Abstract
The effects of butyric acid were evaluated on fungal and nematode endo-parasites of strawberries under controlled laboratory conditions.
Verticillium dahliae, Rhizoctonia fragariae, R. solani, Phytophthora fragariae, and a Pythium sp. were killed after a 2-d incubation in butryic
acid-treated sand (0.88 and 8.8 mg gK1
). No fungal growth occurred in the presence of vapors from 0.1 and 1 M butyric acid solutions. Gall
formation on tomato roots by Meloidogyne hapla, and M. incognita was reduced by 73≠100% relative to controls when egg masses were
incubated in butyric acid solution (0.1, 1 M) or treated sand (0.88 and 8.8 mg gK1
