GENERAL INFORMATION
Bonanza Elite is a selective herbicide for the control of a range of broad leaf weeds in winter and spring sown cereals (except oats). Bonanza Elite has both contact and residual activity. It is absorbed by the roots and shoots of germinating seedlings, where it inhibits biosynthesis of enzymes critical to photosynthesis.

DIRECTIONS FOR USE
Caution: Bonanza Elite should not be used on Oats. Bonanza Elite can damage grass and clovers. Do not use on undersown cereals, on oats, or on other cereals not listed on this label. Do not use on soil with high organic content (>10%). A slight yellowing of the crop may be apparent with lighter soils or under cool or wet conditions. However, this is temporary, and will not have any lasting effect on the crop. Do not use with crop oils. Thoroughly clean equipment after use. R

ATES AND TIMING OF APPLICATION
Avoid spraying when rain is expected. Rain within 6 hours of treatment may reduce effectiveness. Avoid spraying under drought conditions, or if severe frosts are expected.

CEREALS (Winter and spring sown wheat, barley, rye and triticale)
Rate per hectare: 200 mL/ha with 1L/ha of Isoproturon 500SC
Timing: Apply between early post emergence of crop and jointing. Apply before weed development progresses beyond stages described below. See Weeds Controlled and Additional Information below.

WITHHOLDING PERIODS
NOT REQUIRED WHEN USED AS DIRECTED.

Weeds Controlled
Up to 1 leaf stage – Cleavers, fumitory.
Up to 2 leaf stage – broad-leaved dock, cornbind, dandelion, fathen, scentless chamomile, small-flowered buttercup, sowthistle, vetch, willow weed, wireweed, yellow gromwell.
Up to 4 leaf stage – Black nightshade, catchfly, chickweed, field pansy, henbit, hemp nettle, mouse eared chickweed, nettle, nipplewort, oxtongue, parsley piert, redroot, scarlet pimpernel, scrambling speedwell, shepherd’s purse, spurrey, twin cress, wild turnip.

Older stages of weeds than specified above may only be severely checked or suppressed. Perennial weeds, especially those growing from root chips, will not be controlled. A mixture of Bonanza Elite 200 mL/ha, isoproturon 500 SC 1 L/ha and Chlorsulfuron Herbicide 15 g/ha will give improved control of some weeds at growth stages at the upper limits given in the table or where soil moisture conditions are less than optimal. A mixture of Bonanza Elite 200 mL/ha, isoproturon 500 SC 1 L/ha and 20 g/ha tribenuron-methyl 500 SG (Barley only) will give improved control of some weeds at growth stages at the upper limits shown under Weeds Controlled. Observe label directions for both products. Do not tank-mix with other herbicides or emulsifiable concentrate formulations of other pesticides.

Additional information:
A well prepared seedbed is important for optimum activity: all trash and ash should be buried and the final seedbed should be fine, well compacted and free of clods greater than 5 cm in diameter. Soils should be moist at and after application: weeds growing under moisture stress will be less susceptible to treatment. Dry conditions will reduce activity. Ensure that the crop is evenly drilled to a depth of 2.5 cm and that the seed is well covered. Failure to do this may result in transient crop yellowing. When applying Bonanza Elite, care should be taken not to overlap spray swaths or overdose when starting, slowing or stopping the sprayer, since crop damage may occur. After harvest thoroughly cultivate soil treated with Bonanza Elite before sowing a following crop. Following treatment with Bonanza Elite, in the event of a crop failure due to climate, pest or disease, redrill in the spring with wheat or barely only, after thorough cultivation has taken place.

APPLICATION METHODS
Bonanza Elite can be applied with conventional boom spraying equipment. Apply in 100 – 300 litres of water per hectare. Aerial spraying is not recommended. Application should be on to a freshly prepared seedbed with fine, compact, moist soil, and free of trash and clods greater than 5 cm.

MIXING
Bonanza Elite mixes readily with water. To ensure a uniform solution pour the correct amount into the partly filled tank and add the remainder of the water while agitating. Agitate thoroughly before and during spraying and before spraying after a stoppage.

COMPATIBILITY
Bonanza Elite is ideal as a tank mix partner in extending the spectrum of weed control when used with other herbicides. Bonanza Elite can be used in combination with herbicides such as isoproturon, tribenuron-methyl and Chlorsulfuron Herbicide. Do not mix with emulsifiable concentrate formulations. It is always recommended that a test mixture should be applied to check for crop damage before use. For further advice, contact your ADAMA New Zealand representative.

SOIL RESIDUES
Soil residues will persist for a while after spraying. Thoroughly cultivate before sowing the next crop.
