IMPORTANT INFORMATION – Read Before Using
- Avoid application of this product in areas where the roots of desirable trees and/or shrubs may extend unless injury or loss can be tolerated. Root zone areas of desirable trees or vegetation are affected by local conditions and can extend well beyond the tree canopy.
- Avoid overspray or drift to important aquatic and wildlife habitats such as lakes, streams and ponds, shelterbelts, wetlands, sloughs, and dry slough borders, woodlots, vegetated ditch banks and other cover on the edge of fields.
- Certain species may, in particular, be sensitive to low levels of Truvist Herbicide including but not limited to, conifers (such as Douglas fir, Norway spruce, ponderosa pine and white pine), deciduous trees (such as aspen, cottonwood, honey locust, magnolia, poplar species, redbud, silver maple, and willow species), and ornamental shrubs (such as arborvitae, burning bush, crape myrtle, forsythia, hydrangea, ice plant, magnolia, purple plum and yew).
- Injury or loss of desirable trees or vegetation may result if Truvist Herbicide is applied on or near desirable trees or vegetation, on areas where their roots extend, or in locations where the treated soil may be washed or moved into contact with their roots. Consider site-specific characteristics and conditions that could contribute to unintended root zone exposure to desirable trees or vegetation. Root zone areas of desirable trees or vegetation are affected by local conditions and can extend beyond the tree canopy. If further information is needed regarding root zone area, consult appropriate provincial extension service, professional consultant or other qualified authority.
- Do not use on lawns or turf.
- If non-crop sites treated with Truvist Herbicide are to be converted to a food, feed, or fiber agricultural crop, or to a horticultural crop, a field bioassay should be completed before planting the desired crop. Refer to FIELD BIOASSAY section of this label
- Avoid application in or on dry or water containing irrigation ditches or canals including their outer banks.
- Treatment of powdery, dry soil and light, sandy soils when there is little likelihood of rainfall soon after treatment may result in off target movement and possible damage to susceptible crops and desirable vegetation when soil particles are moved by wind or water. Injury to crops or desirable vegetation may result if treated soil is washed, blown or moved onto land used to produce crops or land containing desirable vegetation. Do not apply Truvist Herbicide when these conditions are identified and powdery, dry soil or light or sandy soils are known to be prevalent in the area to be treated.
- Injury to or loss of desirable trees or vegetation may result if equipment is drained or flushed on or near these trees or vegetation, or on areas where their roots may extend, or in locations where the chemical may be washed or moved into contact with their roots.
- In non-crop areas adjacent to desirable vegetation, avoid overlapping spray applications and shut off spray equipment while starting, turning, slowing or stopping to avoid injury to desirable vegetation.
- Applications made where runoff water flows onto agricultural land may injure or kill crops, such as but not limited to canola, pulses, peas, sugar beets, potatoes, tomatoes, soybeans, field beans, alfalfa, grapes, and vegetables.
- Caution is advised when using this product in areas where loss of desirable conifer or deciduous trees and/or shrubs as well as other broadleaf plants, including but not limited to, legumes and wild flowers, cannot be tolerated. Without prior experience, it is advisable that small areas containing these plants be tested for tolerance to Truvist Herbicide and its soil residues before any large scale spraying occurs.
- Low rates of Truvist Herbicide can kill or severely injure most crops. Following a Truvist Herbicide application, the use of improperly cleaned spray equipment to apply other pesticides to crops on which Truvist Herbicide is not registered may result in their damage. Refer to SPRAYER CLEANUP section of this label for details. The most effective way to reduce this crop damage potential is to use dedicated mixing and application equipment.
- It is recommended that treated soils remain undisturbed to reduce the potential for Truvist Herbicide movement by soil erosion due to wind or water.
- Caution is advised when using this product on grass that is stressed by drought, water saturated soils, wide fluctuations in day and night temperatures, low fertility, insect damage, or disease as unacceptable grass injury may occur.
Truvis Herbicide should be used only in accordance with recommendations on this label.
Truvist Herbicide is a dispersible granule that is mixed in water and applied as a spray. Truvist Herbicide may be applied by ground equipment for control of broadleaf weeds including many terrestrial and riparian invasive and noxious weeds. Truvist Herbicide is registered for general weed and brush control on private, public and military lands as follows:
uncultivated non-agricultural areas (such as airports, highway, railroad and utility rights-of-way, sewage disposal areas, etc.); uncultivated agricultural areas - non-crop producing (such as farmyards, fuel storage areas, fence rows, non-irrigation ditchbanks, barrier strips, etc.) and industrial sites - outdoor (such as lumberyards, pipeline and tank farms, etc.).
Truvist Herbicide is quickly taken up by the leaves, stems and roots of plants. The effects of Truvist Herbicide may be seen on plants from within a few hours to a few days. The most noticeable symptom is a bending and twisting of stems and leaves. Other advanced symptoms include severe necrosis, stem thickening, growth stunting, leaf crinkling, calloused stems and leaf veins, leaf-cupping, and enlarged roots. Death of treated broadleaf plants may require several more weeks and up to several months for some woody plant species. Degree of control, and duration of effect depend on the rate used, weed sensitivity and weed size, growing conditions at and following treatment, precipitation, soil organic matter and pH.
Rainfall, soil temperature, and soil pH are important factors affecting Truvist Herbicide breakdown in soil. Truvist Herbicide breakdown is more rapid under conditions of low soil pH, high soil temperature, and high soil moisture. The breakdown process is slower under conditions of high soil pH, low soil temperature and low soil moisture.
Truvist Herbicide is rain-fast at 4 hours after application.
Truvist Herbicide controls susceptible annual weeds by both foliar and root uptake. Best control of emerged annual weeds is obtained when weeds are actively growing, typically June-July. Warm, moist growing conditions promote active weed growth and enhance the activity of Truvist Herbicide; weeds stressed by moisture or temperature extremes may be less susceptible and incomplete weed kill may result. Residual control of weeds germinating after spray application is achieved when Truvist Herbicide is carried into the root zone by rainfall. For best results, sufficient rainfall to move Truvist Herbicide 5 to 7 cm deep into the soil is required after application, before weeds develop an established root system and grow beyond the seedling stage.
