Herbicide resistance

A study was conducted to find out the extent of wild oat problems throughout Turkey including herbicide resistance. This paper includes results of determining the herbicide resistance status of AVELU populations to ACCase and ALS inhibitors that are fenoxaprop (Fen), pinoxaden (Pin), tralkoxydim (Tra), mesosulfuron+iodosulfuron (MeI), and proxycarbazone+mesosulfuron (PrM). AVELU seeds were collected from 213 wheat fields throughout Turkey in 2014–2015 and the response to selected five herbicides was tested under screen-house.

Research and production of clean, high-quality and high-yield rice, sustainable environmental protection are the most important and important tasks of many countries in the world as well as in Vietnam today. Therefore, the research, selection and creation of rice varieties that are both high-yield and resistant to pests, weeds, and climate change, in order to minimize the use of herbicides and pesticides.

Prime editing is a novel and universal CRISPR/Cas-derived precision genome-editing technology that has been recently developed. However, low efficiency of prime editing has been shown in transgenic rice lines. We hypothesize that enhancing pegRNA expression could improve prime-editing efficiency.

Asia minor bluegrass (Polypogon fugax, P. fugax), a weed that is both distributed across China and associated with winter crops, has evolved resistance to acetyl-CoA carboxylase (ACCase) herbicides, but the resistance mechanism remains unclear. The goal of this study was to analyze the transcriptome between resistant and sensitive populations of P. fugax at the flowering stage.

This study reports on glyphosate resistant (GR) weeds and their resistance mechanisms based on global scientifically reported cases. Forty-nine different weed species have evolved resistance to glyphosate in 29 countries with a total of 318 identified cases worldwide. Fifty percent of these resistance cases were found in glyphosate-resistant cropping systems.

The conventional use of the same post-emergence herbicides repeatedly may result in poor management of the early weed flush in wheat under zero-tilled (ZT) condition. This may hasten development of herbicide resistant weeds as well. In this study, a possible weed management has been envisaged in ZT and conventional till (CT) wheat during 2013-14 and 2014-15 using tillage and weed control treatments. It was observed that ZT caused a considerable reduction in the population of narrow-leaved, broad-leaved and total weeds compared to CT.

Presence of diverse weed flora during critical period of crop-weed competition, is one of the major obstacles in conservation agriculture that reduces which can reduce the crop yield appreciably significantly. During critical period of crop-weed competition, chemical method of weed control is by far the most preferred way to minimize the weed infestation of weeds, farmers are mostly relying on chemical methods of weed management.

Rotation of rice-wheat cropping system is most popular in India due to its high productivity; however, these crops are highly infested by the varied weeds, thus farmers use various herbicides for their control. Resulting, this rotation consumes a large quantity of herbicides, which has resulted in severe problems like environmental and human health hazards; development of herbicide resistance in weeds etc.

Widespread resistance in Phalaris minor is a major challenge for sustainable productivity. Recent increases in the development of herbicide resistance in Phalaris minor worldwide demand a high up strategies to control this weed. Herbicide-resistant weeds are a constraint to weed management. The use of potential management strategies is crucial in assuring sustainable production. A pot-culture experiment was conducted during the winter season of 2017-18 with the objective to evaluate the herbicidal efficacy for management of isoproturon-resistant Phalaris minor.

The increased selection pressure of the herbicide glyphosate has played a role in the evolution of glyphosate-resistance in weedy species, an issue that is becoming a threat to global agriculture. The molecular components involved in the cellular toxicity response to this herbicide at the expression level are still unidentified.

Herbicide resistance in weedy plant populations can develop through different mechanisms such as gene flow of herbicide resistance transgenes from crop species into compatible weedy species or by natural evolution of herbicide resistance or tolerance following selection pressure.

Direct seeded rice having weed diversity in a substantial amount and the use of single herbicide for weed management is ineffective to control the wide range of weed hence chances of weed flora shift and herbicide resistance in weeds is expected. So to study the efficacy of herbicide mixtures in wet direct seeded rice, an experiment was conducted at Institute Research Farm of ICAR-National Rice Research Institute, Cuttack (Odisha) during kharif season of 2017.

It was examined that weeds cause a lot of problems in the crop field. Weeds compete with the main crop for nutrients, water, food, space, sunlight etc. Weeds utilize the nutrients provided to the main crop and sometimes dominate the main crop. Some weeds are very noxious and they are harmful for both humans as well as animals. It is clearly revealed from studies done in field of weeds that use of herbicides used to control weeds cause many effects on soil as it leads to degradation in the quality of soil, water as well as it pollutes environment.

Traditional agricultural practices have resulted in decreased soil fertility, shortage of water resources and deterioration of agricultural ecological environment, which are seriously affecting production of maize. A field experiment was conducted in medium black soil during kharif and rabi season of 2016-17 and 2017-18 at farmer field near Agricultural Research Station, Sirguppa. The results revealed that, among improved production technologies of maize, higher grain yield were noticed with improved method-4 (T5: 7681 kg ha-1 ) over farmer method of cultivation (T1:5840 kg ha-1 ).

Invasive species (weeds) contribute to great losses in crop productivity, and one of the strategies for controlling their distribution in the field involves the use of herbicides. However, the development of new formulations for the control of weeds is challenged by environmental issues, increases in the resistance of weeds to herbicides, and poor selectivity of herbicides towards invasive species.

Rice (Oryza sativa L.) is among the most important food crops that provide a staple food for nearly half of the world’s population. Rice crops are prone to various types of stresses, both biotic and abiotic. Biotic stresses include insect pests, fungus, bacteria, viruses, and herbicide toxicity. Among abiotic stresses, drought, cold, and salinity are also well studied in rice.
