CORN (FIELD, POP, SEED, AND SILAGE) - PREPLANT AND PRE-EMERGENCE APPLICATION IN NOTILLAGE CORN - COARSE

General Information

GENERAL INFORMATION

Banvel-k + Atrazine herbicide is a water-dispersible formulation for use in corn, sorghum, or fallow to control annual broadleaf weeds and to suppress perennial broadleaf weeds (refer to General Weeds List Table).

MODE OF ACTION

Banvel-k + Atrazine contains two active ingredients: dicamba and atrazine. Dicamba is readily absorbed by plants through shoot and root uptake, translocates throughout the plant’s system, and accumulates in areas of active growth. Dicamba interferes with the plant’s growth hormones (auxins) resulting in death of many broadleaf weeds. Atrazine is absorbed by roots and shoots and controls weeds by inhibiting photosynthesis.

RESISTANCE MANAGEMENT

With repeated use, atrazine and dicamba have selected for resistant biotypes of some weed species. Combining the two herbicides, which are each active in a similar broadleaf weed spectrum, reduces the risk of selecting for resistant biotypes.

APPLICATION INSTRUCTIONS

Banvel-k + Atrazine herbicide can be applied pre-emergence or postemergence to actively growing weeds as aerial, broadcast, band, or spot spray applications using water or sprayable fertilizer as a carrier. Sprayable fluid fertilizer as a carrier is not recommended for use after crop emergence.

For crop-specific application timing and other details, refer to the Crop-Specific Information section.

To avoid uneven spray coverage, Banvel-k + Atrazine should not be applied during periods of gusty wind or when wind is in excess of 15 mph.

Avoid off-target movement, Use extreme care when applying Banvel-k + Atrazine to prevent injury to desirable plants and shrubs.

SENSITIVE CROP PRECAUTIONS

Banvel-k + Atrazine 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-k + Atrazine during their development or growing stage.

1. Use coarse sprays (volume median diameter of 400 microns or more) to avoid potential herbicide drift. Select nozzles that are designed to produce minimal amounts of fine spray particles (less than 200 microns). Examples of nozzles designed to produce coarse sprays via ground applications are Delavan Raindrops, Spraying Systems XR (excluding 110º tips) flat fans, Turbo Teejets, Turbo Floodjets, 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 gallons per acre, unless otherwise required by the manufacturer of drift-reducing nozzles. Consult your spray nozzle supplier concerning the choice of drift reducing nozzles.

2. Agriculturally approved drift-reducing additives may be used.

AERIAL APPLICATION

Water Volume: Use 2-10 gallons of water per acre. Use the higher spray volume when treating dense or tall vegetation.

Application Equipment: Select nozzles designed to produce minimal amounts of fine spray particles. Make applications at the lowest safe height to reduce the exposure of spray droplets to evaporation and wind. The applicator must follow the most restrictive use cautions to avoid drift hazards, including those found in the labeling as well as applicable state and local regulations and ordinances.

Do not use aerial equipment if spray particles can be carried by the wind into areas where sensitive crops or plants are growing or when temperature inversions exist.

Avoiding spray drift at the application site is the responsibility of the applicator. The interaction of many equipment-and-weather-related factors determine the potential for spray drift. The applicator and the grower are responsible for considering all these factors when making decisions. The following drift management requirements must be followed to avoid off-target drift management from aerial applications to agricultural field crops.

These requirements do not apply to forestry applications, public health uses or to applications using dry formulations.

- The distance of the outer most nozzles on the boom must not exceed 3/4 the length of the wingspan or rotor,

- Nozzles must always point backward parallel with the airstream and never be pointed downwards more than 45 degrees. Where states have more stringent regulations, they should be observed.

The applicator should be familiar with and take into account the information covered in the Aerial Drift Reduction Advisory Information.

GROUND APPLICATION (BROADCAST)

Water Volume: Use 10-50 gallons of spray solution per broadcast acre for optimal performance. Use the higher spray volume when treating dense or tall vegetation.

Application Equipment: 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.

RESTRICTIONS AND LIMITATIONS – ALL CROPS

- Maximum seasonal use rate: See Table below for crop-specific maximum seasonal use rates for Banvel-k + Atrazine herbicide - Banvel-k + Atrazine contains atrazine (0.26 pounds of active ingredient per pint). When tank mixing or making sequential applications with products that contain atrazine, do not exceed the following total combined rates of atrazine.

- Do not apply this product through any type of irrigation system.

- When tank mixing or sequentially applying atrazine or products containing atrazine to corn or sorghum, do not exceed an application rate of 2.0 pounds active ingredient of atrazine per acre for any single application, and the total pounds of atrazine applied (lbs. ai/A) must not exceed 2.5 pounds active ingredient per year.

