Uses
Sodium pentachlorophenolate (CAS NO.131-52-2) as a non-selective contact-type herbicide, pre-harvest defoliants, wood preservatives, can also be used to kill schistosome intermediate host snails, schistosomiasis prevention and treatment. As a herbicide, the main dividing weed seed propagation is a very broad range of anti-herbicide, which is mainly used for paddy fields. Used to kill snails, at 25 ℃, 10ppm flower liquid make 96.7% of the snails died, half-lethal concentration of 2ppm.
