The kernels are filled with arather dull, brownish powder, which has a very disagreeable and penetrating odor. The disease is spread by the use of smutted seedand is to be prevented by sowing on clean groundand with seed free from smut spores. The infected seed may be practically if not entirelyfreed from the disease. The methods used consist insoaking the seed in certain solutions, or simply in hotwater. The most common solutions are a saturatedsolution of common salt and a five per cent solutionof copper sulphate. The wheat should be placed insacks or baskets and these put into the solution andallowed to stand twenty-four to thirty-six hours, whenthe wheat should be spread out to dry.
