ONION GROWN FOR SEED - NORTHEASTERN STATES
GENERAL USE INFORMATION
Galigan H2O may be applied for preemergence and postemergence weed control. All directions and restrictions for use found in the general use information and specific crop sections of the label must be followed.
In order for Galigan H2O to provide maximum preemergence activity: Prior to application, the bed or soil surface should be smooth and free of crop and weed trash (decaying leaves, clippings, dead weeds, etc.). Leaves and trash may be removed by blowing the area to be treated or by thoroughly mixing the trash into the soil through cultivation prior to herbicide application. After application, at least one-quarter inch (1/4 inch) of irrigation or rainfall should occur within 3 or 4 weeks after application. The best results from Galigan H2O are from applications to established beds or soil surfaces that are left undisturbed during the time period for which weed control is desired. Cultural practices that result in redistribution or disturbance of the soil surface after treatment will decrease the herbicidal effectiveness of Galigan H2O. Cutting water furrows or cultivations that mix untreated soil into treated areas will also reduce the effectiveness of the treatment.
Selective weed control: Some products listed on the label provide selective weed control. Selective weed control occurs when the target weeds are killed without impact to desirable crops or vegetation.
Select proper application rates based on soil conditions, weed spectrum, and desired period of residual weed control.
Preemergence Application: Where rate ranges are given, use the lower rate in the rate range on coarse textured soils with less than 1% organic matter. Use higher rates in the rate range on medium to fine textured soils, soils containing greater than 1% organic matter, or where a longer period of residual weed control is desired.
Postemergence Application: Where a rate range is given, use higher rate in rate range for heavy weed infestations, weeds in advanced stages of growth, or where a longer period of residual weed control is desired.
ONIONS GROWN FOR SEED
Galigan H2O may be used as a postemergence application to onions grown for seed for early postemergence control of certain annual broadleaf and grassy weeds. Initial spray application should be made only when the onions have reached the development stage specified in the DOSAGE section and the SPECIFIC USE RESTRICTIONS section of the label. Galigan H2O can cause necrotic lesions, twisting, pigtailing, or stunting of the onion plants. Injury will be more severe if applications are made immediately following or during cool, wet weather and/or if applications are made prior to the development stage of the onion plants as specified in the DOSAGE section and the SPECIFIC USE RESTRICTIONS section of the label.
NOTE: Some varieties or inbred lines of onions may be more susceptible to Galigan H2O. Care should be taken to insure that the particular onion variety or line being grown is tolerant to Galigan H2O. It is suggested that all onion varieties or lines be tested in limited areas to ensure an adequate level of crop tolerance prior to an application for postemergence weed control.
Northeastern States (Connecticut, Maine, Massachusetts, New Hampshire, New Jersey, New York, Rhode Island, And Vermont)
Galigan H2O is recommended for postemergence control at a maximum use rate of 1 fluid ounce (0.03 lb. active) per acre when applied postemergence to seeded onions that have at least four (4) true leaves. Multiple treatments at this rate may be applied. Do not apply more than 1 pint (0.5 lb. active) per broadcast acre of Galigan H2O as a result of multiple applications in one season.
TIMING AND METHOD OF APPLICATION
For best postemergence control of susceptible weeds, apply when the weeds are in the 2- to 4-leaf stage. Application of Galigan H2O after the weeds exceed the maximum leaf stage may result in reduced weed control. More than one postemergence application may be necessary to control subsequent weed flushes.
Galigan H2O should be thoroughly mixed with clean water at recommended concentrations and applied in a minimum of 40 gallons of water per acre. Use conventional ground spray equipment with flat fan spray nozzles at 20 to 40 psi. Do not exceed 40 psi. Accurately calibrate spray equipment prior to each use. Thoroughly flush the spray equipment (tank, hose, pump, boom) with water before and after each use. Residual Galigan H2O remaining in the spray equipment may damage other crops.
CHEMIGATION: For application using sprinkler irrigation (solid set or portable lateral) systems, apply specified dosage of Galigan H2O per acre as described above. Follow all directions given in section of the label entitled APPLICATION THROUGH IRRIGATION SYSTEMS – CHEMIGATION when making applications using irrigation systems.
DO NOT APPLY WHEN WEATHER CONDITIONS FAVOR DRIFT. AVOID DRIFT TO ALL NON-TARGET AREAS. GALIGAN H2O IS PHYTOTOXIC TO PLANT FOLIAGE.
SPECIFIC USE RESTRICTIONS
In addition to the following, also observe GENERAL USE RESTRICTIONS listed elsewhere on the label.
- In all states, do not start spraying until the onions have reached the minimum leaf stage specified in the DOSAGE section of the label. Applications made prior to recommended onion development stage may result in serious injury and are not recommended.
- Do not apply more than a total of 1 pint (0.5 lb. active) per acre of Galigan H2O during one use season.
- Do not apply within 60 days of harvest.
- Do not mix Galigan H2O with oils, surfactants, liquid fertilizers, or other pesticides except as specified on the Galigan H2O label or other supplemental labeling.
- Do not apply to onion plants that are under stress due to drought, flooding, excessive fertilizer or soil salts, wind injury, hail, frost damage, injury from previously applied pesticides, or injury due to insects or diseases.
- Pigweed, Prostrate; Pigweed, Redroot; Purslane, Common: Specified weeds controlled at rates recommended for use in Northeastern states (see DOSAGE section).
