Penoxsulam is a post-emergence triazolopyrimidine sulfonamide herbicide which is widely used for the control of annual grasses and broadleaf weeds in rice cultivation. It is suspected to pose a potential risk for aquatic and terrestrial plants as well as for soil microbial communities. Recently, more and more attention has been focused on the quantitatively study of the fate, and transformation of penoxsulam in rice field. In this review, the research progresses on adsorption and dissipation behaviors of penoxsulam in rice paddy systems were summarized and analyzed in detail. It is suggested that studies investigating penoxsulam adsorption onto soil is limited, and little research focused on the transport of penoxsulam in soil and water system has been conducted. Furthermore, the risk assessment of the effect of pesticide on soil and water environment should be strengthened.
