[Objective] The paper was to culture the plasmodia of Physarum pusillum for obtaining the optimal condition of sporophores and sclerotium, to reduce the agricultural diseases. [Method] Liquid culture combined with oat-agar culture was used to culture plasmodia of P. pusillum. Then plasmodium was induced to obtain Sporophores in lab by hunger and adjusting light (3 000, 6 000, 9 000, 12 000 lx) and temperature (20, 22, 24, 26 掳C). [Result] Sporophores and sclerotium of P. pusillum were obtained from both oat-agar media and liquid media. The optimal conditions were 26 掳C, 6 000 lx and 22 掳C, 3 000 lx. [Conclusion] The result provided theoretical basis for reducing the loss of crops caused by myxomycete as much as possible in agricultural production.
