The nematocides used in this experiment were emulsifiable 1,2-dibromo-3-chloropane(DBCP), emulsifiabledichloro-diisopropyl ether (DCIP), and granular dichloro-diisopropyl erher (DCIP). Growth of Sunki, Citrus reticulata var. Sunki.was verysignificantly decreased by infestation of the citrus nematode. Tylenchulussemipenetrans, and increased by application of nematocides. Efficacyof the DBCP for controlling the citrus nematode was significantlymuch better than that of the DCIP, and the emulsifiable DCIP was significantly better than the granular DCIP as the equal applied rat eof active ingredient concerned. The emulsifiable DBCP applied at the rate of 6 grams of active ingredient per square meter would be very practicable and effective for controlling the citrus nematode in the field condition. 本試驗所使用之殺線蟲劑,計有DBCP乳劑 DCIP 乳劑 及DCIP 粒劑三種。供試之苗水為酸橘。經一年之田間試驗結果,得知酸橘之生長受柑橘線蟲為害至為顯著。凡經上述三種殺蟲劑處理者,除DCIP 粒劑每平方公尺施用三公分之有效藥量處理外,對酸橘之生長均有顯著之增進。尤以DBCP乳劑每平方公尺施用九公分及六公分有效藥量時效果最佳。較對照區使酸橘之株高平均增長約2.1倍,並使株重平均增重平均增長約3 . 6倍。同時可完全消滅線蟲。一般言之,上述三種殺線蟲劑。以DBCP乳劑之效果為最佳,次為DCIP乳劑,效果最差者則為DCIP粒劑。此外,根據此一試驗結果,得知酸橘生長之優劣與柑橘線蟲在土壤中存在量之多寡有顯著之關連;柑橘線蟲殺死量與殺線蟲劑之施用量多寡亦各有顯著之關連。 |
