Research reveals effects of biocontrol agents on disease control and growth in wild potatoes, suggesting implications for integrated pest management.

Biological control agents can affect disease control and plant growth in wild potato relatives, highlighting their role in integrated pest management.
Research confirmed that the pathogen Alternaria solani can infect all studied wild potato relatives, particularly impactful on annual weeds.
Greenhouse experiments indicated that Bacillus amyloliquefaciens showed disease-controlling effects, whereas Pythium oligandrum did not.
The study emphasizes the environmental costs and benefits of biocontrol agents, advocating careful consideration in sustainable potato cultivation.

Lankinen et al. (2025) studied this question.
