苹果树腐烂病是我省苹果产区一种毁灭性病害。目前,生产上一般采用的刮治方法,虽有一定作用,但病疤复发率高,费工,且刮治后留有伤疤,影响果树的生长发育。我所自1971年以来,与省内有关园艺场和社、队十余个单位协作,开展了综合防治试验。其中药剂防治以10倍农“四平液”效果显著。1972-1975年共涂病疤495块,当年治疗效果达80-100％。涂药病疤经室内分离培养证实,田间试验结果可靠。 Apple tree rot disease is a devastating disease in apple producing areas in our province. At present, the commonly used method of scraping and curing in production has a certain effect, but the recurrence rate of the scar is high, and it takes a lot of work, and scars are left after the cure, which affects the growth and development of the fruit tree. Since 1971, we have conducted comprehensive prevention and control experiments in collaboration with more than 10 units of the horticultural field, community and teams in the province. One of the pesticides to control 10 times the “Siping fluid” effect is significant. Between 1972 and 1975, a total of 495 blisters were treated, and the treatment effect reached 80-100%. Application of drug isolated laboratory isolates confirmed the field test results are reliable.
