Resistance to ACCase-inhibiting herbicides in an Asia minor bluegrass (Polypogon fugax) population in China.
Asia minor bluegrass (Polypogon fugax) is a common annual grass weed of winter crops distributed across China. We conducted a study on the resistance level and the mechanism of resistance to ACCase-inhibiting herbicides in a P. fugax population from China. Whole-plant dose-response experiments in greenhouse showed that the resistant P. fugax population was 1991, 364, 269, 157, and 8-fold resist...
متن کاملMutations in the plastidic ACCase gene endowing resistance to ACCase-inhibiting herbicide in Phalaris minor populations from India
Littleseed canarygrass (Phalaris minor Retz.) is one of the most common and troublesome weeds infesting wheat crop in India. Repeated use during the last two decades of the ACCase-inhibiting herbicide (clodinafop) to control this weed has resulted in the occurrence of resistance. Fifty-three P. minor populations were collected from wheat fields in Haryana and Punjab states of India. The dose-re...
متن کاملBroad Resistance to ACCase Inhibiting Herbicides in a Ryegrass Population Is Due Only to a Cysteine to Arginine Mutation in the Target Enzyme
BACKGROUND The design of sustainable weed management strategies requires a good understanding of the mechanisms by which weeds evolve resistance to herbicides. Here we have conducted a study on the mechanism of resistance to ACCase inhibiting herbicides in a Lolium multiflorum population (RG3) from the UK. METHODOLOGY/PRINCIPAL FINDINGS Analysis of plant phenotypes and genotypes showed that a...
متن کاملNon-target-site-based resistance to ALS-inhibiting herbicides in six Bromus rigidus populations from Western Australian cropping fields.
BACKGROUND Bromus rigidus is a common weed species that has increased in cropping fields owing to limited control options. During a random field survey in Western Australia, six B. rigidus populations that had survived in-crop weed control programmes were collected. The study aimed to determine the resistance profile of these six populations. RESULTS Based on dose-response studies, all six B....
متن کاملA novel amino acid substitution Ala-122-Tyr in ALS confers high-level and broad resistance across ALS-inhibiting herbicides.
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 ...
