马尾松赤枯病是由枯斑盘多毛孢(Pestalotia funerea Desm.)引起的病害。在我省发生面广,为害严重。70年代起就用“621”、“621”硫烟剂和“741”供热剂防治,效果虽好,但这些烟剂均含六六六成份。1983年国务院下达了停止六六六生产和使用的文件后,为了解决生产防治的问题,我们又选用了几种烟剂,经室内药效测定,1984年6月在达县铁山林场,以“741”供热剂为标准药剂,进行了大面积林间防治马尾松赤枯病药效对比试验。从中筛选出高效低毒不含六六六成份的安林杀菌烟剂2号(以下简称安林2号),平均防治
Masson Pine Blight is a disease caused by Pestalotia funerea Desm. In our province a wide range, serious harm. Since the 1970s, “621”, “621” sulfur smoke and “741” heat-control agent have been used to prevent and cure these pollutants. Although the effect is good, these smoke agents contain 666 ingredients. After the State Council issued a document on halting the production and use of 666 in 1983, in order to solve the problem of prevention and control of production, we also used several kinds of tobacco smoke. After indoor efficacy testing, in June 1984 at Tieshan Forest Farm in Daxian “741” heating agent as a standard pharmaceutical, carried out a large area of forest control of Masson’s pine blight efficacy comparison test. From which screening of efficient and low toxicity does not contain 666 ingredients of Anlin bactericidal smoke No. 2 (hereinafter referred to as Anlin 2), the average control
