Abstract:
Dissipation curves of azoxystrobin and of the neonicotinoids acetamiprid and thiacloprid in peach; azinphos-methyl and carbaryl in pear and azoxystrobin, chlorfenapyr and chlorpyrifos in high-tunnel tomato crops were studied in the Southern region of Uruguay. An analytical methodology based on solid phase extraction (SPE) and detection by High Performance Liquid Chromatography with Diode Array Detector (HPLC/DAD) was used for acetamiprid and thiacloprid. Coupled SPE and detection by Gas Chromatography with Mass Selective Detector (GC/MSD) was used for the detection of azinphos-methyl, azoxystrobin, carbaryl, chlorfenapyr and chlorpyrifos residues. Curves were modeled mathematically with Solver program of Microsoft Excel. The best fit for acetamiprid and thiacloprid in peach was achieved with the exponential model (r(2)=0.961 and 0.944, respectively). In the case of peach fruits there is not a Maximum Residue Limit (MRL) for acetamiprid in the Codex Alimentarius, while 0.5 mg/kg is the value rated for thiacloprid. The MRLs accepted by the European Union (EU) are 0.1 mg/kg for acetamiprid and 0.3 mg/kg for thiacloprid. According to the curves determined in these experiments, thiacloprid residues 10 to 12 days after application (daa) were below the MRLs established by both sources. In the case of acetamiprid, 25 daa would be required, according to the exponential mathematical model, to get residues levels below the MRL values established by the EU. For azinphos methyl in pear, the residues detected were mathematically fitted to an exponential model (r(2)=0.999). According to it, residue levels under the MRL established by the EU (0.05 mg/kg) are gotten in our conditions in 20 daa. In plastic tunnel tomato chlorfenapyr residues were not detected from 16 daa, having the dissipation curve an exponential trend. In the same condition, there was not a decay of the azoxystrobin concentration during a 24-day trial, being it around 0.40 ± 0.05 mg/kg. MenosAbstract:

ABSTRACT.- Spot blotch (SB), caused by Bipolaris sorokiniana is becoming an important barley disease in humid, temperate growing regions, including Uruguay. The narrow genetic base of current donors of resistance and recent changes in pathogen virulence have driven the search for novel sources of resistance. In this study, a diverse collection of 39 barley genotypes was evaluated for SB resistance, and genetic relationships, population structure, and haplotype diversity were investigated using 27 simple sequence repeats (SSRs) and eight sequence-tagged sites (STS) markers linked to nine QTL for SB resistance located on chromosomes 1H, 2H, 3H, 4H, and 7H. Fourteen barley genotypes expressed high and moderate SB resistance at seedling and adult plant stages. Distance and model-based cluster analyses revealed that the 14 selected lines clustered in four groups consistent with geographical origin and pedigree relatedness. Reference SB resistant haplotypes were poorly represented. Based on these results, we suggest that these 14 lines are likely candidates to carry novel genes or alleles for SB resistance. Further research may expand the understanding of the genetic architecture of this trait. © 2024 Informa UK Limited, trading as Taylor & Francis Group. |
