Some other varieties,

PIGEON PEAS
Weeds: Apple of Peru, Bladder Ketmia, Gooseberry, Noogoora Burr, Cowvine (Peach Vine), Volunteer Cotton, Yellow Vine, False Castor Oil (Thornapples)
State: Qld, NSW, ACT only – except sandy soils
Rate: 470 g/ha
Critical comments: Rain grown and overhead irrigated crops: Apply immediately after or within a day or two after sowing before crops emerge then irrigate. Otherwise rain after spraying before weeds emerge is necessary to get useful weed control. The longer the time interval between spraying and rain or irrigation the less the effectiveness of the herbicide. MENTOR WG can be applied to a band centred on crop rows for in-row weed control. Untreated soil between treated bands thrown onto treated areas during subsequent cultivation will reduce weed control along rows. MENTOR WG can be applied after pre-sowing Trifluralin treatment. Avoid leaving a depression over the row during planting to enhance crop tolerance.
Furrow irrigated crops: Apply after furrowing out and within two weeks before sowing and incorporate with Lillistone cultivators to finely tilled soil free of emerged weeds. Where grass weeds are expected, add Trifluralin at the rate recommended by the manufacturer for the soil type. For post-emergence weed control: Apply when weeds are in the young seedling stage and actively growing, provided crop plants have at least 2-trifoliate leaves. DO NOT spray if rain is likely to fall within several hours. Transitory damage may occur to the pigeon pea crop but yields will not be significantly affected.

POTATOES
(Some varieties such as Atlantic, Harmony, Nadine and Red Skin varieties are especially sensitive to MENTOR WG. Damage may occur even at the lowest label rate. DO NOT use on Bison potatoes.)
Weeds: Controlled: as per Barley (Vic, SA, Tas).
Suppressed: Annual Ryegrass, Dock, Sub Clover, Summer grasses (Digitaria spp.)
State: All States
Rate: 470 g/ha or 700 g/ha
Critical comments: Spray when potatoes are emerging with the largest shoots not more than 10 cm tall. Use higher rate for emerging Summer grasses.
In Summer crops on soils which dry rapidly on the surface, the young actively growing weeds will be killed but residual effect may be reduced. If there is a subsequent germination of weeds apply a second spray at 470 g/ha (except NSW).
DO NOT use MENTOR WG in Western Australia in the Perth metropolitan area; on the south west Winter potato crops; or on Delaware potatoes on light soils.

State: Vic – Bellarine Peninsula only
Rate: 280-370 g/ha (Winter)
Critical comments: Potatoes may be hilled before or after spraying MENTOR WG. If hilled after spraying a good rain or irrigation is desirable between spraying and hilling. No other cultivation should be necessary. Use higher rate for emerging Summer grasses.

State: Qld – Atherton Tableland only
Rate: 470 g/ha for Winter crops 950 g/ha for Summer crops
Critical comments: Hill up the crop soon after planting. Irrigate to allow weed seeds to germinate and potatoes to begin emerging. Apply as an overall spray to a soil moist to the surface, before all the crop has emerged.

SOYBEANS
(in soils of pH 9 or lower (except cv Triton))
Weeds: Apple of Peru, Bladder Ketmia, Cowvine (Peach Vine), Gooseberry, Noogoora Burr, Volunteer Cotton
State: NSW – clay soils in NW only
Qld – clay soils on Darling Downs only
Rate: 470 g/ha
Critical comments: Rain grown and overhead irrigated crops: Apply immediately after or within a day or two after sowing before crops emerge then irrigate. Otherwise rain after spraying before weeds emerge is necessary to get useful weed control. The longer the time interval between spraying and rain or irrigation the less the effectiveness of the herbicide. MENTOR WG can be applied to a band centred on crop rows for in-row weed control. Untreated soil between treated bands thrown onto treated areas during subsequent cultivation will reduce weed control along rows. MENTOR WG can be applied after pre-sowing Trifluralin treatment. Avoid leaving a depression over the row during planting to enhance crop tolerance.
Furrow irrigated crops: Apply after furrowing out and within two weeks before sowing and incorporate with Lillistone cultivators to finely tilled soil free of emerged weeds. Where grass weeds are expected, add Trifluralin at the rate recommended by the manufacturer for the soil type.
DO NOT use on cv Triton as crop damage may occur.

