摘要
[目的]探讨磺酰磺隆对小麦田杂草的除草活性。[方法]采用室内生物测定方法测定了磺酰磺隆对11种麦田杂草的除草活性,并在小麦田进行了田间试验。[结果]温室试验表明:磺酰磺隆对荠菜、菵草和硬草有很好的防除效果,ED50值分别为1.49、0.98、5.33 g a.i./hm2;对猪殃殃、麦家公、麦瓶草也有较好的效果;对野燕麦等有较好的抑制生长作用,但对播娘蒿、节节麦效果较差。田间试验表明:磺酰磺隆对猪殃殃杂草等均有较好的防效且对小麦安全。[结论]磺酰磺隆可以应用于小麦田防除多种杂草。
Sulfosulfuron is a new registered herbicide in our country.The paper aims to determine the biological activity and weed control effect of sulfosulfuron.[Methods] The whole plant dose-response experiments were conducted to evaluate the efficacy of sulfosulfuron on 11 major weeds growing in pots in glasshouse.Sulfosulfuron was applied postemergence to plots arranged in a randomized complete block design with four replications in wheat fields.[Results] The result of experiments in glasshouse showed that the sulfosulfuron had best effect on Capsella bursapastoris,Beckmannia syzigachne,Sclerochloa kengiana with the ED50 of 1.49,0.98,5.33 g a.i./ha respectively,displayed better effect on Galium？spurium,Lithospermum arvense,Silene conoidea,and had good inhibition on the growth of Lolium multiflorum,Avena fatua,Bromus japonicus.It only had slightly control effect or no effect to Descuminia sophia and Aegilops tauschii.The results of field experiments also showed that sulfosulfuron had better control on Lamium amplexicaule,Galium aparina,Silene conoidea,Lithospermum arvense without causing injury to wheat.[Conclusions] It was illustrated that sulfosulfuron could be applied in wheat fields to control most broadleaf and grass weeds.
