松梢螟(Dioryctria splendidella H.S.),豹蠹蛾(Zeuzera sp.)、松干蚧(Matsucoccus matsumurae)一旦在林木上营隐蔽性生活后,采用常规喷雾喷粉的防治方法,即难以奏效。打孔灌注内吸农药的方法,虽有较好防效,但有损材质,防碍观瞻。呋喃丹作为一内吸性药剂,施用于土壤后,有效成份被根部吸收,在水分充足的情况下,即输导至植物的各个部分,因而可用来防治茎叶部分的咀嚼和吮吸害虫。根据此药在土壤中残留药效持久的特性,我们进行了试图阻止松梢螟、豹蠹蛾的为害和防治松干蚧的试验。 材料和方法 供试农药3％呋喃丹颗粒剂为美国FMC(食品机械公司)化工厂出产,活性成份为3％,化学名称为0—2,3—二氢—2,2—二甲基—7—苯并呋喃基7—N—甲基氨基甲酸脂。 阻止松梢螟为害试验的林分为6年生 Dioryctria splendidella H.S., Zeuzera sp., And Matsucoccus matsumurae are ineffective with conventional spray dusting methods once they have been hidden in the forest. Punch perforation of pesticides within the absorption method, although better anti-efficiency, but the loss of material, hinder the view. Carfuran as an internal absorption of drugs, applied to the soil, the active ingredient is absorbed by the roots, in the case of adequate water, that is, to the various parts of the plant, which can be used to prevent stems and leaves chewing and sucking pests. According to the drug’s long-lasting residual efficacy in soil, we tried to stop the pine stem borer, codling moth damage and control of pine dry scale test. Materials and Methods Test pesticides 3% carbofuran granules for the United States FMC (Food Machinery Company) chemical plant production, the active ingredient is 3%, the chemical name is 0-2,3-dihydro-2,2-dimethyl- Benzofuranyl 7-N-methylcarbamate. Pine wood borer damage prevention test of the forest is 6 years
