N- thiocarbamic

As In the case of the examples given in Tables I and III, the N-thiocarbamate derivatives were generally equal to the parent methylcarbamate in toxicity to house flies, particularly after taking into consideration Increase in molecular weights. Except for the methomyl and oxan l derivatives, substantial improvement in mosquito larvlcldal activity again appeare d to be a function of the lipophilic properties of the derivative. With the exception of the oxanyl derivatives, the data clearly indicate that the N-thiocarbamate derivatives are markedly less toxic to the white mouse than the parent methylcarbamate. Since...
