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 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.

This book was released on 1980 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the development of new selective herbicides and the frequent change in commercial wheat cultivars, information is needed as to the possible interaction between cultivars and herbicides. The responses of five genotypically diverse wheat cultivars (Bezostaya, Daws, Maris Hobbit, Stephens and Yamhill) to diuron [3-(3,4-dichloropheny1)-1,1- dimethylurea], diclofop methyl 2-[4-(2,4-dichlorophenoxy)phenoxy] propanoate and 2,4-D (2,4-dichlorophenoxy acetic acid) herbicides were compared under field and greenhouse conditions during the 1979-80 growing season. Grain yield was considered as a measure of herbicide injury when compared to the control plots for each cultivar. Effect on components of yield, plant height and grain protein content also were investigated. Differences in yield performance and related agronomic characters could be attributed to specific herbicides, designated rates and growth stages at the time of application. The lower (1.4 kg/ha) rate of diuron, diclofop and 2,4-D reduced yields less than the higher rate (2.8 kg/ha). Diuron and diclofop applied at the earlier (three to to five leaf) growth stage caused greater yield reductions than when applied at the later (five to six tiller) growth stage. Differential yield responses were found among and within the five winter wheat cultivars. The higher rate of diuron (2.8 kg/ha) caused the most injury in all of the cultivars tested. Major injury from diclofop occurred on the cultivar Maris Hobbit with minor effects on the other four cultivars. The primary reduction in yield from application of 2,4-D was to the cultivar Bezostaya. Among the five wheat cultivars tested in this experiment, Daws was the most tolerant to the three herbicides tested. Among the yield components (number of spikes per unit area, kernels per spike and 1000 kernel weight), number of kernels per spike accounted for most of the variation in yield. The data showed a direct relationship between kernel number and grain yield. Grain protein percentage of Daws, Maris Hobbit, Stephens and Yamhill significantly increased at the higher rate of diuron; whereas a similar increase was noted only in Bezostaya at the lower rate of 2,4-D. These increases in protein were associated with significant decreases in yield. Yield reductions due to herbicide treatments were generally lower than those due to weed competition. Reductions in yield and corresponding changes in the other agronomic characteristics observed in this experiment were the result of concentrations which are higher than those normally used in spraying wheat for weed control. This high chemical dosage was chosen for each herbicide to assure a greater differential response among and within the wheat cultivars. It also provided information for the plant breeder as to which cultivars had higher levels of tolerance. Such information is important when making hybrid combinations for the development of future varieties if higher levels of tolerance to specific herbicides are required.

Available in PDF, EPUB and Kindle. Book excerpt: Non-Chemical Weed Control is the first book to present an overview of plant crop protection against non-food plants using non-chemical means. Plants growing wild—particularly unwanted plants found in cultivated ground to the exclusion of the desired crop—have been treated with herbicides and chemical treatments in the past. As concern over environmental, food and consumer safety increases, research has turned to alternatives, including the use of cover crops, thermal treatments and biotechnology to reduce and eliminate unwanted plants. This book provides insight into existing and emerging alternative crop protection methods and includes lessons learned from past methodologies. As crop production resources decline while consumer concerns over safety increase, the effective control of weeds is imperative to insure the maximum possible levels of soil, sunlight and nutrients reach the crop plants. - Allows reader to identify the most appropriate solution based on their individual use or case - Provides researchers, students and growers with current concepts regarding the use of modern, environment-friendly weed control techniques - Presents methods of weed management—an important part of integrated weed management in the future - Exploits the knowledge gained from past sustainable weed management efforts

Available in PDF, EPUB and Kindle. Book excerpt: Herbicide Resistance in Weeds and Crops is a collection of papers presented at the 11th Long Ashton International Symposium in September 1989. The said symposium is held to study about the increasing incidence of herbicide-resistant weeds and the consideration of the production of herbicide-resistant crops. The book includes studies that suggest the delay and prevention of herbicide resistance; the gravity of the infestation of different herbicide-resistant weed; the management of herbicide resistance; and the mechanisms of herbicide tolerance. Also covered in the book are the improvement of different herbicides, as well as the prospective development of genetically engineered herbicide-resistant plants. Botanists, biochemists, and farmers would greatly benefit from the text, especially those who would like to explore and study the phenomenon.
