CONIFER RELEASE (DIRECTED SPRAY) - GROUND AND AERIAL

General Information

GENERAL PRODUCT AND APPLICATION INFORMATION

FORZA SILVICULTURAL HERBICIDE is a non-selective, non-residual herbicide containing 360 g/L glyphosate (acid equivalent) as isopropylamine salt, formulated as a water soluble liquid. This product controls or suppresses listed undesirable vegetation species, at the appropriate rates, in conifer and deciduous release programs, as well as other forestry sites. The product is absorbed through the foliage and translocates throughout the plant down to the root system. Visible symptoms, such as gradual wilting and yellowing, are usually obvious within 2 to 4 days of application to annual weeds, but may not be apparent for 7 to 14 days on perennial weeds and woody brush. Refer to Section 11 of the label for a list of the undesirable vegetation that is controlled by this product.

Avoid contact with foliage, green stems or fruit of non-target crops, since damage to these crops may result. Apply as directed.

FORZA SILVICULTURAL 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 label instructions.

FORZA SILVICULTURAL HERBICIDE may be applied utilizing air, ground boom or boomless, wiper or injection application equipment for the control of vegetation in conifer release, site preparation, and rights of way management. For deciduous release, forest roadside vegetation management and forest tree planting nurseries apply FORZA SILVICULTURAL HERBICIDE utilizing ground spray, wiper or injection application equipment.

Application should be made when vegetation has emerged to the stages described for control of such vegetation to provide adequate leaf surface to receive the spray. Unemerged plants arising from underground rhizomes or rootstocks of perennials will not be affected by the spray and will continue to grow.

Extremely cool or cloudy weather at treatment time may slow down activity of this product and delay visual effects or control. Visible effects are a gradual wilting and yellowing of the plant, which advance to complete browning of above ground growth and deterioration of underground plant parts.

Best control of most perennial herbaceous vegetation is obtained when treatment is made at late growth stages approaching maturity. Do not apply in autumn after leaf drop has started. Always use the higher rate of this product per hectare within the recommended range on hard to control species or when vegetation growth is heavy or dense.

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.

Do not treat weeds and herbaceous species 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. FORZA SILVICULTURAL HERBICIDE does not provide residual weed control. For best results spray coverage should be uniform and complete. Do not spray weed foliage to the point of runoff.

MIXING and APPLICATION INSTRUCTIONS

MIXING

For ground, aerial or industrial type sprayers, fill the spray tank with one half the required amount of water. Add the proper amount of FORZA SILVICULTURAL HERBICIDE (see Section 9.2 or 13) and mix well before adding the remaining portion of water. Placing the filling hose below the surface of the liquid solution will prevent any excessive foaming. Remove the hose from the tank immediately after filling to avoid back siphoning into water source (a one-way valve should be installed to prevent back siphoning). Use of mechanical agitators may cause excessive foaming. By-pass lines should terminate at the bottom of the tank.

9.2 APPLICATION

Apply spray solutions in properly-maintained and calibrated equipment capable of delivering desired volumes. Use flat fan nozzles in boom sprayers.

General: To control or suppress most herbaceous weeds, woody brush and trees, apply 3 to 6 litres of this product per hectare using aerial, ground boom, boomless, mist blower equipment, or apply as a 1 to 2% solution using hand-held high volume equipment.

Site preparation: For control of perennial herbaceous weeds in site preparation applications using aerial, ground boom or boomless, or mist blower equipment, apply 7 to 12 litres of this product per hectare as directed in the recommended volume of clean water to the foliage or actively-growing vegetation.

Note: For specific rates for wick or wiper applicators, see Section 12.5 of the label. To control perennial weeds, and woody brush and trees as listed, apply FORZA SILVICULTURAL HERBICIDE in 20 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 FORZA SILVICULTURAL HERBICIDE in 20 L to 100 L of water per hectare as a broadcast spray. Use no more than 275 kPa pressure.

