This book was released on 2017-04-26 with total page 410 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book comprehensively reviews current pest management practices and explores novel integrated pest management strategies in Brassica oilseed crops. It is essential reading for pest management practitioners and researchers working on pest management in canola and other Brassica crops worldwide. Canola, mustard, camelina and crambe are the most important oilseed crops in the world. Canola is the second largest oilseed crop in the world providing 13% of the world's supply. Seeds of these species commonly contain 40% or more oil and produce meals with 35 to 40% protein. However, its production has declined significantly in recent years due to insect pest problems. The canola pest complexes are responsible for high insecticide applications on canola. Many growers rely on calendar-based spraying schedules for insecticide applications. The diamondback moth Plutella xylostella and flea beetles Phyllotreta spp. (P. cruciferae and P. striolata)cause serious damage to canola. In the Northern Great Plains, USA, for instance, P. xylostella is now recorded everywhere that canola is grown. Severe damage to canola plants can be caused by overwintering populations of flea beetles feeding on newly emerged seedlings. Cabbage seed pod weevil (Ceutorhynchus obstrictus), swede midge (Contarinia nasturtii), and tarnished plant bug (Lygus lineolaris) are also severe pests on canola. Minor pests include aphids (cabbage aphid, Brevicoryne brassicae and turnip aphid, Hyadaphis erysimi) and grasshopper, Melanoplus sanguinipes.

Available in PDF, EPUB and Kindle. Book excerpt: Canola and other oilseed Brassica species are important oilseed crops in the northern Great Plains of the U.S. and Canada. As a cool season crop, canola adds diversity to cropping rotation systems. The crucifer flea beetle, Phyllotreta cruciferae Goeze, and the striped flea beetle, Phyllotreta striolata, are the most serious insect pests of canola. Crucifer flea beetle is the dominant flea beetle pest of canola. Adult flea beetles emerge in the spring and feed on the cotyledons and true leaves. When they emerge in large numbers, they can devastate a seedling canola field quickly; therefore, timely monitoring and management of this pest is important. Control costs for flea beetles in oilseed Brassica crops often exceed $300 million annually in North America.

This book was released on 2014-12-17 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: The effect of varying seed rate and screening of insecticides were done in Kulumsa Agricultural Research Center by sowing Yellow Dodolla mustard in year 2011. The experiments were laid-out in a randomized complete block design with four replications. Two rows of 1m length were used for sampling of flea beetles and their damage. Yield was obtained from 1.5m x 2m area of each plot and expressed in kg/ha. The six seed rates revealed no significant difference in mean number of flea beetles but the mean number of damaged plants was found to be decreased from plots sown with the lowest to the highest seed rates for all phonological stages of the crop. Maximum mean seed yield (1917.8kg/ha) was obtained from plots sown with seed rate of 5.4g (10kg/ha). The higher rate of Carbaryl, Malathion and the two rates of Fenitrothion reduced significantly the mean number of flea beetles and the damage (P

Download or read book Ecorational Insecticides and Compensatory Growth Responses for Crucifer Flea Beetle Management in Canola written by Frank Boakye Antwi and published by . This book was released on 2006 with total page 169 pages. Available in PDF, EPUB and Kindle. Book excerpt: Studies were undertaken to determine the efficacy and economic potential of ecorational insecticides versus conventional insecticides as alternative management tactics for crucifer flea beetle, Phyllotreta cruciferae (Goeze). Yield to feeding injury relationships and compensatory growth responses were also determined for actual and simulated P. cruciferae feeding injury. Percent mortality, pairwise comparison analysis and LT50 values showed the efficacy to be in descending order of Helix XTra > Capture > SpinTor > BotaniGard > Neemix > Surround. LT50 values were 1 to 4 d after exposure to Helix XTra, Capture and SpinTor; and 2 to 7 d for BotaniGard, Neemix and Surround. Field studies showed that SpinTor had the best efficacy against the crucifer flea beetle among the ecorational insecticides tested. Using partial budgets analysis, the ecorational insecticides SpinTor, BotaniGard, Neemix and Surround, when substituted for the chemical insecticide Helix XTra, resulted in net losses of $29.98 to $265.84/ha. In a plant compensatory growth study, growth rate, total leaf area, plant height and yield parameters were most affected at 30 to 70% flea beetle feeding injury to seedling cotyledon canola. Seed yield and percent oil regressed on flea beetle feeding injury showed that the regression fit for yield (R2 = 0.013) and oil (R2 = 0.012) was very poor. Regression models explained 1.3 and 1.2% of the total variation in seed yield and percent oil, respectively. This indicates that crucifer flea beetle feeding injury alone was not adequate for yield prediction and that more variables are needed to improve and explain the relationship. Management of P. cruciferae should occur before 30% cotyledon injury to minimize yield losses. When plant growth responses and yield of canola were compared for simulated versus crucifer flea beetle feeding injury, simulated injury did not adequately mimic P. cruciferae feeding injury. Until an appropriate technique is found, simulated injury cannot be relied on to substitute for actual P. cruciferae feeding. Ecorational insecticides would not be economical in insecticide resistance management programs for P. cruciferae. Plant compensatory growth responses observed in this work provide valuable baseline data for refining economic thresholds to manage P. cruciferae in canola.

Available in PDF, EPUB and Kindle. Book excerpt: Crop Physiology: Case Histories of Major Crops updates the physiology of broad-acre crops with a focus on the genetic, environmental and management drivers of development, capture and efficiency in the use of radiation, water and nutrients, the formation of yield and aspects of quality. These physiological process are presented in a double context of challenges and solutions. The challenges to increase plant-based food, fodder, fiber and energy against the backdrop of population increase, climate change, dietary choices and declining public funding for research and development in agriculture are unprecedented and urgent. The proximal technological solutions to these challenges are genetic improvement and agronomy. Hence, the premise of the book is that crop physiology is most valuable when it engages meaningfully with breeding and agronomy. With contributions from 92 leading scientists from around the world, each chapter deals with a crop: maize, rice, wheat, barley, sorghum and oat; quinoa; soybean, field pea, chickpea, peanut, common bean, lentil, lupin and faba bean; sunflower and canola; potato, cassava, sugar beet and sugarcane; and cotton. A crop-based approach to crop physiology in a G x E x M context Captures the perspectives of global experts on 22 crops

This book was released on 2010-06-16 with total page 461 pages. Available in PDF, EPUB and Kindle. Book excerpt: Oilseed rape is a major arable crop in both Europe and North America. It is attacked by unique complexes of insect pests still largely controlled through the application of chemical insecticides. Crop management systems for the future must combine sustainability with environmental acceptability to satisfy both social and economic demands. This book, in its 17 chapters each led by a world expert, reviews research progress towards developing integrated pest management systems for the crop that enhance conservation biocontrol. This approach is particularly timely because of the development in Europe of insecticide resistance in the pollen beetle, a major pest of the crop. The past decade has seen considerable progress in our knowledge of the parasitoids and predators that contribute to biocontrol, of their distribution patterns, and their behavioural ecology, both within and without the crop. There is potential for natural enemy conservation through modification of within-field crop husbandry practices, as well as, on the landscape scale, through habitat manipulation to encourage vegetational diversity. This book will prove invaluable as a text for researchers, university teachers, graduate scientists, extension workers and growers involved in integrated pest management.
