2004 Evaluation of Winter Wheat Variety Performance on No-Till Recrop at Moccasin and Denton
(Central Agricultural Research Center, 2004) Berg, Jim E.; Bruckner, Phil L.; Vavrovsky, Joe; Wichman, David M.; Wargo, Judee; Philips, Dave
Evaluate agronomic performance of winter wheat varieties in no-till re-crop (continuous) crop environments near Moccasin and Denton, Montana. The growing conditions for the 2004 winter wheat crop were much better than most recent years. Moisture conditions were not outstanding, but cool June temperatures minimized evaporation demand during critical seed fill. However, below average precipitation in June and July resulted in below average test weights. holding capacities. The use of broadleaf legume and oilseed crops has facilitated the use of a wider array of herbicides which has help managed wild oats, downy brome and other weeds often associated with cereal only systems. MT00159 continues to have outstanding yield performance as it has done in the two previous years. Winter wheat yields were much above expectations for both the Moccasin and Denton locations given the below average precipitation levels. The protein levels indicate some nitrogen loss may have occurred at the Denton location.
2007 Barley Variety Performance at Denton and Moccasin
(Central Agricultural Research Center, 2007) Wichman, David M.
The 2007 central Montana growing season started with plentiful moisture. Above average precipitation was received in late April and early May. However, below average precipitation and above average air temperatures received in late May through August quickly changed the yield potential of spring crops. The yield potential of later barley seedings were greatly reduced compared to the late March and early April seedings. The higher yield potential of earlier seeding dates has to be weighed against the increase potential of having winter annual weeds, particularly downy brome and Japanese brome, escape control by either tillage or glyphosate. Winter annual weed escapes in spring crops erodes part of the purpose of raising spring crops instead of winter wheat in central Montana. In some cases, late seeded barley can produce nice plump kernels with good test weights because of it lower yield potential.
The Agronomic Performance of Spring Wheat Varieties in 2007 Central Montana Trials
(Central Agricultural Research Center, 2007) Wichman, David M.
At the start of the 2007 growing season the spring wheat yield potential looked very good. Mid-late April seeding conditions were generally good. Early May precipitation was much above average. However, in late May through July precipitation levels fell below average and summer temperatures were above average. The summer growing conditions caused substantial stress to late maturing spring crops including spring wheat. Grain test weight is the primary spring wheat yield component affected by late season stress.
2008 Barley Variety Performance in Central Montana Trials
(Central Agricultural Research Center, 2008) Wichman, David M.
2008 Central Montana crop growing conditions were generally less than ideal, particularly for spring crops. Droughty conditions of late 2007 persisted through early May and commenced again in mid-June following above average precipitation in May. Frequent windy days coupled with cold dry air through most of March and early April dried and powdered the surface soil layer. The mean air temperatures for March and April were 3 and 4 degrees F, respectively, below average. Severe cold weather in late April stressed emerging seedlings and caused some seedling leaf freezing. Late April wind driven snow accumulated in undulating fashion across research nurseries resulting in variable soil moisture accumulation and variable seedling growth. A bottom line result was crop performance research results that are weak for variety selection purposes.
Bio-Priming Seed Treatment for Biological Control of Pythium Ultimum Preemergence Damping-Off in SH-2 Sweet Corn
(American Phytopathological Society, 1990) Callan, Nancy W.; Mathre, Don; Miller, James B.
Sweet corn (Zea mays) with the shZ gene for enhanced sugar content is highly susceptible to preemergence damping-off, caused primarily by Pythium ultimum in Montana’s Bìtterroot Valley. Rhizosphere bacteria that adhered to hyphae of P. ultimum and were antagonistic to the growth of this pathogen were isolated from Bitterroot Valley soils. An isolate of Pseudomonas fluorescens, AB254, provided superior seed protection from Pythium damping-off in naturally infested soils. At least 1 X 100,000,000 cfu per seed of AB254 was needed to achieve maximum protection. In a process we have termed “bio-priming,” dry seed was coated with P. fluorescens AB254 and allowed to imbibe water under warm temperatures until a 35-40% moisture content was achieved. During bio-priming, bacterial populations increased from 10 to over l0,000-fold, depending on initial inoculum level. Bio-priming provided protection against damping-off as good as or better than seed treatment with metalaxyl when the seeds were planted in cold soil. This process may be of interest and value to growers who wish to plant sweet corn or other temperature-sensitive crops into cold soils where damping-off is a problem and the use of chemical seed treatments is not desired.
