Hao JJ et al. (2012) studied antimicrobial activity of chestnut extracts for potential use in managing plant pathogens.

Chestnut extracts were studied for antimicrobial activity against selected microorganisms, including plant pathogens. Most test microorganisms were inhibited by the extracts at different effective concentrations for 50% growth inhibition (EC50). Pseudomonas fluorescens was the most sensitive, Phytophthora cambivora was one of the least inhibited, and Cryphonectria parasitica was not inhibited.

Extracts of the Japanese × European chestnut (Castanea crenata × C. sativa) ‘Colossal’ showed a greater inhibition than those of wild trees of the Chinese species (C. mollissima).

Pellicle and shell tissue reduced radish scab disease caused by Streptomyces scabies in the greenhouse.
