苯甲酸盐水剂防除金钟藤试验研究

Experiment of Chemical Control for Merremia boisiana with the Benzoate Aqueous Solution

在秋季，应用苯甲酸盐水剂对金钟藤进行挂瓶滴加的防除试验，结果表明：5％的苯甲酸盐水剂滴加24～36h最经济有效，防除金钟藤效果达100％；用药量与金钟藤藤茎的直径成正比。在1～6em藤茎范围内，用药量在50～200ml范围增减。

In the autumn, the experiments of Chemical Control were carried out using the benzoate aqueous solution which was dripped to Merremia boisiana （ Gagn. ） van Ooststr from a hanging bottle. The results of the trial indicated that 50ml/L benzoate aqueous solution was the most economic and efficient by dripped to Merremia boisiana（ Gagn. ）van Ooststr for 24 -36 hours, the control effect reached 100% ; The dosage was direct proportional with the diameter of rattan of Merremia boisiana （ Gagn. ） van Ooststr. The dosage was in 50 - 200 ml scope in 1 6 cm diameter of rattan scope.
