TREE AND VINE CROPS - SELECTIVE EQUIPMENT - PREEMERGENCE
Galigan Slapshot is a postemergent, systematic herbicide with residual preemergence herbicidal activity for the control or suppression of annual broadleaf and grasses in fallow systems and in dormant tree and vine crops. It may be applied through most sprayers after dilution and thorough mixing with water or other carriers according to the label instructions.
To maximize the preemegence herbicidal activity of Galigan Slapshot herbicide, 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. Within 3 to 4 weeks after application, at least one-quarter inch (1/4 inch) of irrigation should be applied to treated area if this amount of rainfall does not occur within this time period. The best results froms Galigan Slapshot herbicide are from applications to established beds or soil surfaces that are left undisturbed during the time 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 Slapshot. Length of residual activity is related to the rate of product used with higher rates resulting in longer residual control.
Time to Symptoms: Galigan Slaspshot moves through the plant from the pointof contact with foliage and into the root system. Visible effects on most annual weeds occur in 2 to 5 days, but on most perennial weeds may not occur for 7 days or more. Extremely cool or cloudy weather following treatment may slow activity of this product and delay development f visual symptoms. Visible effects are a gradual wilting, yellowing/browning of the plant which advances to complete browning of the above-ground growth and deterioration of underground plants parts.
Stage of Weeds: Weeds are generally easier to control when they are small. Refer to the \"Annual Weeds Rate Table\" for rate and size recommendations for specific weeds.
Always use the higher rate of this product per acre within the recommended range when weed populations are heavy or dense or weeds are growing in an uncultivated area.
Do not treat weeds under poor growing conditions such as drought stress, disease or insect damage, as reduced weed control may occur.
Reduced results may also occur when treating weeds heavily covered with dust.
Reduced control may result when applications are made to annual or perennial weeds that have been moved, grazed or cut, and have been allowed to regrow to the recommneded stage for treatment.
Rainfastness: Hravily rainfall soon after application may wash this product off of the foliage and a repeat application may be required for adequate control. Do not exceeds the maximum labeled rate per year.
Spray Coverage: For best results, spray coverage should be uniform and complete. Use higher volumes to assure adequate coverage in high densities of emerged weeds. Do not spray weeds foliage to the point of runoff.
TYPES OF APPLICATION
AERIAL SPRAY EQUIPMENT
Use the recommended rates of this herbicide in 3 to 15 gallons of water per acre unless otherwise specified on the label. Ensure uniform application. To avoid streaked, uneven, or overlapped application, use appropriate marking devices.
GROUND BROADCAST SPRAY EQUIPMENT
Use the recommended rates of this product in 3 to 40 gallons of water per acre as broadcast spray unless otherwise specified. As density of weeds increases, spray volume should be increased within recommended range to ensure complete coverage. Carefully select proper nozzles to avoid spraying a fine mist. For best results with ground application equipment, use flat spray nozzles. Check for even distribution of spray droplets.
This product may be used in ground injection spray systems. It may be used as a liquid concentrate or diluted prior to injectiing into the spray stream. Do not mix this product with the concentrate of other product when using injection system.
HAND-HELD OR HIGH-VOLUME SPRAY EQUIPMENT
Apply to foliage of vegetation to be controlled. For applications made on a spray-to-wet basis, spray coverage should be uniform and complete. Do not spray to the point of runoff. Use coarse sprays only. For recommended rates and timing, refer to the “POSTEMERGENCE ANNUAL WEEDS TABLE (Table 1)” section of this product label.
SELECTIVE SPRAY EQUIPMENT
This product may be applied through recirculating spray systems, shielded and hooded sprayers, and wiper applicators after dilution and thorough mixing with water to listed weeds growing in any noncrop site specified on the label. In cropping systems, hooded sprayers, shileded sprayers, and wipers may be used in row middles (in between rows of crop plants) where any dripping or leaking will not contact crop foliage, when listed under “TYPES OF APPLICATION” in the crop section of this product’s labeling. Such equipment must be capable of preventing all crop contact with herbicide solutions and operated without leakage of spray mists or dripping onto crop. Wipers over-the-top of crops may be used only when specifically recommended in this products labeling.
