Herbicidal Activity of IG-IJ

1 Herbicidal Activity of 0,0-Dimethyl l-(Substituted Pbenoxyacetoxy)-l-(Fur-2-yl)Metbylpbospbonates IG [Pg.102]

Twenty-three of IG were prepared to test their herbicidal activity. The data of herbicidal activity of IG are listed in Tables 2.39, 2.40 and 2.41. [Pg.102]

The data in Table 2.39 showed (hat IG-19 (Y = 2-Cl,4-F) and IG-21 (Y = 2,4-Cl2) exhibited significant herbicidal activity against dicotyledons and monocotyledons for pre-emergence application comparable to 2,4-D at 1.5 kg ai/ha followed by IG-10 (Y = 4-Cl) and IG-15 ( = 3-Me,4-Cl). However all other compounds showed weak or no herbicidal activity against dicotyledons and monocotyledons for pre-emergence application at 1.5 kg ai/ha. [Pg.104]

On the basis of the preliminary bioassay, post-emergence herbicidal activity of most IG was further examined at 150 g ai/ha in the greenhouse. The results of postemergence herbicidal activity against rape, chingma abutilon, common amaranth, and white echpta are hsted in Table 2.41. [Pg.104]
