摘要
通过室内孢子萌发试验和田间喷药防治,研究了植物油乳油对西瓜白粉病的室内活性和田间的防治效果。结果表明:室内试验92%豆油乳油稀释至5.000mL/L和3.333mL/L均能有效抑制白粉病分生孢子萌发;田间防治效果表明,植物油稀释至2.000mL/L与对照药剂20%三唑酮乳油稀释至1.000mL/L在喷药第14天比较,前者效果较好,其防效超过70%。
The spores germination of different amount of vegetable oil Ec on the shape of conidial germ tubes of Sphaerotheca fuliginea Poll and its application to control were studied. The results showed that the effect of 92% 5. 000 mL/L and 3. 333 mL/L inhibiting spores germination was effective. Vegetable oil emulsion proved results that soybean oil Ec diluted to 2. 000 mL/L,the effects of controlling reached over 70% until the 14th day.
