General 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.

Limitations, Restrictions, and Exceptions


General Information

Galigan H2O is a selective herbicide for postemergence and preemergence control of certain broadleaf weeds in jojoba. Galigan H2O should be postdirected to the base of the jojoba plant to avoid possible phytotoxicity to the jojoba foliage. Over-the-top applications may exhibit burning, crinkling, or bronzing of jojoba foliage, particularly to the youngest leaves, flowers, or buds present at the time of application.


Galigan H2O is recommended for postemergence and preemergence control of susceptible seedling weeds (up to 12 inches in height) at 3 pints (1.5 lbs. active) per broadcast acre. For optimum residual control, apply during the fall or winter. For early postemergence control of susceptible seedling weeds (less than 8 inches in height), apply Galigan H2O at a rate of 2 pints (10 lb. active) per broadcast acre.


Apply the first application of Galigan H2O after jojoba plants have grown to a minimum 6-inch height or greater. Additional applications should be applied as needed for post and preemergence weed control. Weed height should not exceed 12 inches or unsatisfactory weed control may result.

Galigan H2O should be applied in a minimum spray volume of 40 gallons of water per acre depending upon density of emerged weeds. Spray volume should be increased as weed height and density increase. Use a low-pressure sprayer equipped with flat fan nozzles. Spray equipment should be calibrated carefully before each use.


In addition to the following, also observe GENERAL USE RESTRICTIONS listed elsewhere on the label.

- Avoid direct spray or drift contact of Galigan H2O with jojoba flowers or buds as severe injury may result.

- Do not apply more than 3 pints (1.5 lbs. active) per broadcast acre in a single application nor more than 3 pints (1.5 lbs. active) per acre per year.


- Groundsel, Common; Pigweed, Redroot: Highest rate may be required for acceptable postemergence control.

- Filaree, Broadleaf; Filaree, Redstem; Filaree, Whitestem: Galigan H2O at the 3 pint rate (1.5 lbs. active) will provide control of filaree not exceeding the 4-inch stage.

Applications to filaree beyond the 4-inch stage may result in partial control.
