Method of uredospore dispersal of the coffee leaf-rust fungus, Hemileia vastatrix :
Experimental evidence is presented against the view that uredospores of the rust, Hemileia vastatrix, are normally distributed by wind, although this method of dispersal does apparently occur at a very low level. The uredospores of the rust adhere strongly to each other, to leaves, and to any surfaces however smooth. Their mutual adhesion is broken down by water, and it is concluded that the periodic build-up of rust epidemics is almost entirely a result of spore-dispersal by water-splash. This observation has an important bearing on the problem of control
