ASPARAGUS - ESTABLISHED - GRASS/BROADLEAF WEEDS - MEDIUM - SPLIT APPLICATION

General Information

General Information

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

General Use Precautions

Applied according to directions and under normal growing conditions, Treflan HFP 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 HFP 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 HFP. Under these conditions, delayed crop development or reduced yields may result.

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

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

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

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 HFP 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 “Approved 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 HFP 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 HFP 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 “Approved Crops” section for application timing recommendations for specific crops.

Preemergence Application Immediately After Planting

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

Postemergence and Layby Application

Apply and incorporate Treflan HFP at the recommended rate to the established crop at or before the last cultivation. Required preharvest intervals for treatments with Treflan HFP for certain crops are specified in the “Approved 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.

Limitations, Restrictions, and Exceptions

ASPARAGUS - ESTABLISHED

Before and After Harvest: 1.5 + 1.5 pints / acre.

Apply Treflan HFP to established asparagus as a split application. Treflan HFP will suppress volunteer seedling asparagus and field bindweed when applied as directed. Follow recommended soil preparation, application, and incorporation procedures for Treflan HFP.

Application Timing: Make applications to dormant asparagus in winter or early spring after mature ferns have been removed. Do not apply after new spears begin to emerge. Apply post-harvest applications immediately after harvest in late spring or early summer just before ferns are allowed to develop.

Do not apply more than 3.0 pt/acre on medium soils during any calendar year.

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.
