【摘要】 9ppm涕灭威对生长在灰葡萄孢霉上的松材线虫有很强的抑制繁殖作用。每株黑松注入15%涕灭威颗粒剂40g,30天后树干内的涕灭威含量为20.013～51.796ppm;50天内为17.575～40.386ppm。含不同剂量涕灭威的木屑对松材线虫的繁殖有不同程度的抑制作用。在松褐天牛羽化期,黑松树干注射一次涕灭威,当年保株率达100%。更多还原

【Abstract】 Temik 9ppm can successfully control the reproduction of Bursaphelenchus xylophilus growing on the Botrytis cinerea. If 40 grams of 15% temik granule are injected into each Pinus thunbergii Parl, the contents of temik in the trunks will be 20.013~51.796 ppm in 30 days and 17.575-40.386 ppm in 50 days. Sawdusts mixed with different contents of temik will influences the growth of Bursaphelenchus xylophilus at different extent. During the emergence of Monochamus alternatus Hope, 100 % of the boles of Pinus thunbergii are protected by injecting temik into the trunks only once a year. A new way is provided to control Bursaphelenchus xylophilus.更多还原
