为了评价春雷霉素在水稻上使用的安全性，建立其使用规范，2010-2011年在河南、黑龙江和江苏3地进行了10%春雷霉素可湿性粉剂在水稻上的消解动态和最终残留试验。消解动态试验结果表明：春雷霉素在水稻田水和植株中的半衰期分别为0.97～2.70 d和1.00～2.18 d。最终残留试验表明：10%春雷霉素可湿性粉剂按推荐剂量(40 g/hm2)和1.5倍推荐剂量(60 g/hm2)在病害发生期施药3～4次，末次施药后14,21,28 d，春雷霉素在糙米中残留量≤0.022 mg/kg，稻壳中≤0.269 mg/kg，植株中≤0.159 mg/kg，土壤中≤0.005 mg/kg。
為瞭評價春雷黴素在水稻上使用的安全性，建立其使用規範，2010-2011年在河南、黑龍江和江囌3地進行瞭10%春雷黴素可濕性粉劑在水稻上的消解動態和最終殘留試驗。消解動態試驗結果錶明：春雷黴素在水稻田水和植株中的半衰期分彆為0.97～2.70 d和1.00～2.18 d。最終殘留試驗錶明：10%春雷黴素可濕性粉劑按推薦劑量(40 g/hm2)和1.5倍推薦劑量(60 g/hm2)在病害髮生期施藥3～4次，末次施藥後14,21,28 d，春雷黴素在糙米中殘留量≤0.022 mg/kg，稻殼中≤0.269 mg/kg，植株中≤0.159 mg/kg，土壤中≤0.005 mg/kg。

In order to evaluate the safety and establish the regular use of kasugamycin in rice field, the field trials for kasugamycin 10% WP were conducted in Henan, Heilongjiang and Jiangsu in 2010-2011. The results from field experiment of degradation dynamic indicated that the half-lives of kasugamycin in water and rice plant were 0.97-2.70 d, 1.00-2.18 d, respectively. The final residue indicated that when the rice plant was sprayed 3-4 times with 10%kasugamycin WP at the active ingredient dosage of 40 g/hm2 and 60 g/hm2, the total residues of kasugamycin in brown rice, rice husk, rice plant and soil were less than 0.022 mg/kg, 0.269 mg/kg, 0.159 mg/kg and 0.005 mg/kg on 14th, 21th, 28th days after the last spraying, respectively.
