CORN - REDUCED TILLAGE SYSTEM - MEDIUM - GREATER THAN 14 DAYS BEFORE PLANTING
FulTime herbicide is intended for preplant, preemergence, or early postemergence use in corn. Use of this product in corn is limited to field corn, production seed corn, silage corn, sweet corn and popcorn. Do not apply this product to any crop other than corn.
FulTime is a unique combination of the herbicides acetochlor and atrazine plus the antidote or safener dichlormid. While the acetochlor provides weed control, the dichlormid safens corn against herbicide injury. FulTime may be applied to the surface or incorporated into the top 1-2 inch layer of soil. It is recommended for control alone, or in tank mix combinations as indicated, for the weeds listed in the \"Target Weeds\" section of these use directions. FulTime controls weeds by interfering with normal germination and seedling development. FulTime does not control established or germinated weeds present at application.
Use Precautions and Restrictions
- On the following soil types, do not apply this product within 150 feet of any well where the depth to groundwater is 30 feet or less: sands with less than 3% organic matter; loamy sands with less than 2% organic matter; or sandy loams with less than 1 percent organic matter. See the figure for additional clarification.
- FulTime should not be used on corn seed stock such as Breeders, Foundation, or Increase.
- Aerial Application: Do not apply this product using aerial application equipment.
- Do not use flood irrigation to apply or incorporate this product.
- Do not contaminate irrigation water used for crops other than corn or water used for domestic purposes.
- Do not apply FulTime before pre-irrigation in irrigated areas.
- Applied according to directions and under normal growing conditions, FulTime will not harm the treated crop. During germination and early stages of growth, extended periods of unusually cold and wet or hot and dry weather, insect or plant disease attack, carryover pesticide residues, the use of certain soil applied systemic insecticides, improperly placed fertilizers or soil insecticides may create abnormal conditions that weaken crop seedlings. FulTime used under these abnormal conditions could result in crop injury.
- Protection of Ground Water and surface Water: This product may not be mixed or loaded within 50 feet of intermittent streams and rivers, natural or impounded lakes and reservoirs. This product must not be applied within 66 feet of the points where field surface water runoff enters perennial or intermittent streams and rivers or within 200 feet of natural or impounded lakes and reservoirs. If this product is applied to highly erodible land, the 66-foot buffer or setback from runoff entry points must be planted to crop, seeded with grass or other suitable crop.
This product must not be mixed or loaded, or used within 50 feet of all wells, including abandoned wells, drainage wells, and sink holes. 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 of 100% of the capacity of the largest pesticide container or application equipment on the pad. Containment capacities as described above shall be maintained at all times. The above-specified minimum containment capacities do not apply to vehicles when delivering pesticide shipments to the mixing/loading site.
Additional State imposed requirements regarding wellhead setbacks and operational containment must be observed.
- Tile-Outletted Terraced Fields Containing Standpipes To ensure protection of surface water from runoff through standpipes with tile-outlets in terraced fields, one of the following restrictions must be followed in applying atrazine to tile-outletted terraced fields containing standpipes:
1. Do not apply this product within 66 feet of standpipes in tile-outletted terraced fields.
2. Apply this product to the entire tile-outletted terraced field and immediately incorporate it to a depth of 2-3 inches in the entire terraced field.
3. Apply this product to the entire tile-outletted terraced field under a no-till practice only when high crop residue management practices are used. High crop residue management is described as a crop management practice where little or no crop residue is removed from the field during or after crop harvest.
- Product must be used in a manner that will prevent back siphoning in wells, spills or improper disposal of excess pesticide, spray mixtures or rinsates.
- Do not apply under conditions that favor runoff or wind erosion of soil containing this product to nontarget areas. To prevent off-site movement due to runoff or wind erosion:
- Avoid treating powdery dry or light sandy soils when conditions are favorable for wind erosion. Under these conditions, the soil surface should first be settled by rainfall or irrigation.
- Do not apply to impervious substrates such as paved or highly compacted surfaces or frozen or snow covered soils.
