The 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 area where temperatures are generally below 250C during periods of active growth, 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 BOBCAT SL during periods of intense rainfall or under conditions which will cause drift or movement to non-target areas (ie windspeeds exceeding 30 kph for ground application or 20 kph for aerial application).
On slopes of 20% to 30% apply BOBCAT SL by strip, spot or stem injection application 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, stress level of plants.

BOBCAT® SL Herbicide is a member of the Triazinone group of herbicides.
BOBCAT SL has the inhibitor of photosynthesis at photosystem II mode of action. For weed resistance management BOBCAT SL is a Group C herbicide.
Some naturally-occurring weed biotypes resistant to BOBCAT SL and other Group C herbicides may exist through normal genetic variability in any weed population. The resistant individuals can eventually dominate the weed population if these herbicides are used repeatedly. These resistant weeds will not be controlled by BOBCAT SL or other Group C herbicides.
Since the occurrence of resistant individuals is difficult to detect prior to use, Adama Australia Pty. Ltd. accepts no liability for any losses that may result from the failure of BOBCAT SL to control resistant weeds. Strategies to minimise the risk of herbicide resistance are available. Consult your farm chemical supplier, consultants, local Department of Agriculture of Primary Industries, or Adama representative.

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 dripline 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 (ie. plants more than 1 m apart), treat on an individual stem basis.
ii) When target plant density is 10,000/ha and greater (ie. 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 (ie. plants more than 2 m apart), treat on an individual stem basis.
ii) When target plant density is 2,500/ha and greater (ie. 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 – ie. 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 ensure its proper absorption into the sap stream. Failure to do this may result in unsatisfactory control.

Use sufficient water for thorough uniform coverage.
For best foliar and residual control, apply as a post-emergent spray during the period of active plant growth and when the air temperature are 250C and above. Applications when vegetation is dormant, semidormant, under moisture stress or during the winter months may not be as effective.
In temperate winter rainfall areas where temperatures are generally below 250C 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 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, ie. use one-third the overall rate when treating one-third of the area.

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
BOBCAT SL 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 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 to 400 L/ha with a properly calibrated boom or 2000-4000 L/ha with hand spray equipment.
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 250-500 mL/100 L of spray (for a surfactant containing 100% active constituent) for improved wetting.
a) All Application Methods
See also specific items listed for each use method.
DO NOT apply on or near desirable trees or other plants (except as recommended for crop use), or on areas where their roots may extend, as guidance this is two times their height, or more depending on the species and other conditions.
DO NOT apply in areas where a surface flow of water could wash the chemical into areas where the roots of desirable trees of plants may extend.
DO NOT drain or flush spray equipment, SPOTGUN or Stem Injector near desirable trees or in areas where their roots may extend.
b) Foliar Spray Applications
DO NOT apply under weather conditions, or from spraying equipment, that may cause spray to drift onto nearby susceptible plants/crops, cropping lands or pastues.
DO NOT use on lawns, walkways, driveways or tennis courts.
