通过剔削已感染的组织,经53～55℃热水浸渍20分钟或在室温下用杀线虫剂浸渍(600ppm灭克磷,20分钟;250ppm苯胺磷,10分钟;1000ppm草氨酰,20分钟;5000ppm二溴氯丙烷,1分钟)等方法,可减少定植材料的钻孔线虫数量。热水浸渍必需结合重削预处理方能奏效;但若用灭克磷、苯胺磷和二溴氯丙烷浸渍,采取轻削即可。 大田试验表明:用1000ppm草氨酰、苯来特和涕必灵的室温(23～25℃)溶液或53～55℃热溶液浸渍20分钟处理的植株,其萌芽、早期生长和果穗重量均不比一般热水处理的好。
The infected tissue was removed by ticking the infected tissue, immersed in hot water at 53-55C for 20 minutes, or nematicide-impregnated at room temperature (600 ppm fenfluosin, 20 minutes; 250 ppm aniline phosphate, 10 minutes; 1000 ppm oxamide, 20 minutes ; 5000ppm dibromochloropropane, 1 minute) and other methods, can reduce the number of colonized material drilling borers. Hot water immersion must be combined with heavy-cutting pre-treatment can be effective; but if the use of grams of phosphorus, aniline phosphorus and dibromo-chloropropane impregnated, you can take light cutting. The field experiments showed that the plants treated with 1000ppm oxalyl, beryl, and dipyridamole at room temperature (23 ~ 25 ℃) or the hot solution of 53 ~ 55 ℃ for 20 minutes had no difference in germination, early growth and ear weight General hot water treatment is good.
