FIELD, SEED, POPCORN AND SILAGE CORN - PREEMERGENCE IN CONVENTIONAL OR REDUCED TILLAGE CORN (MEDIUM OR FINE TEXTURED SOILS) - PERENNIALS
The following directions apply to all uses of BANVEL. Additional precautions and restrictions will be found in each specific use section.
Do not treat irrigation ditches or water used for crop irrigation or domestic uses.
Do not apply this product through any type of irrigation system.
MIXING AND APPLICATION
UNLESS OTHERWISE SPECIFIED UNDER THE INDIVIDUAL USE HEADINGS OF THIS BOOKLET, THE FOLLOWING DIRECTIONS APPLY TO ALL CROP AND NON-CROP USES OF BANVEL. REFER TO INDIVIDUAL USE SECTIONS FOR ADDITIONAL PRECAUTIONS, RESTRICTIONS, APPLICATION RATES AND TIMINGS.
BANVEL is a water-soluble formulation that can be applied using water or sprayable fluid fertilizer as the carrier. If a fluid fertilizer is to be used, a compatibility test (See COMPATIBILITY TEST) should be made prior to tank mixing.
DO NOT apply more than 2 pt of BANVEL (1 lb dicamba) per acre for any single application.
DO NOT exceed more than 4 pt of BANVEL (2 lb dicamba) per acre per year.
Ground or aerial application equipment, which will give good spray coverage of weed foliage, should be used. HOWEVER, DO NOT USE AERIAL APPLICATION EQUIPMENT IF SPRAY PARTICLES CAN BE CARRIED BY WIND INTO AREAS WHERE SENSITIVE CROPS OR PLANTS ARE GROWING OR WHEN TEMPERATURE INVERSIONS EXIST.
Apply 3 to 50 gallons of diluted spray per treated acre when using ground application equipment or 1 to 10 gallons of diluted spray per treated acre (2 to 20 gallons of diluted spray per acre for preharvest uses) in a water-based carrier when using aerial application equipment. Use the higher level of the listed spray volumes when treating dense or tall vegetation. Use coarse sprays.
Select nozzles designed to produce minimal amounts of fine spray particles. Spray with nozzles as close to the weeds as is practical for good weed coverage.
To avoid uneven spray coverage, BANVEL should not be applied during periods of gusty wind or when wind is in excess of 15 mph. Avoid disturbing (e.g., cultivating or mowing) treated areas for at least 7 days following application.
BEST STEWARDSHIP PRACTICES
BANVEL provides effective broadleaf weed and brush control when properly applied. Best stewardship practices in all mixing, loading, and application operations not only maximize weed control, but also protect ground and surface waters and minimize off-target movement.
This chemical is known to leach through the soil into ground water under certain conditions as a result of agricultural use. Use of this chemical in areas where soils are permeable, particularly where the water table is shallow, may result in ground-water contamination.
GROUND AND SURFACE WATERS PROTECTION
1) Point source contamination—To prevent point source contamination, do not mix, load this pesticide product within 50 feet of wells (including abandoned wells and drainage wells), sink holes, perennial or intermittent streams and rivers, and natural or impounded lakes and reservoirs. Do not apply pesticide product within 50 feet of wells. This setback does not apply to properly capped or plugged abandoned wells and does not apply to impervious pad or properly diked mixing/loading areas as described below.
Mixing, loading, rinsing, or washing operations performed within 50 feet of a well are allowed only when conducted on an impervious pad constructed to withstand the weight of the heaviest load that may be on or moved across the pad. The pad must be self-contained to prevent surface water flow over or from the pad. The pad capacity must be maintained at 110% that of the largest pesticide container or application equipment used on the pad and have sufficient capacity to contain all product spills, equipment or container leaks, equipment wash waters, and rainwater that may fall on the pad. The containment capacity does not apply to vehicles delivering pesticide shipments to the mixing/loading site. States may have in effect additional requirements regarding wellhead setbacks and operational containment.
