Contenido :  ABSTRACT.- Herbicide resistance in Conyza bonariensis (hairy fleabane) poses a significant challenge to agricultural systems worldwide. The genetic variability and prolific seed production of this species contribute significantly to its adaptative potential and fast spread in the agricultural fields. This study aimed to investigate the mechanisms underlying multiple herbicide resistance to glyphosate and ALS inhibitors in C. bonariensis biotypes from southern Brazil. Resistance factors exceeded 100 times for chlorimuron-ethyl and 49 times for glyphosate. DNA Sequencing revealed the target-site mutations Pro106Thr in the EPSPS gene conferring glyphosate resistance, and Pro197Arg and Trp574Leu in the ALS gene contributing to chlorimuron-ethyl resistance. Additionally, the resistance factor decreased at least 80 % for resistant biotypes after application of chlorimuron-ethyl following treatment with the P450 inhibitor malathion, which might indicate enhanced metabolism mediated by cytochrome P450 enzymes. Copy number variation and overexpression of ALS and EPSPS genes were not related to resistance. Biotype II carries the Pro197Arg mutation and exhibited cross-resistance to imazethapyr, diclosulam, bispyribac‑sodium, and flucarbazone‑sodium. Biotypes carrying the Trp574Leu mutation were resistant to imazethapyr, diclosulam and flucarbazone-sodium but demonstrated varying resistance patterns to bispyribac-sodium, highlighting the complexity of resistance mechanisms. ... Presentar Todo

Contenido :  ABSTRACT. - Short-term solutions like increasing N fertilization and decompaction with deep tillage (DT) have been proposed to mitigate soil degradation in continuous cropping systems. However, the joint evaluation of these factors in established no-till systems is limited. This work aims to quantify corn yield losses generated by the cumulative degradation of soil quality of intensified no-till cropping systems, quantify to what extent yield losses could be mitigated by soil DT and N fertilization, and identify the most important process involved in yield reductions. Eleven experiments were installed during 2014 and 2015, on a typic Argiudoll with different soil quality generated by more than 50 years of contrasting land uses. A split-plot design was employed; the main plots were for DT (with and without) whereas the subplots were four N rates (0, 60, 120, and 240 kg ha?1). Overall, soil physical quality (SPQ) and carbon losses were associated with yield depletions. An increase in bulk density of 0.1 g cm?3 was associated with a 15.8% yield decrease. Deep tillage improved SPQ and modified water and N dynamics. However, these changes were small, variable, and did not affect corn growth. N fertilization improved yields but did not eliminate differences linked with land degradation and previous crop effects. Soil organic carbon had a better association with yields than bulk density, macroporosity, and penetration resistance. The results of this study highlight the importance o... Presentar Todo
