ABSTRACT: The intensive use of glyphosate can select resistant populations. This study aimed at evaluating the occurrence of glyphosate resistance in populations of D. insularis in agricultural areas. Three experiments were conducted in randomized block experimental design with four replications. The Resistance Degree (RD) was determined by a dose-response curve in the evaluated populations: Experiment 2012, São Camilo (R01 and R02) and Palotina (R03, R04 and S05-susceptible); Experiment 2013 Palotina (R06 and R12), Katueté/Paraguay (R07), Toledo (R08 and R10), Cascavel (R09), São Miguel do Iguaçu (R11), Dom Eliseu/Pará (S13-susceptible); Experiment 2015 Nova Aurora (R14), Iracema do Oeste (R15 and R16), Jesuitas (R17 and R18), Tupãssi (R19), Jotaesse... |

ABSTRACT: The objective of this study was to evaluate the chemical control of the species C. benghalensis and C. erecta with desiccants alone and mixtures, as well as the spreading of spray droplets on the leaf surfaces. The experimental design was completely randomized in a 2 x 16 factorial arrangement with four replications, totaling 32 treatments and 128 plots. The first factor is related to the species C. benghalensis and C. erecta and the second factor corresponds to the treatments carfentrazone-ethyl in doses of 15, 30, 60 g ha-1, which added 0.5% v v-1 adhesive spreader; glufosinate ammonium at doses of 100, 200, 400 g ha-1, added 0.5% v v-1 mineral oil; glyphosate at 240, 480, 960 g ha-1; carfentrazone-ethyl + glufosinate ammonium in doses of 100,... |