- Do not use tailwater from the first flood or furrow irrigation of treated fields to treat nontarget crops unless at least ½ inch of rainfall has occurred between application and the first irrigation.
- Do not apply when wind conditions favor drift to non-target sites. To minimize spray drift to nontarget areas:
- Use low-pressure application equipment capable of producing a large droplet spray.
- Do not use nozzles that produce a fine droplet spray.
- Minimize drift by using sufficient spray volume to ensure adequate coverage with large droplet size sprays.
- Keep ground-driven spray boom as low as possible above the target surface.
- Make application when the wind velocity favors on-target product deposition (approximately 3 to 10 mph). Do not apply when wind velocity exceeds 15 mph. Avoid application when gusts approach 15 mph.
- Low humidity and high temperatures increase the likelihood of spray drift to sensitive areas. Avoid spraying during conditions of low humidity and/or high temperatures. Do not apply during inversion conditions.
- Maximum Application Rate: The maximum application rate for Fultime on corn is 5 qt per acre per year. This amount of product is equal to 3 lb per acre of acetochlor active ingredient (ai) and 2 lb per acre of atrazine ai.
- Atrazine Maximum Use Rate Limitations
Maximum broadcast application rates for corn must be as follows:
- If no atrazine was applied prior to corn emergence, apply a maximum rate of 2 pounds active ingredient per acre broadcast. If a post-emergence treatment is required following an earlier herbicide application, the total atrazine applied must not exceed 2.5 pounds active ingredient per acre per calendar year.
- Apply a maximum of 2 pounds active ingredient per acre as a single preemergence broadcast application on soils that are not highly erodible or on highly erodible soils (as defined by the Natural Resources Conservation Service) if practicing conservation tillage and at least 30% of the soil surface is covered with plant residues at planting, or
- Apply a maximum of 1.6 pounds active ingredient per acre as a single preemergence broadcast application on highly erodible soils (as defined by the Natural Resources Conservation Service) if less than 30% of the soil surface is covered with plant residues at planting; or 2.0 pounds active ingredient per acre if only applied postemergence.
- Preharvest Interval: Do not apply this product within 60 days of harvest for field corn forage uses or 45 days for sweet corn forage uses.
- Postemergence applications to corn must be made before the crop reaches 12 inches in height.
- Resistance Management: This product contains atrazine and thus may not control weeds that are known or suspected to be triazine tolerant or \"resistant.\" Following many years of continuous use of atrazine or chemically related (triazine) products, biotypes of certain weeds may develop herbicide tolerance and may no longer be effectively controlled. Where triazine tolerance (resistance to control) is known or suspected and weeds controlled by atrazine are expected to be present along with \"resistant\" biotypes, it is recommended that atrazine be used in combination or in sequence with a registered non-triazine herbicide that is effective against these weeds. If only \"resistant\" biotypes are expected to be present, use an effective nontriazine herbicide that is registered for use on corn.
Application Directions – Corn
Application Timing and Methods
For the optimum period of effective weed control during the time most critical to corn production, preplant applications of FulTime should occur as close as possible to planting. Preemergence applications should occur as close as possible to planting, but prior to weed emergence.
Postemergence applications should occur prior to weed emergence or in tank mix combination with a product that controls emerged weeds.
Note: Do not apply FulTime to sweet corn as an early postemergence application.
Early Preplant: On medium and fine textured soils (see Table 1), FulTime may be applied up to 30 days prior to planting.
Preplant Incorporation: FulTime and certain tank mixes may be mechanically incorporated in the top 2 inches of the soil with field cultivators, discs, or spring tooth harrows at any time within 14 days prior to planting. Improper incorporation, excessive crop residues, or poor soil tilth may result in erratic, streaked or otherwise unsatisfactory weed control. Do not mix FulTime deeper than 2” into the soil and avoid moving or shaping soil after incorporation.
