The toxicity and the physiological action of insecticides, fungicides, rodenticides, and herbicides on plants are of basic importance. The toxicity of treated plants to animals, and the toxicity of treated plants and animals to humans and to wildlife are of practical concern. A long-range consideration of the effect of sprays on both plant and human nutrition and its relation to public health is of direct concern. The hazards in field application and methods of protecting operators should be reported in detail and further research should be emphasized. 

For protection of public health, there must be some control of the experimental use of pesticide chemicals in obtaining data necessary for registration of a marketable product. Experimental use permits are issued under provisions, at 40 USC 136c, of the Federal Insecticide, Fungicide, and Rodenticide Act. Either temporary tolerance or an exemption can be granted with a permit. When the EPA takes such action, a notice is published in the Federal Register (Schultz, 1981).

This book examines the chemistry and mode of action of herbicides, insecticides, fungicides and plant growth regulators. It follows crop protection strategies from early discoveries to the present day, emphasising the biochemical targets of the compounds discussed. 

This response is absolute nonsense. Sweden had banned the herbicide amitrole and several bis-dithiocarbamate fungicides because of flawed scientific evaluations that misinterpreted thyroid tumors in rodents, known to lack relevance for humans, as indicators of a human risk associated with normal usage. In contrast to Sweden s action, IARC and the U.S. Environmental Protection Agency cleared all of them of suspicions of causing cancer at current exposure levels,45 and the EU has approved amitrole for general use. Sweden s Minister of the Environment, Kj ell Lars-son, has declared that Sweden will fight all the way to the European Court of Justice to stop reintroduction of these horribly dangerous pesticides.
