Herbicide resistant weeds

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.

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.

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.

Water chickweed (Myosoton aquaticum (L.)) is a dicot broadleaf weed that is widespread in winter fields in China, and has evolved serious resistance to acetolactate synthase (ALS) inhibiting herbicides.

Waterhemp (Amaranthus tuberculatus (Moq.) J.D. Sauer) is a problem weed commonly found in the Midwestern United States that can cause crippling yield losses for both maize (Zea mays L.) and soybean (Glycine max L. Merr).

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.

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.

Moreover, during the past years, intensive and repeated applications of the same active ingredients cause the selection for and development of herbicide resistance (Devine & Shukla, 2000; Beckie, 2006; Gressel, 2009; Preston, 2004). Starting from 1960s, hundreds of weed biotypes have been reported as surviving herbicide application (Heap, 2011). Intensive efforts have thus been undertaken to discover new compounds with favorable environmental and safety features to selectively control weeds. In this regard, the photosynthetic system has been target aiming to find new weed killers.
