The occurrence and control of Peronospora tabacina in Belgium in 1959/1961


, : The occurrence and control of Peronospora tabacina in Belgium in 1959/1961. Parasitica. 18: 8-24. bibl. 13

In Belgium severe attacks of blue mould have reduced yields by 50% in some districts, and as a result the area under tobacco declined in 1961 by 425 ha. or 30%. Observations have shown that the resistance of the plants decreases with age. Maneb and zineb have given good results, but only when the spray coverage has been complete.
