GENERAL INSTRUCTIONS This product is both foliar and root absorbed and will give residual soil activity. For best foliar and residual control, apply during periods of active plant growth. Application when vegetation is dormant, semi-dormant, under moisture stress, or during winter months may not be as effective. In temperate winter rainfall areas where temperatures are generally below 25°C during periods of active growth, the overall effect may be slower to appear. For best control of perennials, apply during the months of spring in these areas. In WA and SA, apply only during April-August when adequate rainfall is expected. Sufficient moisture is required after treatment to promote root absorption by the weed species. DO NOT apply Conquest HEXATRON 250 Herbicide during periods of intense rainfall or under conditions that will cause drift of movement to non-target areas (i.e., wind speeds exceeding 30kph for ground application or 20kph for aerial application). On slopes of 20% to 30%, apply Conquest HEXATRON 250 Herbicide by strip, spot, or stem injection applications only. ON slopes greater than 30%, apply by spot or stem injection application only. The L/ha rates in the DIRECTIONS FOR USE Tables refer to SPRAYED hectare. Visible symptoms and degree of effectiveness will vary with temperature, soil types, rainfall, soil moisture, and stress level of plants.

SPOTGUN APPLICATIONS a) To the Soil For trees greater than 5 m tall, consider the stem injection technique as it requires less product. For best results on sucker regrowth use the rate recommended for the tallest bushes (trees) listed in the Directions for Use tables, as suckers grow from the roots of previous trees with large food reserves. Use the spear attachment for the SPOTGUN when treating brush or timber on sloping ground. Apply on the uphill side of the slope to a depth of 2 to 3 cm. Avoid application onto ash in recently burnt areas as this may reduce the treatment’s effectiveness. The product can be applied through the SPOTGUN at any time of the year; but results may be slow to appear if application is made to dry soil. For optimum results, the following conditions are required:- a) Moist soil at application, or sufficient rainfall after treatment to promote root absorption by the target bush or trees. b) Active plant growth. Either the on-surface nozzle or spear attachment of the SPOTGUN may be used. When using the on-surface nozzle apply the product onto bare soil. In areas where there is pasture growth or leaf litter covering the soil surface, best results are obtained using the SPOTGUN with its spear attachment. Use the spear attachment for the SPOTGUN when treating brush or timber on sloping ground. Apply on the uphill side of the slope to a depth of 2 to 3 cm. Small patches of pasture with its roots extending under the applied spot will also be controlled. Pasture will re-establish itself in affected areas, normally within 12 to 24 months of application. Individual Brush/Tree All spots to be placed between the base and the drip line unless otherwise specified. Where only two spots are applied per plant, place spots on either side of the plant. Where applicable, apply multiple spots each evenly spaced around the plant. Grid Pattern Application Unless otherwise indicated; Bushes/trees up to 1 m tall. i) when the target plant density is less than 10,000/ha (i.e., Plants more than 1 m apart), treat on an individual stem basis. ii) when the target plant density is 10,000/ha and greater (i.e., Plants 1 m or less apart), treat using the 1 x 1 m grid pattern technique. Bushes (trees) 1 to 7 m tall or suckers. i) when target plant density is less than 2,500/ha (i.e., plants more than 2 m apart), treat on an individual stem basis. ii) when target plant density is 2,500/ha and greater (i.e., plants 2 m or less apart), treat using the 2 x 2 m grid pattern technique. b) Stem Injection Application For multi-stemmed trees, treat each stem as an individual tree. Bushes (trees) up to 5 m tall. 1 cut/bush (tree) at waist height. Trees 5 to 18 m tall. 30 cm centre to centre cut spacing around the circumference at waist height. The Stem Injection technique requires less product than SPOTGUN applications to the soil for Eucalypts greater than 5 m tall. The product can be stem injected at any time of the year, but for best results treatment should be at a time of good sap flow. Avoid periods of drought stress. It is recommended that the injection cuts be made at a comfortable height – i.e., waist height. Use a narrow-bladed axe (5 to 7 cm wide blade) to make the cuts. A suitable Tree injector should be used to place the product into the cut. It is important that the axe cuts be made to the correct depth – this is down into the sap stream. Ensure the cuts are deep enough to properly penetrate the bark – the thickness of the bark varies from one species to another. Ensure that the product is injected into the cut within 5 seconds of the cut being made. This ensures its proper absorption into the sap stream. Failure to do this may result in unsatisfactory control.

FOLIAR SPRAY APPLICATIONS Use sufficient water for thorough uniform coverage. For best foliar and residual control, apply as a postemergent spray during the period of active plant growth and when the air temperature is 25°C and above. Applications when vegetation is dormant, semi-dormant, under moisture stress, or during the winter months may not be as effective. In temperate winter rainfall areas where temperatures are generally below 25°C during the period of active plant growth, the foliar effect may be slow to appear. In these areas herbicide activity is more dependent on root absorption. For residual control, sufficient rainfall is required after treatment to promote root absorption by the weeds. Results obtained may vary with the amount of chemical applied, rainfall, air temperature, soil type, and other conditions. All use rates of the product are expressed as overall rates. For band treatment use proportionately less, i.e., use one-third the overall rate when treating one-third of the area.

EQUIPMENT AND APPLICATION a) SPOTGUN and Stem Injection i) Applications to the soil – the product is to be applied using a SPOTGUN. ii) Stem Injection – the product is to be applied using a suitable tree injector. b) Foliar Spray Applications Conquest HEXATRON 250 Herbicide is a water miscible liquid formulation. The product is mixed with water and applied at recommended rates with ground equipment. Partially fill the spray tank with water and add the correct amount of the product for the area to be sprayed with the agitation system engaged. Top up to the correct volume with water, and for best results keep the spray solution agitated whilst spraying. To prevent nozzle blockage, strainer and nozzle screens should be 50 mesh or coarser. Ground Application: Apply in 100-400L per sprayed hectare with a properly calibrated boom or 2000-4000L per sprayed hectare with hand spray equipment.

USE OF SURFACTANTS/WETTING AGENTS Use a surfactant/wetting agent for foliar spray applications only, by ground equipment. A non-ionic surfactant/wetting agent may be added at the rate of 250-500mL/100L or spray (for a surfactant containing 100% active constituent) for improved wetting.
