我们是于1988年开始引进推广生物农药“农抗120”防治苹果树腐烂病技术的,几年来,经在我县邙岭、岳滩、缑氏等果园进行试验,示范,效果十分明显。病症当年治愈率达100％,并且没有再发现复发现象。伤口两年可愈合2—3厘米,与常用药剂福美砷对比药效相当,但促进伤口愈合的能力较福美砷要好的多,且无残毒、无污染、费用低,确是目前防治苹果树腐烂病理想的生物农药。其具体做法是: 1、坚持常年刮治,特别是春(3—4月份)秋(9—10月份)腐烂病发生高峰期,要仔细查找病疤,先在发病部位用利刀将病皮坏死组织连同周缘
We started in 1988 to promote the introduction of bio-pesticides, “agricultural anti-120” prevention and treatment of apple tree rot disease technology, the past few years, in my county Huang Ling, Yue Beach, Cheshire and other orchards to test, demonstration, the effect is very obvious. Disease cure rate was 100% year, and no recurrence was found. Wound heal 2-3 cm two years, with the commonly used drugs Fu Mei Arsenide relatively comparable efficacy, but the ability to promote wound healing is better than Fumei arsenic, and no residue, no pollution, low cost, is indeed the prevention and treatment of apple tree decay Pathological biological pesticide. The specific approach is: 1, adhere to the perennial cure, especially in the spring (March-April) autumn (September-October) rot disease peak, to carefully find the scar, the first place in the incidence of disease with a knife Necrotic tissue along with the periphery