Care must be taken when using this product to prevent: a) back siphoning into wells, b) spills or c) improper disposal of excess pesticide, spray mixtures or rinsates. Check valves or anti-siphoning devices must be used on all mixing equipment.
2) Movement by surface runoff or through soil—Do not apply under conditions which favor runoff. Do not apply to impervious substrates such as paved or highly compacted surfaces in areas with high potential for ground water contamination. Ground water contamination may occur in areas where soils are permeable or coarse and ground water is near the surface. Do not apply to soils classified as sand with less than 3% organic matter and where ground water depth is shallow (less than 8 feet in Arizona). To minimize the possibility of ground water contamination, carefully follow specified application rates as affected by soil type in the product information section of this label.
3) Movement by water erosion of treated soil—Do not apply or incorporate this product through any type of irrigation equipment nor by flood or furrow irrigation. Ensure treated areas have received at least one-half inch rainfall (or irrigation) before using tailwater for subsequent irrigation of other fields.
SENSITIVE CROP PRECAUTIONS
BANVEL may cause injury to desirable trees and plants, particularly beans, cotton, flowers, fruit trees, grapes, ornamentals, peas, potatoes, soybeans, sunflowers, tobacco, tomatoes, and other broadleaf plants when contacting their roots, stems or foliage. These plants are most sensitive to BANVEL during their development or growing stage. FOLLOW THE PRECAUTIONS LISTED BELOW WHEN USING BANVEL.
- Do not treat areas where either possible downward movement into the soil or surface washing may cause contact of BANVEL with
the roots of desirable plants such as trees and shrubs.
- Avoid making applications when air currents may carry spray particles to areas where sensitive crops and plants are growing, or when temperature inversions exist. Do not spray near sensitive plants if wind is gusty or in excess of 5 mph and moving in the direction of adjacent sensitive crops. Leave an adequate buffer zone between area to be treated and sensitive plants. Coarse sprays are less likely to drift out of the target area than fine sprays.
- Use coarse sprays to avoid potential herbicide drift. Select nozzles, which are designed to produce minimal amounts of fine spray particles. Examples of nozzles designed to produce coarse sprays via ground application are Delavan Raindrops, Spraying Systems XR flat fans, or large capacity flood nozzles such as D10, TK10, or greater capacity tips. Keep the spray pressure at or below 20 psi and the spray volume at or above 20 GPA, unless otherwise required by the manufacturer of drift-reducing nozzles. Consult your spray nozzle supplier concerning the choice of drift-reducing nozzles.
- Agriculturally approved drift-reducing additives may be used.
- Do not apply BANVEL adjacent to sensitive crops when the temperature on the day of application is expected to exceed 85ºF as drift is more likely to occur.
- To avoid injury to desirable plants, equipment used to apply BANVEL should be thoroughly cleaned (See PROCEDURE FOR CLEANING SPRAY EQUIPMENT) before reusing to apply any other chemicals.
All crop uses of BANVEL are intended for a normal growing interval between planting and harvest. No crop rotation restrictions exist if normal harvest of treated crop has occurred. If this interval is shortened, such as in cover crops that will be plowed under, do not follow up with the planting of a sensitive crop.
Crops growing under stress conditions such as drought, poor fertility, or foliar damage due to hail, wind or insects, can exhibit various injury symptoms that may be more pronounced if herbicides are applied.
Consult your local or state authorities for possible application restrictions and advice concerning these and other special local use situations. Tank mix recommendations are for use only in states where the tank mix product and application site are registered.
BANVEL may be applied as a band treatment.
The following recommendations are based on BANVEL use rates up to 2 pt per treated acre.
CORN, SORGHUM and SOYBEANS may be planted in the spring following applications made during the previous year. If less than 1 inch of rainfall occurs between application and first killing frost, treated areas should be cultivated to allow herbicide to come in contact with moist soil.
