【 摘 要 】

The objective of this study was to evaluate the effectiveness of the glyphosate + quizalofop-p-tefuril in tank mixture with multifunctional adjuvants or oils for the control of RR ®corn. The experiment was conducted over greenhouse conditions. The treatments were arranged in a factorial design 11 x 2, with six replications. The treatments consisted of factor A, applying glyphosate + quizalofop-p-tefuril (1080 g a.e. + 36 g a.i. ha -1- T1) and associations of this with adjuvants, at doses of: 150 mL ha -1TA-35 ®(T2); 150 mL ha -1Orobor N1 ®(T3); 300 mL ha -1LI 700 ®(T4); 100 mL ha -1Triumph Flex ®(T5); 100 mL ha -1AllerBiw ®(T6); 1000 mL ha -1Fulltec ®(T7); 1000 mL ha -1Joint Oil ®(T8); 1000 mL ha -1Aureo ®(T9); 1000 mL ha -1Assist ®(T10); plus a check without application (T11), and the factor B, corn hybrids DKB 240 RR PRO2 ®and DKB 245 RR ® . The hybrids showed distinct symptoms at 7 days after application, regardless of the adjuvant used. DKB 240 RR PRO2 ®presented chlorosis, onset of necrosis of the edges of the leaves and only a few plants with reddish pigmentation, different from DKB 245 RR ® , where there was more widespread reddening and necrosis of tips and edges of the leaves. No significant differences were observed in control of the hybrids using glyphosate + quizalofop-p-tefuril, associated with multifunctional adjuvants, mineral and/or vegetable oils.
