It was reported that darkness favors maximum uredospore
germination of legume rust pathogen Uromycesviciae-fabae .
Initially inoculations of spreaders, 3-5 tillers in a row, were carried out by hypo- dermic syringe method using aqueous uredospore
suspen- sion to which 1-2 drops of Tween-20 were added to break the surface tension.

Secretion of extracellular enzyme by Verticillium psalliotae Treschow and Verticillium lecanii (Zimm,) Viegas during growth on uredospore
of the soybean rust fungus (Phakopsora pachyrhizi Syd).
At mid-whorl stage (mid-July), these spreader plants were inoculated with common rust by injecting 3 mL of a uredospore
suspension [5 mg of uredospores
in 400 mL deionized [H.sub.2]O with 5 drops of Tween 20 (polyoxyethylene-sorbitan monolaurate, Sigma Chemical Co., St.
