| Summary: | The objective of this research was to evaluate high dilutions of Sulphur on the incidence of onion thrips, downy mildew, chlorophyll content and yield of onion under organic production system. The study was carried out at Ituporanga Experiment Station of Epagri, Santa Catarina State, Brazil, from August to December of 2011, 2012 and 2013. Treatments were foliar sprays of 0.5% Sulphur at high dilutions 6, 12 and 30 CH (CH, hahnemannian centesimal scale) and untreated plot as control check. The experimental design was a randomized block design with four replications. The incidence and damage of onion thrips, reduction of the severity of downy mildew, chlorophyll index, total and commercial yield, bulb weight, postharvest conservation were not influenced by the treatments. |
