         Bendiocarb was evaluated in 1982, at which time a temporary ADI
    was estimated and a number of temporary MRLs proposed.1/ In the
    absence of information on the use of bendiocarb on a number of
    commodities in good agricultural practice, it was recommended that the
    status of all MRLS (except maize, maize fodder and forage, sugarbeet
    and sugarbeet tops) should remain temporary, regardless of the status
    of the ADI, until information on good agricultural practice was

         Information has been provided on nationally approved uses of
    bendiocarb on potatoes and rice, together with supporting residues



         In Canada, bendiocarb is currently registered for use in
    dwellings, food processing plants, food service establishments and
    food transport vehicles; limitations include the absence or adequate
    protection of food when treatment is undertaken.


         In West Germany the use of bendiocarb as a 20 percent W.P.
    formulation (20W) was registered in 1981. The dose rate is 0.12 kg
    a.i./ha (0.6 kg/ha of product) with a recommended withholding period
    of 14 days.


         The use of a 40 percent powder formulation (40W) in Taiwan
    province of China was registered in 1982, with a dose rate of
    0.4 - 0.48 kg/ha and a withholding period of 15 days.

         In Japan, the use of a 5 percent granular formulation in rice
    seedling boxes was approved at dose rates of 3-5 g a.i./box (5 1 of
    soil) applied at the transplanting stage.

         Use patterns of bendiocarb in the Republic of Korea are
    summarized in Table 1.

    Nursery rice               10-14 days after seeding                 3
    Hand-transplanting rice    Less than 7 days after puddling          4
    Barley                     After seed moulding                      4
         The application method in rice consists in maintaining the level
    of paddy water at about 3-4 cm deep for 3-4 days after the pesticide
    application, both in the nursery and the growing field.

         For barley, the recommended portions of the pesticide are
    uniformly applied on upland or drained paddy field, followed by
    sufficient seed moulding of more than 2-cm soil depth.


         Data on bendiocarb residues resulting from supervised trials on
    grain, rice straw and other crops in the Republic of Korea are
    reported in Table 2.


         The meeting reviewed the residues data on rice from the 1982
    evaluations in the light of new information on good agricultural
    practice. The proposed temporary MRL of 2 mg/kg for rice in husk was
    based on trial conditions which are not reflected in any current
    nationally approved agricultural practices. Accordingly, the meeting
    agreed to withdraw this estimate and replace it with an estimated
    maximum residue level of 0.02 mg/kg for de-husked rice.

         The meeting also received information on the use of bendiocarb on
    potatoes in the Federal Republic of Germany and agreed that it
    satisfied the requirement of the 1982 meeting for that crop.


         The following maximum residue level was estimated and recommended
    as suitable for use as temporary MRL. It remains temporary until the
    information on GAP required by the 1982 JMPR is provided.