2004 Evaluation of IMI Tolerant Winter Wheat Varieties and Development Lines for Yield Performance Under Continuous Cropping
(Central Agricultural Research Center, 2004) Berg, Jim E.; Bruckner, Phil L.; Wichman, David M.
This experiment was to determine the yield potential of IMI tolerant winter wheat lines in central Montana environment. However, the crop did not establish and grow well. The producer had similar experience in the surrounding field. In both cases, farm field and research plots, shallow seeding depth combined with a dry fall and spring contributed to reduced crop growth. The performance of the experimental IMI tolerant lines show that large strides are being made in improving the yield and protein content of IMI tolerant winter wheat.
2004 Intra-State Winter Wheat Variety Performance
(Central Agricultural Research Center, 2004) Berg, Jim E.; Bruckner, Phil L.; Carlson, G. R.; Eckhoff, Joyce L.; Grey, William E.; Johnston, Robert H.; Kushnak, Gregory D.; Kephart, Ken D.
This report evaluates new and existing winter wheat lines and varieties in dryland under various growing conditions in Montana and Western North Dakota. The 2004 Intrastate Winter Wheat Evaluation nursery was grown at Bozeman, Havre, Huntley, Kalispell, Moccasin, and Sidney, Montana and Williston, North Dakota. The 2004 Montana winter wheat crop varied widely across research locations due to extremes in winter survival, precipitation and growing season temperatures. The eastern portion of Montana had harsh winter conditions that caused pockets of winter kill. Severe drought conditions persisted in eastern Montana south of highway 200. Northwest Montana and north central conditions were much improved over the 2003 crop year. Cool June weather compensated for below average precipitation in central Montana. Dry conditions during grain fill reduced test weights at all locations except Bozeman. Harvest weather, in general, was good. The environmental conditions across the intra-state winter wheat locations provided for an ideal range of yields for good assessment of yield potential. These conditions provided an excellent range of yields and test weights. Grain protein levels were high. Conditions were suitable for good winter survival evaluations at Sidney and Williston.
Combined Biological and Chemical Seed Treatments for Control of Two Seedling Diseases of SH2 Sweet Corn
(American Phytopathological Society, 1995) Mathre, Don; Johnston, Robert H.; Callan, Nancy W.; Mohan, S.K.; Martin, John M.
Experiments were conducted in both the glasshouse and in the to determine if biological and chemical control agents could be used together on sweet com (Zea mays L.) seed to control Pythium ultimum damping-off or Penicillium oxalicum seedling disease. Pseudomonas aureofaciens AB254 and Pseudomonas sp. AB842 were used for control of P. ultimum and P. oxalicum, respectively. Metalaxyl seed treatment for control of P. ultimum was used at rates from 100 to 0.01% of the recommended rate either alone or in combination with P. aureofaciens AB254. Imazalil seed treatment for control of P. oxalicum was used at rates from 100 to 1% of the recommended rate either alone or in combination with Pseudomonas sp. AB842. In field tests, combining a chemical treatment with the biological agent did not affect the efficacy of disease control. Nor did combining low rates of chemical with the biocontrol agent increase the efficacy or reliability of disease control.
From Discovery to Use: Traversing the World of Commercializing Biocontrol Agents for Plant Disease Control
(American Phytopathological Society, 1999) Mathre, Don; Cook, R. J.; Callan, Nancy W.
Microorganisms play an enormously important role in plant disease control. As naturally occurring resident antagonists, they can be managed or exploited to achieve the desired results. They are responsible for the “crop rotation effect,” which is possibly still the single most important disease management tool used worldwide. On the other hand, the addition of organic materials such as compost, barnyard manure, and green manure is known to intensify the soil-sanitizing benefits of resident antagonists so much that it is sometimes possible to eliminate the need for crop rotation. Entomology is commonly used as the standard for success with biological control agents introduced into the environment. Compared case-for-case, plant pathology is a barely-visible distant second to entomology. In fact, we would have to say it is a distant third, since there are more successful cases with introduced biological control agents of weeds—herbivorous insects and pathogens—than of plant diseases. On the other hand, if we narrow the comparison to biological control with introduced micro-organisms, plant pathology begins to look quite respectable. Examples of biological control sparked the current and much more successful effort with plant-associated microorganisms as agents introduced for biological control of plant pathogens.
