摘要
新农药“去丛灵”是作者用主效剂抗生素加增效剂、微肥剂复配而成。经过试验证明,去丛灵对泡桐丛枝病的防治有显著效果。用其注射泡桐平茬苗,造林后,防病效果达91.9％,注射一年生苗, 防病效果为80.0％;注射泡桐丛枝病苗,治愈率达92.3％;对3～4年生泡桐丛枝病树的治愈率为39.3％～84.7％,有效率为74.6％～91.1％。去丛灵对枣疯病、泡桐溃疡病和苹果腐烂病等也有良好的疗效。
A new biological Chemical—Antiwitche'sbroom, made up of main agent—antibiotic, synergisttr,ace elements and permeating agent, was produced in Henan Agricultural University. The results of biological assays of Antiwitche'sbroom showed that it yielded notable effect against Paulownia witche'sbroom. The cure rate of one year nurserystock and two—year cutting nurserystock were 80.8%and 91.9％respectively. To Paulownia nurserystock, the cure rate was 92.3%; to 3 or 4-year-old Paulownia trees 39.3%～84.7%.
