GRAPES NON DORMANT - POSTEMERGENCE
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.
GRAPES (CALIFORNIA ONLY) NON-DORMANT APPLICATION
Galigan H2O may be used for the control/suppression of susceptible broad leaf weed species in non-dormant grapes (raisin and wine grapes only) when applied either as a directed ground spray application or for supplemental preemergence weed control through low-volume sprinkler (microsprinkler) or drip (trickle) irrigation systems. (Galigan H2O can be applied to all grapes (raisin, table, wine) when applied as a dormant application as specified above.) The total amount of Galigan H2O applied during one season (from completion of final harvest through dormancy to non-dormant use covered by this section) cannot exceed a total of 3 pints (1.5 lbs.active) per acre as a result of multiple applications in any given area (broadcast, banded, or within the wetted area of the low-volume sprinkler or drip irrigation systems).
CROP TOLERANCE INFORMATION
The use of Galigan H2O may in some instances result in varying degrees of injury to non-dormant grapes. Grape foliage will typically exhibit injury symptoms from direct or indirect (spray drift, soil contact) exposure to Galigan H2O. This injury may result in leaf necrosis, reddening of the foliage, leaf cupping, or crinkling of the crop. The grape plant continues to grow normally. Immature, expanding leaves at the time of contact with Galigan H2O are the most susceptible to foliage injury. Grapes may exhibit some small blemishes (spots or flicks) on the fruit.
DOSAGE AND APPLICATION TIMING
Applications can be made to non-dormant grapes during the period between the completion of bloom up through 14 days prior to harvest.
Do not apply more than 3 pints (1.5 lbs. active) per broadcast acre per season as a result of multiple applications made during the dormant and non-dormant season (up to 14 days prior to harvest).
WEEDS CONTROLLED / SUPPRESSED POSTEMERGENCE (weeds up to 4 inches high) For postemergence control/suppression, apply to susceptible weed seedlings up to 4 inches in height. Repeat applications may be required. Applications to weeds beyond this 4-inch stage or at reduced use rates will result in reduced herbicidal activity. For enhanced postemergence activity on certain grassy and broadleaf weeds, a tank mixture of Galigan H2O with either paraquat or glyphosate can be used when applied as a directed spray with ground application equipment.
METHOD OF APPLICATION
GROUND APPLICATION: Galigan H2O should be thoroughly mixed with clean water at recommended concentrations and applied in a minimum of 20 gallons of water per acre (a minimum of 10 gallons per acre for tank mixes with glyphosate). Use higher volumes to ensure adequate coverage in high densities of emerged weeds or heavy trash. Best preemergence results are achieved when spray is applied to a relatively weed-free established berm or soil surface. Galigan H2O should be directed to the soil and the base of vines. Use a low-pressure sprayer equipped with a breakaway boom and flat fan nozzles. An off-center (OC) nozzle positioned at the end of the boom may be desired. Spray equipment should be calibrated carefully before each use.
See SPECIFIC USE RESTRICTIONS for Galigan H2O herbicide application on non-dormant vine plantings. Thoroughly flush the spray equipment (tank, hose, pump, boom) with water before and after each use. Residual Galigan H2O remaining in spray equipment may damage other crops. AVOID DRIFT TO ALL OTHER CROPS AND NON-TARGET AREAS. DO NOT APPLY WHEN EATHER CONDITIONS FAVOR DRIFT. GALIGAN H2O HERBICIDE IS PHYTOTOXIC TO PLANT FOLIAGE.
CHEMIGATION APPLICATION: Galigan H2O may be applied using sprinkler [low-volume (microsprinkler)] and drip (trickle) irrigation systems designed to distribute irrigation water beneath the vine canopy. The application of Galigan H2O is intended to supplement the preemergence weed control requirements of a broadcast (or directed) weed control program where weed emergence is anticipated within the wetted area of a low-volume sprinkler (microsprinkler) or drip (trickle) irrigation system. Applications should be made prior to weed emergence since postemergence activity will be inconsistent due to partial coverage. Apply the specified dosage of Galigan H2O per acre as described in DOSAGE AND APPLICATION TIMING section above for non-dormant grapes. Meter Galigan H2O at a continuous uniform rate during the middle 1/3 of the irrigation period to allow for uniform distribution to the soil surface. For best results, Galigan H2O should be uniformly positioned across the wetted area to help reduce the RING EFFECT of weed escapes as other products begin to break down around the emitter. Continue irrigation during the final 1/3 of the irrigation period to insure proper flushing of the irrigation system. Follow all directions given in the section entitled APPLICATION THROUGH IRRIGATION SYSTEMS – CHEMIGATION when making applications using sprinkler irrigation systems. Do not allow treated irrigation water to contact the fruit or foliage.