Use Precautions and Restrictions when using Selective Spray Equipment:
- AVOID CONTACT OF HERBICIDEWITH DESIRABLE VEGETATION. Contact of herbicide solution should be adjusted so that the lowest spray or wiper contact point is at least 2 inches above the desirable vegetation. Droplets, mist, foam or splatter of the herbicide solution settling on desirable vegetation may result in discoloration, stunting or destruction.
- Applications made above the crops should be made when the weeds are a minimum of 6 inches above the desirable vegetation. Better results may be obtained when more of the weed is exposed to the herbicide solution. Weeds not contacted by the herbicide solution will not be controlled. This may occur in dense clumps, severe infestations or when the height of the weeds varies so that not all weeds are contacted. In these instances, repeat treatment may be necessary. Always follow the maximum application rate under each specific crop section
Recirculating Spray System:
A recirculating spray system directs the spray solution onto weeds growing above desirable vegetation, while spray solution not intercepted by weeds is collected and returned to the spray tank for reuse.
Shielded and Hooded Applicators:
When applied under the conditions described in the following paragraphs for shielded and hooded applications, this product at recommended rates will control those weeds listed in the “POSTEMERGENCE ANNUAL WEEDS TABLE (Table 1)” section of the label. A hooded sprayer is a type of shielded applicator where the spray pattern is fully enclosed including top, sides, front and back, thereby shielding the crop from the spray solution. Keep shields on these sprayers adjusted to protect desirable vegetation. When applying to crops grown on raised beds, ensure that the hood is designed to completely enclose the spray solution. If necessary, extend the front and rear flaps of the hoods to reach the ground in deep furrows. EXTREME CARE MUST BE EXERCISED TO AVOID CONTACT OF HERBICIDE WITH DESIRABLE VEGETATION.
This equipment must be set up and operated in a manner that avoids bouncing or raising the hoods off the ground in any way. If the hoods are raised, spray particles may escape and come into contact with the crop, causing damage or destruction of the crop. Avoid operation on rough or sloping ground where the spray hoods might be raised off the ground.
Use hoods designed to minimize excessive dripping or run-off down the inside of the hoods. A single, low pressure/low drift flat-fan with an 80 to 95 degree spray angle positioned at the top center of the hoods is recommended. Spray volume should be 20-30 gallons per acre.
These procedures will reduce the potential for crop injury:
- The spray hoods must be operated on the ground or skimming across the ground.
- Leave at least an 8 inch untreated strip over the drill row. For example, if the crop width is 38 inches, the maximum width of the spray hood should be 30 inches.
- Maximum tractor speed: 5 miles per hour to avoid bouncing of the spray hoods.
- Maximum wind speed: 10 miles per hour.
- Use low-drift nozzles that provides uniform coverage within the treated area.
Crop injury may occur when the foliage of treated weeds comes into direct with weeds to be treated. Droplets, mist, foam or splatter of the herbicides solution may contact the crop and cause discoloration, stunting or destruction.
When applied under the conditions described in the following paragraphs, this product CONTROLS weeds including volunteer corn, Texas panicum, common rye, shattercane, sicklepod, spanishneedles an bristly starbur; and SUPPRESSES many weeds including Florida beggarweed, Bermudagrass, hemp dogbane, dogfennel, guineagrass, milkweed, silverleaf nightshade, redroot pigweed, giant ragweed, smutgrass, sunflower, Canada thistle, musk thistle, vaseygrass, velvetleaf.
Wiper Applicators are devices that physically wipe appropriate amounts of this product directly onto the weed.
