Abstract:
The use of substances helping in production is a technological that has studied in diversity crops, the sugarcane it is not different. The iam of this work was investigate the effect of thiametoxam in ratoon of sugarcane, in areas was applied with ripener trinexapac–etilico, about the quality of plants de sugarcane, development and productivity of stalks. The studys was development in three different citys in estate of São Paulo; Olimpia (A), Igaraçu do Tietê (B) e Macatuba (C), the experiment was block randomized with five repeats, the installments was constitude of tem liners of twenty five meters. The used doses were, respectively: thiametoxam 100 g i.a. ha-1, trinexapac-etilico 200 g i.a. ha-1 (0,8 L p.c.), active ingredients doses (commercial).For the experiments carried out in the beginning of crops we used the sugarcane variety RB855453 (early ripeness); for the experiments carried out in the end of crops we used the variety SP 80-3280, which is characterized for having late ripeness; for the products application, we used the pressurized coastal equipment (CO2) and for the application of thiametoxam there was an application through directed jet on the line of ratoon. The results were submitted to the LSD test, 5 % of probability. The application of thiametoxam in regrowths of sugarcane with the application of ripener enabled the following conclusions. The use of trinexapac-etilico whit ripener in successive bearing provides of increased of stalks number, but did not of increased productivity of stalks. The thiametoxam not change at industrial quality of sugarcane, however can increased stalks number, heights, plant and productivity of stalks and sugar.
