ONION SEEDED - WESTERN 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.
Galigan H2O is a selective herbicide for postemergence application to directseeded and transplanted onions for early postemergence control of certain annual broadleaf and grass 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. On onion transplants, spray as soon before or after transplanting as practical. 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.
Western States (Arizona, California, Colorado, Idaho, Nevada, New Mexico, Oregon, Texas, Utah, and Washington)
Galigan H2O is recommended for postemergence control at 0.25 pint to 0.5 pint (0.12 to 0.25 lb. active) per acre when applied postemergence to onions that have at least two (2) true leaves. Multiple treatments at the aforementioned rates 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. Applications may be made in a minimum of 40 gallons of water per acre. The preharvest interval is 45 days.
Sprinkler Chemigation: For application using sprinkler irrigation (solid set or portable lateral systems), apply specified dosage of Galigan H2O per acre as described in this section. Follow all directions given in the section entitled APPLICATION THROUGH IRRIGATION SYSTEMS – CHEMIGATION when making applications using sprinkler irrigation systems.
SPECIFIC USE RESTRICTIONS
In addition to the following, also observe GENERAL USE RESTRICTIONS listed elsewhere on the label.
- In all states except Northeastern states, do not start spraying until the onions (direct-seeded) have two (2) fully developed true leaves. In the Northeastern states (Connecticut, Maine, Massachusetts, New Hampshire, New Jersey, New York, Rhode Island, Vermont), do not start spraying until the onions (direct-seeded) have three (3) fully developed true leaves. Applications made prior to the 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 45 days of harvest.
- Use only on dry bulb onions.
- Do not apply to onions grown for seed except as specified below or on other approved supplemental labeling.
- Tank mixtures of Galigan H2O with oils, surfactants, liquid fertilizers, or other pesticides may result in enhanced crop response/injury and are the responsibility of the user.
- Do not apply Galigan H2O preemergence to direct-seeded onions.
- Do not apply to onion plants that are under stress due to drought, flooding, excessive fertilizer or soil salts, storage conditions, wind injury, hail, frost damage, injury from previously applied pesticides, or injury due to insects, nematodes, or diseases.
- Eveningprimrose, Cutleaf; Pigweed, Redroot; Purslane, Common: Weeds controlled when applied as a pre-transplant application. In addition, Galigan H2O at the rate of 1/2 to 1 pint per acre will provide control/suppression of carpetweed, Pennsylvania smartweed, galinsoga, common lambsquarters, and wild mustard. Applications of Galigan H2O to muck soils may result in partial control or suppression of the weeds listed.
- Pigweed, Prostrate; Pigweed, Redroot; Purslane, Common; Shepherdspurse: Specific weeds controlled at rates recommended for use in Northeastern states (see DOSAGE section).
