Weeds resistant to herbicides are widespread worldwide. Fimbristylis miliacea (FIMMI) is one of the most troublesome weeds in rice fields in southern Brazil. Acetolactate synthase (ALS)-inhibiting herbicides are widely used to control weeds in rice. The continuous use of ALS-inhibiting herbicides has led to the evolution of herbicide-resistant FIMMI. The objective of this research was to characterize resistance patterns of ALS inhibitor-resistant globe fringerush biotypes using whole-plant dose-response assays. To confirm the resistance of FIMMI to ALS inhibitors, whole-plant bioassays were conducted in 2008 and 2009 at Universidade Federal de Pelotas. The experiment was a randomized complete block design, with four replicates consisting of three factors (biotype, herbicide and rate) in a 3 x 4 x 7 factorial arrangement. The ALS herbicides were bispyribac-sodium, pyrazosulfuron-ethyl, penoxsulam and imazethapyr + imazapic. A standard herbicide treatment, bentazon, was also included because all FIMMI biotypes are susceptible to bentazon. Plants at the six-leaf stage were sprayed with herbicide equivalent to 0, 1, 2, 4, 8, 16 and 32x the full herbicide doses for the resistant biotypes (FIMMI 10 and FIMMI 12) and 0, 1/32, 1/16, 1/8, 1/4, 1/2 and 1x for the susceptible biotype (FIMMI 13). Herbicide treatments were applied using a backpack sprayer calibrated to deliver 150 L ha-1 at 200 kPa. The efficacy on F. miliacea was visually evaluated as % control at 7, 14, 21 and 28 days after treatment (DAT) and weight of dry biomass at 28 DAT. FIMMI 10-R biotype showed cross resistance to three chemical families of ALS-inhibiting herbicides (bispyribac-sodium, pyrazosulfuron-ethyl and penoxsulam). FIMMI 12-R biotype showed cross resistance to two (pyrazosulfuron-ethyl and penoxsulam) ALS herbicide families. Bentazon is still an effective alternative to control FIMMI in areas with ALS herbicide resistance. All biotypes did not show cross resistance to imidazolinones, i.e. the premix formulation of imazethapyr + imazapic. MenosWeeds resistant to herbicides are widespread worldwide.
