Spodoptera frugiperda (J.E. Smith) is a serious lepidopterous pest of several economically important crops. Control of the fall armyworm has depended exclusively on insecticides. As a result, this pest has developed resistance to major classes of insecticides. There has been mounting interest in the use of synergist to reduce this resistance by combined application of insecticide with synergists. A highly effective, expensive insecticide might be used at a diluted rate with a less expensive chemical to give satisfactory control of a target insect and minimize the contamination of agro ecosystem. |

Abstract Context: Defoliation management targets applied to forages under the full sun have not yet been properly evaluated for shaded environments such as occur in integrated crop?livestock systems with the presence of trees. Aims: This study aimed to determine defoliation targets under full sun and shaded environments for the shade-tolerant perennial summer grass hybrid Axonopus catharinensis (giant missionary grass), widely used in pasture systems of South Brazil and Argentina. Methods: Four pre-defoliation canopy heights (15, 25, 35 and 45 cm) and four defoliation severities (20%, 40%, 60% and 80% reduction in pre-defoliation canopy height) were evaluated. Plants were grown in 0.15 m3 wooden boxes filled with sand/vermiculite substrate (1:1 v/v) and irrigated with a complete nutrient solution. An artificial shade structure was made with wooden slats, reducing light intensity by 50% for shaded plants. Key results: Herbage accumulation decreased by 54% in shaded plants compared with those under full sun. Regardless of the light environment, the lowest crude protein content (<150 g/kg dry matter) and the highest neutral detergent fibre content (>650 g/kg dry matter) were observed when the defoliation target height was >35 cm. Both shaded and full sun environments showed decreases in tiller density when defoliation severity was >60% of pre-defoliation canopy heights. Conclusions: Pre-defoliation canopy heights >35 cm and defoliation severity >60% of pre-defoliation canopy height should be avoided when managing A. catharinensis, regardless of the light environment. Implications: Recommended targets may be easily implemented by livestock producers and are similar for full sun and shade environments. Keywords: Axonopus catharinensis Valls, canopy height, defoliation severity, defoliation target, herbage accumulation, integrated crop-livestock systems, tiller density.
