Injurious fungi may be largely destroyed by keep- Varieties. i'^S farm and orchard premises clean and free from weeds and rubbish. Burning potato tops, old tomato vines, and similar refuse, will destroy millions of spores of fungi attacking those plants. The same may be said of apples and pears infected with scab of the fruit, which are too often left hanging on the trees or lying on the ground, to propagate their spores the following season. (3.) With diseases like the brown-rot of plums and cherries, much may be done in H rl P" f reducing injury by persistent hand picking of infected fruit, which should be burned. (4.) The most practicable way of preventing the majority of the fungous diseases of plants, is by the use of " fungicides" or fungus killing mixtures. These act either by directly destroying any fungus spores present at the time of application, or by Use of remaining on the surface, in a-condition to destroy, either before germination ° â or during that process, any spores that may alight upon the plant treated. As treatment is preventive, great care must be exercised to have the work done at the proper season, and to be sure that all parts of trees or. plants sprayed are wetted with the fungicide used. Drenching is not necessary, and sometimes results in injuiy to the foliage or fruit. The aim should be to deposit a thin film or coating of the spray upon the entire surface t
