Mobility of two sulfonylurea herbicides in soil
1990
Beckie, H.J. | McKercher, R.B.
Intact field soil cores were used to compare the mobility of DPX-A7881 [2-[[[[[4-ethoxy-6-(methylamino)-1,3,5-triazin-2-yl]amino]carbonyl]amino] sulfonyl]benzoate], a new sulfonylurea herbicide, and chlorsulfuron [2-chloro-N-[[(4-methoxy-6-methyl-1,3,5-triazin-2-yl)amino]carbonyl]benzen esulfonamide] in four soils. DPX-A7881 was generally less mobile than chlorsulfuron in soil. This was explained on the basis of the reduced water solubility of DPX-A7881 relative to chlorsulfuron (1.7 and 300 ppm, respectively, at pH 5.0). Enhanced mobility of both herbicides in soil was related to higher soil pH and low organic matter content.
