Amaranthus palmeri S. Watson (Amaranthaceae Juss.) is a dioecious noxious weed, native to the Americas, which infests summer crops. It causes high crop losses, and rapidly evolves resistance herbicides. In Europe, A. was recorded mostly as casual alien, but in 2018 it reported infesting soybean field Italy, next year two more populations were found same area. Experiments conducted on these thre...

Imidazolinone herbicides, which include imazapyr, imazapic, imazethapyr, imazamox, imazamethabenz and imazaquin, control weeds by inhibiting the enzyme acetohydroxyacid synthase (AHAS), also called acetolactate synthase (ALS). AHAS is a critical enzyme for the biosynthesis of branched-chain amino acids in plants. Several variant AHAS genes conferring imidazolinone tolerance were discovered in p...

BACKGROUND Wild radish, a problem weed worldwide, is a severe dicotyledonous weed in crops. In Australia, sustained reliance on ALS-inhibiting herbicides to control this species has led to the evolution of many resistant populations endowed by any of several ALS mutations. The molecular basis of ALS-inhibiting herbicide resistance in a novel resistant population was studied. RESULTS ALS gene ...

The algorithm is suggested for selecting most appropriate and sensitive bioassay method to a particular type of pollution prevailing in the study area. bases on battery bioassays, which necessarily includes mortality test Daphnia magna Straus, 1820. Other approaches comparing sensitivity methods are selected aim. has been tested model situ samples. According proposed algorithm, tests D. Cerioda...

Abstract Three suspected resistant (R1, R2, and R3) corn marigold populations collected from winter cereal fields located in central Greece were studied to confirm elucidate the mechanisms of resistance acetolactate synthase (ALS) inhibitors their competitive ability against barley. Whole-plant dose–response assays proved that three R highly cross-resistant ALS tribenuron, pyroxsulam + florasul...
