Download or read book Impact of Foliar Fungicides on Yield and Net Returns in Soybeans written by Benjamin Lee Spinks and published by . This book was released on 2006 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Field studies were conducted in 2003, 2004, and 2005 in the Mississippi delta at 12 locations across common production practices to evaluate the impact of 12 single applications of fungicides at the R3 and R5 growth stage on soybean yield, seed quality, and net returns. Averaged across locations, azoxystrobin alone and mixed with other fungicides increased yields 161 to 343 kg/ha compared to the nontreated control. Fungicide applications made at R3-R4 were more efficacious and resulted in larger yield increases than applications made at R5-R6. Plots treated at the R3-R4 growth stage with 0.11kg ai/ha azoxystrobin alone or in combination with other fungicides yielded 135 kg/ha more than plots treated with the same treatments at the R5-R6 growth stage. Azoxystrobin at 0.11 kg ai/ha and azoxystrobin at 0.11 kg ai/ha + 0.035 kg ai/ha diflubenzuron were the most profitable treatments and increased net returns 23 dollars/ha and 31 dollars/ha, respectively compared to the nontreated control.

Download or read book Influence of Application Technology on Foliar Fungicide Efficacy on Cercospora Sojina Infected Soybean written by Shawn Alan Butler and published by . This book was released on 2016 with total page 86 pages. Available in PDF, EPUB and Kindle. Book excerpt: Due to the constant concern with off-target contamination and application technology requirements associated with future herbicide-tolerant crops, the use of drift-reduction nozzle technology (DRT) may increase. The primary objective of this research was to evaluate the effects of coarse droplets generated by drift-reduction nozzles on foliar fungicide efficacy and residual in soybean infected by frogeye leaf spot caused by Cercospora sojina. No differences in disease control, soybean yield, spray retention, and residual when applying Quadris Top SB, a premix of azoxystrobin and difenoconazole, using nozzles that produce either a medium or ultra coarse droplet spectrum were determined. Due to the challenge of timing fungicide applications targeting frogeye leaf spot infections, growers often make applications preventatively, prior to visual infection. Therefore, the second objective was to determine the EC50 of C. sojina isolates collected from trial locations to further investigate the residual control window of azoxystrobin. The effective concentration in which 50% of mycelial growth of resistant isolates tested were inhibited was determined to be 7.44638 [mu]g mL−1 , while the concentration for sensitive isolates was found to be 0.04789 [mu]g mL−1 . The third objective was to determine the effect of droplet size on plant coverage and canopy penetration when making fungicide applications in a commercial setting with increased potential for off-target movement. These studies showed no differences between nozzles producing either medium or ultra coarse droplet spectra when considering frogeye leaf spot control or soybean yield with an application of Quadris Top SB. Coverage analyses determined that applications made with ground self-propelled sprayers deposited 43% more solution in the upper canopy than the lower canopy, but was not effected by droplet spectra. These results indicate that DRT nozzle technology will not have a negative impact on frogeye leaf spot disease control or soybean yield when applying Quadris Top SB. Further studies should be conducted to determine the impact of DRT on other diseases of soybean or alternate crops.

Download or read book The Effect of Mid-season Foliar Fungicide and Insecticide, Applied Alone Or in Combination, on Soybean Yield in Ohio written by Sin Joe Ng and published by . 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

Download or read book Impact of Preventative Fungicide Practices on Mid-South Soybean (Glycine Max) Grain Development, Quality, and Economic Return written by Chase Alan Floyd and published by . This book was released on 2019 with total page 49 pages. Available in PDF, EPUB and Kindle. Book excerpt: The need for profitable soybean production practices gain continually with increasing input costs and reduced profit margins. Constant cultivar and product developments has resulted in limited current data available regarding the profitability of preventative fungicide applications and physiological benefits that can occur from these applications. Research was conducted during 2017 and 2018 to determine optimal fungicide application timing, while assessing multiple fungicide options and resulting effect on soybean grain yield, seed quality, and profitability. Additional research was conducted to determine optimal row spacing, planting date and fungicide application combinations to maximize soybean production profitability. These data suggest using multi-mode of action fungicide treatments increased soybean grain yield, regardless of application timing. These data also suggest, profitability from application of multimode of action fungicides can be observed at lower adjusted market prices.
