Abstract: A disease resistance capacity of vegetables, grasses and flowers, etc., is enhanced and their survival rates are improved by growing plants in an appropriate coexistence of a glycolipid derived from Pantoea agglomerans or a composition containing the glycolipid. Thereby, a method of augmenting disease resistance of vegetables, grasses and flowers, etc., and growing agricultural crops with high quality is provided, and further a novel plant growing agent and plant disease resistance inducer that enables this are provided. As a result, it becomes possible to cultivate agricultural crops or increase productivity with as little use of agricultural chemicals as possible. Even if an amount of the agricultural chemical is reduced, a cultivation success rate of agricultural crops can be enhanced and immunity of the plant body can be enhanced even where useful soil bacteria are not frequently present.
