MINT (PEPPERMINT) - WESTERN OREGON
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.
MINT (SPEARMINT, PEPPERMINT)
Galigan H2O is a selective herbicide for the control of certain annual grasses and broadleaf weeds in spearmint and peppermint grown in California, Idaho, Montana, Nevada, Oregon, South Dakota, Utah, and Washington. Applications should only be made to spearmint and peppermint during the dormant season.
METHOD OF APPLICATION
Application must be made prior to new spring growth or severe crop injury may result. Galigan H2O should be thoroughly mixed with clean water at recommended concentration and applied at 20 to 40 psi in 20 to 40 gallons of water per acre.
When Galigan H2O is applied as a dormant application at recommended dosages in spearmint and peppermint, the annual weeds are controlled.
PEPPERMINT (WILLAMETTE VALLEY)
Apply 1 to 1.5 pints (0.5 to 0.75 lb. active) of Galigan H2O from November to February to dormant peppermint only. Treatments in January or February generally provide better residual preemergence control of annual broadleaf weeds. Full season weed control should not be expected from this treatment. Make only application per season using this regime. Application may be made in a minimum of 20 gallons of water per acre.
DO NOT APPLY GALIGAN H2O IN THE WILLAMETTE VALLEY TO MINT THAT HAS BEEN PLOWED.
SPECIFIC USE RESTRICTIONS
In addition to the following, also observe GENERAL USE RESTRICTIONS listed elsewhere on the label.
- Do not apply more than one application of Galigan H2O per season.
- Apply Galigan H2O only to healthy spearmint and peppermint. Do not apply to spearmint or peppermint that has been weakened by disease, drought, flooding, excessive fertilizer, soil salts, previously applied pesticides, nematodes, soil insects, or winter injury as severe injury may result.
Bluegrass, Annual; Oats, Wild; Ryegrass, Italian: Control of annual grasses is best obtained when Galigan H2O is applied prior to emergence. Postemergence control of winter annual grasses is generally unsatisfactory if applications are made after the 1- to 2-leaf stage.
