Effects of Prothioconazole on FHB Control,Yield and Quality in Different Varieties of Wheat
摘要
Abstract
To investigate the effects of prothioconazole on Fusarium head blight(FHB)control,yield and quality of different wheat varieties,the experiment was carried out by selecting three wheat varieties:high-susceptible variety Huawei 305,medium-susceptible variety Lianmai 186,and medium-resistant variety Lianmai 12.The translational sprinkler irrigation equipment was used for sprinkler irrigation to establish the conditions for the full incidence of FHB.The results showed that prothioconazole application could significantly reduce FHB occurrence,achieving control effect of disease incidence and disease index rate of 38.97%～71.88%and 29.36%～63.60%.Control effect was further improved with the increase of spraying times.Meanwhile,the control effect of prothioconazole on FHB of Huawei 305 was better than that of Lianmai 186 and Lianmai 12.The prothioconazole application treatment increased 1 000-grain weight and grain yield,while also improved processing quality parameters including protein content,wet gluten content,volume weight,sedimentation value,and farinograph characteristics.The effect of spraying twice was the optimal.By Comprehensive analysis of FHB control effect,grain yield and quality,there was a certain promoting effect on different disease-resistant wheat varieties by prothioconazole application.Among them,the promotion effect on the highly susceptible variety Huawei 305 was significantly greater than that of the moderately susceptible variety Lianmai 186 and the moderately resistant variety Lianmai 12.It was necessary to adjust the application scheme of FHB prevention and control according to the resistance of varieties,providing theoretical basis for the green production of wheat.关键词
