STUDY OF GARLIC LEAF BLOTCH (CLADOSPORIUM ALLII) Ⅳ. YIELD LOSS ASSESSMENT AND FUNGICIDE CONTROL EXPERIMENTS

Qin Jiazhong; Yao Wenfang(Sichuan Agricultural University, Yaan, Sichuan, China. 625014)  
In field determining the effect of leaf blotch disease on garlic plant, the criteria for the classification of diseased plants with reference to influences on green-leaf number and withered-yellow area of leaves were defined. The regression equation of the yield to disease index was calculated from the plot experiment (Y%=93.066-0.741x r=-0.933). Fungicide experiments showed that 11 fungicides were effective on inhibiting conidia germination and those of 4 fungicides up to 100% on inhibifting mycelium growth indoor.The control effect of 2 fungicides in the field was significant.
