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 preemergence use (by air, ground, or sprinkler application), post-direct use when applied by ground equipment, or postemergence (over-the-top) application when applied via sprinkler irrigation for control of certain broadleaf and grass weeds in garlic in California.
Chemigation: If Galigan H2O is to be applied via sprinkler irrigation, follow the method of application directions listed for sprinkler chemigation. For application using sprinkler (solid set or portable lateral) irrigation systems, apply specified dosage of Galigan H2O per acre as described below. Follow all directions given in the APPLICATION THROUGH IRRIGATION SYSTEMS – CHEMIGATION section of the label when making applications using sprinkler irrigation systems.
Transplanted garlic is most tolerant of a postemergence application immediately after transplanting. For all states except the Northeastern states listed under the DOSAGE – SEEDED GARLIC section, an application of up to 1 pint (0.5 lb. active) per acre within two days after transplanting may be made. If less than 1.0 pint per acre are applied, a second application can be made two weeks or more after transplanting. Do not exceed the maximum use rate of 1 pint (0.5 lb. active) per broadcast acre of Galigan H2O as a result of multiple applications in one season.
For transplanted garlic in the Northeastern states, apply the same rates listed in the DOSAGE – SEEDED GARLIC section within two days after transplanting.
Dosages listed are for broadcast application. For banded application, the amount of Galigan H2O used per acre should be reduced according to the formula listed on the label.
Refer to the label for Band Applications.
Galigan H2O will provide postemergence control of the weeds listed when applied at the recommended dosage and leaf stage (2 to 4 leaves).
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 concentration 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. Accurately calibrate spray equipment prior to each use. Avoid drift to all other crops and non-target areas. Thoroughly flush the spray equipment (tank, hose, pump, boom) with water before and after each use. Residual Galigan H2O remaining in spray equipment may damage other crops.
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 garlic (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 garlic (direct-seeded) have three (3) fully developed true leaves. Applications made prior to the recommended garlic 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.
- Use only on dry bulb garlic.
- Do not apply to garlic grown for seed.
- Tank mixtures of Galigan H2O with oils, surfactants, liquid fertilizers, or pesticides may result in enhanced crop response-injury and are the responsibility of the user.
- Do not apply Galigan H2O preemergence to direct-seeded garlic except California.
- Do not apply to garlic 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.
Pigweed, Prostrate; Pigweed, Redroot; Purslane, Common; Shepherdspurse: Specific weeds controlled at rates recommended for use in Northeastern States (see DOSAGE section).
