SUGARCANE - FINE SOIL (1.0-2.0% S.O.M.)
Authority MTZ DF Herbicide is a dry flowable formulation to be mixed with water and sprayed for selective preemergence or preplant incorporated weed control in soybeans and sugarcane. When applied according to the instructions on the label, Authority MTZ DF Herbicide will control listed broadleaf, and sedge weeds, and provide grass suppression.
Authority MTZ DF Herbicide may be applied in the fall or spring. When applied at recommended rates in the fall, corn or soybeans can be planted in the spring.
The mode of action of Authority MTZ DF Herbicide involves uptake by weed roots and shoots. Preemergence and preplant incorporated applications of Authority MTZ DF Herbicide require rainfall or irrigation to activate the herbicide. The amount of rainfall or irrigation required for activation following application depends on existing soil moisture, organic matter content and soil texture. If adequate moisture (1/2” to 1”) is not received within 7 to 10 days after the Authority MTZ DF Herbicide treatment, a shallow cultivation may be needed to obtain desired weed control. When sufficient moisture is received after dry conditions, Authority MTZ DF Herbicide will provide control of susceptible germinating weeds.
Proper handling instructions: This product may not be mixed or loaded within 50 feet of any wells (including abandoned wells and drainage wells), sink holes, perennial or intermittent streams and rivers, and natural or impounded lakes and reservoirs. This setback does not apply to properly capped or plugged abandoned wells and does not apply to impervious pads or properly diked mixing/loading areas. Operations that involve mixing, loading rinsing, or washing of this product into or from pesticide handling or application equipment or containers within 50 feet of any well are prohibited unless conducted on an impervious pad constructed to withstand the weight of the heaviest load that may be positioned on or moved across the pad. Such a pad shall be designed and maintained to contain any product spills or equipment leaks, container or equipment rinse or washwater, and rainwater that may fall on the pad. Surface water shall not be allowed to either flow over or from the pad, which means the pad must be self contained. The pad shall be sloped to facilitate material removal. An unroofed pad shall be of sufficient capacity to contain at a minimum 110% of the capacity of the largest pesticide container or application equipment on the pad. A pad that is covered by a roof of sufficient size to completely exclude precipitation from contact with the pad shall have a minimum containment capacity 100% of the largest pesticide container or application equipment on the pad. Containment capacities as described above shall be maintained at all times. The above specific minimum containment capacities do not apply to vehicles when delivering pesticide shipments to the mixing/loading site. States may have in effect additional requirements regarding wellhead setbacks and operation containment.
GENERAL APPLICATION INFORMATION
Authority MTZ DF Herbicide is labeled for use on soybeans and sugarcane. DO NOT use on any other crops.
Utilize a boom and nozzle sprayers equipped with the appropriate nozzles, and screens and adjusted to provide optimum spray distribution and coverage at the appropriate operating pressures. Utilize nozzles that produce minimal amounts of fine spray droplets to avoid spray drift or inadequate foliar and soil coverage. Apply a minimum of 10 gallons of finished spray per acre. Be aware that overlaps and slower ground speeds while starting, stopping, or turning while spraying may result in excessive application and subsequent response.
Sprayer must be accurately calibrated before application. Check sprayer during application to be sure it is working properly.
Water or liquid fertilizer must be used as the carrier for Authority MTZ DF Herbicide, when applied alone, or when tank mixed with other soybean or sugarcane herbicides. A jar test for compatibility of liquid fertilizer and Authority MTZ DF Herbicide tank mix is recommended if the compatibility of the liquid fertilizer and Authority MTZ DF Herbicide is unknown.
Continuous agitation during application is required. Avoid overlap. Shut off spray booms while turning, slowing, or stopping, as over application may result. Do not store the sprayer overnight or for any extended period of time with the Authority MTZ DF Herbicide spray mixture remaining in the tank.
Do not premix Authority MTZ DF Herbicide solutions in nurse tanks.
Authority MTZ DF Herbicide has been tested on a number of soybean cultivars, however, it has not been tested on all soybean varieties. The vast majority of cultivars tested when used according to label guidelines have demonstrated tolerance to Authority MTZ DF Herbicide. A limited number of soybean cultivars have shown some level of injury when used according to label guidelines and should not be planted when an Authority MTZ DF Herbicide program is planned.
Authority MTZ DF Herbicide is not recommended for use on the following soybean varieties: Altona, AP55, AP 71, Asgrow 6520, Burlison, Coker 102, Coker 156, Dassel, GL 3202, Govan, Maple Amber, NB 3665, NKS 1884, Paloma 350, Portage, Regal, Semmes, Terra-Vig 505, Terra-Vig 606, Tracy, Vansoy, and Vinton 81. For further information regarding soybean tolerance to an Authority MTZ DF Herbicide treatment consult University or Extension weed management specialists for additional information on specific local varieties or cultivars and any other pertinent information on Authority MTZ DF Herbicide under specific local conditions prior to applying product.
If cool/cold weather or heavy rainfall occurs immediately following an Authority MTZ DF Herbicide application, soybean stunting or stand loss could occur. Yields have not been affected where early season stunting has occurred. Injury to soybeans can also occur under the following conditions: (1) excessive rate for soil type, (2) boom overlap, (3) improper sprayer calibration, (4) error in mixing procedures, (5) when soils have a calcareous surface area or pH greater than 7.5, (6) soil incorporation deeper than recommended, (7) when applied with organophosphate pesticides, (8) when heavy rains occur after application, especially in poorly drained areas, (9) when soybeans are planted less than 1 1/2 inches deep, (10) on any soil with less than 0.5% organic matter.
BAND TREATMENT APPLICATIONS
For band treatments, apply the broadcast equivalent rate and volume per treated acre. To determine these, please refer in the formula given in the label.
When applied in accordance with the General Application information and the specific crop use directions, Authority MTZ DF Herbicide applied alone or in recommended tank mixtures will provide control of the listed weeds.
GRASSES (Suppression Only): Broadleaf signalgrass; Crabgrass, large; Crabgrass, smooth; Goosegrass; Johnsongrass, seedling; Orchardgrass; Panicum, fall; Panicum, Texas
Authority MTZ DF Herbicide may be applied to sugarcane as a preemergence treatment at planting or lay-by timing.
Planting Time and Lay-by Applications
- Use the higher rates for soils of pH less than 7.0. Use the lower rates for pH greater than 7.0 within the rate range.
- Use higher rates for soils of pH less than 7.0 and lower rates for pH greater than 7.0 within the rate range.
Planting Time Application
Authority MTZ DF Herbicide can be applied to newly planted or ratoon sugarcane as a broadcast or banded preemergent soil applied treatment for the control of broadleaf weeds, grasses and sedges in sugarcane.
Use the higher rate on clay soils and/or soils with organic matter content higher than 2 percent. Apply either by air in a minimum of 5 gallons of spray per acre or by ground equipment in a minimum of 10 gallons of spray per acre. Authority MTZ DF Herbicide may be applied with other herbicides registered for use in sugarcane.
Do not apply more than 33.0 ounces (0.928 lbs active) per acre of Authority MTZ DF Herbicide per twelve month season. The twelve month period is considered to begin upon the initial Authority MTZ DF Herbicide application.
Do not graze treated sugarcane or harvest for forage or hay.
