Does growth regulator associated with fungicideinterfere on productivity ofupland rice?

Management measures should be tested to increase the rice productivity, a staple foodthat is in increasing demand. The aim ofthis study was to evaluate the efficacy ofdifferent doses ofa plant growth regulator, ethyl-trinexapac, combined with the application of the fungicidesepoxiconazole + pyraclos...

description Management measures should be tested to increase the rice productivity, a staple foodthat is in increasing demand. The aim ofthis study was to evaluate the efficacy ofdifferent doses ofa plant growth regulator, ethyl-trinexapac, combined with the application of the fungicidesepoxiconazole + pyraclostrobin in reducing the height of rice plants to avoid lodging and increaserice yield. The experiment was conducted in a dystrophic Oxisol soil during two harvests(2010/2011 and 2011/2012). The study was arranged in a randomized block design, in a 4 × 2factorial scheme, with four replications. The factors considered were four doses oftrinexapac- ethyl(0, 25, 50, and 75 g ha-1active ingredient (a.i.)), with or without application offungicide (137.25 gha-1a.i.). The growth regulator caused a reduction in plant height in both harvests and affected thenumber of panicles per square meter in the second harvest. The fungicide had no effect on theproductivity and yield components ofthe crop.
