Collagen amendments to soil drastically reduced galling of tomato roots by Meloidogyne
javanica when compared with other protein and chitin amendments. The approximate
amount of ammonia released in the decomposition of collagen was inadequately lethal to M.
javanica larvae. On the other hand proteolytic activity lasting at least 21 days in collagen-
amended soil showed harmful effects in vitro on larvae and eggs. Soils amended with
collagen two weeks prior to planting and inoculation showed a 50% reduction in galling of …
