Item Smooth bromegrass(University of Missouri--Columbia. Extension Division, 2025) Kallenbach, Robert L.||Roberts, Carson"Smooth bromegrass (Bromus inermis) is a cool season, sod-forming perennial grass introduced to the United States form Hungary in 1884. It was widely adopted in the upper half of North America and has shown exceptional drought resistance and winter hardiness. Smooth bromegrass is still used today for hay, pasture, silage and erosion control purposes."--first pageItem Home fruit production : peach and nectarine culture(University of Missouri--Columbia. Extension Division, 2010) Warmund, Michele R.The peach has often been called the Queen of Fruits. Its beauty is surpassed only by its delightful flavor and texture. A tree-ripened peach is something to behold — and better to eat.Item Disease-resistant apple cultivars(University of Missouri--Columbia. Extension Division, 2010) Warmund, Michele R. WarmundDisease infection is a major limitation to growing apples in Missouri. The common diseases include apple scab, cedar apple rust and powdery mildew. With increasing concerns about pesticides, several breeders have focused on the development of apple cultivars that are resistant to the major diseases. Apple growers who don’t have the time, equipment or desire to apply fungicides may wish to plant disease-resistant varieties.Item The vertical axis system: A training method for growing apple trees(University of Missouri--Columbia. Extension Division, 2010) Warmund, Michele R.New apple cultivars often command higher prices than some older cultivars such as Jonathan, Red and Golden Delicious. If a grower can bring a new apple into production while it is in demand, a new variety can be more profitable than producing older cultivars. High-density orchard systems (greater than 500 trees per acre), such as the vertical axis system, can be used to produce fruit in the second or third year after planting. In contrast, low-density orchard systems (150 to 200 trees per acre) generally require five years to come into production. Intensive production systems such as the vertical axis system have additional benefits other than early production of fruit. Pruning and harvesting costs are reduced due to the small size of the trees. Less spray material is also applied to the dwarf trees. But there are disadvantages as well. The cost of establishment, which includes installing a trellis system, is greater. Also, more intensive management techniques are required, since disease and insect pests can spread rapidly among closely planted trees.Item Fire blight(University of Missouri--Columbia. Extension Division, 2007) Starbuck, Christopher J.; Warmund, Michele R.Fire blight is a bacterial disease affecting apple, crabapple, pear, hawthorne, pyracantha (firethorn) and related species. The bacteria commonly live over winter in cankers (old diseased areas) in the tree, from which they ooze in early spring (Figure 1). The bacteria usually are spread from the cankers by insects and by wind-blown rain. Sometimes careless pruning practices also may spread the bacteria.
