Preventative Control Of Brown Patch With Select Fungicides, E. Alderman, J. Reeves, J. Hoyle
Preventative Control Of Brown Patch With Select Fungicides, E. Alderman, J. Reeves, J. Hoyle
Kansas Agricultural Experiment Station Research Reports
Preventative applications of Velista and Heritage Action fungicides will decrease the percentage of brown patch observed in a perennial stand of tall fescue.
Sudden Death Syndrome And Soybean Planting Date, Eric Adee, C. R. Little, I. A. Ciampitti
Sudden Death Syndrome And Soybean Planting Date, Eric Adee, C. R. Little, I. A. Ciampitti
Kansas Agricultural Experiment Station Research Reports
The effect of soybean planting date on the severity of sudden death syndrome (SDS) and yield were evaluated in two studies at the Kansas River Valley Experiment Field in 2015. One study was established to promote SDS and the other to minimize SDS. In both studies the severity of SDS was greatest with the earlier planting dates, except for the more tolerant variety. The yield was greatest with the earlier planting date, except for the most susceptible variety. The severity of SDS was not as great as had been observed in previous years.
Timing Of Strobilurin Fungicide For Control Of Top Dieback In Corn, Eric Adee, Stu Duncan
Timing Of Strobilurin Fungicide For Control Of Top Dieback In Corn, Eric Adee, Stu Duncan
Kansas Agricultural Experiment Station Research Reports
Significant yield losses can result from top dieback (TDB) in dent corn (Zea mays), which is caused by infection by the fungus causing anthracnose (Colletotrichum graminicola). Research is limited on the effectiveness of fungicide application because of the unpredictable nature of the disease. Two field studies were established to assess the timing of fungicide application on TDB, one in Illinois (2010) and the other in Kansas (2015). Fungicide applications at tasseling (VT) and later were effective in reducing the incidence of TDB 20 to 30% and increasing yield 15 to 19 bu/a, or up to 10%, …
Development Of Cold Hardy, Large Patch Resistant Zoysiagrass Cultivars For The Transition Zone, Mingying Xiang, J. Fry, M. Kennelly
Development Of Cold Hardy, Large Patch Resistant Zoysiagrass Cultivars For The Transition Zone, Mingying Xiang, J. Fry, M. Kennelly
Kansas Agricultural Experiment Station Research Reports
TAES 5645, a Z. japonica genotype that exhibited resistance to large patch in preliminary studies, was used as a breeding parent and crossed with 22 cold hardy zoysiagrasses, resulting in 985 progeny. These progeny were evaluated for cold hardiness and agronomic traits (establishment rate, overall quality, spring greenup, leaf texture, and genetic color) in Manhattan, KS; West Lafayette, IN; and Dallas, TX; from 2012 to 2014. From this work, 60 progeny were identified for further evaluation in larger plots. During the 2015-2016 establishment year, experimental line 6102-47 showed good vigor and spring green up rate, which is comparable to ‘Meyer,’ …
Interaction Between Seed Treatment And Variety On Sudden Death Syndrome Symptoms And Soybean Yield, Eric Adee
Interaction Between Seed Treatment And Variety On Sudden Death Syndrome Symptoms And Soybean Yield, Eric Adee
Kansas Agricultural Experiment Station Research Reports
Sudden Death Syndrome (SDS) is a soybean disease that perennially limits yields in the Kansas River Valley (KRV). The presence of soybean cyst nematode (SCN) and saturated soils has been implicated in contributing to the severity of the disease. Selecting varieties with some degree of tolerance to SDS has been the primary cultural practice to reduce yield loss to SDS. Another tool to reduce yield loss to SDS has been made available to growers with the release of ILeVO seed treatment from Bayer CropScience (Research Triangle Park, NC). The potential benefit of ILeVO on varieties with different levels of tolerance …
