近三年开展了用保01等农药防治橡胶褐皮病的小区试验和中间试验,一年刮皮涂药3次,间隔期为3个月,第一次在胶树大落叶后至开割前进行。保01的使用浓度是500ppm。试验结果表明,在一般割胶强度下,对大田开割胶树进行环状刮皮涂施保01,可获得较好的防病增产效果。 Nearly three years to carry out the use of Paul 01 and other pesticides control brown gum disease cell trials and pilot trials, a year scraping the skin Tu medicine 3 times, the interval of 3 months, the first time in the gum tree leaves after the opening to cut Before proceeding. Paul 01 use concentration is 500ppm. The test results show that, under the condition of general tapping strength, the annular cuticle coating is applied to the tapping gum in the field to ensure the better anti-disease and yield-increasing effect.
