Critical comments: CROP STAGE
All Cereals
Apply from 3 leaf to fully tillered stage - Z13 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: TRIATHLON may cause transient crop yellowing of cereals (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.
TRIATHLON 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 14 day withholding period. Refer to ‘Protection of Livestock’ for grazing precautions.
WILD RADISH
TRIATHLON 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.
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.
# Where Wireweed occurs in red soils of low fertility it has been found to be less susceptible.

NOT TO BE USED FOR ANY PURPOSE OR IN ANY MANNER CONTRARY TO THIS LABEL UNLESS AUTHORISED UNDER APPROPRIATE LEGISLATION.

WITHHOLDING PERIODS
HARVEST: NOT REQUIRED WHEN USED AS DIRECTED.
GRAZING: DO NOT GRAZE OR CUT FOR STOCK FOOD WITHIN 14 DAYS AFTER APPLICATION.

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

CROP TOLERANCE
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. Some pre-emergent 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.

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 TRIATHLON 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 TRIATHLON 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.

COMPATIBILITY
DO NOT use crop oils with TRIATHLON or TRIATHLON 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.

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.
DO NOT use crop oils with TRIATHLON or TRIATHLON 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.
