Local conditions, crop varieties, and application method may affect performance of this product. User should consult local extension service, agricultural experiment station, or university weed specialists, and state regulatory agencies for recommendations in your area.
Best results are obtained when product is applied to young succulent weeds that are actively-growing. Application rates lower than recommended will not be satisfactory on susceptible annual weeds. For perennial weeds and conditions such as the very dry areas of the western states, where control is difficult, the higher recommended rates should be used. When product is used for weed control in crops, the growth stage of the crop must be considered. Some plants and weeds, especially woody varieties, are hard to control and may require repeat applications. Application rates should be 1 to 5 gallons of total spray by air or 5 to 25 gallons by ground equipment unless otherwise directed. In either case, use the same amount of HELENA 2010 per acre. HELENA 2010 should not be allowed to come into contact with desirable, susceptible plants such as beans, cotton, fruit trees, grapes, legumes, ornamentals, peas, tomatoes and other vegetables. HELENA 2010 should not be used in greenhouses. If stored below freezing, it may be necessary to warm product to 40ºF and agitate before using. This does not affect the efficiency of the product. Spray equipment used to apply HELENA 2010 or other products containing 2,4-D should not be used for any other purpose until thoroughly cleaned with a suitable chemical cleaner.
Use calibrated spray equipment for all types of applications to assure applying the recommended amount of spray mixture per acre. Use sufficient spray volume within the ranges specified to obtain good coverage of weeds.
HELENA 2010 is absorbed sufficiently within 1 hour after application to provide adequate weed control.
Ground Broadcast Spray: Unless otherwise specified in the appropriate crop or non-crop directions, apply in 5 or more gallons of spray solution per acre. Use enough spray volume to provide uniform coverage of weeds, taking into account
the amount of vegetation present and the type of application equipment to be used. As crop canopy and weed density increase, a higher spray volume may be needed for equivalent coverage and weed control. Typical crop applications utilize 10 to 50 gallons of spray solution per acre, while certain high-volume non-crop applications may utilize more than 100 gallons per acre. Use coarse sprays to minimize potential spray drift. Do not apply with hollow-cone nozzles or other nozzles that produce fine spray droplets. Boom spraying with flat-fan or low-volume nozzles is generally most suitable for ground broadcast applications.
Ground Band Spray: Determine band equivalents to broadcast rates and volumes by the formulas on the label.
Aerial Broadcast Spray: Unless otherwise specified in the appropriate crop or non-crop directions, apply in 1 to 5 gallons of spray solution per acre. For best coverage and weed control, as well as reduced potential for spray drift, a minimum of 3 gallons per acre is suggested. Avoid using nozzles or nozzle configurations that generate fine droplets. One configuration usually found to be suitable includes straight-stream nozzles (such as disk with no swirl plate) directed straight back along the wind stream. Mechanical flagging or GPS (Global Positioning Systems) is suggested to
obtain more uniform application.
With fixed-wing or helicopter application, an exactly even swath deposition may not be achieved, and consequently, crop injury or pesticide nonperformance may result wholly or in part. Do not apply by air during periods of thermal inversion. Avoid application if potential for drift is excessive and/or susceptible crops are growing in the vicinity.
PISTACHIOS, FILBERTS, POME FRUITS, STONE FRUITS, AND TREE NUT ORCHARDS
Do not use in California.
HELENA 2010 is comprised of a 2,4-D acid formulation that may be used in low-volume ground application equipment. The product is used in directed applications to control broadleaf weeds in established pistachio, pome fruits, stone fruits and tree nut plantings and orchards. HELENA 2010 is to be applied as a broadcast treatment in the row middles of established trees as well as a band application to control many broadleaf weeds in the tree rows and the orchard floor.
Note: Established and transplanted stock must be a least (1) one year old and in good growing conditions.
The precise and uniform application of HELENA 2010 is essential to obtain satisfactory economic control while minimizing the potential injury to the trees. Avoid direct contact with the fruit, foliage, lower limbs, stems, tree trunks and any exposed roots.
It is best to use a fixed boom with flat-fan nozzles at not more than 25 psi. For small concentrated infestations, small areas, individual weeds, or as a follow up application, spot treating is recommended with hand held nozzle sprayer. Do not apply HELENA 2010 when conditions favorable to drift are present.
Most annuals will best controlled when they are actively-growing either in the spring or fall. Most biennials are best controlled when they are in the seedling to rosette stage. Sequential applications may have to be utilized to obtain the best results. Perennials that are either in the early bud to bloom stage or during fall regrowth have to best chance of being controlled at this time.
For improved broadleaf control, HELENA 2010 may be applied in combination with other approved products. The combination must be used in accordance to the most restrictive label limitations of the product in the tank-mix. Both products must be labeled for the site of application. Dosages of the tank-mix must not cause either product to exceed the tolerance established for that active ingredient on the use site to be applied on. All applications of the tank-mix must be in accordance with Federal, State, and local use limitations.
HM-2010 is not to be applied to sandy or shallow soils or to dry soils without vegetation in Pistachio, Pome Fruit, Stone Fruit or Tree Nut Orchards. Best results with HELENA 2010 can be
obtained when the product is applied 1 - 2 days following irrigation.
Do not apply the product immediately prior to irrigation or irrigate immediately following an application.
DO NOT APPLY HELENA 2010 THROUGH ANY TYPE OF IRRIGATION SYSTEM.
DOSAGE RATES FOR BROADLEAF WEED CONTROL
The following dosage rate recommendations are for broadcast applications. The proper amount of HELENA 2010 to be used in banded or row applications must be determined by using the formula on the label.
Recommended Spray Volumes: Generally 1 - 10 gallons per acre is sufficient, but in many cases 10 - 25 gallons may be needed to obtain adequate coverage.
Note: Do not graze of feed cover crops from treated orchards to livestock. Do not apply during windy conditions or extremely high temperatures.
TREE NUTS (ALMOND, FILBERT OR HAZLENUT, PECAN, BLACK AND ENGLISH WALNUT)
HELENA 2010 is to be applied for the control of unwanted vegetation on the orchard floors. It is important to avoid contact with the fruit, foliage, tree trunks, lower limbs and exposed brace roots. Two applications 30 days apart are permitted per year.
Note: Do not cut orchard floor forage for hay within 7 days of application.
HELENA 2010 will control or partially control the following as well as many other noxious plants susceptible to 2,4-D.
