GROUP H I HERBICIDE

For the post-emergent control of certain broadleaf weeds in wheat, barley, oats, cereal rye and triticale as specified in the DIRECTIONS FOR USE table

GENERAL INSTRUCTIONS
Precept is a selective phenoxy (Group I) and pyrazole (which inhibits 4-HPPD – Group H) herbicide. It is predominantly a foliar herbicide with limited activity via the soil. Precept will not reliably control weeds that emerge after spraying. Results are best under good growing conditions and application to weeds or crop under stress should be avoided. Precept will substantially reduce the growth of many weeds rather than give complete plant kill.
Refer to the Critical Comments in the Directions for Use table above and further information in the following General Instructions, which includes;

6. Crop rotation recommendations
It is important that all parts of the General Instructions are read in conjunction with the Directions for Use table.

1. Adjuvant/Crop Oil/Surfactant/Wetting agent
Spray grade liquid ammonium sulfate or a recommended crop oil must be used in conjunction with Precept or Precept tank mixtures with other products in cereals. Recommended adjuvants include spray grade liquid ammonium sulphate at 500 grams active ingredient/ha or the crop oil Hasten® (0.5 to 1% v/v), Supercharge® at 0.75% v/v or Uptake® at 0.5% v/v. The use of Hasten at 0.5% v/v may reduce speed of control compared to Hasten at 1% v/v. Consult Bayer CropScience Pty. Ltd. for information on other adjuvants.
DO NOT use non-ionic surfactants, e.g. BS 1000 unless tankmixing with Hussar® OD or Wildcat® 110. For mixtures with compatible products refer to the table Adjuvant Recommendation with Compatible Products in the Compatibility section (section 4) below.

2. Application
Ensure that complete and even spray coverage of all weeds is achieved.
Please refer also to the SPRAY DRIFT RESTRAINTS and MANDATORY NO-SPRAY ZONES within the DIRECTIONS FOR USE section of this label.

a) Mixing
Half fill the spray tank with water, then with agitators in motion, add any compatible granular products if required, then add the correct amount of Precept Selective Herbicide directly into the spray tank. Add other relevant compatible herbicides, then adjuvant or crop oil as recommended. Complete filling the tank with agitators in motion. Agitation must continue before and during spraying.

b) Spraying Equipment
Ground Sprayers – Standard boom sprayers only are recommended and must be fitted with by-pass or mechanical agitation. It is recommended that 50 to 100 L water/ha is applied. However in the case of advanced weeds (greater than 4 leaf at application), heavy weed density (causing shading of weeds) or heavy crop canopy (causing shading of weeds), it is recommended that a spray volume in the range 70 – 150 L water/ha is used as adequate coverage is critical to ensure control.
The use of a nozzle that will deliver a MEDIUM spray quality as defined by ASABE S572 Standard or BCPC Guideline is recommended.
Aerial application – Apply in a minimum of 30 L water per hectare.
Effective weed control will only be achieved where good coverage of each weed leaf surface is achieved, on actively growing weeds. Weed size needs to be considered in conjunction with weed density. If an aerial application of Precept is to be considered then treat target weeds at the earliest possible growth stage.
The rate of Precept should be increased (up to a maximum of 2.0 L/ha) to improve reliability when applying with aircraft. Use a recommended spray oil as the adjuvant rather than ammonium sulphate when applying by aircraft.
DO NOT spray too high above the ground.
Misters – DO NOT apply Precept through a mister.

c) Sprayer Clean Up
The sprayer must be thoroughly cleaned before being used again to spray crops other than winter cereals.
Warning: The rubber components present in some spraying units have shown they may be affected by exposure to undiluted Precept. To reduce the risk of the rubber components of the spraying unit being adversely affected by exposure to the product, it is recommended that the spray unit be thoroughly cleaned after each use.
Cleaning procedure: Ensure that the following operation is carried out in an area that is clear of waterways, desirable vegetation and tree roots, and preferably in an area where drainings can be contained.
Fill the boom tank with water, rinse and repeat this procedure (i.e. fill and rinse the tank twice) then remove and clean all filters (inline and nozzle) separately. A boom cleaner should be used in this process to provide an effective cleaning technique for Precept. This should be done immediately after spraying is finished to prevent dried residues adhering to the tank/lines/filters.
When a tank mixture of Precept with a compatible product has been used, more rigorous cleaning of the sprayer may be required than when using Precept alone. Refer to the compatible product label for appropriate instructions in this event.