SUGARCANE
(PLANT CANE (up to 3 leaf stage))

Weeds: Black Pigweed, Caltrop, Ipomoea spp. (Bellvine, Convolvulus, Star of Bethlehem), Pigweed
State: Qld, NSW, WA only
Rate: 800 g to 2 kg/ha

Critical comments: MENTOR WG can be used alone or in mixtures with other residual herbicides. Control of difficult species can be improved in tank mixtures. Use the higher rate for extended residual control. DO NOT use MENTOR WG at this stage for plant crops grown on very light sandy soil. For conventional planting, ensure that the drill profile id broadly shaped so that loose soil slippage from the sides will not occur. Spray as a broadcast or band spray, ensuring even coverage of the soil surface. If applied as a band spray, direct the spray band so that it is centred over the row. For banded applications, weeds germinating in the untreated soil away from the band will need to be controlled by cultivation at the later workings.
DO NOT disturb treated soil surface after application.
DO NOT apply in less than 250 L/ha of spray mixture.
If weeds are larger then the 2 leaf stage at application, add a suitable contact herbicide. Refer to the Compatibility section. Soil should be preferable be slightly moist at application. Incorporation by rain or irrigation within 7 days after application is necessary for best results. Use the higher rates in soils with heavy clay or high organic matter.

Weeds: Amaranth, Bluetop, Ipomoea spp. (Bellvine, Convolvulus, Star of Bethlehem)
State: Qld, NSW, WA only
Rate: 640 g to 1 kg/ha
Critical comments: Using appropriate high-clearance or inter-row equipment, apply as directed sprays, using droppers so that the inter-row areas are completely and evenly sprayed. Use the higher rates when weed growth is advanced. Mix with a suitable contact herbicide at an appropriate rate. Refer to the Compatibility section. Spray before climbing broadleaf weeds, such as vines, are taller than the spray nozzle height. Good coverage of growing tips of vine weeds is neccessary for adequate
control. DO NOT apply in less than 250L/ha of spray mixture. Soil should be preferable be slightly moist at application. Incorporation by rain or irrigation within 7 days after application is necessary for best results.

Apply through applicators fitted with flat fan nozzles and operated at pressures not exceeding 200 kPa to avoid misting and spray drift.
DO NOT follow Autumn plantings of tomatoes with cucurbits or capsicums in the same season.

TRANSPLATED TOMATOES
Weeds: Apple of Peru, Potato Weed
State: NSW, ACT only
Rate: 470-770 g/ha
Critical comments: Apply as a directed spray to weeds at the base of tomato plants. Use the lower rate when tomatoes have

GENERAL INSTRUCTIONS
MENTOR® WG is effective against a range of broadleaf weeds and some grasses. MENTOR WG is absorbed by roots, shoots and leaves of weeds. It can therefore be applied before or after weeds emerge depending on the tolerance of the crop being treated. For recently introduced varieties DO NOT use MENTOR WG unless it is ascertained that the variety to be treated shows sufficient tolerance to the treatment under local climatic conditions.

CROP SAFETY
The use of other herbicides and/or crop oils on broadleaf crops treated with MENTOR WG may cause severe damage.
When tank mixing MENTOR WG with Diuron 500 SC or Diuron 900 WG users are advised to read the diuron label in full, particularly when applying over the top of cane up to 3 leaf stage.

RESISTANT WEEDS WARNING
MENTOR WG Herbicide is a member of the triazinone group of herbicides and has the inhibitor of photosynthesis at photosystem II mode of action. For weed resistance management MENTOR WG is a Group C herbicide. Some naturally occurring weed biotypes resistant to MENTOR WG 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 MENTOR WG or other Group C herbicides. Annual ryegrass biotypes
resistant to diclofop-methyl and other ‘grass specific’ herbicides are often also resistant to MENTOR WG. Before using MENTOR WG on a population resistant to ‘grass specific’ herbicides, have a resistance test conducted to ensure that it is still susceptible to MENTOR WG. 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 MENTOR WG to control resistant weeds. Large numbers of healthy surviving weeds can be an indication that resistance is developing. Efforts should be made to prevent seed set of the survivors.
DO NOT make more than one application of a Group C herbicide to a crop in the same season, either pre-sowing incorporated by sowing or post-crop and weed emergence.
If the user suspects that a Group C resistant weed is present, MENTOR WG or other Group C herbicides should not be used.
Strategies to minimise the risk of herbicide resistant are available. Consult your farm chemical supplier, consultant, local Department of Agriculture or Primary Industries, or Adama representative.

