weed management in onion:-
Oxyfluorfen and bromoxynil can only be used on young onions
Oxyfluorfen is complimentary to bromoxynil in onion; together they control a wider spectrum of weeds than either do alone. They are usually used in sequence about 1 week apart depending on the crop growth rate and weeds present, and the order in which they are applied may vary according to experience. They can also be tank-mixed, or the sequence strategy can be combined with the tank mix method. If tank mixing these two chemicals, use a sufficient spray volume per acre and closely follow the label to avoid crop injury. Oxyfluorfen is commonly used when the crop has 1.5 fully developed true leaves, followed by an application of both oxyfluorfen and bromoxynil at the 2- and 3-leaf stages.
