在植物化学保护中,药剂种子消毒是重要的一环,是防治种子带菌、杜绝病菌源的主要措施。以往种子消毒使用最普遍,效果最好的是汞制剂——西力生。但是,由于西力生毒性强,残留量大、污染作物和水源,直接或间接地影响人、畜健康。据国外报导:日本稻田由于大量使用含汞杀菌剂,平均每粒稻谷中汞的残留量为0.1—0.22PPM。日本人民由于长期食用被汞污染的食物而引起“水俣病”,健康受到很大影响。省内外在使用汞剂过程中,由于使用不当,操作不
In the protection of phytochemicals, disinfection of pharmaceutical seed is an important part of the prevention and control of seed germs, the main measures to eliminate germs sources. In the past the most common use of seed disinfection, the best effect is the mercury preparation - Sibelium. However, due to the strong virulence of Xili, residues, pollution of crops and water sources, directly or indirectly affect people and livestock health. According to foreign reports: due to extensive use of mercury-containing fungicides in paddy fields in Japan, the average residue of mercury in each paddy is 0.1-0.22PPM. Japanese people are greatly affected by the “Minamata Disease” caused by long-term consumption of mercury-contaminated food. In and outside the province in the use of amalgam, due to improper use, the operation is not
