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 effective as a preemergence herbicide when used alone for the control of certain annual broadleaf weeds in garbanzo beans. Preemergence control is most effective when spray is applied to clean, weed-free soil surfaces. Seedling weeds are controlled as they come in contact with soil-applied herbicide during emergence. Timely cultivations will usually assist in weed control.

Garbanzo beans are tolerant to preemergence applications of Galigan H2O, however, under certain conditions, Galigan H2O can cause severe but temporary crop injury. Heavy splashing rain shortly after crop emergence or wet soil conditions during early growth stages can produce leaf cupping, crinkling, stunting, or defoliation of the garbanzo seedlings. When injury occurs, it is often limited to the first few leaves that develop shortly after crop plants emerge from the soil. Delays in crop development and/or maturity may result. Garbanzo beans do recover from this injury with little to no impact on yield.


Galigan H2O is recommended for preemergence control of susceptible winter annual broadleaf weeds at 0.5 pint (0.25 lb. active) per broadcast acre.


Galigan H2O used alone at recommended dosages provides preemergence control of the broadleaf weeds listed.


As a preemergence application, apply in a minimum of 20 gallons of water per acre. Use conventional ground spray equipment to make a single broadcast application after planting but prior to weed and crop emergence with flat fan or hollow cone 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.

- Do not apply more than 0.5 pint (0.25 lb. active) per broadcast acre of Galigan H2O in a single application.

- Do not feed beans, vines, or hay.
