PERENNIAL WEED CONTROL - FIELD BINDWEED
GENERAL PRODUCT INFORMATION
GLYFOS-SOLUBLE CONCENTRATE HERBICIDE is a water-soluble herbicide for non-selective weed control. GLYFOS-SOLUBLE CONCENTRATE HERBICIDE is applied as a foliar spray for the control of most herbaceous plants. It may be applied through most standard industrial or field type sprayers after dilution and thorough mixing with water in accordance with the booklet instructions.
GLYFOS-SOLUBLE CONCENTRATE HERBICIDE moves through the plant from the point of foliage contact into the root system. Visible effects on most annual weeds occur within 2 to 4 days, but on most perennial weeds may not occur until 7 to 10 days. Extremely cool or cloudy weather at treatment time may slow down the activity of this product and delay visible effects of control. Visible effects are a gradual wilting and yellowing of the plant which advances to complete browning of above ground growth and deterioration of underground plant parts.
Do not treat weeds under poor growing conditions such as drought stress, disease or insect damage, as reduced weed control may result. Reduced results may also occur when treating weeds heavily covered with dust.
GLYFOS-SOLUBLE CONCENTRATE HERBICIDE does not provide residual weed control. For subsequent residual weed control, apply a registered residual herbicide. Read and carefully observe cautionary statements and all other information appearing on the labels of all herbicides used. Heavy rainfall immediately after application may wash the chemical off the foliage and a repeat treatment may be required. Do not apply if rainfall is forecast for the time of application.
GENERAL APPLICATION NOTES
Results are best when weeds are actively-growing. If weeds have been mowed, allow to return to
recommended growth stage.
Delay application until vegetation has emerged to the stage described for the control of such vegetation under the ANNUAL and PERENNIAL WEED CONTROL charts of this booklet to provide adequate leaf surface to receive the spray. Unemerged plants arising from underground rhizomes or root stocks of perennials will not be affected by the spray and will continue to grow. For this reason best control of most perennial weeds is obtained when the treatment is made at the late growth stages approaching maturity. Always use higher rates of GLYFOS-SOLUBLE CONCENTRATE HERBICIDE per hectare within the recommended range when weed growth is heavy or dense or weeds are growing in an undisturbed (noncultivated) area.
Weed control may not be satisfactory if this product is applied to weeds growing under poor growing conditions such as drought, flooding, frost, high temperatures, disease or insect damage. Reduced results may also occur when treating weeds heavily covered with dust.
Heavy rainfall immediately after application may wash the product off the foliage and a repeat treatment may be required. Do not apply if rainfall is forecast for the time of application.
GLYFOS-SOLUBLE CONCENTRATE HERBICIDE should only be mixed with products recommended on the label. Do not mix with any surfactant, pesticide, herbicide oils or any other material other than water unless specified.
GLYFOS-SOLUBLE CONCENTRATE HERBICIDE controls many annual and perennial grasses, broadleaf weeds and woody brush and trees when applied as recommended and under the conditions described. For information on how to control specific weeds, including herbicide rate, refer to the ANNUAL WEED CONTROL and PERENNIAL WEED CONTROL charts of the label.
GROUND BOOM AND BOOMLESS SPRAYERS
Application: Use flat-fan nozzles in boom sprayers. To control perennial weeds, woody brush, and trees as listed, apply GLYFOS-SOLUBLE CONCENTRATE HERBICIDE in 50 to 300 L of water per hectare as a broadcast spray. Use no more than 275 kPa pressure.
To control annual weeds as listed, apply GLYFOS-SOLUBLE CONCENTRATE HERBICIDE in 50 L to 100 L of water per hectare as a broadcast spray. Use no more than 275 kPa pressure.
KNAPSACK SPRAYERS, HAND HELD & HIGH-VOLUME EQUIPMENT
High-volume spraying utilizes handguns or other suitable nozzle arrangements to apply a directed spray to weeds, woody brush, and trees. Use coarse sprays only.
Application: Spray coverage should be uniform and complete. Apply on a spray-to-wet basis. Do not spray to the point of runoff. Hand gun application should be properly directed to avoid spraying desirable plants.
