PESTICIDE RESIDUES IN FOOD - 1981 Sponsored jointly by FAO and WHO EVALUATIONS 1981 Food and Agriculture Organization of the United Nations Rome FAO PLANT PRODUCTION AND PROTECTION PAPER 42 pesticide residues in food: 1981 evaluations the monographs data and recommendations of the joint meeting of the FAO panel of experts on pesticide residues in food and the environment and the WHO expert group on pesticide residues Geneva, 23 November-2 December 1981 FOOD AND AGRICULTURE ORGANIZATION OF THE UNITED NATIONS Rome 1982 ETHIOFENCARB Explanation Ethiofencarb was evaluated by the JMPR in 1977 and 1978*; a number of temporary maximum residue levels (MRLs) were proposed, including figures for beans and sugarbeet. Further data on these crops have become available and are summarized below. RESIDUES IN FOOD RESIDUES RESULTING FROM SUPERVISED TRIALS Sugarbeet Table 1 summarizes and combines residues data from two extensive trials in the Netherlands in 1979. Application was at 0.5 kg a.i./ha. TABLE 1.

Table 2 summarizes and combines results from six trials on beans with pod, all at rate of 0.45 kg a.i./ha, but using several formulated products. The mean results in Table 2 are the means of six samples analysed in duplicate. * See Annex II for FAO and WHO documentation. TABLE 2.
