Field resistance of orange fruit to citrus black spot and citrus canker in D‐limonene synthase downregulated trees

open access: yesPest Management Science, EarlyView.
Genetically modified (GM) sweet‐oranges with downregulated CitMTSE1 gene showed reduced citrus black spot severity and citrus canker incidence, confirming terpene modulation as a promising strategy for sustainable field citrus disease resistance. Abstract BACKGROUND Citrus black spot (CBS), caused by Phyllosticta citricarpa, and citrus canker (CC ...

Characteristics of fungicide resistance in Asian soybean rust (Phakopsora pachyrhizi) in Paraguay for 2022–2023: insights from genetic mutations and molecular dynamics simulations

open access: yesPest Management Science, EarlyView.
Phakopsora pachyrhizi in Paraguay showed diverse resistance to DMI, SDHI, and QoI fungicides at both regional and intra‐field levels, likely driven by target mutation genes. Abstract BACKGROUND Phakopsora pachyrhizi, the causative agent of Asian soybean rust, poses a major threat to soybean production in South America. The rising incidence of fungicide

A new method to measure EC50 reveals cultivar‐specific fungicide resistance and very high diversity within experimental field populations of Zymoseptoria tritici

open access: yesPest Management Science, EarlyView.
We isolated Zymoseptoria tritici strains from a diverse wheat field and quantified fungicide resistance using a novel plate assay. We found high diversity in fungicide sensitivity and host–fungicide–pathogen interactions. Abstract BACKGROUND Zymoseptoria tritici causes Septoria tritici blotch (STB), the most damaging wheat disease in Europe. In Europe,

Sensitivity to demethylation‐inhibiting fungicides and induced expression of CYP51 associated with tebuconazole resistance in Alternaria species on mandarin in Brazil

open access: yesPest Management Science, EarlyView.
Tebuconazole‐resistant isolates overexpress CYP51 and, when tested at field rates, did not reduce ABS severity, whereas difenoconazole and mefentrifluconazole remained effective. Abstract BACKGROUND Alternaria brown spot (ABS), caused by Alternaria spp., is an important disease affecting mandarin production in several citrus‐growing regions worldwide ...

Field investigation of glucosinolates and morphological traits in mitigating Psylliodes chrysocephala larval infestation through crop varieties and companion planting

open access: yesPest Management Science, EarlyView.
Genotype and cropping system influenced oilseed rape ecophysiological traits, including glucosinolate compounds (glucoraphanin, glucobrassicanapin, and butyl‐glucosinolates) and biomass, which were linked to Psylliodes chrysocephala larval infestation, with varietal effects stronger than faba bean companion planting.
