Vaster Green Dichlorvos is available in the market under the brand name Dedevap 50%EC. Dichlorvos is a non-systemic and penetrating insecticide with a touching, digestive and respiratory (smoking) effect and a strong shock effect, with a short protective period. This compound has a high egg-removing effect, but due to durability and low residue on the crops, it acts weaker on micticides than other insects. The effect of this pesticide is to inhibit the cholinesterase enzyme in the nervous system of animals. Acetylcholine acts as a nerve message carrier in the intersynaptic space and stimulates the next axon. Dichlorvos causes the accumulation of acetylcholine in the synapse in the insect body, and as a result, the stimulation of the next nerve fiber continues continuously, and this is because the cholinesterase enzyme necessary to break down acetylcholine in the intersynaptic space and eliminate this continuous stimulation is blocked by dichlorvos. This pesticide, belongs to the group of organophosphorus compounds (phosphoric acid derivatives), which is formulated non-systemically, with a touching, digestive, respiratory (smoking) and infiltration effect in the form of an emulsion (50% EC). The solubility of this compound in water at a temperature of 25 degrees of Celsius is about one percent. Dichlorvos hydrolyzes in a humid environment and produces phosphoric acid. The half-life (DT50) of this compound is three days (36 hours) at a temperature of 25 degrees of Celsius and pH: 8. Dichlorvos is hydrolyzed gradually in water and acidic environments, but is hydrolyzed rapidly in alkaline environments.
