Postharvest control of diapausing two-spotted spider mite Tetranychus urticae Koch on fruit. II. Efficacy of Pulse on apples.

The efficacy of Pulse (oxyalkylene methyl siloxane) combined with chlorine for the control of Tetranychus urticae on apples was studied. More than 96% of diapausing mites which had not spun webs were removed from apples when dipped in water or Pulse. There was no relationship between Pulse concn and percentage of mites removed. Thirty-nine to 65% of diapausing mites were removed when apples on which webbing was established were dipped in 1.25% Pulse and complete control of the remaining mites was achieved. This paper was presented at a conference held in Wellington, New Zealand, on 11-13 August 1992.
