Weed Control, Rice Safety, and Mechanism of the Novel Paddy Field Herbicide Glyamifop

Glyamifop (R&D code: FG001), (R)-(2-(4-(6-chlorobenzoxazol-2-oxy) phenoxy) propionyl) glycine ethyl ester is a newly developed aryloxyphenoxypropionate (HRAC Group 1) herbicide for weed control in paddy fields. This work determined the effect of on weeds and its safety rice glasshouse. controlled common gramineous fields at 100 g a.i. ha−1: fresh weight inhibition rates Echinochloa crus-galli, Leptochloa chinensis, Setaria viridis, Eragrostis japonica, Digitaria sanguinalis Panicum bisulcatum were all above 90%. It has almost no inhibitory broad-leaved cyperaceae weeds, such as Eclipta prostrata Cyperus iria. inhibited cyhalofop-butyl-resistant L. penoxsulam-resistant E. crus-galli quinclorac-resistant crusgalli var. zelayensis by 100%, 99.98% 96.37%, respectively, ha−1, based weight. The selectivity index foliage treatment varieties japonica ‘Huaidao 5’, indica ‘Xiangliangyou 900’ glutinous ‘Zhennuo 29’ was 5.93, 6.81 4.91, respectively; therefore, safe 3 different varieties. Fresh 7.18%, 2.99% 7.93% 2.5-, 3.5- 5.5-leaf stage, 5.18, 6.04 7.93, indicating that these leaf stages. chinensis ACCase activity decreased with increasing concentration, similar to cyhalofop acid; this confirmed an inhibitor. In conclusion, potential management it good against are resistant herbicides
