The significance of plant metabolites of insecticide residues

摘要: The widespread use of insecticides and the necessity meeting tolerance limits has focused attention on importance extent duration toxic residues. process loss generally follows first-order reaction kinetics. There is an immediate rapid following application due to such factors as weathering then a much slower rate. When plotted semilogarithmically two distinct slopes result, been illustrated by Hoskins (1961). Gunther Blinn (1955 1956) (1962) have shown that this second or “degradation” slope can be followed even less steep one termed persistence curve. This last typical penetration into oily waxy layers where residue very slow (Matsumura 1960). Factors influencing well depositions, degradation, particularly formulation are reviewed in detail Ebeling (1963).
