This book was released on 2017 with total page 126 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ohio soybean farmers are very concerned about disease and insect pressure during the midseason that may impact yield. The impact of mid-season management for foliar diseases and insect feeding on grain yield was studied in a series of field experiments. The first objective was to evaluate the effect of mid-season foliar fungicide and insecticide application on soybean yield, applied alone or in combination. A trial was established at 12 on-farm field site-years in Ohio during 2015 and 2016 in a randomized complete block design with four replications per treatment. Fungicide and insecticide treatments included: 1) nontreated control, 2) fungicide alone, 3) insecticide alone, 4) fungicide plus insecticide (tank-mixed), 5) fungicide and insecticide (separate tank), 6) fungicide plus crop oil, 7) insecticide plus crop oil, 8) fungicide, insecticide plus crop oil (tank-mixed). All treatments were applied at R3 growth stage (initial pod development), and data on the percent leaf area affected by foliar diseases and insect defoliation was collected. There was no significant yield response associated with insecticide application due to low insect pressure and low insect defoliation levels at the time of insecticide application at all 12 site-years. However, at the end of the growing season, the number of bean leaf beetles (2-22) and pod injury caused by their feeding (4.1-37%) were high at 4 out of 12 site-years. Fungicide application alone had significantly (P

This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Sudden death syndrome (SDS) is a soilborne disease responsible for causing significant yield reductions across soybean-producing states. Recent research indicates that infection of the soybean radicle early in the season by Fusarium virguliforme (Fv), the SDS pathogen, is critical for disease development. This suggests fungicide seed treatments could be effective in limiting early infection possibly resulting in disease control. Field, greenhouse, and laboratory studies were conducted to evaluate eight fungicides in multiple seed treatment combinations for effects on Fv infection and SDS development. Seed treatments were applied to cultivars that were moderately resistant and moderately susceptible to SDS. Field studies were conducted at two locations: in 2008, the Valmeyer, IL location was naturally infested with Fv, and in 2008 and 2009 the Urbana, IL location had a natural Fv infestation and soil was augmented with sterilized grain sorghum colonized by Fv. Similarly, the greenhouse study was inoculated with sterilized, Fv infested grain sorghum to evaluate the same seed treatments on moderately resistant and moderately susceptible cultivars. The rolled-paper towel laboratory assay tested the individual fungicides in the growth chamber using a Fv macroconidial suspension to inoculate treated seed and assess effects on seed germination, plant length, lesion size, and disease severity. Fv DNA concentrations in soybean roots were measured using quantitative polymerase chain reaction (qPCR) in early vegetative stage roots. Soybean roots from the field were collected at three timings for digital scanning and analysis with root analysis software to measure root disease symptoms. Roots were scanned and analyzed at the completion of the greenhouse trial. SDS foliar symptoms were rated several times throughout plant growth and the area under disease progress curve (AUDPC) was calculated. Harvest data were collected for the field study. In the field, seed treatments had no effect on Fv DNA concentrations in roots. Seed treatments had very little effect on roots analyzed from the field. Most seed treatments did significantly decrease SDS foliar symptoms at the Valmeyer field study compared to the control, but no differences in foliar symptoms were observed for the Urbana field studies. Yield was unaffected by seed treatments. In the greenhouse, Fv DNA concentrations were reduced by a treatment combining mefenoxam + thiophanate-methyl + azoxystrobin + B. pumilus + prothioconazole + fludioxonil compared to the non-treated control; however, the reduction in Fv DNA did not improve root growth or decrease SDS foliar symptoms compared to the non-treated control. The Fv DNA concentrations in roots did not significantly correlate to SDS foliar symptoms in the field; however, a significant positive correlation was found in the greenhouse between Fv DNA and SDS foliar symptoms. Several seed treatments decreased lesion length and disease severity compared to the non-treated inoculated control in the rolled-towel laboratory assay, but the biological seed treatment, B. pumilus, significantly decreased seed germination and plant length while increasing lesion length and SDS severity compared to the non-treated inoculated control. In conclusion, none of the seed treatments evaluated proved to have consistent effects on Fv or SDS.
