Chemical name: 1,1'-dimethyl-4,4'-bipyridinediium; 1,1'-dimethyl-4,4'-bipyridinium; 1,1'-dimethyl-4,4'-bipyridylium

CAS Number: 4685-14-7

Molecular formula: C12H14N2 

Appearance: Blue-green homogeneous liquid

Specification: 42%Tech, 20%SL

Application: During photosynthesis, superoxide is generated, which damages cell membranes and cytoplasm. 

Mode of action: Non-selective contact herbicide, absorbed by the foliage, with some translocation in the xylem. 

Uses: Broad-spectrum control of broad-leaved weeds and grasses in fruit orchards (including citrus), plantation crops (bananas, coffee, cocoa palms, coconut palms, oil palms, rubber, etc.), vines, olives, tea, alfalfa, onions, leeks, sugar beet, asparagus, ornamental trees and shrubs, in forestry, etc. Also used for general weed control on non-crop land; as a defoliant for cotton and hops; for destruction of potato haulms; as a desiccant for pineapples, sugar cane, soya beans, and sunflowers; for strawberry runner control; in pasture renovation; and for control of aquatic weeds. For control of annual weeds, applied at 0.4-1.0 kg/ha. Formulation types: SL.
