. Fig. 9.—Scab on wheat. The four heads in the middle show various degrees of infection, and the head at the right, diseased throughout, shows clusters of the spore-bearing bodies of the scab fungus. The head at the left is not infected. The nine kernels at the extreme left are normal; those to the right of them show varying degrees of scab injury. Such injury lowers the market value of wheat. Even slightly injured grain, when used as seed, produces poor stands.
