Herbicidal Activity in Greenhouse

Bioassay for clacyfos was carried out in the greenhouse for its pre- and postemergence herbicidal activity, selectivity, crop safety and biological property at National Pesticide Discovery South Center (Zhejiang) or National Pesticide Engineering Research Center (Nankai University, Tianjin) in Chain. The results are summarized as follows. 

1 Herbicidal Activity of Clacyfos in Different Growth Stages in Seedlings 

As shown in Table 8.3, clacyfos exhibited high herbicidal activity against dicotyledonous plants, rape, and common amaranth, at all growing stages at 450 g ai/ha.
