Book CHEMCIAL CONTROL OF GRASSY WEEDS IN WHEAT  TRITICUM AESTIVUM L

Download or read book CHEMCIAL CONTROL OF GRASSY WEEDS IN WHEAT TRITICUM AESTIVUM L written by Muhammad Yasin and published by LAP Lambert Academic Publishing. This book was released on 2011-02 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wheat is the most widely grown cereal grain crop and staple food of people in the world. Among many other factors of low yield in wheat, one of the most serious but less addressed causes is the presence of weeds. Weeds compete with crops for nutrients, light, space, moisture and cause reduction in wheat vigor, tillering, head size, kernel weight. Weeds lower the market value of the produce and hence bring economic losses to the growers. Chemical weed control is preferred over other weed control methods like manual weeding, mechanical weeding, intercropping, crop rotation and stale seed bed technique because it is quick, more effective and relatively cheaper. Grassy (narrow leaved) weeds like Phalaris minor, Avena fatua, Hordeum vulgare and Cyperus rotandus are the serious problem in wheat.This book describes identification of different grassy weeds present in wheat fields and most economical herbicides for controlling these weeds, especially against P. minor.

Book Efficacy of Separate and Premix Formulation of Herbicides on Weeds

Download or read book Efficacy of Separate and Premix Formulation of Herbicides on Weeds written by Rakesh Kumar and published by LAP Lambert Academic Publishing. This book was released on 2013 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wheat (Triticum aestivum L.) is second most important food grain crop of India and is associated with the food security of the country.India needs more food around 105 million tonnes for feeding the increasing population by 2020 A.D. and this demand has to be met primarily from wheat crop as this is the only assured food crop which production and productivity could be sustained. Further wheat area is decreasing every year and there is very little scope for expansion of area in the future. So there is urgent need to vertical increase in yield per hectare to ensure household food security.Herbicide rotation and use of herbicide mixture are two major strategies to prevent the selection of resistant biotypes of a weed species. Herbicides with different mode of action when mixed together, bind to different target site in weeds and prevent the probability of target site resistance in susceptible species. Today, most of the commercially available herbicides are mixture of grassy and non-grassy herbicides and have efficiency against these types of weeds only. Therefore, targeted weed control mixtures are required to prevent resistance in one or more weed species.

Book Chemical Weed Control in Wheat  Triticum Aestivum L

Download or read book Chemical Weed Control in Wheat Triticum Aestivum L written by M. Asif Shehzad and published by LAP Lambert Academic Publishing. This book was released on 2011-04 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wheat (Triticum aestivum L.) is an important cereal crop of the world and staple food of Pakistan's people. Over the last few years, weed flora infestation has become a key disaster in crop production. The quality of wheat produce from weed infected fields is inferior because these compete with crop plants for space, light and nutrients, harbor plant pathogens, create hurdles in cultural practices and mixing of their seeds with wheat grains. Owing to weeds infestation, tremendous changes in crop production have been assumed all over the world. This book, therefore, focuses on the use of different post emergence herbicides to reduce growth and spread of weeds from reaching at mature stage when they are extremely harmful to wheat plants. The importance of weed control in achieving better production of wheat is discussed in the light of results.

Book Competitive Effects and Control of Weeds in Winter Wheat on the Anatolian Plateau  Turkey

Download or read book Competitive Effects and Control of Weeds in Winter Wheat on the Anatolian Plateau Turkey written by Cengiz Tezel and published by . This book was released on 1975 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wheat is the major crop produced on the Anatolian Plateau of Turkey. Annual weeds cause large yields reductions in the wheat crop. Several formulations of 2, 4-D and mixtures of 2, 4-D and 2,4, 5-T are the only materials currently available for use in Turkey on wheat. The objective of this study was to determine the optimum time for application of herbicides in order to reduce competition between winter wheat (Triticum aestivum cv. 'Bolal') and annual weeds. Several herbicides and herbicide mixtures were compared for their effectiveness against two major weed species, yellowweed (Boreava orientalis L.) and cornflower (Centaurea cyanus L.). Herbicides were applied at three different dates according to growth stages of wheat and weeds. Two series of handweeded plots were also included. One set allowed weed competition with the wheat for 4 and 8 weeks and was handweeded for the remainder of the season. The other set was kept free of weeds for 4 and 8 weeks and left weedy for the remainder of the season. Weed-free and weedy control plots were included. Wheat which was free from weed competition in the early part of the growing season produced the highest yields. Plots on which herbicides were applied at the earliest date produced higher yields than where herbicides were applied later. Optimum time for herbicide application was when wheat was in the two to three tiller stage and weeds were small, five to six leaf stage. Delaying the application of herbicides beyond the critical period of competition, which is determined by stage of growth of weeds and wheat, resulted in a continuing decrease in wheat yields. Chemicals which produced satisfactory weed control and increased wheat yields were, 2,4-D, 2,4-D + 2,4,5-T, bromoxynil + MCPA, and terbutryn + 2,4-D combinations. The terbutryn + 2,4-D combination needs further research because of possible phytotoxicity to wheat. It was concluded that using only herbicides now available in Turkey, wheat yield increases of 25 to 50% or more are possible by applying herbicides at the optimum time.

Book Management of Invasive Weeds

Download or read book Management of Invasive Weeds written by Inderjit and published by Springer Science & Business Media. This book was released on 2008-12-17 with total page 361 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biological invasions are one of the major threats to our native biodiversity. The magnitude of biodiversity losses, land degradation and productivity losses of managed and natural ecosystems due to invasive species is enormous. The ecological and environmental aspects of non-native invasive plants are of great importance to (i) understand ecological principles involved in the management of invasives, (ii) design management strategies, (iii) find effective management solutions for some of the worst invaders, and (iv) frame policies and regulations. The objectives of this book are to discuss (i) ecological approaches needed to design effective management strategies, (ii) recent progress in management methods and tools, (iii) success and failure of management efforts for some of the worst invaders, and (iv) restoration and conservation of invaded land. In an effort to achieve these objectives, contributing authors have strived to provide up-to-date information on the management of non-native invasives. Chapters included in the book are peer-reviewed by international experts working in the area. Readers will get a unique perspective on ecological aspects of the management of invasives. The book will be useful to graduate students, researchers, managers and policy makers involved in the management of exotic invasives.
