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 a selective herbicide that can be used for the control of certain annual broadleaf weeds in dormant spearmint and peppermint. Applications should be made prior to the emergence of spearmint and peppermint that is grown on muck soils. Applications made after the spearmint and peppermint emerge will result in severe injury. Applications to first year spearmint and peppermint should be made within four (4) days of planting (sprigging) to prevent excessive injury.


When Galigan H2O is applied at recommended dosages in spearmint and peppermint, the weeds listed are controlled.


Galigan H2O should be applied at a rate of 2 to 3 pints (1.0 to 1.5 lbs. active) per acre. When used postemergence (to the weeds) add an 80% active nonionic surfactant at the rate of one quart per 100 gallons of spray solution. Applications should be made before the weeds exceed four inches. It is important that applications of Galigan H2O herbicide be made prior to the emergence of the spearmint and peppermint. Galigan H2O herbicide should be thoroughly mixed with clean water at recommended concentrations and applied in 20 to 40 gallons of water per acre. Apply at 20 to 40 psi.


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

- Apply Galigan H2O only to spearmint and peppermint grown on muck soils (muck soils should have an organic matter of 20% or greater).

- Always apply Galigan H2O to healthy spearmint and peppermint. Do not apply Galigan H2O to spearmint or peppermint that has been weakened by disease, nematodes, soil insects, or winter injury, as severe injury may result.

- Do not apply Galigan H2O to spearmint or peppermint that has emerged.

- Applications of Galigan H2O to first-year spearmint or peppermint should be made within four (4) days of planting (sprigging).

- The use of any treated plants for feed or forage and the feeding or grazing of any treated area is prohibited.

- Do not make more than one application per season.
