Determining frequencies of fungicide resistance in Leptosphaeria maculans that render demethylation inhibitor fungicides ineffective in the field

Pest Management Science, EarlyView.
As little as 1–10% of the population is needed to be resistant for demethylation inhibitor fungicides to be rendered ineffective. Following a single round of selection, the frequency increases by more than 15% with limited fitness penalty detected when no selection is present.

The epidemiology of the blackleg pathogen, Leptosphaeria maculans, impacts fungicide resistance management strategies

Pest Management Science, EarlyView.
Understanding how infection timing drives disease is essential for the development of fungicide resistance management strategies. For blackleg disease of canola, all infection timings can contribute to the following generation, therefore all fungicide applications have the ability to select for resistance.

Evolutionary trade‐offs between beauvericin production and growth define divergent virulence strategies in Beauveria

Pest Management Science, EarlyView.
Two virulence strategies in Beauveria: a growth strategy characterized by rapid within‐host proliferation, and a toxin strategy involving antimicrobial activity and toxicity to insects Abstract BACKGROUND Pathogen virulence is often attributed to toxin production, yet toxins are metabolically costly and may not universally enhance fitness.

Endophytic fungi from two isolated Bethencourtia palmensis populations: metabolomic and bioactivity fingerprinting

Pest Management Science, EarlyView.
We compared two island populations of Bethencourtia palmensis and their culturable endophytic fungi, revealing distinct plant chemistries and a higher biopesticidal potential in the endophytic fungi from La Palma population along with high potential for the discovery of novel compounds.

Combined application of Bacillus velezensis JDB15 and Trichoderma harzianum JDL4 suppresses banana Fusarium wilt under controlled conditions

Pest Management Science, EarlyView.
The surfactin C secreted by JDB15 and the probable parasitism of JDL4 lead to the leakage of intracellular macromolecules and the degradation of hyphae, respectively. Combined application of the two strains effectively controls banana Fusarium wilt under controlled conditions.
