“…Desiccation of soybean seeds using ammonium glufosinate, paraquat, and carfentrazone applied at the R7.1 stage showed no reduction in germination (Pereira et al, 2015). Lima et al (2018) used ammonium glufosinate and diquat to desiccate cowpea plants found no differences in germination and vigor right after harvest when desiccation was carried out between 50 and 100% of brown-colored pods.…”

The use of desiccants allows to anticipate cowpea harvest at a time closer to physiological maturity. The desiccants saflufenacil and flumioxazin promote the drying and falling of leaves and loss of water from seeds. This study aimed to evaluate the effects of saflufenacil and flumioxazin doses applied to the cowpea crop on the production and quality of seeds at harvest and after storage for six months. Two experiments were carried out in a split-plot design (5 × 2). In the first experiment, the main factor consisted of saflufenacil doses (0, 25, 50, 100, and 150 g ai ha-1), while the second factor consisted of evaluation periods (after harvest and six months after harvest). In the second experiment, the main factor consisted of flumioxazin doses (0, 10, 20, 30, and 40 g ai ha-1) and the second factor consisted of the same evaluation periods. The treatments were designed in randomized blocks, with four replications. Saflufenacil application from 25 g ha-1 compromised the yield components and technological quality, while flumioxazin doses did not affect the yield components. Storage at 20 °C for six months decreased the physiological quality of seeds. Flumioxazin application at cowpea harvest promoted uniformity of maturity and harvest anticipation, without compromising the physiological quality after harvest.

“…Seeds coming from the treatment with glufosinate ammonium had a percentage of normal seedlings after accelerated aging lower than the percentages from the other treatments. According to Lima et al (2018), seeds from common bean desiccated with glufosinate ammonium at different time periods have lower NSAA values in relation to the untreated control. Tavares et al (2016) also observed effects after storage of seeds coming from a treatment with application of paraquat for desiccation of azuki bean.…”

“…High quality seeds depend on harvest occurring at the ideal time, frequently when physiological maturity is reached, coinciding with maximum accumulation of seed dry matter, high vigor, and high germination (Lima et al, 2018). One of the alternatives is desiccant herbicide prior to harvest, which can reduce exposure of seeds to unfavorable environmental conditions.…”

Abstract: The aim of this study was to evaluate the effects of pre-harvest desiccant herbicides on the yield and the physiological and technological quality of cowpea seeds after harvest and after storage. The experiment was conducted in a randomized block design with four replications. A split-plot design (6 × 2) was composed of the desiccant herbicides flumioxazin (30 g ai.ha-1), glufosinate ammonium (500 g ai.ha-1), paraquat (400 g ai.ha-1), saflufenacil (70 g ai.ha-1), and carfentrazone (24 g ai.ha-1) and an untreated control, as well as two seed evaluation periods, at harvest and six months after h arvest. Desiccants were applied at the R5 stage. The desiccants affected the yield, classification, color, and physiological quality of seeds of ‘BRS Guariba’. The glufosinate ammonium and paraquat herbicides compromised seed physiological quality. Flumioxazin did not affect seed yield components, color, and physiological quality. Storage at 20 °C for six months affected seed physiological quality.

“…Se han desarrollado varios estudios que abordan el tema del uso de herbicidas como desecantes para diversos cultivos, como soja (Glycine max) (Marchi et al, 2021), frijol común (Phaseolus vulgaris) (Lima et al, 2018), sorgo (Sorghum bicolor) (Barros et al, 2019) y trigo (Triticum) (Souza et al, 2020). Sin embargo, para el cultivo de frijol existen pocos trabajos que puedan orientar a los agricultores en la elección del desecante adecuado, especialmente en la región norte de Brasil.…”
