THE EFFECTS OF METHYL BROMIDE FUMIGATION AND FARM MANURE APPLICATION ON SEVERITY OF CORYNEBACTERIUM MICHIGANENSE ON GREENHOUSE TOMATOES |

| Abstract:
In a greenhouse experiment, the combined effect of soil fumigation with methyl bromide and stable manure application on the incidence of Corynebacterium michiganense during two successive tomato cropping was investigated. In the first tomato cropping after soil fumigation, the best bacterial canker control gave methyl bromide at a dosage of 80 g/m2, especially on the plots where manure was applied before fumigation. The highest methyl bromide rate /110 g/m2/, if not combined with manuring, significantly stimulated the disease. The opposite effect was observed in the second tomato cropping after soil fumigation. Methyl bromide used at dosages of 50 and 80 g/m2, in most cases, significantly increased the number of infested plants, but applied at 110 g/m2 markedly suppressed the disease. Manuring itself stimulated the occurrence of C. michiganense. | |
