Contenido :  ABSTRACT.- Cover crops constitute an interesting option for cultural weed control. Expansion of herbicide resistant weeds in Uruguay, has been associated with an increase use of pre-emergent herbicides for their control. Crops residues could decrease their effectiveness. The objective of these work was to evaluate the effect of Avena strigosa straw and moment and amount of rain, in Amaranthus spp. control effectiveness by flumioxazin and sulfentrazone. Two experiments were carried out for each herbicide in pots, in a greenhouse. The design was in randomized complete blocks, with five repetitions and factorial arrangement of treatments. In experiments I, factors were: I) amount of A. strigosa straw (0 and 6 t ha-1); and II) amount of rainfall (20 and 80 mm), for each herbicide. In experiments II, factors were: I) amount of A. strigosa straw (0 and 6 t ha-1); II) amount of rainfall (20, 60 mm); and III) Days between application and rainfall occurrence (1, 7 and 14). Weed emergencies were quantified at days 8, 22 and 39 after rainfall (DAR). Results were independently analyzed using a model with gaussian distribution. Sulfentrazone effectiveness in Amaranthus spp. control was not affected by studied factors. In the case of flumioxazin, straw effect was consistently detected. Amounts of 6 t ha-1 of oat straw reduced Amaranthus spp. control effectiveness of the herbicide. © 2022 Informa UK Limited, trading as Taylor & Francis Group

Contenido :  ABSTRACT.- Orange fruit are sensitive to develop chilling injury (CI) during postharvest storage. Symptoms are brown depressed areas in the flavedo that coalesce with time causing severe economic losses. Abscisic acid (ABA) is applied during preharvest in different crops to promote cold tolerance but its effect in citrus fruit remains unknown. The objective of this work was to study the effect of preharvest application of ABA in alleviating CI during cold storage (1.0 ± 0.5°C). ABA at 500 mg.L−1 was applied at three different maturity stages of ?W. Navel?, ?Valencia? and ?Salustiana? oranges. ABA reduced incidence and severity of CI in the three orange cultivars. This positive effect was cultivar-dependent, being more pronounced in ?W. Navel? and ?Valencia? compared to ?Salustiana?. ?Salustiana? presented the highest CI incidence (>80% of the fruit with symptoms after 9 weeks of storage) and ABA applications only delayed its appearance. CI incidence was reduced up to 61% in ?W. Navel? and 74% in ?Valencia? compared to untreated fruit, concomitantly to severity. Evaluation of fruit quality revealed that ABA application does not affect fruit colour firmness or maturity index. Preharvest applications of ABA in oranges alleviate CI during postharvest cold storage without affecting fruit quality. © 2022 Journal of Horticultural Science & Biotechnology.