For control of woody weeds, brush, and trees listed in the VEGETATION CONTROLLED lists, use the recommended rate of GLYFOS-SOLUBLE CONCENTRATE HERBICIDE in at least 200 L of water per hectare.
WIPER, WICK AND ROLLER EQUIPMENT
These applicators apply GLYFOS-SOLUBLE CONCENTRATE HERBICIDE solution directly onto the weeds by contacting the weed with an absorbent material containing the herbicide solution. Weeds should be a minimum of 15 cm above the desired vegetation to prevent contact of GLYFOS-SOLUBLE CONCENTRATE HERBICIDE with the desired vegetation.
Application: These applicators can be used to control weeds in:
- Industrial sites, tree plantings, and non-crop sites as specified.
- The following agricultural crops: apple, cherry, peach, pear and plum orchards, grape vineyards, soybeans, dry beans, strawberries, and cranberries (note: applications must be made before initial pod set in soybeans and dry beans).
The applicator should be adjusted so that the contact point of the wiper, roller, or wick is at least 5 cm above the desirable vegetation. Droplets or foam of the GLYFOS-SOLUBLE CONCENTRATE
HERBICIDE solution settling on desirable vegetation may result in discoloration, stunting or destruction. Best results are obtained when more of the weed is exposed to the herbicide solution. It is recommended that two applications be made in opposite directions, if possible.
Weeds not contacted will not be affected. This may occur in dense clumps, severe infestation, or when the height of the weeds varies so that not all weeds are contacted. In these instances, a repeat treatment may be necessary.
AVOID CONTACT WITH DESIRABLE VEGETATION
For mixing instructions refer to the label.
Directions for Use (for additional information see section on AERIAL APPLICATIONS: For
industrial rights-of-way only)
Apply only by fixed-wing and rotary aircraft equipment which has been functionally and operationally calibrated for the atmospheric conditions of the area and the application rates and conditions of the label. Ensure that the maximum boom width does not exceed 65% of the wing span. Nozzle type, size and orientation must be configured to deliver a droplet size VMD in the coarse (400-600 microns) or very coarse (600-1000) range. Label rates, conditions and precautions are product specific. Read and understand the entire label before opening this product. Apply only at the rate recommended for aerial application on the label. Where no rate for aerial application appears for the specific use, this product cannot be applied by any type of aerial equipment.
Ensure uniform application. To avoid streaked, uneven or overlapped application, use appropriate
marking devices. The use of a spotter plane is recommended.
AGRICULTURAL AND CROPLAND USES
The type of vegetation present and the use situation will dictate the choice of application equipment. Information on the equipment selected to apply GLYFOS-SOLUBLE CONCENTRATE HERBICIDE can be found in the APPLICATION EQUIPMENT AND MIXING INSTRUCTIONS section. Use rates can then be selected from the ANNUAL and PERENNIAL WEED CONTROL charts.
GLYFOS-SOLUBLE CONCENTRATE HERBICIDE can be applied prior to planting of all crops for control of emerged weeds listed on the label. Ensure weeds are at the recommended growth stage at the time of application. Apply BEFORE seeding or transplanting crop.
GLYFOS-SOLUBLE CONCENTRATE HERBICIDE may be applied in summer fallow to control weeds listed on the label. Ensure weeds are at the recommended growth stage and actively-growing at the time of application. Reduced control may result if weeds are drought stressed. Repeat treatments may be necessary to control later germinating weeds.
MINIMUM AND ZERO TILLAGE SYSTEMS (ALL FIELD CROPS INCLUDING CEREALS, OILSEEDS, PULSES, FORAGES AND CORN)
GLYFOS-SOLUBLE CONCENTRATE HERBICIDE may be applied before or after seeding but before crop emerges for control of emerged weeds in minimum and zero tillage cropping systems for all field crops. Weeds should be treated at the growth stage according to the ANNUAL and PERENNIAL WEED CONTROL charts.
DO NOT APPLY AFTER CROP EMERGENCE.
Since GLYFOS-SOLUBLE CONCENTRATE HERBICIDE does not provide residual control, application too far in advance of seeding may allow weeds to germinate between application and crop emergence.
PERENNIAL WEED CONTROL
- Allow 7 days or more after application before tillage.
