one day, almost 90% of the residues were removed from the leaves. On rice
grains, the residues were higher on rough rice than on milled rice but tie decline
is faster on rough rice.
CONCLUDING REMARKS
In spite of limited resources, the Philippines has contributed to knowledge
on pesticide residues in the tropics. The studies reviewed in this paper confirm
:he assumption tht pesticide degradation is faster in the tropics than in
temperate countries. The existing local practices with regards to marketing and
food preparation could contribute further to reduction of residues. Since climatic
conditions play a major role in pesticide dissipation, PHI recommendations
should be made on a region-to-region basis.
Residue studies in the rice paddy ecosystem showed that paddy-reared fish
could bioaccumulate residues beyond allowable limits. This is a problem to
consider s:ince tie rice-fish culture is being promoted in Asia.