3. Other Factors Influencing Weed Control
a) Application time of day
Optimum performance of Precept occurs when it is applied in warmer temperatures with good light intensity. To maximise efficacy apply Precept during the day, at least 1 hour before sunset, particularly if followed by low overnight temperatures.

b) Effect of climate
Activity of Precept Selective Herbicide will be reduced if weeds are stressed. Optimum results will be obtained if good temperature, good light intensity and good soil moisture exists at application.
Rainfast period
DO NOT use if rainfall or irrigation is to occur within 2 hours of application.
Temperature
DO NOT apply to frost affected weeds or if frosts are imminent.
The use of Precept Selective Herbicide at 2 L/ha may provide better control of weeds during frosty periods.

c) Weed coverage
Reduced control will occur where target weeds overlap each other, non target weeds overlap the target weed, ground or standing stubble impedes excellent coverage or crop impedes excellent coverage of all target weeds. Increasing the Precept rate up to 2 L/ha will improve control in most situations.
Because weed overlap may cause shading of weeds lower in the plant canopy or other factors may impede excellent herbicide leaf contact, a follow up application of a suitable herbicide may be required to control plants remaining after an application of Precept.

d) Weed density
For reliable control good contact must be made with each plant. High weed density may cause shading of plants lower in the weed canopy. In dense weed or crop stands a follow up application of a suitable herbicide may be required to control remaining plants.
DO NOT use the minimum specified rate where excellent coverage of each weed through the canopy is not possible. For dense weed populations, increasing the rate to 2 L/ha will improve control in most situations. Because high weed density may cause shading of weeds lower in the plant canopy a follow up application of a suitable herbicide may be required to control plants remaining after an application of Precept.
Where crop or weed density is high, water volume should be increased as recommended in the Application section (section 2) above.

e) 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 or weed density
*later germinations
*abnormal weed growth including early flowering
- higher rates of Precept Selective Herbicide up to 2 L/ha may be required.
Precept Selective Herbicide may not effectively control:
* regrowth of suppressed weeds;
* transplanted weeds;
* weeds growing under stress from previous herbicide applications.

f) Weed emergence after application
Precept Selective Herbicide will not reliably control following germinations of weeds. A follow up application of a suitable herbicide may be required to control remaining plants or plants that emerge after application. The use of Precept Selective Herbicide at 2 L/ha will provide better control of weed emergence following application.

4. Compatibility
Observe the more rigorous of the recommended crops and crop safety restrictions for the Precept and companion herbicide labels when tank mixing.
When mixing with other herbicides increased crop effects may occur. Under normal growing conditions this should not result in any yield loss due to Precept.

5. Crop Safety
Precept Selective Herbicide generally shows good crop selectivity when used as directed. The following will help minimise crop effects.

Selective crops
- DO NOT apply to crops undersown with legumes or to broadleaf pastures.
- DO NOT apply to any crop other than wheat, barley, oats, cereal rye or triticale.
- DO NOT apply to hay crops unless boom overlap growth reduction is accepted.
- DO NOT apply Ally plus Precept in oats.

Recommended growth stage
- Precept Selective Herbicide contains MCPA 2-ethylhexyl ester. Wheat, oat, triticale and cereal rye should be at minimum 3 leaf stage (Z13 growth stage), before application of Precept Selective Herbicide. Barley should be at minimum 5 leaf stage (Z15 growth stage), before application of Precept Selective Herbicide. Consult your local agronomist for the latest advice on varieties which require later growth stage applications to avoid the effects of MCPA.
- DO NOT apply later than Z31 (first node).

