DESCRIPTION
|
During photosynthesis superoxide generated, which damages cell membranes and cytoplasm.
|
Mode of action
|
Non-Selective contact herbicide, absorbed by the foliage, with some translocation in the xylem.
|
Applications
It is broad spectrum, non selective & contact herbicide containing 24% Paraquat dichloride A.I which effectively controls broadleaved weeds & grasses.
It is absorbed by foliage with some translocation in xylem.
An ideal herbicide for conservation and no-till system (only controls the foliage parts of weeds) thus promoting intact roots and preventing soil erosion.
It is used as post emergence directed application & pre-plant application in many crops.
It damages cell membranes & cytoplasm during photosynthesis by producing superoxide.