- When tank-mixing or sequentially applying atrazine or products containing atrazine to crops other than corn or sorghum, the total pounds of atrazine applied (lbs. ai/A) must not exceed the specific seasonal rate limits as noted in the use directions.

- Postemergence application to corn and sorghum must be made before corn and sorghum reaches 12 inches in height.

- Maximum broadcast application rates for corn and sorghum must be as follows:

- If no atrazine was applied prior to corn/sorghum emergence, apply a maximum of 2 lb ai/A broadcast. If a postemergence treatment is required following an earlier herbicide application, the total atrazine applied may not exceed 2.5 lb ai/A per calendar year.

- Apply a maximum of 2.0 lb ai/A as a single preemergence application on soils that are not highly erodible or on highly erodible soils if at least 30% of the soil is covered with plant residues; or

- Apply a maximum of 1.6 lb ai/A as a single preemergence application on highly erodible (As defined by the Natural Resource Conservation Service) soils if < 30% of the surface is covered with plant residues; or 2.0 lb ai/A applied postemergence.

- Pre-Harvest Intervals (PHI):

Field corn forage uses: 60-day PHI

Sweet corn forage uses: 45-day PHI

Preemergent sorghum forage uses: 60-day PHI

Postemergent sorghum forage uses: 45-day PHI.

- Crop Rotation Restriction:

- In some cases of treated crop failure, the area may be replanted to either corn or sorghum during the same cropping season. If corn is replanted, do not apply Banvel-k + Atrazine, Clarity, or Banvel herbicides until after emergence. If sorghum is the replanted crop, either Banvel, Clarity, or Banvel-k + Atrazine can be used as a postemergence application.

- If applied after June 10, rotation with crops other than corn or sorghum the following spring may result in crop injury.

- In the high plains and Intermountain areas of the West, where rainfall is sparse and erratic or where irrigation is required, use only when corn or sorghum is to follow corn or sorghum, or when a crop of untreated corn or sorghum is to precede other rotational crops.

- For soils containing a calcareous surface layer, such as those found in eastern parts of the Dakotas, Kansas, western Minnesota, and Nebraska, injury may occur to soybeans or small grains planted the following year following application.

- Small grains may be planted 10 months following treatment. Do not plant sugarbeets, tobacco, vegetables (including dry beans), or small-seeded legumes and grasses in the spring of the year following application or injury may occur.

- Rainfast Period: Rainfall or irrigation occurring within 4 hours after postemergence applications may reduce the effectiveness of Banvel-k + Atrazine.

- Stress: Do not apply to weeds under stress due to lack of moisture, hail damage, flooding, herbicide injury, mechanical injury, or widely fluctuating temperature, as unsatisfactory control may result.

- Do not apply to crops that show injury (leaf phytotoxicity or plant stunting) produced by any other prior herbicide applications, because this injury may be enhanced or prolonged.

- Do not apply through any type of irrigation system. Do not contaminate irrigation ditches or water used for domestic purposes.

Refer in the label for tank mix information.

Limitations, Restrictions, and Exceptions

CORN (FIELD, POP, SEED, AND SILAGE)

Corn may be harvested or grazed for feed after it has reached the ensilage (milk) stage or later in maturity. Direct contact of Banvel-k + Atrazine herbicide with corn seed must be avoided in preplant or pre-emergence applications. If corn seeds are less than 1.5 inches below the surface, delay corn application until after corn has emerged.

A maximum of 2 applications of marksman may be made per season.

Do not apply Banvel-k + Atrazine to seed corn or popcorn without first verifying with your local seed corn company (supplier) the selectivity of Banvel-k + Atrazine on your inbred line or variety of popcorn. This precaution will help avoid potential injury of sensitive varieties. Banvel-k + Atrazine is not registered for use on sweet corn. Avoid using crop oil concentrates after crop emergence as crop injury may result. Use crop oil concentrates only in dry conditions when corn is less than 5 inches tall and when applying Banvel-k + Atrazine alone or tank mixed with atrazine.

PREPLANT AND PRE-EMERGENCE APPLICATION IN NOTILLAGE CORN

Apply 3.5 pints of Banvel-k + Atrazine per acre on medium or fine textured soils containing 2.5% or greater organic matter. Use 2 pints per acre on coarse soils (sand, loamy sand, and sandy loam) or medium and fine textured soils with less than 2.5% organic matter. Avoid use of Banvel-k + Atrazine in well-drained loamy sand to sand soils, particularly in areas having high groundwater tables.

Banvel-k + Atrazine may be applied for the burndown of emerged weeds before, during, or after corn planting. When planting into a legume sod (e.g., alfalfa or clover), apply Banvel-k + Atrazine after 4-6” of regrowth has occurred.

Restricted Entry Interval
