The Organochlorine Insecticides,p-chlorophenyl)- 1, 1, 1 -trichloroethane). Pure .-DDT is a white, tasteless, almost odorless crystalline solid. It is practically insoluble in water but soluble in many organic solvents such as acetone, benzene, carbon tetrachloride, kerosene, diesel oil, etc. It is slightly soluble in alcohol (abo

Botanical Insecticides, for the reviews see Yamamoto 1965; Schmeltz 1971). The usefulness of this preparation was due to its content of the nicotine alkaloid which is present in tobacco leaves. In addition to nicotine, two other closely related compounds, i.e., nornicotine and anabasine, also have some insecticidal activi

Neonicotinoids and Nitrogenous Insecticides,thesis, extreme toxicity to mammals, and limited insecticidal spectrum. The mode of insecticidal action of nicotine was clarified by Yamamoto (Yamamoto et al. 1962; Yamamoto 1965) and many of the synthetic analogs of nicotine fitted with specific structural feature, required for nicotinoid action sh

Fumigants and Nematicides,low the soil surface. ., and . are important agricultural pest nematodes. To be effective, chemicals must have high volatility at room temperature. Hence, nematicides are generally gases or volatile liquids of comparatively low molecular weight enabling them to penetrate through soils. Nonvolatile n
