Fungicide Sensitivity Screening Of Corynespora Cassiicola In Us Soybean And Cotton, Tyler Miles Smith
Fungicide Sensitivity Screening Of Corynespora Cassiicola In Us Soybean And Cotton, Tyler Miles Smith
Doctoral Dissertations
Target spot, caused by the fungus Corynespora cassiicola, is a foliar disease of cotton and soybean. Target spot has become a disease of concern in soybean and cotton production systems. Data for fungicide sensitivity and understanding potential impact on yield is lacking for C. cassiicola. Fungicide resistance is also a concern in C. cassiicola with the increase in resistant pathogens in soybean. With the lack of knowledge about baseline fungicide sensitivity and the concern of fungicide resistance the objectives of this study were: (i) to evaluate fungicide products and mixes in small plot soybean and cotton trials, (ii) …
Evaluation Of Corn Agronomic Management Practices Following A Rye Cover Crop, Daniel John Quinn
Evaluation Of Corn Agronomic Management Practices Following A Rye Cover Crop, Daniel John Quinn
Theses and Dissertations--Plant and Soil Sciences
Fall implementation of a rye (Secale cereale L.) cover crop (RCC) prior to spring corn (Zea mays L.) planting is a management practice used to improve soil conservation, water quality, and limit herbicide dependence. However, corn growth and yield following a RCC is often reduced due to early-season nitrogen (N) stress and decreased plant emergence, which can limit RCC adoption. The objective(s) of this research were to evaluate corn agronomic management practices (e.g., N and seeding rate management, in-furrow (IF) starter use) following a RCC and determine which management practices can be used to limit corn stress following …
Winter Wheat Response To Different Fungicide Management (Products And Timing Of Application) During The 2019-2020 Growing Season, G. Cruppe, B. R. Jaenisch, R. P. Lollato
Winter Wheat Response To Different Fungicide Management (Products And Timing Of Application) During The 2019-2020 Growing Season, G. Cruppe, B. R. Jaenisch, R. P. Lollato
Kansas Agricultural Experiment Station Research Reports
Foliar fungicides can improve wheat grain yield in Kansas, but there is limited information on the efficacy of different products as well as the timing of application. We conducted a field study in five Kansas locations to evaluate the yield, test weight, and protein responses of WB-Grainfield to different commercial fungicides applied at different times during the growing season. The trial was conducted in a randomized complete block design to evaluate (1) a non-treated control; Topguard applied at 5 ounces per acre at (2) jointing, (3) heading, and (4) jointing plus heading; (5) Delaro applied at 6 oz/a at jointing; …
Winter Wheat Variety Response To Flag Leaf Foliar Fungicide Application In 2019–2020, G. Cruppe, B. R. Jaenisch, R. P. Lollato
Winter Wheat Variety Response To Flag Leaf Foliar Fungicide Application In 2019–2020, G. Cruppe, B. R. Jaenisch, R. P. Lollato
Kansas Agricultural Experiment Station Research Reports
Foliar fungicide can be an important tool in improving wheat yields, but its effectiveness is season- and variety-dependent. To evaluate the yield, test weight, and protein responses of different commercial winter wheat varieties to one foliar fungicide application around heading, we conducted a trial combining four winter wheat varieties and two fungicide management treatments in Manhattan during 2019–2020. The control treatment consisted of no fungicide application, and the alternative treatment consisted of 5 oz/a Absolute Maxx + NIS applied at heading. Varieties evaluated were Bob Dole, Larry, WB4269, and Zenda. The study was conducted under no-tillage practices following a previous …

Impact Of Fungicide On Wheat, G. F. Sassenrath, H. Zhao, X. Lin
Kansas Agricultural Experiment Station Research Reports
This is a report of research to test the impact of fungicide and management on wheat yield and quality. Fusarium head blight (FHB), or scab, is a persistent problem in wheat production, especially in high rainfall areas such as eastern Kansas. Two cultivars of winter wheat varying in FHB sensitivity (Everest, moderately resistant, and KanMark, susceptible) were tested for control of FHB using fungicide treatments made to the seed prior to planting or to the wheat plant at heading, in tilled or no-tilled management. The wet spring of 2020 resulted in high FHB pressure, but dry conditions at harvest reduced …