Book Synopsis Impact of Early Season Insect Management Decisions on Yield of Soybean by : John Hartley North
Download or read book Impact of Early Season Insect Management Decisions on Yield of Soybean written by John Hartley North and published by . This book was released on 2019 with total page 115 pages. Available in PDF, EPUB and Kindle. Book excerpt: To determine the optimal seeding rate and utilization of seed treatment combinations for maximizing soybean yield within optimal and late planting dates. Also, experiments were conducted to quantify effects of soybean stand loss and to determine optimal seeding rates at various planting dates comparing three seed treatments. Experiments were conducted to test influence of planter type and seeding rate on soybean. Soybean seed treated with at planting insecticides showed no difference in yield compared to fungicide only treated seed. Also, yields were maximized at low seeding rates where no stand loss occurred. Soybean yields benefited from where seeding rates were increased at 20% and 40% stand loss. Higher seeding rates can provide significant risk of yield and economic losses if no stand loss occurs. Optimal plantings can significantly increase soybean yields compared to later plantings. There was a significant difference in yield where fungicide only treated seed was planted compared to seed treated with a neonicotinoid. Low seeding rates maximized yield at optimal planting dates but were penalized at late planting dates. Soybean yields benefited from increased seeding rates at the later planting dates but there was no difference in any of the seed treatments compared to untreated soybean. Also, there was less variation in inter-spacing of plants at the lower seeding rate compared to higher seeding rate when using the cone planter compared to the other planter types. There was no difference in yield for soybean planted with any of the evaluated planter types. Yield differences were observed from higher seeding rate compared to low seeding rate.

This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Nitrogen fixation by Bradyrhizobium japonicum in soybean [Glycine max] is highly beneficial in soybean crop production. Nodulation issues have been encountered on fields new to growing soybeans in recent years in Kansas. The purpose of this research was to evaluate soybean nodulation performance under various situations and seed handling practices in order to educate producers on how to achieve reliable nodulation consistency in the field. The objectives of the study were to: 1) compare inoculant products using single and double rates and in combination with one another on fields with varying soybean history; 2) determine if there was a negative interaction between inoculant products and common seed treatments; and 3) discover the influence of inoculated seed storage conditions before planting on the rhizobia's ability to successfully nodulate soybean roots. Field experiments were conducted on diverse Kansas sites in 2011 and 2012. Inoculant treatment and seed treatment interaction trials had ten and seven experimental sites respectively. Inoculated seed storage conditions were evaluated in a greenhouse experiment during the spring of 2013. All studies used a randomized complete block design with four replications. The Novozymes inoculant products generally provided superior nodulation performance over other company products in the study where soybean had not been in recent rotation with an average increase of 167% in nodule number verses the control. The combination of dry and liquid inoculant products provided a significant increase in root nodule number at five of the environments out of recent rotation with a 76% increase over single inoculant rates. Although there were early season nodulation differences between treatments in new soybean ground, these did not carry through to seed yield differences in the majority of research sites. Hot and dry summer conditions reduced yields, making detection of treatment differences difficult. There were no negative effects on nodulation performance with any of the seed treatments. Although soybean seed yield was 634 kg ha−1 greater for the Novozyme combination treatment compared to the check at one location in 2011, the control yielded as well or better than all other treatment/inoculant combinations, implying that yield differences were likely not related to inoculant treatments. At other sites, yield was not influenced by seed treatment and inoculant combinations. Results indicate that seed treatment formulations did not significantly impact bacterial inoculant product performance, soybean nodulation, or yield. Storage conditions had no effect on nodulation performance in the greenhouse study, likely due to survival of Bradyrhizobium japonicum in the heat-treated growth medium.

This book was released on 2014 with total page 290 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soybean has a strong demand for nitrogen that can be acquired from atmosphere for vegetative growth and seed production through the symbiosis with the soil bacterium Bradyrhizobium japonicum ( B. japonicum ). However, the native soil bradyrhizobia may be ineffective in nitrogen fixation and the greatest limiting factor in increasing symbiotic nitrogen fixation is the inability to influence the infection of soybean roots by a desired strain of B. japonicum due to competition from the native bradyrhizobia. Previous studies have demonstrated the efficacy of a co-inoculum seed treatment on the symbiotic competency of the soybean cultivar LS90-1920 in greenhouse and field trials. The co-inoculation by the soil bacterium Streptomyces kanamyceticus (S. kanamyceticus ) strain ATCC 12853 and strains of B. japonicum more efficient in nitrogen fixation and resistant to the antibiotics kanamycin and neomycin may have an advantage over the native bradyrhizobia regarding soybean root infection (Gregor et al., 2003). However, inconsistent inoculation responses in field trials and low efficacy in nodule competency by selected