The Control of Common Red Spider and Thrips by the Use of N,N Amyl Benzyl Cyclohexylamine*

Abstract

Study of the insecticidal properties of derivatives of cyclohexylamine resulted in the. discovery that N,N amyl benzyl cyclohexylamine, a water-immiscible liquid, is highly toxic to red spider and thrips. Its toxicity is greatly influenced by the type of emulsifier and the ratio of emulsifier to toxicant employed. A formulation consisting of 70% N,N amyl benzyl cyclohexylamine and 30% of Santobane A Emulsifier doubled the toxicity of the compound as previously reported by Compton & Kearns (1937) for red spider infesting roses. This emulsion was shown by laboratory and practical tests in commercial greenhouses to be effective against red spider and thrips on several greenhouse and ornamental crops.
