| Abstract: | Investigation on developmental pattern of sooty mould in wheat and barley carried outfrom 1988 to 1989 in Taian city indicated that the sooty mould was closely related with thenumber of aphids and relative humidity in fields.When aphids per 100 plants were less than2000,the dicease indices were positively correlated with varying number of aphids.Twocurves were discrete when numbers of aphids per 100 plants were more than 6000.High rela-tive humidity increased sooty mould.The weight per 1000 grains of wheat decreased by19.57% when the disease index was above 75.Screening fungicides showed thatcarbendazim and thiophanatemethyl were effective against the main pathogens of sootymould.The integrated control of sooty mould in wheat and barley is also discussed. |
