“…Early harvesting by desiccation reduces the possibility of damage caused by pests and fungi, promotes uniformity of maturation, enables control of adult weeds, reduces impurities and improves crop efficiency, besides making the area available for other crops (Inoue et al, 2003;Griffin et al, 2010). However, it is important to know the product's mode of action, application phenological stage, the behavior of cultivars and their growth habit (Zagonel, 2011).…”

Depending on the cultivar, the use of desiccants in the preharvest can favor maintenance of physiological quality. The objective of the study was to assess the physiological quality of soybean seeds as due to the use of apreharvest desiccant and desiccation time in two harvests (2011/12 and 2012/13). The treatments were five soybean cultivars, two growth stages of application, a control (without desiccant application), and three desiccants (glufosinate-ammonium, carfentrazone-ethyl and paraquat) (2011/12 harvest). In the 2012/13 harvest the carfentrazone-ethyl desiccant was replaced by diquat. The physiological quality of seeds was assessed by the percentage of viability and vigor (cold test, tetrazolium test and accelerated aging test). In 2011/12 harvest, there was an early harvest in six days with the use of glufosinate-ammonium and paraquat desiccants, when desiccation was done in stage R7.1, with maintenance of seed quality; however it was dependent on the cultivar. In the 2012/13 harvest there was no early harvesting due to the presence of rain in the preharvest and the use of desiccation did not affect the physiological quality of the seeds either. Cultivar NA5909 RG was more tolerant to remaining in the cultivation environment and maintained higher viability than 90% and greater vigor of 71% by the cold test compared to cultivar BMX Turbo (2011/12 harvest). It is concluded that desiccation can be a viable alternative to the soybean early harvesting, but it depends on the cultivar, the time of desiccation, the active principle of the desiccant and the absence of rain in preharvest.

Preharvest Herbicide Treatments Affect Black Bean Desiccation, Yield, and Canned Bean Color

et al. 2016

To facilitate direct harvest, preharvest herbicide applications are used to desiccate weeds and to accelerate and promote uniform dry bean (Phaseolus vulgaris L.) maturation. Field trials were conducted near Richville, MI, in 2013 and 2014 to evaluate the effects of preharvest herbicide treatments on desiccation, yield, and canned black bean quality and color. Three black bean cultivars, Zorro, Eclipse, and Zenith, were planted on two different dates in each of 2 yr. Three preharvest herbicide treatments, paraquat, glyphosate, and saflufenacil, were applied at a standard (pods = 80% yellow) and an early (pods = 50% yellow) application timing. A nontreated control was established for each cultivar. Differences in black bean desiccation were greatest 3 d after treatment (DAT), with paraquat and saflufenacil showing the quickest desiccation at the early application timing. By 7 DAT, desiccation for most preharvest treatments was >95%. Saflufenacil applied at the early timing reduced yield by as much as 55% compared with the nontreated control. Yield was generally not affected when preharvest herbicide treatments were applied at the standard application timing. Black bean cultivar influenced canned bean color retention (Zenith > Zorro > Eclipse). Preharvest herbicide treatments reduced color retention when applied at the early application timing; glyphosate reduced color retention by as much as 24%. Because of variability in bean maturation rate within a field, preharvest herbicide treatments need to be applied as close to physiological maturity as possible to minimize yield losses and maintain color retention of canned black bean.

Pre-harvest desiccation in order to minimize the time of exposure to abiotic factors after physiological maturity is a practice used in the production of quality seeds. The aim of this work was to evaluate the physical, physiological and sanitary quality of wheat seeds from plants that received non-selective herbicide application at pre-harvest. For this, the treatments were applied on pre-harvest culture. A completely randomized design was applied. We use the herbicides (glufosinate-ammonium, glyphosate and paraquat), phenological stages of herbicide application (Z-83, Z-85, Z-87, Z-92) and additional treatment (without application). The routine tests that express the physical, physiological and sanitary integrity of seeds were evaluated. For herbicide treatments, there was an 8% and 26% reduction in germination under laboratory conditions for BRS Parrudo and Sinuelo, respectively. Soil emergence was 14% higher for the control treatment, not statistically different for the Z-87 and Z-92 stages and also for the herbicides glufosinate-ammonium and glyphosate for both cultivars. The application of non-selective herbicides on wheat pre-harvest impairs the physical and physiological quality and promotes faster deterioration. Vigor is reduced under stress conditions by cold test and accelerated aging. There is no influence on seed sanity.
