GENERAL INFORMATION:
HYVAR X Weed & Brush Killer Wettable Powder is a wettable powder to be mixed in water and applied as a spray on non-cropland areas where bare ground is desired. It is an effective general herbicide for the control of many annual and perennial weeds, and is particularly useful for control of perennial grasses and brush. Effects are slow to appear and may not become apparent until the chemical has been carried into the root zone of the plants by moisture. The degree of control and duration of effect will vary with the amount of chemical applied, soil type, rainfall, and other conditions. HYVAR X Weed & Brush Killer Wettable Powder is non-corrosive to equipment, non-volatile, and nonflammable.

DIRECTIONS FOR USE:
Apply HYVAR X Weed & Brush Killer Wettable Powder just before or during the period of active growth of weeds. Sufficient moisture from rainfall or artificial means is necessary after treatment to carry the chemical into the root zone of the weeds. If dense growth is present, results will be improved if vegetation is removed before treatment. Do not apply when ground is frozen.
Before spraying, calibrate equipment to determine quantity of water necessary to uniformly cover measured area to be treated. Weigh the proper amount of HYVAR X Weed & Brush Killer Wettable Powder and mix into necessary volume of water (minimum of 20 L per kg of HYVAR X Weed & Brush Killer Wettable Powder). Material must be kept in suspension at all times by continuous agitation. Except for small areas, use fixed-boom power sprayers properly calibrated to insure constant rate of application. Openings in screens should be equal to or larger than 50 mesh. Agitate by mechanical or hydraulic means in the spray tank. If by-pass or return line is used, it should terminate at bottom of tank to minimize foaming. Do not use air agitation. For treating small areas, a tanktype hand sprayer or sprinkling-can may be used; shake or stir frequently.
DO NOT apply by air.
Do not treat ditches, wellheads, bridge approaches. Do not treat sites that are adjacent to and surrounding water supply reservoirs, supply streams, lakes and ponds.
DO NOT apply directly to aquatic habitats (such as lakes, rivers, sloughs, ponds, prairie potholes, creeks, marshes, streams, reservoirs and wetlands) and estuarine/marine habitats. Do not contaminate the above aquatic habitats when cleaning and rinsing spray equipment or containers. DO NOT apply during periods of dead calm or when winds are gusty.
Buffer zones: A buffer zone of 65 metres is required between the point of direct application and the closest downwind edge of sensitive aquatic habitats (such as lakes, rivers, sloughs, ponds, prairie potholes, creeks, marshes, streams, reservoirs and wetlands).
When a tank mixture is used, consult the labels of the tank-mix partners and observe the largest (most restrictive) buffer zone of the products involved in the tank mixture.
Apply no more than 16.8 kg of HYVAR X Weed & Brush Killer Wettable Powder per hectare per year. Make no more than two applications per year.
