摘　　要：为进一步探究新型植物免疫激活蛋白维大力(0.4%大丽轮枝孢激活蛋白)对促进小麦抗逆、抗病和增产等效果,为我区防治小麦茎基腐病、赤霉病等病虫害发生为害探索绿色防控方法,保障夏粮生产安全。选用3种农药利用种子包衣技术对小麦茎基腐病、赤霉病等开展田间防治药效试验,为防治小麦病虫害药剂选用提供科学依据。结果表明:增产效果明显。0.4%维大力处理产量617.95 kg/667 m^(2),较常规12%苯醚·咯·噻虫处理产量564.99 kg/667 m^(2),产量52.96 kg/667 m^(2),增产率9.4%;较对照产量459.19 kg/667 m^(2),增产158.76 kg/667 m^(2),增产率34.6%。0.4%维大力拌种、5%氨基寡糖素拌种、常规12%苯醚·咯·噻虫拌种,拔节期喷雾后对赤霉病、茎基腐病具有一定防治效果,0.4%维大力对赤霉病、茎基腐病防效较对照差异显著。0.4%维大力处理在小麦生育期各项生物学特性指标表现均较其它三个处理具有优势,增产效果明显。由于小麦苗期、返青期、拔节前期天气干旱少雨,小麦扬花授粉期连续阴雨寡照导致病虫害发生较轻,0.4%维大力是否对茎基腐病、赤霉病、白粉病、条锈病、蚜虫等病虫害具有抑制作用,还需连续多年试验示范研究验证。In order to further explore the effects of a new plant immune-activating protein,VDAL(0.4%Verticillium dahliae activating protein),on promoting stress resistance,disease resistance,and yield increase in wheat,to explore green prevention and control methods for preventing and controlling wheat stem rot,scab,and other pests and diseases in our region,and to ensure the safety of summer grain production,three pesticides were selected,and seed coating technology was used to conduct field control efficacy trials on wheat stem rot,scab,and other diseases,providing a scientific basis for the selection of pesticides for controlling wheat pests and dis-eases.The results showed that the yield increase effect was significant.The yield per 667 m^(2) of 0.4%VDAL treatment was 617.95 kilograms,which increased by 52.96 kilograms compared to the conventional 12%pheni-date chlorpyrifos thiacloprid treatment at 564.99 kilograms per 667 m^(2),with an increase rate of 9.4%.Com-pared with the control,the yield per 667 m^(2) increased by 158.76 kilograms,with an increase rate of 34.6%.The 0.4%VDAL seed dressing,5%aminooligosaccharide seed dressing,and conventional 12%phenyl ether pyrrolidone thiazide seed dressing showed certain control effects on scab and stem base rot after spraying at the jointing stage.The control effects of 0.4%Weidali on scab and stem base rot were significantly more effective than the control.The 0.4%Weili treatment had advantages over the other treatments in terms of various biologi-cal characteristics during the wheat growth period and showed a significant yield increase effect.Due to drought and lack of rain during the wheat seedling,greening,and early jointing stages,along with continuous rain and low light conditions during the wheat flowering and pollination stages,the occurrence of pests and diseases was relatively mild.Whether 0.4%Weili has an inhibitory effect on stem base rot,scab,powdery mildew,stripe rust,aphids,and other pests and diseases still needs to be verified through years of continuous exper
