Abstract
Free hydrazine and its salts with various organic and inorganic acids have slight pesticidal activity and are not used in agriculture. Only the double salt of copper sulfate with dihydrazine sulfate, which has been proposed for control of powdery mildew and black spot of roses, has some practical importance. The action of this compound apparently is based on reduction of copper sulfate by hydrazine to cuprous oxide and the free metal. The compound is a light blue powder, slightly soluble in water. The LD50 for rats is 590 mg./kg. It is marketed in the form of a 50% wettable powder that is used at a concentration of 0.3–0.4%.
