A new, reliable, and rapid technique to induce sporulation in anastomosis group (AG) 1 and AG2-2 of Thanatephorus cucumeris (=Rhizoctonia solani) is reported. This technique makes use of fungistatic stress by mancozeb to stimulate the production of basidiospores. No environmental conditions (except the incubation temperature of 25 or 30 C) need to be adjusted in this technique.
