PLANT-REARING AGENT, PLANT DISEASE RESISTANCE INDUCER, AND PLANT DISEASE CONTROL METHOD

摘要

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. Thus, new types of agricultural crop businesses such as contract cultivations by means of organic cultivation, agricultural chemical-free cultivation and hydroponic cultivation are promoted.
