It is a colorless-light yellowish viscous liquid at room temperature and easy soluble in h2o. It is of the excellent properties of wetting penetration, emulsion, dispersion and synergist. It can raise the activity of paraquat by decreasing the surface tension significantly, increasing the affixing ability between the drops of the liquid and the surface of the leans promoting the pesticide into the plant. It less using amount and good viscidity reduces the amount of paraquat and the cost of the pesticide. It is safe nontoxic and environment friendly. It is of the excellent properties of wetting penetration, emulsion, dispersion and synergist the standardize of environment 200kg/plastic drum
Paraquat is a toxic chemical that is widely used as an herbicide (plant killer), primarily for weed and grass control. In the United States, paraquat is available primarily as a liquid in various strengths.
Chemical 2,4-D Structure Formula Common Name 2,4-D (BSI, E-ISO, (m) F-ISO, WSSA); 2,4-PA (JMAF) CAS No. 94-75-7 CAS Name (2,4-dichlorophenoxy)acetic acid Molecular Formula C8H6Cl2O3 Agrochemical Type Herbicide,phenoxycarboxylic acids Mode of Action Selective systemic herbicide. Salts are readily absorbed by the roots, whilst esters are readily absorbed by the foliage. Translocation occurs, with accumulation principally at the meristematic regions of shoots and roots. Acts as a growth inhibitor. Characteristics and Uses Post-emergence control of annual and perennial broad-leaved weeds in cereals, maize, sorghum, grassland, established turf, grass seed crops, orchards (pome fruit and stone fruit), cranberries, asparagus, sugar cane, rice, forestry, and on non-crop land (including areas adjacent to water), at 0.28-2.3 kg/ha. Control of broad-leaved aquatic weeds. The isopropyl ester can also be used as a plant growth regulator to prevent premature fruit fall in citrus fruit. 2,4-D 98% TC Items Standards Appearance White loose powder, free from visible extraneous matter Content of a.i. 98 % Loss on drying 1.5% Triethanolamine insolubles 0.5% Free phenol(as 2,4-dichlorophenol) 0.3% 2,4-D 72% SL ITEMS STANDARDS Appearance Brown transparent liquid free from visible extraneous material.

Paraquat - weedfast Common name: paraquat Cas no.: 1910-42-5 Molecular formula: c12h14n2.2cl Activity: herbicide Ingredient: 42% tc Formulation: 20% sl Mode of action: Non-selective and quick-acting herbicide which kills a wide range of annual grasses and broad-leaved weeds and the tops of established perennial weeds. It is redistributed within the plant, but does not harm mature bark. It becomes biologically inactive upon contact with soil. It is also used as a defoliant on crops, like cotton, prior to harvest.
