Sumario:The objective of this study was to evaluate entomopathogens and neem oil associated with silicon on the management of thrips, downy mildew and onion yield variables. The experiment was carried out at Epagri, Ituporanga Experimental Station, Santa Catarina State, Brazil. The transplanting and harvesting of bulbs were performed respectively on 08/17/2015 and 12/07/2015. The treatments were: Serenade® (Bacillus subtilis) 1%; Metiê® (Metarhizium anisopliae) 1%; Ballveria® (Beauveria bassiana) 1%; Fortneem® (0.12% w/w azadirachtin oil) 1%, used alone or associated with Bugran® (diatomaceous earth, composed of 98.58% SiO2) and control without application. The treatments and dosages used, independently of the addition of silicon, had no effect on the management of thrips, downy mildew and yield of onion.
