Book Synopsis Response and Physiology of Grafted Glyphosate-resistant and Conventional Soybean (glycine Max) to Glyphosate, and Efficacy of Bicyclopyrone in Vegetables by : Yin Chen
Download or read book Response and Physiology of Grafted Glyphosate-resistant and Conventional Soybean (glycine Max) to Glyphosate, and Efficacy of Bicyclopyrone in Vegetables written by Yin Chen and published by . This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Techniques to improve specialty crop herbicide tolerance, and identifying new methods of weed control are needed to help secure the future of vegetable production. My dissertation research addressed both concerns. First, I used soybean as model plant to investigate response and physiology of grafted glyphosate-resistant (RR) and conventional (CN) soybean plants to glyphosate. Glyphosate (0.28, 0.84 and 1.68 kg ae ha-1) was applied to CN/CN (scion/rootstock), CN/RR, RR/CN (only in growth stage experiment) and RR/RR grafted plants that had been generated using CN and RR genotypes. Variables tested included three growth stages (3, 6 and 10-leaf stages), nine CN/RR genotype combinations, and two growing environments (day/night thermoperiods of 28/22 C and 24/18 C). Small CN/RR plants (65%) and medium-sized plants (50%) were injured more than large plants (40%) 34 days with 0.84 kg ae ha-1 of glyphosate. Genotype of the scion had a greater effect on glyphosate tolerance compared to rootstock. Fewer leaves produced on CN/RR construct 5388/9392 under the warmer day/night temperatures following treatment with glyphosate. Seventy-two hours after treatment (HAT), 35% less shikimate was found in CN/RR compared to CN/CN plants. No cp4-epsps mRNA was detected in leaves of CN/RR plants, but a very small amount of CP4-EPSPS protein (=0.004% of that in RR leaf) was detected in the CN/RR leaves. More foliar-applied 14C-glyphosate and derivative was translocated to the root system of CN/RR compared to CN/CN. These data indicate that translocation of glyphosate from the CN scion to the RR rootstock is a major contributor to the partial tolerance to glyphosate observed in CN/RR transgrafted soybeans. Second, to aid in development of new weed control methods for vegetables, I assessed the response of several vegetable crops as well as three important weed species to the new herbicide bicyclopyrone. Onion, carrot, radish and dill were relatively tolerant of pre-emergence (PRE) and post-directed (POSTDIR) bicyclopyrone at 37.5 and 50 g ai ha-1. In contrast, bicyclopyrone post-emergence (POST) induced severe injury. Greenhouse experiments further examined the effect of soil type and variety on the response of onion, carrot and leek to 0, 12.5, 25, 50 and 100 g ha-1 of bicyclopyrone applied PRE. All test crops were uninjured by bicyclopyrone PRE when grown in muck soil, whereas all crops grown in sand + Pro-Mix BXTM blend were injured. Control of hairy galinsoga (Galinsoga quadriradiata Cav.), common purslane (Portulaca oleracea L.) and prostrate pigweed (Amaranthus blitoides S. Wats.) treated with bicyclopyrone POST or PRE was assessed in different soils and with each weed at three stages of growth. POST bicyclopyrone at 37.5 and 50 g ha-1 controlled hairy galinsoga and small common purslane plants (¿ 80% injury).. Hairy galinsoga was well controlled (80% injury) when growing in a Wooster silt loam and in a Pro-Mix BXTM 2:3 v/v blend. Common purslane was injured by PRE application to the muck soil and was well controlled in the Wooster silt loam and Pro-Mix BXTM blend. Bicyclopyrone POST and PRE did not control prostrate pigweed in either soil type or at any growth stage.

Available in PDF, EPUB and Kindle. Book excerpt: Herbicides are the dominant technology and the most effective weed control tools ever developed that are used for the control of weeds that infest crops. Over the last several decades, in situations of intense herbicide usage, there have been many examples of the evolution of weed populations resistant to herbicides. Weed adaptations to management tactics, including biochemical mimicry in the form of evolved resistance to the herbicides used for weed control, have increased rapidly throughout agriculture and now threaten global food security. Nowadays, expended space of research activities remains to focus on the herbicide resistance to weeds and crops. The authors of Herbicide Resistance in Weeds and Crops cover various issues regarding the present relevant research.

Book Synopsis Biology and Management of Problematic Crop Weed Species by : Bhagirath Chauhan
Download or read book Biology and Management of Problematic Crop Weed Species written by Bhagirath Chauhan and published by Elsevier. This book was released on 2021-09-04 with total page 433 pages. Available in PDF, EPUB and Kindle. Book excerpt: Weeds are the main biological constraint to crop production throughout the year. Uncontrolled weeds could cause 100% yield loss. In Australia, the overall cost of weeds to Australian grain growers was estimated at AU$ 3.3 billion annually. In terms of yield losses, weeds amounted to 2.7 million tonnes of grains at a national level. In the USA, weeds cost US$ 33 billion in lost crop production annually. In India, these costs were estimated to be much higher (US$ 11 billion). These studies from different economies suggest that weeds cause substantial yield and economic loss. Biology and Management of Problematic Weed Species details the biology of key weed species, providing vital information on seed germination and production, as well as factors affecting weed growth. These species include Chenopodium album, Chloris truncata and C. virgate, Conyza bonariensis and C. canadensis, Cyperus rotundus, and many more. This information is crucial for researchers and growers to develop integrated weed management (IWM) strategies. Written by leading experts across the globe, this book is an essential read to plant biologists and ecologists, crop scientists, and students and researchers interested in weed science. Provides detailed information on the biology of different key weed species Covers weed seed germination and emergence Presents the factors affecting weed growth and seed production

Book Synopsis The Economics of Glyphosate Resistance Management in Corn and Soybean Production by : Michael Livingston
Download or read book The Economics of Glyphosate Resistance Management in Corn and Soybean Production written by Michael Livingston and published by CreateSpace. This book was released on 2015-05-21 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: Glyphosate, known by many trade names, including Roundup, is a highly effective herbicide. Widespread glyphosate use for corn and soybean has led to glyphosate resistance, which is now documented in 14 weed species affecting U.S. cropland, and recent surveys suggest that acreage with glyphosate-resistant (GR) weeds is expanding. Data from USDA's Agricultural Resource Management Survey (ARMS), along with the Benchmark Study (conducted independently by plant scientists), are used to address several issues raised by the spread of GR weeds. Choices made by growers that could help manage glyphosate resistance include using glyphosate during fewer years, combining it with one or more alternative herbicides, and, most importantly, not applying glyphosate during consecutive growing seasons. As a result, managing glyphosate resistance is more cost effective than ignoring it, and after about 2 years, the cumulative impact of the returns received is higher when managing instead of ignoring resistance.
