WALTON, President In the selection of crops, shade trees, ornamental shrubs, or other plants to be grown in root-rot areas, it is of great importance to know the relative susceptibility or resistance of plants to the disease. This bulletin furnishes such information for 2,116 species or subspecies of plants belonging to 131 families. Only 408 of these species, about 19 per cent, are immune to the disease. Resistant species number 403. The remaining 1305 species are moderately to extremely susceptible. All grasses and related plants (Monocotyledonea-e) listed are immune to root rot. Most of the Dicotyledoneae, including such plants as elm trees, cotton, alfalfa, and sunflowers, are suscepti- ble, although many plants in certain families, such as mints, crucifers, and cucurbits, are resistant or immune. All the Gymno- spermae, such as conifers, listed are resistant or susceptible; none are immune. Each plant is listed with its technical name, common name, and root-rot rating. In the main list, the plants are arranged alphabetically by the technical names under each family. Tech- nical and common names are combined in a single alphabetic index, to facilitate reference.

J. Taubenhaus, Chief, and Walter N. Ezekiel, Plant Pathologist and Laboratory Technician, Division of Plant Pathology and Physiology. The root-rot disease, caused by the fungus Phyntatotrichum omnworum EShear) Duggar, attacks plants growing in favorable soils throughout a {egion extending from the Gulf of Mexico to southern California, and tram Utah south into Mexico. In Texas and elsewhere in this region, foot rot is the most destructive plant disease. _In the study of root rot at the Texas Agricultural Experiment Station, pinch information as to the relative susceptibility or resistance of plants fpplthis disease has been obtained. Many plants are highly susceptible to rot; other plants are somewhat less susceptible and may survive for ‘ifipfew years even in the presence of the disease; while some plants are highly resistant or immune. The relative susceptibility of some of these plants has been given in‘ previous publications (2, 18, 21, 22). The present bulletin has been prepared in answer to requests from farmers, turserymen, county agents, teachers, home owners, and oflicials con- lected with the Forest Shelterbelt and Soil Erosion projects, as well as zesearch workers, for a new list to include the information now availa- iie. The present list gives root-rot ratings for more than a thousand plants not previously listed. Methods of study: This bulletin includes information secured in two Lifierent ways. Some of the plants mentioned have been grown in experi- mental fields and artificially inoculated with root rot. Plants that have gained free of the disease after repeated inoculation are known to be stant. For the rest of the plants mentioned in the list, the root-rot tings given are based on field observations. For many years, plants und in root-rot areas throughout the State have been examined to find nether they have been infected naturally by the disease. Infected roots i‘; e always examined with the hand lens or microscope to determine “e presence of the typical Phymatotrichum strands. Plants that mained apparently normal, under the same conditions, were pulled =1 also, and if the roots proved sound and free from strands were nsidered resistant or even immune. Obviously, root-rot ratings based '1 this second method of study are not necessarily final. Plants listed susceptible may safely be considered susceptible to the disease, but the plants listed now as resistant, some may later be found to be A ceptible to root rot. Plants included the list: The list includes crop plants widely grown root-rot areas; native weeds, shrubs, and trees; and also some less 6 BULLETIN NO. 527, TEXAS AGRICULTURAL EXPERIMENT STATION common plants. Some of the last group are nursery introductions o1 rare weeds, which may not be suited to the soil or climatic condition: where root rot is prevalent, but are listed on the basis of their observer‘ reaction to the disease. The general arrangement of plants in the main list (Table 2) is alpha- betically by technical names of the plants in each family. The order o1 families is approximately that of Engler and Prantl as used by Seymoul (14). Names of plants have been given in general by the Internationai Code, and agree usually with the names preferred by Gray's Manual (12), Bailey’s Hortus (3), and Rehder (11). In many cases the names used by Small (15, 16) have been added as synonyms. Common names have been taken from the works of these writers and also from Stand- ardized Plant Names (1). Additional authorities consulted have been Wooton and Standley (23), Hitchcock (8), Mattoon and Webster (10), and Schulz (13). The writers are indebted for identification of plants to the late Dr. L. H. Pammel, the late Professor H. Ness, Mr. V. L. Cory, and curators of the Philadelphia Museum of Natural Sciences and the United States National Museum; to Mr. D. T. Killough for assistance in the collection of some of the plants; and to Mr. H. B. Parks, Mr. S. E. Wolff, and Dr. R. G. Reeves for criticism of the manuscript. Root-rot ratings: The general basis for the root-rot ratings given in the list is the percentage of plants which develop visible symptoms of the disease when exposed to root-rot infection under favorable conditions. This rating expresses what actually happens in the field when conditions are favorable for root rot. Yet even extremely susceptible annual plants, such as cotton and okra, are planted year after year in root-rot areas, and yield a partial crop even during years in which the disease is widely prevalent. This is true because the root-rot fungus is