. Allen's 82nd book of berries. Nurseries (Horticulture) Maryland Salisbury Catalogs; Nursery stock Maryland Salisbury Catalogs; Strawberries Maryland Salisbury Catalogs. VIRUS FREE REGISTERED Plants referred to as "virus free" in this catalog have been field grown by us from virus free foundation stock furnished by the U. S. Department of Agriculture, Bureau of Plant Industry, Soils and Agricultural Engineering, Beltsville, Maryland. Our field-grown stock has been dusted with parathion to control aphids which transmit the virus diseases. It has also been grown at considerable distances from any other strawberry plants. Since viruses do not produce clear cut symp- toms in most strawberry varieties but simply weaken and devitalize the plants, no guarantee can be made that these plants are 100% free of viruses. Because of the measures that we have used to protect these plants from virus infection, we believe them to be substantially virus free. All plants from virus free sources which meet the rigid growing requirements of our Inspection Service are entitled to be sold as "; All our virus free varieties have met these requirements and will carry a label showing that they are "; We hope W. F. Allen Company will receive your plant orders, but in any event you should get plants which meet the rigid requirements which entitle them to be registered. TRUE TO NAME We take every precaution to have all plants true to name and we will refund your money if any prove otherwise, but we will not be responsible for any sum greater than the cost of the plants ordered.
