How do you mix triclopyr 4?
Triclopyr 4 mix rates differ based on the application technique and target plant. Mix 3/8 (0.375 oz.) to 3/4 (0.75) fluid ounces of Alligare Triclopyr 4 per 1000 square feet in 1 to 2 gallons of water for spot treatments on ornamental turf. Please refer to the label for for exact application rates.
What do you mix triclopyr with?
Natural regions in Iowa are vulnerable to invasion by exotic woody plants due to disturbances. Buckthorn, honeysuckle, and multiflora rose are three common invasive woody species in Iowa.
Pulling, mechanical removal, and repetitive mowing are examples of non-chemical management methods. Herbicides are the most effective and cost-efficient control solution in many instances. To control woody plants, three different types of herbicide treatments are routinely utilized.
After mechanical removal of the woody plant, cut surface treatments are applied to prevent resprouting. While the wound is still fresh, the herbicide should be sprayed soon after cutting. The herbicide only needs to be administered to the cambium, the tissue directly beneath the bark, on larger trees. Herbicides can be administered with a squirt bottle or a tiny sprayer, or they can be painted on the surface.
Most species are resistant to Roundup (glyphosate) at a 50 percent dilution (one part Roundup to one part water). For cut surface applications, only use concentrated formulations with at least 40% active ingredient. Tordon RTU (picloram) is a premixed cut surface treatment product. This product should be used with caution because picloram can be absorbed by the roots of nearby trees and plants, causing serious damage.
Herbicide is applied to the lower 12 inches of stems and trunks in basal bark treatments. To accelerate herbicide transport through the bark, the herbicide is administered with an oil-based carrier (diesel fuel, kerosene, bark oil). Dyes designed for basal applications allow the applicator to clearly detect if the target has been covered and if there is excessive off-target spray. Because the bark on larger trees may decrease herbicide absorption, basal sprays are most effective on trees with a diameter of less than four to six inches. Trees can be treated at any time of year, but the stems must be completely dry before treatment. The bark should be completely wetted with the spray, but it is not necessary to wait until it runs off.
The efficiency of several herbicides authorized for basal bark application varies depending on the target species. Triclopyr is offered under the trade names Garlon, Remedy Ultra, Tahoe, and Tailspin and is effective against most invasive woody species. For basal bark treatments, only the ester formulation (e.g. Garlon 4) should be used because it is oil soluble (essential when combining with oil) and esters penetrate bark better than amine formulations like Garlon 3A. Most species can be controlled with a mixture of 20 ounces of herbicide and one gallon of oil-based carrier. Garlon concentrate comes in 2.5 gallon canisters, which may be too much for certain people. Pathfinder II is a ready-to-use triclopyr formulation for general use that does not require dilution. This type of product appeals to many land owners because of its convenience and small quantity.
To maintain consistent control, foliar sprays must cover the entire plant canopy. They can be constructed from the time the leaves have fully expanded through the onset of fall color. If applied in the middle to late summer, it may be less effective if done during extended periods of hot, dry weather. Foliar sprays pose a higher danger of herbicide interaction with nearby sensitive vegetation than other methods, especially when spraying large plants. To reduce herbicide off-target movement, applications should be conducted on days with low wind velocity (less than 10 miles per hour).
Triclopyr is available in two forms: amine (Garlon 3A) and ester (Triclopyr) (Garlon 4). Mix one to three ounces Garlon 4 or two to four ounces Garlon 3A per three gallons of water for foliar treatments. The ester formulation can be applied to either the foliar or basal bark. Avoid using the ester formulation in locations where the temperature is over 85 degrees Fahrenheit or where the herbicide may come into contact with water (streams, ponds, etc.). The amine formulation can be used in situations where the spray will come into touch with standing water, making it useful for reducing willows around pond edges.
The majority of brush control treatments found in garden stores are a blend of two or three foliar-applied growth regulator herbicides. Triclopyr-based products are often more effective on woody species than 2,4-D, dicamba, or other herbicides. Garden shop goods usually have lower quantities of active ingredient than products intended for agricultural or commercial application. To ensure appropriate mixing, follow the instructions on the label. These garden store treatments are fine for little jobs, but a commercial formulation like Garlon may be more cost-effective for larger infestations.
Brush herbicides are effective at very low concentrations. To keep them from invading attractive plants, extreme caution is required. Herbicide residues are difficult to remove from a sprayer, so a second sprayer should be purchased expressly for applying herbicides. Despite the fact that most herbicides have a low acute toxicity, precautions should be made to limit your exposure to the chemical. The herbicide label will specify the protective clothes that must be worn when employing the product (e.g. rubber gloves, long-sleeved shirts, eye protection, etc.).

How long does it take for triclopyr 4 to work?
How long does Triclopyr take to take effect? Although you will notice the effects of Triclopyr soon after application, it usually takes two to three weeks for a plant to die.
Can you mix triclopyr and 2 4 D?
Crossbow Specialty Herbicide – 2, 4-D & Triclopyr is mixed at a rate of 1 1/3 fl oz Crossbow Specialty Herbicide – 2, 4-D & Triclopyr per gallon of water. Application instructions can be found on the product label.
Do you need surfactant with triclopyr?
Dish soap may interfere with the chemical process, making herbicides less effective. Hi-Yield 3/8 – 3/4 oz. (2.25-4.5 teaspoons) per gallon of water per 1,000 sq. ft. Triclopyr Ester Ultra is administered at a rate of 3/8 – 3/4 oz. (2.25-4.5 teaspoons) per gallon of water per 1,000 sq. ft (8 – 16 oz. per acre). Complete application directions can be found on the label. A non-ionic surfactant is advised for best performance, but it is not needed by the label.
Can you mix Roundup and triclopyr?
When using glyphosate and triclopyr together, there are a few things to keep in mind. Incompatibility occurs at high concentrations, and precipitate forms in the spray mixture. This effect can be mitigated in two ways. The first is to keep spray carrier volumes under 15 gallons per acre and to avoid keeping unused mix if possible.
