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.

Limitations, Restrictions, and Exceptions


General Information

Galigan H2O is effective as a preemergence herbicide when used alone for the control of certain annual broadleaf weeds in bearing and non-bearing cacao plantings. Preemergence control is most effective when spray is applied to clean, weed-free soil surfaces. Treated berms or soil surfaces should not be disked or disturbed in any manner as the herbicidal effectiveness of Galigan H2O may be decreased. Seedling weeds are controlled as they come in contact with soil-applied herbicides during emergence.


Galigan H2O herbicide is recommended for preemergence and postemergence control of susceptible weeds at 1 to 4 pints (0.5 to 2.0 lbs. active) per broadcast acre when directed to the orchard floor beneath cacao plants or at a dosage of up to 2 pints per acre as a pre-transplant application. For directed spray applications, cacao transplants must be healthy and of suitable size for field transplanting. Avoid spray contact with cacao foliage as injury may result. Dosages listed are for broadcast application. See label to determine the amount of product when using band application.


DO NOT APPLY PREPLANT OR PREEMERGENCE TO DIRECT-SEEDED CACAO. GALIGAN H2O MAY BE APPLIED TO ESTABLISHED CACAO OR APPLIED PRE-TRANSPLANT OR TO RECENTLY TRANSPLANTED CACAO. Treatments should only be applied to healthy cacao stock (as determined by standard commercial growing practices). Care must be taken to prevent direct spray contact with foliage. Cacao foliage receiving accidental spray or drift may be injured. As a preemergence or postemergence treatment to weeds, apply in a minimum of 15 gallons of water per acre. Use higher volumes to assure adequate coverage in high densities of emerged weeds or heavy trash. Galigan H2O should be directed to the soil and the base of the tree. Use of a low-pressure sprayer equipped with a breakaway boom and flat fan or off-center (OC) nozzles is recommended. Spray shields are suggested for use in young trees. Spray equipment should be calibrated carefully before each use.


In addition to the following, also observe the GENERAL USE RESTRICTIONS listed at the beginning of the label.

- Do not apply more than 4 pints (2.0 lbs. active) per broadcast acre of Galigan H2O in a single application or 12 pints (6.0 lbs. active) per broadcast acre per year.

- Do not apply Galigan H2O within one (1) day of harvest.

- Direct spray toward the base of the trees. Avoid spray contact with foliage.

- Do not apply preplant or preemergence to direct-seeded cacao.
