Abstract

The persistence of toxic effects of the contact acaricides dicofol, propargite, and formetanate HCl and the ovicides clofentezine and hexythiazox to the European red mite, Panonychus ulmi (Koch), were tested by bioassays of disks cut from treated peach foliage. Effects of dicofol were more persistent than propargite or formetanate HCl to susceptible mites. Mortality on dicofol-treated foliage was >50% for more than 15 days. Propargite killed >50% of females for 10 days after application, whereas the toxicity of formetanate HCl deposits declined rapidly after 7 days. Mortality of dicofol-resistant mites was less than for susceptible mites. However, resistant mites were affected (>50% killed) by dicofol residues up to 7 days old. The toxic effects of the ovicides clofentezine and hexythiazox persisted for at least 30 days and at the rates tested were approximately equally toxic.

Formetanate HCl and propargite residues were less persistent (half-life 8–9 days) than the other compounds. Dicofol residues had a half-life of about 15 days but approximately 10% of residues persisted for 65 days. Residues of clofentezine and hexythiazox declined more gradually (half-life = 15–20 days) than other compounds and persisted at approximately 10% of initial residues after 65 days.

Résumé

La persistance des effets toxiques des acaricides de contact dicofol, propargite et formetanate HCl, et des ovicides clofentézine et hexythiazox, sur le Tétranyque rouge du pommier, Panonychus ulmi (Koch), a été déterminée au cours d’expériences de dosage sur des disques prélevés à même des feuilles de pêchers. Les effets du dicofol sont plus persistants que ceux des autres acaricides, propargite et formetanate HCl, chez les acariens sensibles. La mortalité sur le feuillage traité au dicofol est supérieure à50% durant plus de 15 jours. La mortalité des femelles est supérieure à50% durant 10 jours après l’application de propargite, alors que la toxicité des dépôts de formetanate HCl diminue rapidement après 7 jours. La mortalité chez les acariens résistants au dicofol est moins élevée que celle qui prévaut chez les acariens sensibles. Cependant, les acariens résistants sont tout de même affectés (plus de 50% tués) par les résidus de dicofol pour une durée de 7 jours. Les effets toxiques des ovicides clofentézine et hexythiazox persistent pour au moins 30 jours et, aux doses employées, ces produits ont à peu près la même toxicité.

Les résidus de formetanate HCl et de propargite sont moins persistants (demi-vie 8–9 jours) que les autres produits. Les résidus de dicofol ont une demi-vie d’environ 15 jours, mais environ 10% des résidus peuvent persister jusqu’à 65 jours. Les résidus de clofentézine et d’hexythiazox diminuent plus progressivement (demi-vie = 15–20 jours) que les autres produits et environ 10% des résidus initiaux persistent plus de 65 jours.
