Abstract: Crop cycles in spring canola (Brassica napus L.) and carinata (Brassica carinata A. Braun) are controlled by temperature and photoperiod. In the central region of South America, which accounts for 90% of South American rapeseed crop production, farmers seek to sow as early as possible to maximize yield even though early sowing dates expose crops to a higher probability of frost occurrence that had not been quantified before. Our objective was to model phenology for one spring cultivar of canola (?Rivette?) and one of carinata (?Avanza 641?) and assess the probability of frost occurrence during flowering and grain filling in the central region of South America. For the estimation of frost risk, we modeled phenology resulting from 15 April to 15 August sowing dates at 12 locations (from 31.16˚ to 34.20˚ S latitude). We assumed that the critical period spans from 100 to 500 growing degree days (GDD) after flowering. Under early sowing dates, carinata tends to have a longer cycle (200 GDD more than canola) although both crops had a similar cycle lengthunder a late sowing date. Predicted and observed flowering dates showed an average difference of 1.6 and 0.95 d for canola and carinata, respectively. Carinata has a lower probability of suffering frost events, and early sowing dates result in a greater exposure to frost damage. The results of this work will enable farmers and stakeholders to know the potential frost risk when defining a sowing date for canola and carinata. © 2022 The Authors.

ABSTRACT.- Pecan scab caused by Venturia effusa is the main crop disease affecting leaves and fruits, resulting in defoliation and yield and fruit quality losses. Recently, pecan groves expanded into Uruguay, Brazil and Argentina, where the temperate-humid climate is conducive for scab development. Chemical control is difficult given the height of adult trees which exceeds 20 m. Therefore, the strategy consists on selecting tolerant cultivars accompanied by cultural management aimed at providing a good ventilation and light interception. The objective of this work was to assess the susceptibility of pecan cultivars to Venturia effusa in the Uruguayan agroclimatic conditions. Disease severity index (DSI) in fruits and leaves were determined in 18 cultivars throughout four consecutive seasons. Most of the cultivars evaluated were classified as resistant with fruit disease severity index (DSIF) below 2.0, being Elliott and Sumner the most resistant ones (DSIF < 1.5) while Mahan was susceptible (DSIF > 3.0) and Apache and Wichita were very susceptible (DSIF > 4.5). © 2022 Informa UK Limited, trading as Taylor & Francis Group |
