摘 要：
为筛选施用适期宽、适应性广、安全高效的除草剂新品种,通过大田示范验证47%异隆·丙·氯吡可湿性粉剂在江苏省沭阳县水稻旱直播田、机插秧田、手插秧田适期适量施用对杂草的防效及对水稻的安全性。结果表明,47%异隆·丙·氯吡可湿性粉剂在旱直播水稻播后苗前或立针期以2 100 g/hm~2喷雾处理、在机插秧水稻移栽3 d前以1 050 g/hm~2粗喷雾法处理结合移栽7 d后以1 050 g/hm~2毒肥法处理、在手插秧水稻移栽6 d后以1 050 g/hm~2毒土法处理对江苏省沭阳县稻田稗属杂草、马唐、千金子、丁香蓼、异型莎草等杂草的株防效和鲜质量防效均高于91%,且对水稻安全。

摘 要：
Field experiments were carried out to investigate the efficacy and selectivity of halosulfuron-methyl ·pretilachlor· isoproturon 47% wettable powder( WP) in dry direct-seeded rice field,mechanized transplanting rice field,and artificial transplanted rice fields in Shuyang County of Jiangsu Province. The formulated mixture was safe to the rice when sprayed at 2100 g/hm~2 before seedling and during vertical needle period after dry direct-seeding of rice at 1 050 g/hm~2 before and after mechanized transplanting,and at 1 050 g/hm~2 after artificial transplanting in paddy fields. The foliage-control effect and the fresh-weight control effect of the mixture were above90%,including for Echinochloa spp.,Leptochloa chinensis, Digitaria sanguinalis, Ludwigia prostrata,and Cyperus spp.
