NO-TILL SOYBEANS - MEDIUM

General Information

General Information

Treflan 4D herbi cide is an herbicide for the preemergence control of annual grasses and broadleaf weeds. Treflan 4D may be applied in liquid sprays of water or liquid fertilizer, or impregnated on dry bulk fertilizer. To reduce loss of herbicidal activity, Treflan 4D should be soil incorporated within 24 hours after application unless otherwise specified in specific use directions or supplemental labeling. Treflan 4D may be tank mixed or followed by overlay or postemergence treatments with other herbicides to improve the spectrum of weeds controlled. Treflan 4D controls weeds by disrupting growth processes during germination. Treflan 4D does not control established weeds.

General Use Precautions

Applied according to directions and under normal growing conditions, Treflan 4D will not harm the treated crop. Over-application may result in crop injury or rotational crop damage from herbicide carryover.

Uneven application or improper incorporation of Treflan 4D can result in erratic weed control or crop injury. Seedling disease, cold weather, deep planting, excessive moisture, high salt concentration, or drought may weaken crop seedlings and increase the possibility of damage from Treflan 4D. Under these conditions, delayed crop development or reduced yields may result.

Do not apply Treflan 4D to soils that are wet or are subject to prolonged periods of flooding as poor weed control may result.

Do not use Treflan 4D on any crop grown in Pecos county or Reeves county, Texas.

In Montana, uses of Treflan 4D are limited to those described in supplemental labeling. Refer to supplemental labeling for crops and specific use directions.

Soil Texture Guide for Application Rates

Rate recommendations for incorporated treatments of Treflan 4D are based on soil texture class (coarse, medium, or fine) and soil organic matter content. A fine textured soil (e.g., clay loam) will require a higher application rate than a coarse textured soil (e.g., loamy sand). In the table below, find the soil texture class (coarse, medium, or fine) corresponding to the soil texture to be treated. Choose the proper rate for each application based on the soil texture class and specific crop recommendations. Do not exceed recommended rates.

COARSE (LIGHT) SOILS: sand, loamy sand, sandy loam

MEDIUM SOILS: loam, silty clay loam, silt loam, silt, sandy clay loam

FINE (HEAVY) SOILS: clay, clay loam, silty clay loam, silty clay, sandy clay, sandy clay loam

Silty clay loam and sandy clay loam soils are transitional soils and may be classified as either medium or fine textured soils. If silty clay loam or sandy clay loam soils are predominantly sand or silt, they are usually classified as medium textured soils. If they are predominantly clay, they are usually classified as fine textured soils.

Application Methods

General

As spray volume decreases, the importance of accurate calibration and uniform application increases. Check calibration and uniformity of spray application daily. To avoid spray drift, do not apply when winds are gusting or when wind speed is greater than 15 mph.

Ground Broadcast Application

Apply Treflan 4D in 5 to 40 gallons of liquid carrier per acre (broadcast basis), using any properly calibrated, low pressure herbicide sprayer that will apply the spray uniformly. The carrier may be water or liquid fertilizer as specified for the crop to be treated in the Crops section of the label.

For band application, adjust herbicide rate and spray volume in proportion to the band width and row width treated.

Aerial Broadcast Application

Apply Treflan 4D in 5 to 10 gallons of water per acre. Adjust pump pressure, nozzle arrangements, speed, and application height to provide uniform application to the soil surface. Use swath markers or flaggers to assure proper swath width interval.

Application Timing

Preplant Incorporated Application

Treflan 4D may be applied and incorporated prior to planting when soil can be worked and is in a condition that allows thorough mixing to insure uniform incorporation. See Crops section for application timing recommendations for specific crops.

Preemergence Application Immediately After Planting

Apply and incorporate Treflan 4D immediately after planting and prior to crop germination. Adjust incorporation equipment so as to avoid disturbance of planted seed. Refer to the Crops section of the label for crop specific instructions.

Postemergence and Layby Application

Apply and incorporate Treflan 4D at the recommended rate to the established crop at or before the last cultivation. Required preharvest intervals for treatments with Treflan 4D for certain crops are specified in the Crops section of the label. Crop cover may prevent uniform soil coverage from over-the-top sprays. To avoid this problem, use drop nozzles or directed sprays to achieve uniform soil coverage.

Fall Application

Treflan 4D may be applied in the fall for weed control in the crop of the following growing season in all crops for which Treflan 4D is recommended as a preplant incorporated treatment. Refer to Crops section for any crop specific fall application instructions. In the states of California, North Dakota, South Dakota and Minnesota, apply and incorporate Treflan 4D any time between September 1 and December 31. In all other states, fall apply Treflan 4D between October 15 and December 31.

Fall application of Treflan 4D is not recommended on fields that remain wet or are subject to periods of flooding. Ground may be bedded up over winter. On bedded ground, reduce beds to desired height before planting, by moving some treated soil from beds into furrows. Where soil is left flat over winter, care should be taken not to turn up untreated soil during spring bedding operations. Destroy established weeds during seedbed preparation. Weeds established in furrows as a result of exposing untreated soil should be destroyed before planting.

Refer in the section of the label for “Incorporation Directions”.

Guineagrass; itchgrass (raoulgrass): See special instructions for control in sugarcane in the Crops section.

Johnsongrass (from seed) (rhizome): 2See special instructions for control in cotton, soybeans, fruit and nut crops and vineyards in the Crops section.

Panicum (spreading panicgrass): See special instructions for control in cotton and soybeans in the Crops section.

Red rice: See special instructions for suppression or partial control in soybeans in the Crops section.

Shattercane (wild cane); pigweed: See special instructions for control in soybeans in the Crops section.

Field bindweed: See special instructions for control in fruit and nut crops and vineyards in the Crops section.

Pigweed (palmer amaranth): Suppression only in areas of the southwest U.S. where tolerance to trifluralin has been observed. Consult your local extension service or product representative for information regarding alternative weed control practices.

For 72 Hour Incorporation Delay in the state of Arizona and California information refer in the supplemental label.

Limitations, Restrictions, and Exceptions

NO-TILL SOYBEANS

Apply a tank mixture of Treflan 4D herbicide plus Canopy herbicide and a crop oil concentrate as preplant surface applied treatment to control existing weeds and provide preemergence control of susceptible weeds during the cropping season of full season, narrow-row no-till soybeans. The tank mix of Treflan 4D plus Canopy with crop oil concentrate should be surface applied as a broadcast spray at least three weeks before planting. For best results, soybean row spacing should be 15 inches or less and planting should occur before May 15. Rainfall of at least 0.5 inches is required within 3 to 5 days after application to activate Treflan 4D, otherwise weed control may be variable.

Use Rate for Canopy 75DF

- 8 oz/acre

Use of Additional Postemergence Herbicides:

In addition to Canopy plus crop oil concentrate, other postemergence herbicides, may be added to the tank mix to control existing weeds. These include 2,4-D, Gramoxone Extra and Roundup. Refer to the labels of these additional tank-mix products for use rates.

Precautions:

- The user must comply with all directions for use, precautions and restrictions on the labels for Treflan 4D and the tank mix product.

- Read and follow use directions and precautions before use.

Restricted Entry Interval

12 hours

Exception: If the product is soil-injected or soil incorporated, the Worker Protection Standard, under certain circumstances, allows workers to enter the treated area if there will be no contact with anything that has been treated.