Equipment must be designed, maintained and operated to prevent the herbicide solution from contacting desirable vegetation. Operate this equipment at ground speeds no greater than 5 miles per hour. Performance may be improved by reducing speed in areas of heavy weed infestations to ensure adequate wiper saturation. Better results may be obtained if two applications are made in opposite directions.
Avoid leakage or dripping onto desirable vegetation. Adjust height of applicator to ensure adequate contact with weeds. Keep wiping surfaces clean. Be aware that, on slopping ground, the herbicide solution may migrate, causing dripping on the lower end and drying of the wicks on the upper end of a wiper applicator. Do not use wiper equipment when weeds are wet. Mix only the amount of solution to be used during a 1-day period, as reduced activity may result from use of leflover solutions. Clean wiper parts immediately after using this product by thoroughly flushing with water. Do not add surfactant to the herbicide solution.
TREE AND VINE CROPS
NOTE: THIS DIRECTIONS APPLY TO ALL CITRUS (NON-BEARING ONLY), TREE FRUITS, TREE NUTS AND VINE CROPS. SEE THE INDI-VIDUAL SECTIONS UNDER THIS HEADING FOR INSTRUCTIONS, PRECAUTIONS, AND RESTRICTIONS FOR SPECIFIC CROPS.
Timing of Application: This product should be applied postemergence to vigorously growing weeds when they have reached the recommended size given in the “POSTEMERGENCE ANNUAL WEEDS TABLE (Table 1)” during the DORMANT season of the crop. Application should be delayed until maximum emergence of the target weeds, but before weeds exceed the maximum size recommended. When applied at recommended rates, Galigan Slapshot will also offer preemergence herbicidal activity against selected weeds as they are emerging. These are listed in the “PREEMERGENCE ANNUAL WEEDS TABLE (Table 2)”. The length of residual control will depend on the Galigan Slapshot rate used. In general, the higher the rate used, the greater the length of residual control. For annual weeds, allow 1 day after treatment before tillage.
Reduced control may result if treatments are made during poor growing conditions such as drought stress, disease, or insect damage, or if weeds have been mowed, grazed, or cut. Heavy dust on foliage or an overstory canopy covering tar-geted weeds may also reduce control. Heavy rainfall or irrigation soon after application may wash this product off the foliage and a repeat treatment may be required for adequate control.
Types of Applications: General weed control, middles (between rows of trees), strips (in row of trees), selective equipment (except kiwi) in DORMANT tree and vine crops.
Galigan Slapshot is effective as a preemergence and/or postemergence herbicide when used alone or in recommended combinations for the control of certain annual broadleaf weeds in certain bearing and nonbearing tree fruit, nut, or vine plantings as listed in the “TREE FRUITS, TREE NUTS, and CITRUS (Nonbearing Only)(SPECIFIC SECTION)” below. The most effective postemergence weed control is achieved when Galigan Slapshot herbicide is applied to seedling weeds.
For increased preemergence control of susceptible weeds in certain tree fruit, nut, or vine plantings, a tank mixture of Galigan Slapshot herbicide with napropamide (Devrinol), diuron (Karmex), pronamide (KERB), simazine, norflurazon (Solicam), or oryzalin (Surflan) can be applied. Check individual product labels to determine suitability
and use rates for various crops.
This product may be applied in middles, strips and for weed control in established nonbearing citrus groves, tree fruit and tree nut orchards, and vineyards. This product may also be used for site preparation prior to transplanting these crops. For weeds controlled, refer to the “POSTEMERGENCE ANNUAL WEEDS TABLE (Table 1)”. Single
applications cannot exceed 6 pints of Galigan Slapshot herbicide per acre per year. Higher use rates will result in longer residual control. Allow a minimum of 3 days between application and transplanting. Applications may be made with boom equipment, CDA (Controlled Droplet Applicators), shielded sprayers, hand-held and high-volume wands, lances, orchard guns or with wiper applicator equipment, except as directed.
Spray Volume: A minimum of 40 gallons of spray solution should be applied per acre.
