Abstract

The aim of this research was to evaluate the effect of high dilutons (12CH) of Calcarea carbonica and Natrum muriatcum, compared to the essental oil of citronella, Cymbopogon nardus (L.) at 0.1%, on the incidence of thrips, Thrips tabaci Lind. (Thysanoptera: Thripidae) and onion yield under organic producton system. The experiment was carried out at Epagri’s Ituporanga Experiment Staton, in Ituporanga, SC, Brazil. The cultvar used was Epagri 362 Crioula Alto Vale. The experimental design was a randomized complete block with four replicatons. The treatments were sprayed at a concentraton
of 0.1% in water. The average incidence of thrips and the yield were not influenced by treatments.
