Black-grass (Alopecurus myosuroides Huds.) is a common weed in Chinese wheat fields, and has become troublesome due to its evolution of herbicide resistance. One black-grass population (HN-14) collected from field where herbicides were applied was suspected be resistant (R) mesosulfuron-methyl. This study aims establish cross-resistance pattern explore potential resistance mechanisms. The resul...

A field experiment was conducted in a split-plot design with 3 replications at Research Farm, College of Agriculture, Jawaharlal Nehru Krishi Vishwa Vidyalaya, Jabalpur (Madhya Pradesh), during the rainy (kharif) season 2019, to evaluate performance different herbicides direct-seeded rice (Oryza sativa L.). The comprised 2 main plots, viz. rainfed and irrigated, 8 weed-control treatments, bispy...

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...

Quizalofop-p-ethyl (QPE) is a post-emergence herbicide that effectively controls grass weeds and is often detected in the environment. However, the biochemical and molecular mechanisms of QPE degradation in the environment remains unclear. In this study, a highly effective QPE-degrading bacterial strain J-2 was isolated from acclimated activated sludge and identified as a Pseudomonas sp., conta...

Abstract Mefenpyr-diethyl is a foliar-acting safener of the pyrazoline chemical group, and after its absorption, metabolization detoxification herbicides occur in treated plants. Studies have demonstrated protective effect this for herbicide fenoxaprop-P-ethyl grass. Thus, work aimed to evaluate whether tank mixture mefenpyr-diethyl has response haloxyfop-methyl non-perennial bahiagrass. The ex...

Abstract In the mid‐southern USA, rice ( Oryza sativa L.) is flooded primarily to suppress weed germination and growth. Two experiments were conducted determine whether herbicide performance in conventional or Clearfield control programs was affected by intermittent flooding. The effects of flooding program on barnyardgrass Echinochloa crus‐galli (L.) P. Beauv) control, grain yield, water appli...

Weed management is the major biological constraint in paddy (Oryza sativa L.) producing areas. Predominantly, barnyard grass (Echinochloa crus-galli) a rice-mimicking weed that causes 57% of yield loss rice production. Conventionally, herbicides are site-specific inhibitors often used to suppress E. crus-galli growth. Acetyl-CoA carboxylase (ACCase) an important target for developing novel with...
