| الوصف: | The study aimed to evaluate the efficiency and the quality of technology application of the tank mixture of glyphosate + carfentrazone-ethyl in Commelina diffusa control. The experiment was conducted in plastic greenhouse and the experimental units were represented by vessels with four plants of C. diffusa. The experimental design was the entirely randomized, with nine treatments in a factorial scheme (4x2)+1, being four spray nozzles, (XR11002; DG11002; TT11002 and AI11002), two spray solutions of glyphosate + carfentrazone-ethy at 480 + 8 g ha - 1 (with and without Triunfo Flex TM adjuvant at 0.05% v v - 1 ) and a check without application. In the spray solution was added the FD&C-1 dye (1500 ppm), and applied over natural (15 replications of four leaves of C. diffusa ) and artificial targets (4 replications of two plastic blades over the soil). The tracer quantification on the targets was realized by spectrophotometry, beyond evaluated the pH, static surface tension and conductivity of the solutions and control of C. diffusa at 5, 10 and 15 days after application. The Triunfo Flex TM adjuvant reduced the surface tension and the pH of carfentrazone-ethyl + glyphosate mixture. There was significant interaction between nozzles and glyphosate + carfentrazone-ethyl solution with the adjuvant for the deposit on the leaves of C. diffusa. With the exception of TT11002 model, the other nozzles promoted significant increase of the deposition on C. diffusa when combined with the adjuvant. For solution deposition in plastic blades the best performances were characterized by DG11002 nozzle with and without adjuvant and AI11002 nozzle with adjuvant. The initial control of C. diffusa with glyphosate + carfentrazone-ethyl was improved when associated with the adjuvant, mainly for AI11002 and TT11002 nozzles. |
