ABSTRACT:
The present invention relates to a stable azinphos-methyl wettable powder formulation. The composition of the present invention contains an insecticide powder formulation and a magnesium sulfate heptahydrate. The magnesium sulfate heptahydrate is added to the azinphos-methyl formulation in an amount such that the magnesium sulfate heptahydrate is from about 5% by weight to about 20% by weight of the total mixture. The addition of the magnesium sulfate heptahydrate reduces deflagration of the azinphos-methyl formulation and reduces the tendency of exothermic decomposition to occur.
