ABSTRACT
We cannot describe all aspects of pesticides as environmental hazards, but we intend to address certain aspects of this problem; many books are available (Carson, 1962; Ecobichon, 2001; Edwards, 1973; Emden, 1996; Graham and Wienere, 1995; Mellanby, 1970; Ratcliff, 1967; Walker et al., 1996). It is also easy to find opinions and facts on the Internet. Our problem is that we meet people who believe that cigarette smoking causes cancer because the tobacco plants are sprayed with insecticides and who at the same time are convinced that food produced without pesticides is always safe. We are therefore often engaged in debates as defenders, and not as critics, to the unnecessary and unsafe use of pesticides, as we should be. But pesticides are poisonous to man, animals, plants, and sometimes to all types of life, as many of us have experienced.