Cultivation may take place before or immediately after ground thaw.
NOTE: THE MINIMUM INTERVAL BETWEEN BANVEL APPLICATIONS AND PLANTING SOYBEANS IS 30 DAYS. Soybean injury may occur if the interval between application and planting is less than what is specified. In areas with greater than 30 inches of rainfall, delay planting for 30 days per pt of BANVEL per treated acre. In areas with less than 30 inches of rainfall, delay planting for 45 days per pt of BANVEL per treated acre.
Exclude days when ground is frozen.
WHEAT may be planted in the fall or spring following applications. Also, spot applications may be made any time prior to crop emergence if crop injury can be tolerated in treated areas. Wheat injury may occur if the interval between application and planting is less than specified.
East of the Mississippi River, the interval is 20 days per pt of BANVEL per treated acre or 1.25 days per 1 ounce. Moisture is essential for BANVEL degradation. Exclude days when ground is frozen.
West of the Mississippi River, the interval is 45 days per pt of BANVEL per treated acre or 3 days per ounce. Moisture is essential for BANVEL degradation. Exclude days when ground is frozen.
Following a normal harvest of barley, oats, or wheat, any rotation crop may be planted. If the interval before harvest is shortened, such as when cover crops will be plowed under, do not follow up with the planting of a sensitive crop.
FIELD, SEED*, POPCORN* AND SILAGE CORN
Observe all precautions, mixing, and application instructions as well as the following:
* Do not apply BANVEL to seed corn or popcorn without first verifying with your local seed corn company (supplier) the Dicamba selectivity on your inbred line or variety of popcorn. This precaution will help avoid potential injury of sensitive varieties.
BANVEL is not registered for use on sweet corn.
Direct contact of BANVEL with corn seed must be avoided. If corn seeds are less than 1 1/2 inches below the surface, delay application until corn has emerged.
Up to 2 applications of BANVEL may be made during a growing season. Do not exceed a total of 1 1/2 pt of BANVEL per treated acre per crop year. Allow two weeks or more between applications of BANVEL. See appropriate section for rate information. For combination options or sequential treatments, refer to appropriate section.
Applications of BANVEL to corn during periods of rapid growth may result in temporary leaning. Corn will usually become erect within 3 to 7 days.
Cultivation should be delayed until after corn is growing normally to avoid breakage.
Agriculturally approved surfactants or sprayable fertilizers (1/2 to 1 gallon per acre of 28%, 30% or 32% urea ammonium nitrate or 2.5 pounds per acre spray grade ammonium sulfate1 may be added to the spray mixture to improve postemergence weed control, particularly in dry growing conditions.
Do not use adjuvants containing penetrants such as petroleum-based oils after crop emergence or crop injury may result.
Corn may be harvested or grazed for feed once the crop has reached the ensilage (milk) stage or later in maturity.
Several synthetic pyrethroid insecticides are labeled for tank mix applications of dicamba. Refer to their label for specific recommendations.
BANVEL will control many ANNUAL broadleaf weeds or give growth suppression of many PERENNIAL broadleaf weeds commonly found in corn.
For best performance, make application when weeds have emerged and are actively growing.
Preemergence control of cocklebur, velvetleaf, and jimsonweed may be reduced if conditions such as low temperature or lack of soil moisture cause delayed or deep germination of weeds.
1Not for use in California.
PREEMERGENCE IN CONVENTIONAL OR REDUCED TILLAGE CORN
BANVEL may be applied after planting and prior to corn emergence. DO NOT apply to coarse textured soils (sand, sandy loam, and loamy sand) until after crop emergence (see Early Postemergence uses below).
Preemergence application of BANVEL does not require mechanical incorporation to become active. A shallow mechanical incorporation is recommended if application is not followed by adequate rainfall or sprinkler irrigation. Avoid tillage equipment (e.g., drags, harrows) which concentrates treated soil over seed furrow.