Preemergence Surface: FulTime and certain tank mixes may be applied to the soil surface as a broadcast or banded application. Precipitation or sprinkler irrigation of at least 0.25 inch is required to bring FulTime into contact with germinating weed seeds. If rain or sprinkler irrigation does not occur within 7 days after application, weed control may be improved by using a rotary hoe, or similar equipment, to incorporate the herbicide.
Incorporation equipment should be run at a shallow depth to avoid disturbance of germinating corn seed. Erratic weed control resulting from exposure of untreated soil may occur if surface soil is moved or reshaped after incorporation.
Postplant-Preemergence: FulTime may be applied immediately after planting but prior to corn emergence. If rain or sprinkler irrigation does not occur within 7 days after application, weed control may be improved by using a rotary hoe, or similar device, to shallowly incorporate the herbicide. Do not disturb germinating corn seed. Erratic weed control resulting from exposure of untreated soil may occur if surface soil is moved or reshaped during incorporation.
Banding Preemergence: FulTime may be applied in a 10 to 14 inch band after corn planting but prior to corn emergence. If rain or sprinkler irrigation does not occur within 7 days after application, weed control may be improved by using a rotary hoe or similar device to incorporate the herbicide. Do not disturb the germinating corn seed. Erratic weed control resulting from exposure of untreated soil may occur if surface soil is moved or reshaped during incorporation.
Early Postemergence: FulTime may be applied early postemergence to corn up to 11 inches tall. Applications must be made prior to weed seedling emergence or in a tank mix combination that controls the emerged weeds. Read and follow restrictions and directions on tank mix product labels.
Sprinkler Irrigation: Do not apply FulTime by sprinkler irrigation. Use a sprinkler system only to incorporate FulTime after application. After FulTime has been applied, a sprinkler irrigation system set to deliver 0.25 to 0.75 inch of water per acre may be used to incorporate the product. Using more than 0.75 inch of water could result in reduced performance. On sandy soil low in organic matter, use no more than 0.5 inch of water. Do not use flood irrigation to apply or incorporate FulTime.
Cultivation should be delayed as long as possible. If weeds develop, a shallow cultivation or rotary hoeing will generally result in improved weed control. If FulTime was incorporated, cultivate less than one-half the depth of incorporation.
If cultivation is necessary due to soil crusting, compaction, or escaped weeds adjust equipment to run shallow and minimize soil movement. This will decrease the possibility of diluting or moving the herbicide from the weed control zone.
Soil Texture and Organic Matter
The use rate of FulTime is determined by a combination of two factors, soil texture and organic matter, which must be determined prior to application. Different soil textures are grouped into three textural classes (coarse, medium and fine) as outlined in Table 1. Soil texture and organic matter content of the soil may be determined from soil survey information and/or by laboratory analysis and must be known in order to select the proper rate from Table 2.
Control of yellow nutsedge requires a minimum of 3.5 quarts per acre. Incorporation will improve control.
Activity may be reduced under dry conditions or when early preplant applications are made more than 14 days before planting. Sequential herbicides or application of additional atrazine may be needed for complete control.
Best control is achieved when FulTime is applied within 5 days of planting and rainfall occurs shortly after application or mechanical incorporation is used to activate the herbicide. If rainfall does not occur within 7 days after application, shallow cultivation will enhance activity. Excessive rainfall after application may reduce control. Under adverse weather conditions and/or heavy infestations, a cultivation or follow-up herbicide may be need
Refer in the label regarding tank mix information.
Reduced Tillage Systems
Application can take place up to 40 days before planting or after planting. Optimal weed control will be obtained when applications are made as close to planting as possible, but before weeds emerge. In reduced or no-till systems, it is recommended that a burndown herbicide such as paraquat (Gramoxone) or glyphosate (Glyphomax, Roundup or Touchdown) or 2,4-D be tank mixed with FulTime if emerged weeds are present at application.
Do not apply more than 14 days before planting in coarse textured soils.
Rates are for single applications. Split applications of FulTime may be used by applying at least 60% of the recommended rate up to 30 days before planting and the remaining 40% at planting.
