摘要
研究了拌种威对麦田３种地下害虫（蛴螬、蝼蛄、金针虫）及小麦３种主要病害（纹枯病、白粉病、秆黑粉病）的保苗防病效果。结果表明，用拌种威处理种子后，小麦出苗整齐，叶色浓绿，出苗率比空白对照提高３．０％～５．５％；对麦田３种地下害虫的冬前保苗率和次春防治效果分别比辛硫磷提高４．２％和２６．２％；对３种小麦病害的防治效果与单用三唑酮一致，无显著差异。大面积示范效果与室内、田间试验结果吻合。
The seedling-keeping and disease-prerenting effectiveness of Banzhongwei inpreventing and controlling 3 kinds of underground pests (grubs, mole crickets and wire-worms ) and 3 major wheat diseases ( banded sclerotial blight,powdery mildew and flagsmut ) in wheat fields was studied,The results showed that the wheat seeds treated byBanzhongwei displayed uniformity of seedling emergence and dark-green leaf color. Ger-mination rate can be increased by 3.0%～5.5%compared with CK plots. Field exper-ments showed that the seadling-keeping effectiveness against the 3 kinds of undergroundpests before winter and the disease-preventing effectiveness in the following spring in-creased by 4.2%and 26.2%respectively compared with Phoxim. However, the differencebetween Banzhongwei and Triadimefon was not significant in the effectiveness of preventing and controlling the 3 kinds of wheat diseases. The demonstration results in large areasaccorded with the experimental results. Banzhongwei has shown significant effectiveness inincreasing the output of wheat。
