GENERAL INSTRUCTIONS
RESISTANT WEEDS WARNING
BRONCO® 200 Herbicide is a member of the Nitrite group of herbicides. BRONCO 200 has the photosystem II inhibitor mode of action. For weed resistance management BRONCO 200 is a Group C herbicide.
Some naturally-occurring weed biotypes resistant to BRONCO 200 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 BRONCO 200 or other Group C 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 BRONCO 200 to control resistant weeds. However resistance should not be assumed without first viewing the method of application, the coverage and the timing of application.

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.

APPLICATION
BOOM SPRAYER: Apply 50 to 200 (WA: 50 to 100) litres of water per hectare. Calibrate the machine before use to ensure that the correct application rate is obtained. Check height of boom above the crop to ensure that the spray is evenly distributed. A minimum of 160 litres and preferably 200 litres of water per hectare is recommended where the weed infestation is heavy or the crop cover is dense. Wash the sprayer thoroughly after use with clean water.
AERIAL APPLICATION: Apply a minimum of 22 litres of water per hectare. Markers should always move upwind before the aircraft passes overhead. Application by micronaire equipment may give variable results.

COMPATIBILITY
This product may be mixed in the spray tank with one of the following herbicides or insecticides according to the directions of use of this product: Chlorpyrifos, Dicamba, Dimethoate, Endosulfan, Diclofop-Methyl, MCPA, Omethoate and 2,4-D Amine.
As formulations of other manufactures’ products are beyond the control of Adama Australia Pty. Ltd. all mixtures should be tested prior to mixing commercial quantities.
