TRANSLOCATION OF FENOXYCARB IN THE AGROECOSYSTEM

With the aim to ascertain the possibility of diffusion of fenoxycarb in the agro-ecosystem, investigations were done in a greenhouse of about 40 m(3) in which two-year-old mulberry plants mere growing. A mater solution of the commercial product Insegar (2.0 gl(-1)) mas poured in Petri dishes for a total area of 6,104 cm(2). The air inside the greenhouse was collected by a suction pump when 1/3 of the solution evaporated. It contained 3.56 mu g m(-3) of fenoxycarb. As soon as the solution evaporated completely, the mulberry leaves were collected and washed with mater. This water contained 390 mu g of fenoxycarb kg(-1) of leaves. The leaves, dried in the shade and analyzed 15 months after collection, contained 13 mu g kg(-1) of fenoxycarb.
