A suitable approach to resource allocation in biosecurity when considering dependent benefits and costs

Methods in Ecology and Evolution, Volume 17, Issue 5, Page 1519-1534, May 2026.
Abstract Optimal allocation of resources to the management of biosecurity risk, threatened species conservation or natural hazards such as bushfires is imperative—because program budgets are usually finite and, therefore, constrained. However, effectively dividing resources among management activities to achieve the greatest benefit remains a ...

Neoscytalidium dimidiatum Associated With Canker Disease in Spondias mombin L. in Brazil

Journal of Phytopathology, Volume 174, Issue 3, May/June 2026.
ABSTRACT In 2023, Cajá trees (Spondias mombin) exhibiting symptoms of canker and resinosis were collected from a commercial plantation in Teresina, Piauí, Brazil. Affected plants displayed small, irregular cankers on the trunks and branches, accompanied by abundant resin exudation, which coalesced into extensive necrotic lesions.

Neonectria Canker Disease of Fir Caused by Neonectria neomacrospora in Austria

Plant Pathology, Volume 75, Issue 3, May–June 2026.
The fir pathogen Neonectria neomacrospora is first reported on 17 Austrian localities, causing dieback and mortality on Abies alba at cool‐moist sites. A growth experiment on agar presented optimum growth at ~20°C. Moreover, an inoculation experiment revealed higher mortality on A. concolor than A. alba, while Picea abies remained unaffected.

Controlling: Ceratocystis canker of stone fruit trees

California Agriculture, 1965
Ceratocystis canker disease in stone fruit orchards can be prevented or controlled by wise use of mechanical harvesting equipment and by canker surgery. A new mercurial wound dressing developed by University of California researchers has been registered by the USDA for use on bark wounds of almond and prune trees.

A New Epidemic of Woolly Adelgid‐Associated Cucurbidothis spp. Is Damaging the Health of Scots Pine in Scotland

Plant Pathology, Volume 75, Issue 3, May–June 2026.
Surveys of Scots pine in western Scotland revealed the ubiquity of two woolly adelgid‐associated Cucurbidothis spp. and their association with cankers caused by Crumenulopsis sororia. Presence of Cucurbidothis spp. and cankers was linked to crown dieback, confirming the detrimental effects of this Cucurbidothis outbreak on the health of Scots pine ...

Neofusicoccum and Phytophthora Species: An Emerging Threat to Fig Trees (Ficus carica) in Italy, With the Description of Phytophthora messapica sp. nov.

Plant Pathology, Volume 75, Issue 3, May–June 2026.
The work helped clarify the complex aetiology of common fig decline in Italy as the result of a simultaneous attack by canopy pathogens (Ascomycetes, family Botryosphaeriaceae) and root pathogens (oomycetes of the genus Phytophthora) and led to the discovery of several new host–pathogen associations and a new Phytophthora species.

Cassava Endophytic Bacteriome as Potential Biocontrol Agents Against Three Crop Phytopathogenic Fungi

MicrobiologyOpen, Volume 15, Issue 2, April 2026.
Eighty‐four endophytic bacteria from cassava were assessed for antagonistic activity against phytopathogens Colletotrichum siamense, Colletotrichum sublineola and Phytophthora infestans infecting cassava, sorghum and potato, respectively. Fourteen endophytic bacteria exhibited antifungal activity against the three phytopathogens, of which four ...
