DDVP Synthesis Technology

Abstract

DDVP, with the common name dichlorvos, has an active ingredient, 2,2-dicWorovinyl dimethyl phosphate, which was flrst introduced by Ciba Geigy AG under the trademark "Nuvan" and by Shell Chemical Co. under the trademark ''Vapona''. In Korea, DDVP has been tested for five years but continuous evaluation has also been carried out in many countries of the world. DDVP has contact, stomach and breathing poison actions. It provides sure control of sucking, biting and mining pests such as aphids, spider mites, caterpillas and beetle larvae. On account of its very fast killing action and the relatively rapid rate at which it is broken down on the plant, it can be used safely on crops close to harvest. DDVP features good plant tolerance, but it is harmful to bees.