EXPORT OF TREATED PRODUCE
Growers should note that MRLs or import tolerances do not exist in all markets for edible produce treated with MENTOR WG. If you are growing edible product for export, please check with Adama Australia Pty. Ltd. for the latest information on MRLs and import tolerances before using MENTOR WG.

COMPATIBILITY
MENTOR WG is compatible with 2, 4-D Amine 625, Actril* OS, Ametrex 800 WG, Brodal* Options, Enforcer 75-D, Adama Diuron 500 SC, Adama Diuron 900 WDG, isoxaflutole, Lynx, Spraytop, Trilogy, Le-Mat*, Pendimethex, Tackle and Wetspray 600.
MENTOR WG is compatible with Nitifol* on potatoes.
DO NOT mix concentrates together but add each to the spray tank separately. As formulations of other manufacturers’ products are beyond the control of Adama Australia Pty. Ltd. all mixtures should be tested prior to mixing commercial quantities. As changes in climatic conditions can alter the sensitivity of plants to mixtures of sprays, Adama Australia Pty. Ltd. cannot be responsible for the behaviour of such mixtures.

MIXING
MENTOR WG is a water dispersible granule formulation to be mixed with water and applied as a spray. Before spraying calibrate equipment to determine the quantity of water necessary to uniformly cover the measured area to be treated. Carefully weigh the amount of MENTOR WG required and add to partially filled spray tank with agitation operating. Top up to the correct volume with water. THE MATERIAL MUST BE KEPT IN SUSPENSION AT ALL TIMES BY CONTINUOUS AGITATION. In tank mixes MENTOR WG must be in suspension before adding the companion herbicide or liquid fertiliser.

APPLICATION
General
Best results are obtained if treatment is made to moist soil and moisture is supplied by rainfall or sprinkler irrigation (6-12 mm) within 2 weeks after application. If heavy rains occur soon after application, injury to the crop may result.
Pre-emergence
Soil should preferably be moist to the surface and must not be cloddy or have residues of a previous crop on the surface. It is better to delay pre-emergence spraying of loose or fluffy soils until there is a good soil settling rain. Rain or irrigation soon after spraying is required to activate MENTOR WG.
Post-emergence
Post-emergence spraying will control young actively growing emerged weeds through leaf uptake. Subsequent pre-emergence control of later germinating weeds requires rain or irrigation after spraying. Crops may show slight chlorosis or necrosis after spraying. Two sunny days before spraying enhances crop tolerance. Heavy rain (80-100 mm) after spraying on deep sandy or friable well structured soils may leach MENTOR WG beyond the root zone thus reducing residual effect.
Ground Spraying
Apply MENTOR WG through a carefully calibrated boom spray set at 200 to 300 kPa pressure (except for tomatoes in Qld only) fitted with fan nozzles. Use a convenient quantity of water (50-100 L/ha). Cone nozzles and other means of application are not satisfactory and should not be used. When spraying avoid over-lapping and shut off spray booms while starting, turning slowly and when stopped. Neglect of these procedures will cause higher rates of application resulting in crop damage. Delay post-emergence spraying if rain is expected within a few hours.
Sugarcane
DO NOT apply in less than 250 L/ha of spray mixture. Soil should preferably be slightly moist at application. Incorporation by rain or irrigation from 2 to 7 days after application is best for optimum results in sugarcane in hot and high UV radiation environments. Soil must not be cloddy or have excessive crop residue from a preceeding crop. Trash blankets must be thoroughly compacted and broken down for any pre-emergence efficacy. DO NOT apply by aircraft.
Aerial Spraying
Wind: Spray only in crosswinds, otherwise uneven coverage may result. DO NOT spray onto inversions or in dead calm conditions. DO NOT spray when winds are light and variable in direction unless smoke indicators or the spray cloud show that the spray is going down into the crop. Spray drift may damage adjoining crops. Make sure that the wind is blowing away from crops for which MENTOR WG is not recommended.
Flying: Fly with the wheels 2 to 3 metres above the crop as “wheels on crop” spraying causes uneven distribution. Track spacing must be uniform and suited to the type of aircraft and crosswind speed.
Droplet size: For grasses and vertical weeds, use fine droplets. For horizontal weeds and drift limitation, use droplets over 200 microns and increase volume.
Water volume: Use 20 to 30 L water/ha.
Pre-plant Incorporated Treatment

MENTOR WG + Trifluralin: Add MENTOR WG to water in spray tank with agitator running as above. Maintain agitation then add Trifluralin at the recommended rates (refer to Trifluralin label).
