The effect of 10 fungicides on survival of A. tumefaciens in various types of soils was studied. In fertile, nonsterile soil Dithane M-45 (mancozeb), Euparen 50 WP (tolyfluanid), Kaptan 50 WP (captan) and Ridomil Gold 80 WP (metalaxyl) at concentration of 1000 ppm showed the highest antibacterial activity. Similar trends in activity of these fungicides occurred in fertile, sterile soil, however a little lower in case of Kaptan and Euparen. In most of investigated soils Befran 25 SL (imimnoctadyne), Syllit 65 WP (dodine) and Thiram Granulfo 80 WG (thiram) increased bacteria number. In sandy acidic soil (pH 3.5) all tested fungicides totally eliminated bacteria. On the other hand in sandy neutral soil only Dithane, Euparen, Kaptan and Ridomil showed such activity. Ten fold decrease of fungicides concentration generally did not influence Kaptan and Ridomil effectiveness but it decreased the activity of Dithane and Euparen.

The susceptibility of 29 cultivars of chrysanthemum, representing various types of growth, to crown gall was studied. Two isolates of Agrobacterium tumefaciens: chrysanthemum and apple were used for testing plants. The inoculation was made to the stem base of rooted cuttings and places of pinching off. The first method gave larger galls on most tested plants and only three cultivars were resistant to inoculation with both A. tumefaciens isolates. Weak symptoms were obtained after cutting of stem tips, thus plants of 9 and 5 cultivars (in subsequent tests) showed no symptoms. Only three chrysanthemum cultivars were resistant to crown gall in all tests: Epidote Jaune, Epidote Orange and Epidote Rouge, all belonging to potted chrysanthemum. Plants of Maracas cultivar were resistant when bacteria were applied to the wound of stem tips. In all tests, the apple isolate was weak pathogenic, thus no gall were observed on many cultivars.
