ABSTRACT.
The in vitro and in vivo control of Phyllosticta citricarpa (citrus black spot, CBS) on citrus fruits was evaluated using 14 essential oils (EOs) extracted from Uruguayan native plants. In vitro, volatile components of Chenopodium ambrosioides completely inhibited fungal growth. The dilution agar test showed that fungus reproduction was completely inhibited by Conyza bonaerensis essential oil (EO). The other 12 EOs tested showed high inhibition after 10?15 d, presenting fungistatic effects. In vivo, assays were performed on fruit of lemon [Citrus limon (L.) Burm] and Valencia orange [Citrus sinensis (L.) Osbeck] in order to evaluate the effects of liquid and volatile EO phases on reproduction. Typical lesions of CBS without reproductive structures were exposed to Ch. ambrosioides and C. bonaerensis EOs for 20 d at 27 C and cycles of 16 h light and 8 h dark. The volatile components of Ch. ambrosioides were able to control 100% of P. citricarpa reproduction in orange and lemon fruit. The growth of other fungi such, as Colletotrichum gloeosporoides and Fusarium sp., was also inhibited. Nevertheless, the liquid phase was not effective to control the pathogen. In another test, carton boxes with 20 fruits, each presenting typical CBS
symptoms, but without the presence of reproductive structures, were exposed to 0.01 and 0.05% of Ch. ambrosioides EO (w/v). The fruits were stored at 5 C for 20 d and then kept for 7 d at room temperature. A 40% reduction of reproduction was observed in citrus fruit exposed to 0.05% of EO. GC?MS analysis of EOs showed that Ch. ambrosioides EO was composed of 76% monoterpene compounds (49 and 27% of oxygenated and hydrocarbons, respectively), while C. bonaerensis EO presented 17% monoterpenes and
10% sequisterpenes.

Abstract:
Despite increasing calls for the sustainable intensification (SI) of agriculture, environmental impacts associated with historical patterns of yield increase remain poorly understood, particularly involving multiple sustainability indicators. The objective of this study was to examine the sustainability of rice intensification in Uruguay from 1993 to 2013. National rice production and crop management records were used to estimate energy, nitrogen, water, and carbon footprints and agrochemical contamination risk for the rice phase of typical rice-pasture rotations in Uruguay. Results suggest that increases in national production were achieved with simultaneous increases in net energy yield and water use efficiency (56% and 41%, respectively). Although carbon footprint per unit of production decreased (#1;30%),
potential nitrogen losses increased (37%) and elevated agrochemical contamination risk occurred in specific years. This study highlights the potential role of improved agronomy in balancing food production and environmental goals, while also indicating that similar holistic assessments are needed for other rice growing regions to better evaluate SI strategies and quantify potential tradeoffs. |
