Abstract:
Leafy vegetables could accumulate nitrate (NO3?) above limits safe for humans, hence it would be advisable to customarily determine their NO3? concentration. We wanted to develop a quick test to determine NO3? concentration in fresh tissue extracts and estimate the error of using this test to identify samples with NO3? concentrations above the World Health Organization (WHO) threshold. There was a positive linear relationship (P < 0.001) between NO3? concentrations determined by the quick test and by potentiometry in dry tissue extracts. Samples were classified as ?acceptable? or ?excessive? according to their potentiometric NO3? concentration, using a critical level of 75% (p) of the observed NO3? distribution. According to the Cate-Nelson model, the quick test identified as ?acceptable? from 5.6% to 15.4% of samples that were in the ?excessive? category. In spite of this error rate, the quick test use would improve consumers? protection, because no controls on vegetables NO3? concentration are available in Uruguay. |

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 |