AERIAL EQUIPMENT

Use the recommended rates of this herbicide in 20 to 100 L of water per hectare. As density of vegetation increases, spray volume should be increased within the recommended range to ensure complete coverage. Coarse sprays are less likely to drift, therefore do not use nozzles or nozzle configurations that dispense spray as fine spray droplets. Do not angle nozzles forward into the airstream and do not increase spray volume by increasing nozzle pressure. Ensure uniform application--To avoid streaked, uneven or overlapped application, use appropriate marking devices, or equivalent electronic positioning systems (GPS).

Thoroughly wash aircraft, especially landing gear, after each day of spraying to remove residues of this product accumulated during spraying or from spills.

PROLONGED EXPOSURE OF THIS PRODUCT TO UNCOATED STEEL SURFACES MAY RESULT IN CORROSION AND POSSIBLE FAILURE OF THE PART. LANDING GEAR IS MOST SUSCEPTIBLE. The maintenance of an organic coating (paint) which meets aerospace specification MIL-C-38412 may prevent corrosion.

BOOM EQUIPMENT

FOR CONTROL OF HERBACEOUS WEEDS AND WOODY BRUSH AND TREES LISTED IN SECTION 11 ON THE LABEL USING CONVENTIONAL BOOM EQUIPMENT -- Apply this product in 100 to 300 L of clean water per hectare as a broadcast spray using no more pressure than 275 kPa.

BOOMLESS EQUIPMENT

FOR CONTROL OF HERBACEOUS WEEDS, WOODY BRUSH AND TREES LISTED IN SECTION 11 ON THE LABEL USING BOOMLESS EQUIPMENT SUCH AS CLUSTER NOZZLES -- Apply this product in 100-350 L of clean water per hectare as a broadcast spray using no more pressure than 275 kPa.

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. Avoid spraying desirable plants. Mixing: Mix the proper amount of FORZA SILVICULTURAL HERBICIDE with water in a large container. Fill the sprayer with the mixed solution. Unless otherwise stated, make a 1% solution in water (1 L of FORZA SILVICULTURAL HERBICIDE in 100 L of water). A 2% solution (2 L in 100 L of water) should be used on harder to control perennials.

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.

WIPER, WICK AND ROLLER EQUIPMENT

These applicators apply FORZA SILVICULTURAL HERBICIDE solution directly onto the weeds by contacting the weed with an absorbent material containing the herbicide solution. The weeds must be above any desired vegetation to prevent contact with the desired vegetation.

Mixing: Mix the proper amount of FORZA SILVICULTURAL HERBICIDE with water in a large container. Use this mixed solution in the wiper, wick or roller equipment.

MIST BLOWER EQUIPMENT

FOR CONTROL OF HERBACEOUS WEEDS, WOODY BRUSH AND TREES LISTED IN SECTION 11 ON THE LABEL--Use the recommended rate of this product in at least 200 L of water per hectare.

Limitations, Restrictions, and Exceptions

DIRECTED SPRAY APPLICATIONS

Conifer Release

Use this product to control herbaceous and woody species as listed in Section 11 of the label. Apply when the undesirable species are actively-growing and the foliage is full and well developed. This product does not provide pre-emergent weed control. Repeat treatments may be necessary to control weeds that generate from underground parts or seed. Undesirable deciduous species may be treated when they already have autumn colour, provided there has been no major leaf fall.

For perennial broadleaf species, apply when most weeds have reached early head or early bud stage of growth. For annual and perennial grasses, apply when most weeds are 20 cm in height (3-4 leaf stage of growth). Direct spray so that the foliage of undesired vegetation is thoroughly wetted. Do not spray foliage to the point of run-off. Applying the product to conifers during their period of active growth (before lignification) may cause tree injury. Under such conditions, take the necessary precautions to ensure that spray, mist or spray drift does not come into contact with the foliage or green bark of conifers being cultivated.

FORZA SILVICULTURAL HERBICIDE may be applied on sites regenerated by the following species (partial list): spruce (Picea spp.), pine (Pinus spp.), hemlock (Tsuga spp.), Douglas fir (Pseudotsuga spp.). No time interval is required between tree planting and application of the product. For specific rates, application instructions, and vegetation controlled see Sections 9 and 11 of the product label. Do not allow spray to come in contact with foliage, green stems or fruit of non-target crops, since they may be killed or severely damaged.
