用拌种剂进行种子处理,是防治种子和土壤传播病害的一项简便、经济、有效的增产措施。自西力生等汞制剂停用后,禾谷类黑穗病、棉花苗期病害又有所抬头,有的地区黑穗病率高达40%以上。近几年推广使用了一些新的非汞杀菌剂,发病率开始下降,特别是内吸性杀菌剂的推广使用,效果很好。内吸性杀菌剂,既可防治种子表面带菌,又可防治种子内部的病原菌;内吸性杀菌剂进入发芽的种子并向上传导,既可保护出芽的幼苗,还 Seed dressing with seed dressing is a simple, economical and effective stimulant for the control of seed and soil-borne diseases. Since the withdrawal of other mercury preparations such as Xili, cereal smut and cotton seedling diseases have also been on the rise, in some areas smut as high as 40% or more. In recent years, the promotion of the use of some new non-mercury germicide, the incidence began to decline, especially the promotion of the use of systemic fungicide, the effect is very good. Internal absorption fungicide, both on the surface of seed prevention and control, but also the prevention and treatment of pathogens within the seed; systemic fungicide germination into the seeds and conduction upwards, both to protect budding seedlings, but also
