Systemic Property of Clacyfos

The absorption and translocation properties of clacyfos were evaluated in the greenhouse at the National Pesticide Discovery South Center in (Zhejiang) in China. Common amaranth (Amaranthus retroflexus) was used as the target plant. The data in Table 8.7 showed that clacyfos would be absorbed through buds, roots, stems, and leaves and demonstrated its inhibitory effect against plant growth. 

Clacyfos exhibited xylem mobility. It exhibited good inhibitory effect on plant growth through either foliar and stem spray or root application. The inhibitory effect was most significant through foliar application. Therefore, clacyfos is recommended as a post-emergence, foliage-applied herbicide.
