Abstract

Sugarcane is grown in an agro-industrial model with a cyclelong production period. Harvesting is carried out over extended periods,subjecting the plant to different climatic conditions that affect the accumulation ofsugars, the main objective of its exploitation.This study aims to compare thepotential for sugar accumulation in sugarcane stalks when applyinga plant regulator based on trinexapaque-ethyl associated with azoxystrobin andcyproconazole. This combination is intended to temporarily influencein plant respiration, with the aim of identifying its effects on the synthesis ofsucrose.This work will be carried out at the beginning of the harvest, with 4treatments and 5 repetitions in Randomized Blocks (DBC), in a factorial scheme2X2, the first factor being a Maturator based on ethyl trinexapaque; and thesecond, a fungicide based on azoxystrobin and cyproconazole with fiverepetitions, totaling 20 experimental plots.They will be evaluated at the momentapplication of the products - day 0 to 60 days, every 15 days: the rate ofgrowth in Tons of Culms per hectare through biometrics andtechnological parameters for determining sugarcane Brix, sugarcane Pol, ARSugarcane, Purity, Moisture and ATR. Variance analysis of the data will be carried out at 5%probability in order to evaluate differences between treatments (SAS).