Bradyrhizobium japonicum (B. japonicum ) co-inocula were observed under greenhouse conditions. These results were attributed to insufficient population size or growth of viable co-inocula associated with the seed treatments. This recent study showed that the nodulation response of LS90-1920 to B. japonicum strains KNI-1 and KNI-3 is independent of the inoculum dose and age of the broth culture. Iron supplement to the inoculum nutrient solution significantly increased the total biomass of nodules formed by strain KNI-1 but not by strain KNI-3 on a per plant basis and had no effect on the nodule number regardless of B. japonicum strain. In the glass bead viability study, the effect of inoculum nutrient solution concentration on the viability of bacterial co-inocula is species-specific and influenced by seed coating material. The growth of Pseudomonas putida strains displayed a dependency on the concentration of the inoculum nutrient solution with graphite or vermicompost as the seed coating material treatment or with activated charcoal treatment associated with 0.1% or 1.0 % inoculum nutrient solution. The seed coating material treatments of vermicompost and graphite promote stronger growth of S. kanamyceticus strain ATCC 12853 than the activated charcoal treatment. After a six-day incubation at 28°C, a 1.0 % inoculum nutrient solution maintained the highest viable populations of co-inocula with activated charcoal and a 0.1% inoculum nutrient solution was most effective in the maintenance of the co-inocula population when graphite or vermicompost was employed as the seed coating material. By applying the appropriate level of inoculum nutrient solution, the viability of a selected B. japonicum KNI strain and co-inocula remained stable for six days in activated charcoal and graphite treatment regardless of the number of applied co-inocula. However, the vermicompost treatment did not maintain the viable populations of the B. japonicum KNI strains and P. putida strain G11-32 but support the vigorous growth of S. kanamyceticus strain ATCC 12853 and P. putida strain 17-29. Greenhouse studies employing sterilized vermiculite as a soybean growth medium showed no significant differences in nodule competency by the inoculum/seed coating treatments associated with B. japonicum strain KNI-1. However, the co-inoculum treatments significantly increased either the total nitrogenase activity (B. japonicum strain KNI-3 with S. kanamyceticus strain ATCC 12853) or the nodule number (B. japonicum strain KNI-3 with S. kanamyceticus strain ATCC 12853 and P. putida strain 17-29) versus the singular inoculum treatment of strain KNI-3. Soil-pot studies under the same greenhouse conditions showed no significant differences in the nodule competency between the inoculum treatment of B. japonicum strain KNI-3, the co-inoculum treatment of strain KNI-3 and S. kanamyceticus, and the non-inoculated control regardless of seed coating material. However, co-inoculation of emergence-promoting rhizobacteria (Pseudomonas putida strain 17-29 and G11-32) with strain KNI-3 and S. kanamyceticus strain ATCC 12853 may improve the total nitrogenase activity and specific nitrogenase activity, depending on the seed coating material and soil type. The treatment with activated charcoal employed as a seed coating material and the co-inocula of strain KNI-3, S. kanamyceticus strain ATCC 12853 and P. putida strains 17-29 or G11-32 showed significantly higher total nitrogenase activity (Stoy silt loam) and specific nitrogenase activity (Drummer silty clay loam) versus the non-inoculated control. For the Bethalto silty clay loam, the same co-inoculum treatment associated with graphite and vermicompost as the seed coating material significantly increased the total nitrogenase activity. The seed coating treatment by activated charcoal enhanced nodulation competency for both the 2010 and 2011 field trials resulting in higher grain yield, seed nitrogen content, and seed protein content versus the seed coating treatment by graphite. No significant differences by the inoculum treatments were determined.

Download or read book Recent advances in crop protection written by P.Parvatha Reddy and published by Springer Science & Business Media. This book was released on 2012-09-14 with total page 282 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the recent years, the need to increase food production to meet the demands of rapidly increasing population from a limited land resource necessitated the use of intensive farming systems, with the inputs like narrow genetic base, high dose of fertilizers, pesticides, irrigation, monocropping, etc. which led to the development of diseases and pest. The effect of changing global climate, particularly the sharp increase in CO2 concentration, has increased the susceptibility of plants to pathogens and pests. Because of the chemicalization of agriculture, the age-old eco-friendly pest management practices like sanitation, crop rotation, mixed cropping, adjustment of date of planting, fallowing, summer ploughing, green manuring, composting, etc. are not being practiced, affecting the crops adversely. This has encouraged researchers to look for eco-friendly and novel approaches for pest management. The information on recent advances in crop protection (involving bacteria, fungi, nematodes, insects, mites and weeds) is scattered. The book delves upon the most latest developments in crop protection such as avermectins, bacteriophages, biofumigation, biotechnological approaches; bio-priming of seeds; disguising the leaf surface; use of non-pathogenic strains, plant defense activators, plant growth promoting rhizobacteria, pathogenesis-related proteins, strobilurin fungicides, RNA interference, and variety of mixtures/cultivar mixtures/multilines; soil solarization; biointensive integrated pest management; among several others (fusion protein-based biopesticides, seed mat technology and environmental methods). This book is a ready reference for students, policy-makers, scientists, researchers and extension workers.
