ARTICHOKES (GLOBE) - PREEMERGENCE
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.
Galigan H2O is an effective herbicide for postemergence and preemergence control of listed broadleaf weeds in artichokes. Galigan H2O should be directed toward the winter ditch, levees, or flat rows between the artichoke rows. Artichoke fronds receiving accidental spray or drift will be injured. Over-the-top applications may exhibit severe injury to the foliage and flower bud and are not recommended.
Galigan H2O is recommended as a post-directed application at 2 to 3 pints (1 to 1.5 lb. active) per acre. Optimum control is achieved when two applications of Galigan H2O are applied. The initial application should be made to susceptible weed seedlings (up to 8-leaf stage). It is recommended that a second application be made 8 to 10 weeks later. Good results may be achieved when a single application of 3 pints (1.5 lb. active) of Galigan H2O is applied to susceptible weed seedlings (up to 8-leaf stage). Do not apply more than 3 pints (1.5 lb. active) of Galigan H2O per treated acre per season as a result of a single application or multiple applications. Do not apply within 5 days of harvest.
TIMING AND METHOD OF APPLICATION
Treatments should be made after completion of the ditching operation. Galigan H2O should be applied in a minimum 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. Spray should be directed towards the winter ditch, levees, or flat rows between the artichoke rows. ARTICHOKE FRONDS RECEIVING ACCIDENTAL SPRAY OR DRIFT WILL BE INJURED.
SPECIFIC USE RESTRICTIONS:
In addition to the following, also observe GENERAL USE RESTRICTIONS listed at the beginning of the label.
- Do not apply more than 3 pints (1.5 lb. active) of Galigan H2O per treated acre per season as a result of a single application or multiple applications.
- Do not apply Galigan H2O within 5 days of harvest.
- Avoid direct spray or drift contact of Galigan H2O with artichoke flowers or buds as severe injury may result.
- Do not apply Galigan H2O to artichoke plantings within 60 days after cutting back or transplanting.
