In order to use an agrochemlcal in most countries, it must first be registered in that country.
Usually this registration requires the company marketing the chemical to submit environmental fate data.
These studies may involve the fate of the chemical in plants, animals, soils, water and alr, and routinely use radlolabelled agrochemicals.
Examples of typical studies will be cited emphasizing the characteristics of the experiment, the positions and type of radlolabel used, and the implications of the data obtained from the experiments.
Since agrochemicals are usually biologically active, it is a common practice to study the effect of the agrochemlcal on some property of the soil, plant or animal.
In these cases radiolabelled substrates other than the agrochemical are used and the fate of the substrates studied.
Radlolabelled experiments with plant callus and suspension cultures have contributed greatly to our knowledge of the fate of agrochemlcals in plants and these studies have influenced the development of species specific agrochemicals.

## Abstract A radioactive bromine analogue, 1:1:1βtrichloroβ2:2βdiβ(4βbromophenyl)ethane, of the insecticide DDT has been used to indicate the fate of DDT sprayed on to wheat grain which is subsequently milled, baked and fed to animals. ^82^Br of high specific activity was prepared in the Harwell p
