The amount of debris mixed with seed is,on the other hand, not very large, which again cuts down the probability for successful transmissions. Role of Infected Seeds in Disease Initiation Five microplots with 19 infected seeds each were prepared inside a macroplot of susceptible chickpeas.

By March 26, 100% infection was reached. The X
