Critical comments: CROP STAGE
Cereals
Up to 750 mL (3 leaf to fully tillered stage - Z13 to 30).
Over 750 mL (5 leaf to fully tillered stage - Z15 to 30).
Optimum results are achieved when sprayed at 3-5 leaf crop stage (generally 4-8 weeks post sowing).
WA only: DO NOT apply to Barley or Kulin Wheat before the 5 leaf stage (Z15).
Warning: LEGACY MA may cause transient crop yellowing of cereals. Some varieties of oats have not been tested. (Refer to “Crop Tolerance” section of General Instructions).
Clover
Application is recommended prior to the eighth trifoliate leaf stage, however, applications prior to the third leaf stage may result in crop damage especially under stressed conditions and in sandy soils. DO NOT apply to Annual Medics or lucerne.
Warning: LEGACY MA may cause transient crop yellowing of clover, and may affect growth and seed set of some varieties of clover. (Refer to “Crop Tolerance” section of General Instructions).
WEED STAGE
Apply when weeds are actively growing. In most situations the rate specified for each weed size will give satisfactory control. Under certain conditions such as:
- high crop and weed density
- late season germinations
- abnormal weed growth (including early flowering), higher rates of product (up to the maximum rate of application specified for that weed) may be required.
LEGACY MA will not effectively control:
- regrowth of suppressed weeds;
- transplanted weeds;
- regrowth from rhizomes or roots;
- weeds growing under stress from previous herbicide applications.
GRAZING
Efficacy on larger weeds will be improved by grazing with normal levels of stock after the 7 day withholding period. Refer to ‘Protection of Livestock’ for grazing precautions.
APPLICATION
Activity of this product will be reduced if weeds are stressed. Optimum results will be obtained if good soil moisture exists at and after application. Where crop or weed density is high, water volume should be increased.
WILD RADISH
LEGACY MA will provide residual control of Wild Radish for up to 4 weeks after application. Effective residual activity of this product may be reduced where:
- rates lower than 1.0 L/ha are used;
- dry conditions prevail;
- poor coverage of the soil surface is achieved;
- crop is planted in non-wetting sand;
- soils contain a high content of organic matter.
Optimum results will be obtained if good soil moisture exists at and after application.

GENERAL INSTRUCTIONS
RESISTANT WEEDS WARNING
LEGACY® MA Herbicide is a member of the phenoxy and nicotinanilide groups of herbicides and acts by inhibiting carotenoid biosynthesis at the phytoene desaturase step (PDS inhibitors) and disrupting plant cell growth. For weed resistance management LEGACY MA is both a Group F and a Group I herbicide. Some naturally occurring weed biotypes resistant to LEGACY MA and other Group F and I 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 LEGACY MA or other Group F or Group I 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 LEGACY MA to control resistant weeds.

TOLERANCE
Some pre-emergence herbicides, such as atrazine, can cause stress to certain crops resulting in an increase in crop damage when using this product. Subterranean clover is particularly sensitive.

CEREALS
After application some transient crop yellowing may occur. This usually appears as yellow or white banding on leaves. Provided the crop is not under stress from pre-emergent herbicide, root disease, insect damage, frost, dry or excessively moist conditions, the development of the crop and subsequent growth will be unaffected.

WARNING (Oats)
The tolerance of oat varieties Esk and Nile (the two main varieties grown in Tasmania) to LEGACY MA has not been tested. Test a small area of crop before using LEGACY MA over large areas. Consult your local Adama representative for advice on specific varieties.

PASTURE
The tolerance of clover varieties to LEGACY MA can vary with rate of application, soil type, crop health, stage of growth and degree of moisture and temperature stress.

WARNING
LEGACY MA may result in transient crop yellowing and suppression of growth with a resultant initial reduction in dry matter, particularly at rates in excess of 500 mL/ha and in areas of double spray. For this reason we recommend application prior to the 8 trifoliate leaf stage.
However, at the lower rates (500 mL/ha and less) and under normal growing conditions, subsequent growth and seed yield should not be affected. Under normal growing conditions, the following varieties have shown acceptable levels of foliage tolerance to LEGACY MA applied at 500 mL/ha:
ArrowLeaf: Zulu
Balansa: Paradana
Berseem: Sacromonte
Persian: Kyambro, Lupers, Maral
White: Haifa
Subterranean Clover: Daliak, Dalkeith, Denmark, Esperance, Geraldton, Goulburn, Karridale, Larissa, Leura, Mt.Barker, Nungarin, Rosedale, Seaton Park, Trikkala and Woogenellup.
The effects of LEGACY MA on clover seed yield have been tested on the following varieties. Under normal growing conditions they show acceptable levels of tolerance to LEGACY MA applied at 500 mL/ha:
Subterranean Clover: Esperance, Goulburn, Larissa, Seaton Park and Trikkala.

WARNING
Rose and Strawberry clover have shown increased sensitivity to LEGACY MA. LEGACY MA may affect the seed yield of Subterranean Clover variety Woogenellup. Some pasture grasses, including Phalaris and Cocksfoot, may show some initial reduction in vegetative growth after application of LEGACY MA. Care should be exercised if sensitive clover varieties or grasses are included in the pasture sward.
Varieties not listed should be tested before using LEGACY MA over large areas. Consult your local Adama representative for advice on specific varieties.

SUBSEQUENT CROPS
To reduce effect on subsequent susceptible crops (e.g. canola), ensure thorough cultivation of soil prior to the sowing of these crops.

MIXING
To ensure even mixing, half fill the spray tank with clean water and add the required amount of product. Agitate thoroughly then add the remainder of the water. Agitate again before spraying commences.
Reseal part-used product container immediately after use. Spray mixtures containing LEGACY MA should not be left to stand overnight. Prolonged periods of exposure to cold temperatures could result in settling out of the product in the mixture.

WARNING
The rubber components present in some spraying units may be affected by exposure to the solvents in LEGACY MA and some other agricultural products. To reduce this risk it is recommended that the spray unit be thoroughly washed with a boom cleaner and fresh water after use. Contact the spray unit manufacturer to determine the suitability of the rubber components for use with agricultural products.

APPLICATION
Boom Sprayer: A minimum of 50 L of water per hectare should be used, however, for optimum results water rates of 70-100 L/ha are recommended. Increase the water volume if weed infestation is heavy or crop cover is dense. Complete coverage of weeds is essential.
Aircraft (NSW, Vic, SA only): Apply in a minimum of 30 L water per hectare. Effective weed control will only be achieved where good coverage of leaf surface is achieved.

When mixing with other herbicides, crop yellowing may be enhanced. When mixing with Rhino, Wildcat or Puma Progress some reduction in the efficacy and speed of action of these products may occur. If the crop is stressed, the application of the herbicide tank-mixtures may cause yield reduction. When mixing with Cadence a temporary wilting may be evident in some crops after application. Growers should seek advice before spraying recently released cereal varieties.
Use the recommended rates for both herbicides in the tank-mixture as well as the surfactant recommendation of the grass herbicide. If another herbicide is applied as a tank mix, observe the plantback restrictions on that label.
DO NOT add surfactant when mixing LEGACY MA and Lynx.
Simazine: Refer to the simazine label for correct application rates, especially with regard to soil types. This product may be mixed in the spray tank with one of the following insecticides according to the directions for use on this product: Hallmark* 50EC, Alpha-Scud Elite, Karate*, Ballistic Elite and Venom.

WARNING
DO NOT use crop oils with LEGACY MA or LEGACY MA tank mixtures with other products in cereals. As formulations of other manufacturer’s products are beyond the control of Adama, all mixtures should be tested prior to mixing commercial quantities.
