Public awareness and environmental policies have increased interest in applying non-herbicide weed control methods conventional farming systems. Even though mechanical has been used for centuries agricultural practice, continuous developments—both terms of implements automation technologies—are continuously improving the potential outcomes. Current were evaluated their efficacy effects on yield...

Reniform nematode (Rotylenchulus reniformis) resistance is being transferred to Gossypium hirsutum from its distant relatives. Reports of fluometuron damage to LONREN lines with nematode resistance from G. longicalyx raised concerns about introducing herbicide sensitivity from other nematode resistance sources. The research objective was to evaluate 15 sources of reniform nematode resistance fo...

Target-site and non-target-site herbicide tolerance are caused by the prevention of herbicide binding to the target enzyme and the reduction to a nonlethal dose of herbicide reaching the target enzyme, respectively. There is little information on the molecular mechanisms involved in non-target-site herbicide tolerance, although it poses the greater threat in the evolution of herbicide-resistant...

The interaction between environment and genetic traits under selection is the basis of evolution. In this study, we have investigated the genetic basis of herbicide resistance in a highly characterized initially herbicide-susceptible Lolium rigidum population recurrently selected with low (below recommended label) doses of the herbicide diclofop-methyl. We report the variability in herbicide re...

Garlic mustard, an invasive exotic biennial herb, has been identified in the Upper Peninsula of Michigan, but is not yet widely distributed. We tested the effectiveness and impact of management tools for garlic mustard in northern hardwood forests. Six treatment types (no treatment control, hand-pull, herbicide, hand-pull/herbicide, scorch, and hand-pull/scorch) were applied within a northern h...

A reduced herbicide rate with hand-weeding (HW) can act as a safer and sustainable approach for weed control. field study was conducted at CSIR-IHBT, Palampur, India during 2018 2019 to analyze the efficacy of herbicides in combination manual weeding on control yield wild marigold (Tagetes minuta L). The experiment laid 12 treatments, consisting two dosages prescribed rates (R) pendimethalin, i...

Wild oat is a nuisance monocot weed mainly in cereal canopies. The increasing problem of herbicide resistance and the implementation integrated pest management includes use seed meals from species with allelopathic potential. This study aimed to assess efficacy as an environmentally friendly alternative for control herbicide-susceptible (S) -resistant (R) wild biotypes. A pot experiment was car...

Herbicide resistant crops are commercially advantageous for efficient field productivity by enabling use of nonselective herbicides for weed management. Herbicide resistant trees could be used to improve productivity and reduce the costs of forest management through to the first and second years post tree establishment. We describe the introduction of the phosphinothricin acetyltransferase (bar...

Genetic modification of crop plants has promoted concerns about potential environmental effects of this new technology. In this essay, I will discuss the environmental effects of genetic modification of crop plants using herbicide resistance as an example. Considering herbicide resistance as an old agricultural trait, it is difficult to find any reason to assess the environmental risks of genet...
