Multiple resistance to thifensulfuron-methyl and fomesafen in redroot pigweed ( Amaranthus retroflexus L.) from China

ABSTRACT Redroot pigweed (Amaranthus retroflexus L.) is a troublesome weed infesting soybean (Glycine max [L.] Merr.) productions in China. One redroot pigweed population, collected from Heilongjiang (HLJ) Province, China, was suspected to be resistant to thifensulfuron-methyl and fomesafen. The oth...