Agronomic and environmental factors
- Some crop yellowing and growth retardation may occur within 2 to 5 weeks of application. Where Precept Selective Herbicide up to 2 L/ha is applied, any effects will be negligible and rapidly dissipate except in areas of boom overlap. In boom overlap areas, growth retardation may occasionally remain until spring. Grain yield will not be compromised.
- Growth retardation and discolouration may be increased if the crop is affected by root disease, (e.g. cereal cyst nematode, rhizoctonia, take-all (haydie)), nutritional stress, waterlogging, drought stress, excessively cold conditions or previous herbicide treatment.
- DO NOT apply to cereals that are physically damaged (e.g. by hail, wind, insect attack).
- DO NOT apply to crops not actively growing, e.g. due to cold and wet conditions or drought stress.
- Crop effects (discolouration and slowed rate of growth) may be increased when Ally is tank mixed with Precept at 1.0 L/ha plus Hasten at 1% v/v. Under normal growing conditions this should not result in any yield loss. Observe crop safety restrictions on the Ally label.

6. Crop Rotation Recommendations
Minimum re-cropping intervals apply for all crops following Precept Selective Herbicide application.
Recropping intervals are dependent on the rate of product applied. Areas that receive double rates (boom overlaps) may show symptoms of damage in sensitive crops. This is generally restricted to discolouration (bleaching) of the crop but may also result in biomass reduction or reduced yields in some situations.

Rainfall/irrigation –winter and summer recropping
For crops listed as requiring a minimum amount of rainfall or irrigation in combination with a set recropping interval; rainfall and irrigation totalling less than the stated amount in the tables below following use of Precept may result in an extended recropping interval; patchy rain, with extended dry periods may also result in an extended recropping intervals, even when rainfall exceeds the minimum stated. If in doubt, seek specialist advice.
Dry conditions or less than the recommended minimum rainfall and irrigation
Where less than the minimum rain has fallen between application and planting the next year, it is recommended to only plant a cereal.
pH
Application to soils with a pH greater than 8.4 (soil in water) has not been tested and is not recommended.
Recropping symptoms are reduced on acid soils (pH < 6.5 soil in water, pH < 6.0 in CaCl2).
Tank mixture with other herbicides
In the event that a tank mixture of Precept and another herbicide has been used, the longer recropping interval of the tank mix products should be observed for the crop in question.

For winter recropping, transient biomass reduction or discolouration may occur where recropped following Precept application. When used as directed grain yield is not compromised where transient biomass reduction or discolouration occurs.
* Where Precept at 1 L/ha is applied on alkaline soils, recropped areas that receive double rates (boom overlaps) may show increased symptoms of damage in crops such as clover, faba bean and lentil. This is generally restricted to discolouration (bleaching) of the crop but may also result in biomass reduction or reduced yields in some situations.
**Where Precept at 2 L/ha is applied on alkaline soils, recropped areas that receive double rates (boom overlaps) may show increased symptoms of damage in crops such as canola, field pea, lentil, lupin, medic and vetch. This is generally restricted to discolouration (bleaching) of the crop but may also result in biomass reduction or reduced yields in some situations.

Crop - summer sown: Maize, sorghum

For summer recropping, transient biomass reduction or discolouration may occur where recropped after Precept application. When used as directed grain yield is not compromised where transient biomass reduction or discolouration occurs.
***Where Precept at 2 L/ha is applied, recropping areas that receive double rates (boom overlaps) may show increased symptoms of damage. This is generally restricted to discolouration (bleaching) of the crop but may also result in biomass reduction in some situations.

Resistant Weeds Warning
Precept Selective Herbicide contains members of the pyrazole (pyrasulfotole) and phenoxy (MCPA) groups of herbicides. Precept is a herbicide which inhibits 4-hydroxyphenylpyruvate dioxygenase (4-HPPD) and also acts by disruption of plant cell growth. For weed resistance management Precept is a Group H and Group I herbicide. Some naturally-occurring weed biotypes resistant to Precept, and other Group H and Group 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 may not be controlled by Precept or other Group H and Group I herbicides.
Since occurrence of resistant weeds is difficult to detect prior to use, Bayer CropScience Pty Ltd accepts no liability for any losses that may result from the failure of Precept to control resistant weeds.
Do not rely exclusively on Precept for weed control. Use as part of an integrated weed management program involving herbicides with other modes of action and non-chemical methods of control. CropLife Australia resistance management strategies are available from your local agricultural chemical supplier. Refer to these strategies for details of how to manage the build up of resistant weeds on your farm.
