultivated areas, Shelter beds, Farm yards, Farm premises, Outdoor buildings, structures, and shelters such as beef barns, hog barns, dairy barns, stables, dog kennels and poultry houses, and for establishment and maintenance of wildlife openings.
Only apply to locations where no vegetation growth is desired for up to one year.
When to use:
- Thorough spray coverage is important. Apply to bare ground or when weeds are present. If weeds are taller than 6 inches, mow or cut down weeds and remove debris before treatment and allow for 2 weeks of new growth. Contact with soil is important for extended control. If woody vines or brush is mowed or cut, wait until full leaf formation before treatment.
- To prevent growth of weeds under asphalt driveways, play areas, tennis courts and parking areas, apply this product before laying surfacing materials.
- Treat area uniformly to maximize results.
- Re-treatment every 6 to 8 months may be necessary in areas of heavy rainfall.
How to use:
Apply on a sunny day with temperatures above 60°F. Avoid product runoff to nearby desirable plants. In soils with heavy clay, weed control may exceed one year.
TOTAL VEGETATION CONTROL (BAREGROUND)
Use hand operated spray equipment such as backpack sprayers, pump-up sprayers or sprinkling cans, or ATV/Tractor mounted sprayers. Mix 4 fl. oz. RM43®-2 (equivalent to 0.03 lb. ai glufosinate and 0.003 lb. ai imazapyr) with water to produce 1 to 10 gallons of spray solution and apply to 1,000 sq. ft. Uniformly spray the mix over area where total vegetation control and bareground is desired. Optimum performance will be achieved from applications to actively growing weeds in early summer. Use 1 to 10 gallons of water depending on spray speed and equipment used to deliver 4 fl. oz. RM43®-2 per 1,000 sq. ft.
SPOT OR DIRECTED APPLICATIONS
Use this product as a spot or directed spray application using 2 to 4 fluid ounces of product (0.016 lb. ai glufosinate/0.0016 lb. ai imazapyr to 0.03 lb. ai glufosinate/0.003 lb. ai imazapyr) per gallon of water. Mix 2 to 4 fluid ounces of product per gallon of water depending upon the weed and stage of growth as shown in the following sections. Spray undesirable vegetation foliage on a spray-to-wet basis. Ensure uniform and complete coverage. Use a coarse spray. Backpack, pumpup, and hydraulic sprayers may be used. Thoroughly clean the sprayer following use.
BROADCAST OR BOOM APPLICATIONS
Apply 64 to 192 fl. oz. (2 to 6 quarts) of product (0.5 lb. ai glufosinate/0.05 lb. ai imazapyr to 1.5 lbs. ai glufosinate/0.15 lb. ai imazapyr) per acre (1.46 to 4.4 fl. oz. per 1,000 sq. ft.) depending upon the weed and stage of growth as shown in the following sections. Use a minimum of 40 gallons of water per acre with a minimum of 30-psi spray pressure.
Tank Mixes for Noncrop Uses
RM43®-2 is compatible in tank mixes with many other herbicides including non-selective herbicides. It is the pesticide user’s responsibility to ensure that all products are registered for the intended use. Read and follow the applicable restrictions and limitations and directions for use on all product labels involved in tank mixing. Users must follow the most restrictive directions for use and precautionary statements of each product in the tank mixture.
A compatibility test must be conducted with any potential tank mix partner with RM43®-2, except with any one of those listed above. Using a clear glass quart jar, conduct the test as described below:
- Fill the jar three-quarters full with water.
- Add the appropriate amount of herbicide in the following order: (a) dry flowable, (b) wettable powder, (c) aqueous suspensions, (d) flowables, (e) liquids and (f) solutions and emulsifiable or liquid concentrates. Shake or gently stir jar after each addition to thoroughly mix.
- After adding all ingredients, let the mixture stand for 15 minutes and then look for separation, large flakes, precipitates, gels, and heavy oily film on the jar or other signs of incompatibility.
- If the compatibility test shows signs of incompatibility, do not tank mix the product tested with RM43®-2.
Precautions:
Harmful if swallowed. Harmful if absorbed through skin. Causes moderate eye irritation. Avoid contact with skin, eyes or clothing.
