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 may be used for preemergence and post-directed application to dryland taro for the control of certain broadleaf weeds.
NOTE: Dryland taro is defined as a taro grown without irrigation or by using irrigation practices that do not result in runoff, irrigation return flow, or other loss of irrigation water from the production area. If irrigation is used, the water applied shall not exceed the field capacity of the soil.
Occasionally, after the use of Galigan H2O, a spotting, crinkling, or flecking may appear on the leaves of the taro. Leaves that receive direct or indirect (drift) spray contact will be injured.
Do not use Galigan H2O on taro plantings that are weak or under stress due to temperature, disease, fertilizer, nematodes, insects, pesticides, drought, or excessive moisture.
Apply Galigan H2O at a rate of 1 pint (0.5 lb. active) per broadcast acre as a single preemergence application within one week after transplanting (and prior to emergence) of the taro. Galigan H2O is also recommended as a post-direct application of 0.5 pint (0.25 lb. active) per acre. Effective control of succulent weed seedlings in the 2- to 3-leaf stage can usually be obtained. Do not apply more than 0.5 pint (0.25 lb. active) of Galigan H2O per acre in a single post-direct application or more than 1 pint (0.5 lb. active) per broadcast acre per season as a result of multiple post-direct applications. Refer to the label for Band Application.
Galigan H2O will provide preemergence and postemergence control of the weeds listed when used at the recommended dosages. Applications to weeds beyond the 3-leaf stage may result in partial control.
TIMING AND METHOD OF APPLICATION
Galigan H2O should be thoroughly mixed with clean water at recommended concentrations and applied in a minimum of 15 gallons of water per acre. When applied preemergence, use conventional ground spray equipment with flat fan nozzles at 20 to 40 psi. Accurately calibrate spray equipment prior to each use.
When applied as a post-direct spray, sprays must be directed to the base of the taro plant. Accurate, uniform placement of Galigan H2O is essential for effective weed control and to minimize crop injury. Taro foliage receiving accidental spray or drift will be injured. Galigan H2O must be applied using rigid precision ground sprayer equipment. As a directed postemergence application, Galigan H2O should be applied at 20 to 25 psi using 20 to 40 gallons of spray on a broadcast acre basis. Do not exceed 25 psi.
SPECIFIC USE RESTRICTIONS
In addition to the following, also observe GENERAL USE RESTRICTIONS listed elsewhere on the label.
- Do not apply more than 1 pint (0.5 lb. active) of Galigan H2O per broadcast acre as a single preemergence application.
- Do not apply more than 0.5 pint (0.25 lb. active) of Galigan H2O per broadcast acre in a single post-direct spray or more than 1 pint (0.5 lb. active) per broadcast acre per season as a result of multiple post-direct applications.
- Do not apply more than 2 pints (1.0 lb. active) of Galigan H2O per broadcast acre per season as a result of preemergence and post-direct applications.
- Do not apply Galigan H2O within 6 months of harvest of taro (corms, leaves).
- For use only on dryland taro grown in Hawaii. (Dryland taro is defined as taro grown without irrigation or by using irrigation practices that do not result in run-off, irrigation return flow, or other loss of irrigation water from the production area. If irrigation is used, the water applied shall not exceed the field capacity of the soil).
