SUPPOSED REMEDY FOR RUST.
The Government Agricultural Chemist (Mr A, N. Pearson) was recently requested (says the Argus) to report on the use of carbolic acid as remedy a for rust in wheat. Mr Pearson states from what is known concerning, the nature of the rust fungus (puccinia graminis), that it is doubtful if any treatment of the wheat seed would prevent the developement of rust. As regards the effect of carbolic acid on smut, it has been tried by the principal of the Agricultural College, New Zealand, but it was a signal failure. Four ounces of carbolic acid to two gallons of water were used, and the crops grown from the wheat treated with the mixture were in each case more smutty than those grown from non-pickled seed. In the college report for 1884 it is stated that, with respect to the experiments with carbolic acid, it was used on several acres of wheat in three fields. In every case the produce of the wheat so dressed was smutted, the remainder of the field being free. The results of the laboratory experiments go to show that carbolic acid will kill the seed wheat before it affects the vitality of tbe adhering smut spores.
