TO FIGHT DISEASE.
Aircraft To Counter Rust Losses In Wheat.. CANADIAN SERVICE. (British Official Wireless.) RUGBY, September 29. The use of aeroplanes in fighting plant diseases was described at a meeting of the Imperial Mycological Conference in London on Thursday. Dr. Gussow, a Canadian delegate, said that enormous losses were caused in the wheat belt by rust which took an average toll of £5,000,000 a year. In 1916, when there was a bad epidemic, the cost to the Dominion was £50,000,000. Aeroplanes were used in trapping spores of fungus on gelatine slides. Mycologists had found that spores of rust were coming from the south on air currents and their progress could be traced throughout the season. The speaker said he had trapped fungus spore at an altitude of 10,000 ft.
