2005—2006年,我们开展了10%多.福悬浮剂田间防治苹果枝干轮纹病试验。试验结果表明,采取全株枝干涂抹处理的方式要优于喷雾处理,2次处理的防治效果要明显优于1次处理,10%多.福悬浮剂5、10倍液全株枝干涂抹处理防效分别为82.61%和69.57%;精确病斑分离条件下,10%多.福悬浮剂5、10倍液枝干涂抹处理防效分别为70%和60%,较为理想;10%多.福悬浮剂的合理使用技术为:采取枝干轻刮条件下,以10%多.福悬浮剂5倍液进行全株涂抹,适宜使用时期为4月中下旬,使用次数为2次,间隔10天左右。
From 2005 to 2006, we carried out more than 10% .Floral suspending agent in the field to prevent and cure apple branch rotten test. The results showed that the method of applying the whole plant stem branch smear treatment was better than the spray treatment, and the control effect of the two treatments was obviously better than that of the first treatment and more than 10% The control effect was 82.61% and 69.57% respectively, and under the condition of precise lesion separation, more than 10% The rational use of the technical parameters of blessing suspension agent is as follows: under the conditions of dry and light shaving of branches, the whole plant is coated with 5 times of blessing suspension concentrate 5 times, the suitable period of use is mid-to-late of April, the number of use is 2 times, 10 days or so.
