落枯净和粉锈宁杀菌油剂研制及其应用技术的研究

STUDIES ON PREPARATION AND APPLICATION TECHNIQUE OF OIL SOLUTIONS OF MIXTURE FUNGICIDE LUOKUJING AND FUNGICIDE TRIADIMEFON

从1981～1985年,研制出落枯净和粉锈宁两种高效低毒杀菌油剂,并对其应用技术进行了研究。落枯净油剂使用飞机超低量喷雾联合防治落叶松枯捎病、落叶病的平均防治效果为70％左右,与百菌清油剂相近,但防治成本降低15.7%,并药源充足。粉锈宁油剂超低量喷雾防治落叶松褐锈病,杨、柳叶锈病的效果在80％以上,用2.5％或5％粉锈宁油剂使用飞机防治褐锈病,比施用硫磺烟刑成本降低26.4％或3.6％提高工效13.2倍。

This paper discribes the preparation and technique of oil solutions of mixture fungicide Luokujing and fungicide triadimefon.The results of the experiment showed that Luokujing oil sulution had 70％ average control effect on latch shoot blight (Botryosphaeria laticina (Sawada) Shang) and larch leaf-cast (Mycosphaerella laricileptoleps Ito et al.) in ultra low volume aerial spray. Comparing with chlorothalonil oil solution, the former had very close control effect. The control cost reduced by 15.7% and it was available in-large mounts.Triadimefon oil solution had control effect of over 80% on larch brown rust [Triphragmiopsis laricinum (Chou)Tai], willow leaf rust (Melampsora laricipopulina Kleb and Melampsora salicina Lev) in ultra low volume aerial spray.The costs of using 2.5% and 5.0% triadimefon oil solution for larch browm rust [Triphragmiopsis laricinum (Chou) Tai] in ultra low volume aerial spray reduced by 3.6% and 26.34% respectively compared with that of using sulfur smoke generator, and the work efficiency increased by 13.2 times.
