GENERAL INSTRUCTIONS
RESISTANT WEEDS WARNING
MATRIX® 500 Herbicide is a member of the Benzofuran group of herbicides. MATRIX 500 is a herbicide with inhibitors of fat synthesis (not AACase inhibitors) mode of action. For weed resistance management MATRIX 500 is a Group J herbicide.
Some naturally-occurring weed biotypes resistant to MATRIX 500, and other Group J 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 MATRIX 500 or other Group J herbicides.
Since the occurrence of resistant weeds is difficult to detect prior to use, Adama Australia Pty. Ltd. accepts no liability for any losses that may result from the failure of MATRIX 500 to control resistant weeds.

GENERAL
The product is a pre- and post-emergence herbicide for control of certain broad-leaved weeds and grasses. For post-emergence applications, weeds should be at the seedling to 4 leaf stage. Prior to sowing any follow-up crops other than beet or ryegrass, those areas previously treated should be thoroughly tilled (including ploughing).
1. BEET CROPS: Slight foliage distortion to beet may occur following treatment. These effects are short-lived and do not affect crop yield. Pre-emergence treatment with this product may be followed by post-emergence application of Betanal* or a mixture of both.
2. USE OF MATRIX 500 IN MIXTURE WITH Betanal ON BEET CROPS: Before using this mixture carefully read the Betanal label; note warning about use in temperatures above 30°C. For best results the interval between treatment and subsequent rainfall or irrigation should be at least six (6) hours. In Tasmania, this treatment should follow the use of a pre-emergence herbicide. This mixture is recommended to provide a wider spectrum of post-emergence weed control and longer residual activity than Betanal used alone. Weeds controlled include additional weeds listed on the Betanal label.
3. RYEGRASS: This product will reduce clover stands by 40-60%. For best control of barley grass, apply to closely grazed pasture (3-5 cm high). Raw organic matter can reduce efficacy and retreatment may be necessary. Remove organic litter and harrow large dung pats before application. In areas of dense Barley Grass, drill or oversow with ryegrass as soon as possible after treatment.
4. TURF: This selective herbicide should be applied before, or early after germination or emergence of Winter Grass (Poa annua) when it occurs in fine turf situations. It is selective in Ryegrass, Fescues, Kentucky Bluegrass, Queensland Blue Couch, Kikuyu, Bent grasses (including Brown Top Bent) and Couch, when applied as directed. Applications are made at monthly intervals for 3-4 months to control winter grass gradually, while allowing the desirable turf grasses to take over without unsightly bare patches of dead Winter Grass. Oversowing and reseeding should NOT take place within one month of spraying.

MIXING
MATRIX 500 is a suspension concentrate which mixes easily with water. Prior to pouring, gently invert or roll container to ensure all active constituent is in suspension. Part-fill the spray tank with clean water. Add the correct amount of MATRIX 500 and top up with water to the required level. Thorough agitation of the mixture is necessary before spraying. Mix only enough chemical for immediate use. When using a mixture of MATRIX 500 and Betanal, half-fill spray vat with water then stir or agitate while adding the required quantities. Top up with water and stir again. Use as soon as possible after mixing.
Do NOT add other herbicides or surfactants unless specifically recommended.

APPLICATION
Boom Spray: Apply in a suitable volume of water to give good even coverage. When used pre-emergence, apply to moist soil surface. Ensure that the nozzles are set at the correct height to give even coverage ie. 50-60 cm above the pasture or crop. Use a nozzle and pressure combination to give a fine spray (200-300 kPa). Make sure nozzle tips are clean, undamaged and all the correct type and size. Impact nozzles or broadcast nozzle clusters should NOT be used.
Do NOT use filter gauzes finer than 0.3 mm. After use, wash all equipment thoroughly with water containing liquid detergent. Spray out completely, then rinse twice with clean water. To allow air access, remove nozzles and open spray tank lid.
