摘　　要：通过量筒法筛选助剂研制生防菌AM53的水分散性粒剂,并测定其林间防治效果.结果表明:水分散粒剂的最佳配方为:3.5%十二烷基硫酸钠(润湿剂),5%木质素磺酸钠(分散剂),4%硫酸铵(崩解剂),2%聚乙二醇(粘结剂),加水量16%-20%,高岭土补足100%.货架期试验结果表明,该粒剂常温下至少能贮存3-4个月.林间防治试验结果表明,AM53菌剂对杉木炭疽病有较好的防治效果.The water dispersible granule （WDG） with strain AM53 was developed by measuring cylinder method, and the control effect of forest on anthracnose disease was also determined. The optimal WDG formulation was as follows： 3.5% SDS ＋ 5% sodium lignosulfonate ＋ 4% （ NH4 ） 2 SO4 ＋ 2% PEG. The granule could be preserved at least for 3 - 4 months at normal temperature. The re- sult showed that the forest control effect of antagonistic bacteria AM53 on Colletotrichum gloeosporioides was good.
