| Abstract: | 20% Chitosan-oligo sacchrides was a sed to control 3 kinds of tomato diseases, tomato late blight(Phytophthora infestansde Bary),mosaic virus(CMV and TMV)and gray mold (Botry tis cinerea Pers) in the field.The results showed that control effect of 20% Chito sanligo sacchrides on tomato mosaic virus and late blightwas very obvious, control resultswere 69.30%-81.60% and 66.20-81.76% respectively, its optinum diluting mintiple was 300-500-fold Therefore, 20% Chitosan-oligosacchrides is a effective bio-fungicide controlling the mosaic virus and late blight But its control result to tomato gray mold in the field,only 32%,is not very well. |
