Effect and Safety of Bentazone Tank-mixed with Quizalofop-P-ethyl and Other Chemicals to Control Weeds in Sweet Potato Field
[Aims] The study was to investigate the feasibility of bentazone tank-mixed with quizalofop-P-ethyl,haloxyfop-R-methyl,fluazifop-P-butyl and clethodim to control weeds in sweet potato field.[Methods] Foliage spray trial was carried out to test the control effect and safety on sweet potato of 4 combinations.[Results] The results showed that all combinations performed high efficacy to Amaranthus retroflexus,Herba portulacae,Eleusine indica,Digitaria sanguinalis,Cyperus iria and some other representative weeds.After 40 days after application,the strain control effect was 83.0-89.7％ with fresh weight control effect of 87.5-93.3％.The application was safe to sweet potato,besides,the yield monitor of the sweet potato showed significant effect on weeds controling and yield increasing.[Conclusions] All combinations with characters of high efficacy,broad spectrum,safety and significant economic benefits should be popularized and used in field.
