ALL CLEAR
Chemical Properties Solubility : Water soluble • Belong to chemical family of Bipyridylium Reactivity Prole • Stable in acidic media, but unstable in alkaline media • Decomposes photochemically by UV radiation in aqueous solutions and is rapidly inactivated by soil • Sensitive to light • Corrosive to metal and react with strong acids, bases, and oxidizing agents • Hydrolyzed by alkali compounds • Inactivated by inert clays and anionic surfactants
Qualities • All clear is a contact, Non- Selective, post emergence herbicide • All Clear is used as foliar Spray to control broad leaf weeds and grasses • All Clear control all annual and certain perennial weeds • Wide usage in terms of crops like Corn, soya, wheat, rice, potatoes, fruit (oranges, apples, bananas), coffee, tea, cocoa, cotton, oil palm, sugar beet, sugarcane and rubber • An ideal herbicide for conservation and no-till systems (only controls the foliage parts of weeds), thus promoting intact roots and preventing soil erosion • Hydrolyzed by alkali compounds • Inactivated by inert clays and anionic surfactants
Mode of action • All Clear inhibits photosynthesis . • All Clear results in rapid disruption of cell membranes and kills rapidly. • All Clear penetrate into the cytoplasm, form peroxides and free electrons (light is required) which destroy the cell membranes almost immediately • Rapid destruction of cell membranes prevents translocation of energy to other regions of the plant • Severe injury is evident in few hours after application, rst as watersoaked areas which later turn yellow or brown • Maximum control is attained in a week • Partial spray coverage of a plant results in spotting or partial shoot kill • It is redistributed within the plant, but does not harm mature bark
Importance • All clear is strongly cationic and relatively toxic herbicide .It is very fast-acting, results appears with in week time. It is rain-fast within 15-30 minutes of application. • All clear is also effective under low temperatures when weeds are making little active growth. • All Clear do not penetrate mature bark, sprayed safely around trees and beneath bushes. • All clear has no ‘residual’ activity in soil, can be sprayed before crops are planted or seedlings emerge. • All Clear strongly bind to clay, preventing activity for weed control or leaching in the soil . All Clear solution with suspended colloids like muddy water, slurry, fertilizers etc will cause chemical inactivation. • All Clear is used for killing shoot in numerous situations like burn down in conservation tillage systems and pre-harvest desiccation.
