• Plant Selection and Selecting Your Plants

      Davison, Elisabeth; Begeman, John; Tipton, Jimmy; DeGomez, Tom (College of Agriculture, University of Arizona (Tucson, AZ), 2015-04)
      Whether you are beginning a new landscape or renovating an existing one, planning ahead can prevent many problems. The majority of maintenance requirements and plant problems result from either selecting the wrong kind of plant for a location or planting an inferior specimen of the selected plant type. In other words, there are two decisions to be made: ▪ What species, or kind, of tree are you going to buy — an oak, pine, mesquite, or acacia? ▪ Assuming you decide on an oak, which one in the row of oaks at the nursery are you going to buy? The first decision is called Plant Selection and the second is Selecting Plants. Our goal is to install the right plant in the right place. This publication will cover the factors involved in making good decisions to achieve this goal.
    • Pruning Deciduous Shade Trees

      Davison, Elisabeth; DeGomez, Tom (College of Agriculture, University of Arizona (Tucson, AZ), 2015-04)
      The pruning principles discussed in this publication have proven to provide the best possible out comes including tree longevity and safety. Although trees may live for years following improper pruning their life span and safety may be severely reduced. We encourage proper pruning so that the trees we care for may bring us pleasure for many years.
    • Growing Strawberries in Home Gardens

      DeGomez, Tom (College of Agriculture, University of Arizona (Tucson, AZ), 2015-06)
      Strawberries are easy to grow. They provide the first fruit of the season, and are quick to bear. When harvested fully ripe in the home garden they have excellent flavor. In stores they can be expensive and are often harvested prior to being fully ripe. Various types of strawberries are available. Each type has specific environmental requirements such as temperature and hours of daylight for good production. With the wide range of climatic zones in Arizona it is important to choose the right type of strawberry for your growing conditions.
    • Training and Pruning Newly Planted Decidous Fruit Trees

      DeGomez, Tom (College of Agriculture, University of Arizona (Tucson, AZ), 2015-06)
      Training and pruning newly-planted deciduous fruit trees is one of the most important steps in developing trees with a strong framework (scaffold branches). Trees with a good framework of branches can support heavy crops without limb breakage and will help to bring the young tree into production at an early age. Selection and arrangement of these branches determines the type of development and growth in later years. The goal of pruning and training is to balance vegetative and fruiting wood growth.
    • Pine Bark Beetles

      DeGomez, Tom; Young, Deborah (College of Agriculture, University of Arizona (Tucson, AZ), 2015-04)
      Pine bark beetles in Arizona are generally of the genus Ips or Dendroctonus. Fading foliage in the tree is often the first sign of a beetle attack. Prevention is best practiced since control is not possible once the beetles have successfully colonized the tree. Colonization is dependent upon trees being in a vulnerable condition caused by stress from various agents and site conditions.
    • Susceptibility of Mesquite Species to Powdery Mildew in Arizona

      Nischwitz, Claudia; Olsen, Mary W.; Department of Biology, Utah State University, Logan, Utah; University of Arizona, College of Agriculture and Life Sciences (College of Agriculture, University of Arizona (Tucson, AZ), 2014-12)
      Mesquite (Prosopis sp.) is a popular tree in landscapes in Arizona because of its drought tolerance and attractive growth habit. Powdery mildew has been observed from late summer until early spring on mesquite leaves. It has been identified as Pleochaeta polychaeta based on morphological descriptions and comparison to herbarium specimens. Surveys were conducted in fall 2008 through winter 2009 at two locations in southern Arizona to determine the susceptibility of different mesquite species to powdery mildew. Twelve mesquite trees representing two species were sampled at Texas Canyon near Willcox, AZ, and 177 trees representing eight species were sampled at the University of Arizona campus in Tucson, AZ. The North American mesquite species P. glandulosa var. glandulosa and P. velutina were infected with powdery mildew at the University of Arizona campus and P. velutina at the Texas Canyon site. No powdery mildew was observed on P. alba, P. cinerea, P. nigra, P. chilensis, P. pubescens and P. chilensis x flexuosa. The powdery mildew affects the aesthetic value of severely infected trees but seems to have little effect on long term tree health.
    • Cotton (Texas) Root Rot

      Olsen, Mary (College of Agriculture, University of Arizona (Tucson, AZ), 2015-02)
      The most important disease of woody dicotyledonous plants in Arizona is Phymatotrichopsis root rot (Cotton or Texas root rot) caused by a unique and widely distributed soil-borne fungus, Phymatotrichopsis omnivora. The fungus is indigenous to the alkaline, low-organic matter soils of the southwestern United States and central and northern Mexico.
    • Ten Steps to a Successful Vegetable Garden

      DeGomez, Tom; Oebker, Norman F.; Call, Robert E. (College of Agriculture, University of Arizona (Tucson, AZ), 2015-02)
      Ten carefully taken steps will produce many enjoyable moments and an abundant harvest of fresh vegetables during much of the year. The ten steps are: 1) Select a good location. 2) Plan your garden layout. 3) Grow recommended varieties. 4) Obtain good seed, plants, equipment and supplies. 5) Prepare and care for the soil properly. 6) Plant your vegetables properly. 7) Irrigate with care. 8) Mulch & cultivate to control weeds. 9) Be prepared for pests and problems. 10) Harvest at peak quality.
    • Working with Non-Profit Organizations – Cooperative Extension’s Opportunity to Expand Its Reach

Guidelines are provided for Extension personnel interested in working with non-profits.
    • Sonic Pest Repellents

      Aflitto, Nicholas; DeGomez, Tom (College of Agriculture, University of Arizona (Tucson, AZ), 2014-10)
      Commercially available sonic pest devices for use in residential applications have not been shown to be effective in scientific studies. For this reason, use of these devices is not advised to treat common pest problems. Although some researchers are developing sonic techniques that illustrate promise for very specific pests, these technologies are yet to be commercially available. As our understanding increases of how pest species receive and process sound, more relevant sonic devices may be developed. The allure of sound as a treatment for pests will remain into the future—motivated by the fact that if they are successful they will be more environmentally friendly and safer for humans.
