Conyza spp. have become a major weed around the world, mainly because of weed resistance issues. The objective of this work was to test the hypothesis that the soyabean crop yield is dependent on the density of Conyza bonariensis and on the timing of weed estab- lishment in relation to the crop sowing date. It was also theorised that these variables affect soyabean crop yield components and the economic threshold of C. bonariensis on soyabean. Field experiments were conducted during 2010 and 2011 using a randomised complete block design. In each experiment, several densities (0, 3, 6, 12, 24, 48, 96 and 192 plants m-2) of C. bonariensis were established in soyabean fields. Conyza bonariensis establishment dates varied consid- erably between the experiments [81, 38 and 0 days before soyabean sowing (DBSS)]. Conyza bonariensis plants were first cultivated in a glasshouse and then transplanted to the field at the three-leaf growth stage. At the lower densities, each C. bonariensis plant decreased soyabean yield by 36%, 12% and 1.0%, when established at 81, 38 and 0 DBSS respectively. The economic thresholds based on sensitivity analysis were below 0.5 plant m-2 when C. bonariensis was introduced at 81 and 38 DBSS; in contrast, they were between 2 and 4 plants m-2 when the weed was estab- lished at the crop sowing time. The results emphasise the importance of proper C. bonariensis management prior to soyabean sowing and highlight the need for residual herbicides to avoid grain yield losses.

The vitiviniculture at the São Francisco Valley, Brazil, is a recent and under development activity. It is located in the semi-arid of the northeast of Brazil, with socio-economic importance for the region, since the grape chain generates more than 80,000 direct and indirect jobs. The particular soil and climate conditions of the region, associated with the high incidence of radiation, winter absence and availability of water for irrigation, enable the production of grapes and wines of Vitis vinifera L. throughout the year, with two to three harvests per year, depending on the cycle of each variety. |
