Trees And Shrubs

Our knowledge of the Aphididae of Africa is as yet very limited, this important group of insects having been but little studied, except in Europe and North America. At present only thirty-five species are recorded for the whole African continent, about the number one can collect in a single afternoon in one's own garden in England. It will be noticed that several common European species are recorded, and that they are as destructive in Africa as in Europe, such as the Common Cabbage Aphis (A. brassicae) and the Ribes and Lettuce Aphis (Rhopalosiphum lactucae). Several others occur which have a world-wide distribution, such as the Black Peach Aphis (Aphis persicae), and the Woolly Aphis (Eriosoma lanigerum), doubtless having been distributed on nursery stock, the former as ova and the latter as adults. Fuller has reported destroying and fumigating strawberry plants attacked by Aphis sent from Europe, and Lounsbury records the presence of Apple Aphis eggs on imported stock. Undoubtedly these insects are constantly being distributed from country to country with imported plants, trees and shrubs.

Abstract A survey was conducted to assess the attitudes of Midwestern retail nursery operators concerning current marketing, promotion, sales, and service practices of their wholesale nursery stock suppliers. Completed questionnaires were received from 290 individuals (42.2% response rate). Respondents indicated quality of plant materials (96.5%), availability of plant materials in desired quantities (67.8%), wide assortment of plant materials (53.5%), and price of nursery stock (40.3%) were very important reasons for conducting business with a wholesale supplier. The majority of respondents said they were ‘very satisfied’ with the condition of bare-root trees and shrubs (75.1%), bedding plants (72.9%), herbaceous perennials and ornamental grasses (72.2%), container-grown trees and shrubs (72.0%), and balled-and-burlapped trees and shrubs (67.4%) shipped by their wholesale supplier. Over one-half (56.5%) also said they were ‘very satisfied’ with aquatic plant shipments. On those occasions when plants arrived in unsatisfactory condition, the most frequently cited problems were, dry bare-root stock (34.4%), physically damaged container-grown stock (56.0%) and balled-and-burlapped stock (40.0%), undersized herbaceous plants (20.3%), and aquatic plants damaged in transit (12.1 %). In general, retailers were most favorably impressed with the respectful and helpful way wholesalers attempted to meet their business needs (57.1%). Retailers were most frustrated with shortages, unauthorized substitutions, and last-minute cancellations (31.9%).

Trees And Shrubs

The following herbicides were used in attempts to control weeds in lining-out stock of 16 species of trees and shrubs: simazine, neburon, endothal, CIPC, DNBP and 2, 4-D. Only simazine and neburon produced a significant reduction in weed crops. In further studies on simazine applications of 3 and 4 pounds per acre of the wettable-powder formulation provided good control. The granular formulation of simazine did not produce a significant reduction in either the number of species or crops of weeds. Variation in survival of nursery stock was more closely related to the individual species of trees and shrubs than to the formulations or rates of application of simazine.

Initial Selection

The development of a manual and database of recommended trees and shrubs was undertaken as a collaborative effort of the University of Rhode Island, University of Massachusetts Cooperative Extension and regional nursery stock producers. Initial selection was limited to species exhibiting few or no pest and disease problems, and without site requirements or other factors that could lead to higher maintenance in established landscapes. The preliminary list was reviewed by more than 30 representatives of regional arboreta, universities, growers, landscapers and arborists. In its third printing, the manual includes lists of recommended species, excluded species (with explanations), species for particular situations, and a guide to sustainable landscaping. The consortium brought together to create the manual is also developing a point-of-sale logo and poster to advertise recommended plant species and sustainable landscaping. This project has raised important issues about the interface between the industry and academia in promoting new and less readily available plants. The database is maintained in FileMaker Pro (MAC), and will be made available in several DOS or MAC formats to those supplying a unformatted3.5” DD or HD disk.

Trees And Shrubs

To guide in deciding whether artificial inoculation of container-grown woody seedlings used for reclamation purposes in Alberta might be beneficial, a survey was made of seven nurseries to determine the symbiotic status of plants ready for outplanting. Eight species of woody shrubs were rarely vesicular-arbuscular mycorrhizal if less than 1 year old and were erratically mycorrhizal after 1 to 2 years nursery residence time. Actinorhizal shrubs (Elaeagnuscommutata Bernh. ex Rydb. and Shepherdia spp.) did not become nodulated in the 1st year, and planting stock generally lacked N2-fixing ability. The mycorrhizal status of pines (Pinusbanksiana Lamb, and Pinuscontorta Dougl.) and white spruce (Piceaglauca (Moench) Voss) seedlings ranged from mycorrhizal-free to complete mycorrhization. A majority of the mycorrhizae were formed by Thelephoraterrestris Ehrh.:Fr., E-strain (Complexipes), and Myceliumradicisatrovirens Melin. Amphinemabyssoides (Fr.) J. Erikss. formed a large proportion of the mycorrhizae on white spruce, which were held in nurseries for over 1 year. A stipitate polypore, Coltricia sp., is reported as a mycorrhizal associate of nursery stock for the first time.
