Comparison of the application effects of two kinds of immune inducers and conventional agents in wheat
In order to verify the effects of immune inducers on wheat growth,disease prevention,yield increase and quality improvement,the effects of VDAL,amino-oligosaccharides,conventional chemicals and blank control on wheat seedling quality,sheath blight control effect,gibberella control effect,yield and vomitoxin were studied by comparing the effects of vitamin oligosaccharides,conventional chemicals and blank control on wheat seed dressing and foliar spraying.The results showed that wheat seed dressing treatment with VDAL could significantly increase the root length of wheat and promote the production of secondary roots,the control effect of spraying immune inducers on sheath blight at the jointing stage of wheat was 83.33%,which was significantly better than that of conventional pesticides,and the control effect of spraying immune inducers on scab at the heading and flowering stage of wheat was 96.45%-98.05%,significantly reduced the production of deoxynivalenol.The use of immune inducers in combination with conventional pesticides at jointing stage and flowering stage could significantly increase the number of grains in wheat,and the yield was increased by 12.1%-13.7%compared with conventional agents alone.Immune inducers have high value in wheat applications.
