- Abstract
【Objective】 The purpose of this research is to clarify the field dynamics of wheat powdery mildew in newly breed varieties in the hope of providing theoretical basis for scientific prevention and control of the disease.【Method】The occurrence of powdery mildew in different wheat varieties was systematically investigated by means of regular fixed-point investigation.【Result】The results showed that the field dynamics of wheat powdery mildew of Xindong No.60, Xindong No.57 and Xindong No.40 were basically the same. The highest disease index of wheat powdery mildew of Xindong No.60, Xindong No.57, Xindong No.40 and Xindong No.20 were 8.22, 7.11, 37.63 and 25.48, respectively. Repeated measurements showed that the occurrence degrees of wheat powdery mildew in Xindong No.60 and Xindong No.57 were significantly lower those in Xindong No.40 and Xindong No.20, and that in Xindong No.40 was significantly higher than that in Xindong No.20.【Conclusion】The occurrence degrees of wheat powdery mildew in Xxindong No.60 and Xindong No.57 were significantly lower than that in Xindong No.20 and the pesticide application could be reduced reasonably according to the occurrence of wheat powdery mildew in the field; The occurrence degree of wheat powdery mildew in Xindong No.40 was significantly higher than that in Xindong No.20, so the prevention of wheat powdery mildew should be strengthened. In this study, the field dynamics of wheat powdery mildew in Xindong No.60, Xindong No.57, Xindong No.40 and Xindong No.20 were clarified, which might provide theoretical basis for the relevant scientific prevention and control of the disease.
