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.

General Information

Galigan H2O is recommended for postemergence and preemergence control of certain broadleaf weeds in non-crop areas.

WEEDS CONTROLLED POSTEMERGENCE (weeds up to 4 inches high) Apply 1 to 4 pints (0.5 to 2.0 lbs. active) of Galigan H2O per broadcast acre. The lower rate in the rate range is recommended for control of susceptible weeds in the early postemergence stage, less than 4 inches in height. The higher rate (2.0 lbs. active) should be used for weeds up to 12 inches in height. Applications to weeds beyond the 4-inch stage may result in partial control.


Galigan H2O should be applied in a minimum of 40 gallons of water per acre. Best preemergence results are achieved when spray is applied to a relatively weed free soil surface. The volume of water used should be increased as the weeds become taller and more dense. Use a low-pressure sprayer equipped with flat fan nozzles. Spray equipment should be calibrated carefully before each use.


For preemergence control of susceptible grassy and broadleaf weeds, a tank mixture of Galigan H2O with diuron or simazine can be applied. Apply at the recommended rates and growth stages to susceptible weed species in a manner described on the respective labels.


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

- Do not feed or allow animals to graze on any areas treated with Galigan H2O herbicide.

- Do not apply more than 4 pints (2.0 lbs. active) in a single application.
