ABSTRACT.- Fusarium head blight (FHB) is a destructive disease of cereal grains caused by several Fusarium species, of which Fusarium graminearum is considered the primary causal agent. In this work 586 pure cultures of Fusarium spp. were obtained from infected grains, of which 64.9% belonged to the Fusarium graminearum species complex. 96.4% of those isolates had 15-acetyldeoxynivalenol genotype and the rest exhibited Nivalenol genotype. The second most predominant species was F. poae (19.1%) followed by F. avenaceum (8.2%) and F. tricinctum (4.6%). An increase in the tolerance to tebuconazole of Uruguayan Fusarium spp. isolates was detected.© 2022 Informa UK Limited, trading as Taylor & Francis Group |

Abstract: Barnyardgrass [Echinochloa crus-galli (L.) P. Beauv] is the foremost weed in rice (Oryza sativa L.) systems and its control is crucial to successful rice production. Quinclorac, a synthetic auxin herbicide, has been used effectively to manage E. crus-galli. However, the occurrence of quinclorac-resistant genotypes are frequently reported, and its resistance evolution has questioned the continued utility of quinclorac for grass control. Identification of the resistance mechanism(s) of resistant genotypes will facilitate development of integrated weed management strategies that sustain quinclorac use for management of E. crus-galli. We evaluated the responses to quinclorac of two contrasting genotypes: E7 (resistant, R) and LM04 (susceptible, S). Quinclorac induced ethylene and cyanide biosynthesis in the S-genotype. Both genotypes responded similarly to an increasing application of exogenous 1-carboxylic acid aminocyclopropane (ACC) and potassium cyanide (KCN), and their growth was inhibited at higher doses. The key mechanism for cyanide (HCN) detoxification in plants, β-cyanoalanine synthase (β-CAS) activity, was evaluated in both genotypes, and no significant difference was observed in the basal activity. However, quinclorac significantly induced β-CAS-like activity in the S-genotype, which is consistent with the increased synthesis of ethylene and cyanide. This work suggests that the resistance to quinclorac of the E7 R-genotype is likely related to an alteration in the auxin signal transduction pathway, causing a lower stimulation of ACC synthase and, therefore, limited synthesis of ethylene and HCN after quinclorac treatment.
