Crops and their products can be contaminated either by direct application of pesticides for the protection of insects, acarives, agents of plant diseases and/or weeds, i.e. as the result of growing them on the soil containing pesticide residues applied in previous years. For the protection of sugar beet in our country, 23 insectisides, 17 fungicides and 18 herbicides have been registered. The pre-harvest interval (PHI) ranges from 14 to 42 days i.e. they are provided by the time of application (PTA) whereas the pre-harvest interval for herbicides ranges from 30 to 91 days and is ensured by the application period. Based on the results from the literature and on their own studies, the authors are of the opinion that the residues of the applied pesticides in sugar beet protection in accordance with the principles of good agricultural practice will be significantly lower than the maximum tolerable ammounts and that at the level from 1/4 to 1/10 of MRL. IT is necessary to emphasize the necessity of MRL determination both in leaves and in sugar loaf.in case they are used as animal feed.