not uniformly dis- tributed in the soil throughout infested fields, but instead overwinters on the surviving roots of plants previously infected or as sclerotia, located only at irregular intervals in the field. The disease appears first on the scattered plants of the new crop that grow closest to these centers of infection. Root rot then spreads, at a rate determined by weather con- ditions, to plants adjoining those first infected. Crop loss is greatest with plants killed early in the season, and least with plants that are attacked later (5). Since weather conditions do not necessarily favor spread of root rot every year, very susceptible annual crops may be grown, although‘ with a varying amount of loss, even in areas where the disease is very prevalent. This consideration does not apply to long-lived plants such as shrubs and trees. Thus, susceptible fruit trees, even if they acciQ dentally escape root rot for several years, are likely to be killed beforej any fruit is produced. I i The relative susceptibility of plants is indicated in the list by symbolsz; “——” for immune plants; “+” for resistant plants; “++” for moderately} susceptible plants; “+++” for highly susceptible plants; and “++++"§_ i 5 i RATING OF PLANT$ WITH REFERENCE TO RELATIVE RESISTANCE 7 for extremely susceptible ‘plants. More detailed definition below will em- phasize the need of interpreting these symbols differently for annual and perennial plants. Immunity, as shown by “—”, indicates that no evidence has been found of root-rot infection on these plants, even when grown in root-rot areas under favorable conditions. Some of these plants may not be com- pletely immune, but this can be determined only by further observation or by artificial inoculation experiments. . Resistant plants, designated by “+”, include “passive hosts” or “passive carriers.” The fungus infects the roots of such plants but the host develops new roots and survives in spite of the disease. Small percent- ages of resistant plants, usually less than 5 per cent of annual plants, may die from the disease. With perennial plants of this group, such as live oak and pomegranate, the seedlings or newly-rooted cuttings are somewhat susceptible, a small percentage succumbing to root rot, while older plants appear almost immune and mature plants very rarely suc- cumb. A good stand of perennial plants of this group may be expected to survive to maturity. Moderately susceptible plants, designated by “++”, usually survive long enough to be used to a certain extent in plantings in root-rot areas. Annual plants included in this “group are rated directly as those of which approximately 5 to 30 per cent may die of root rot during the one year of life; perennials included are those of which approximately 10 to 30 per cent of the plants that have survived past the seedling stage may succumb during any one year of their remaining life. Typical perennial plants of this group are many of the pines, which are quite susceptible in the seedling stage, a half or more succumbing at this time. The older plants are less susceptible and do not die rapidly from root rot, yet some of them succumb from year to year so that eventually only about one-tenth two-tenths of those that survive the seedling stage may reach maturity. ifhe continued loss in this way of trees of this group may make them ‘Aindesirable in root-rot areas even though these plants succumb to the fflisease rather slowly. e Highly susceptible plants, designated by “+-|-+”, include annuals and erennials of which approximately 30 to 8O per cent of plants exposed root rot will die during the year. Old as well as young plants in this roup are susceptible to root rot. Trees in this group rarely survive for any years when exposed to the disease. Extremely susceptible plants, designated by “++++”, include annuals of which 80 to 100 per cent will succumb rapidly to the disease during the Yyear, and perennials of which 60 to 100 per cent may succumb during any one year. ‘s i i E l‘ 8 BULLETIN NO. 527, TEXAS AGRICULTURAL EXPERIMENT STATION These ratings are summarized in tabular form below: Perennial plants Annual plants. Ratings Percentage suc- Loss during any Total percentage cumbing to root Loss during ' succeeding year likely to succuml rot during the year seedling stage after seedling stage before maturity — 0 None 0 0 _ + 0-5% Slight 0-2% 040% ++ 5-30% Considerable 10-30% S0-90% 30-80% Heavy \ 30-80% 90-100% + 80-100% Heavy _60-100% - 100% It should be pointed out that the symbols used in the present list d not have the same meaning as symbols used in various earlier root-r: lists. Therefore the ratings given in previous lists should not be con pared. with those given here unless note is made of the differences in dei nition of symbols in the various publications. Some ratings in earlie lists have been changed in the present list to agree with our preset information.1 Discussion: It has already been pointed out (18, 19, 9) that root rc is indigenous on native plants throughout the root-rot area. A wid range of native plants, listed with “+” and “++" ratings, are somewhz susceptible to the disease and act as “passive carriers.” Such plants ma survive for some time after portions of their root systems are infectei thus insuring survival of Phymatotrichum omnivorum on the roots. Unde such ‘conditions, the disease is usually not noticed. When the land 1 planted to a susceptible crop, however, root rot starts from the survivin roots of the native vegetation and spreads rapidly along the more susce] tible roots of the crop plants. In cultivated fields, weeds may continue t play an important part in aiding survival of the fungus during fallo‘ periods. The fungus may overwinter on roots of weeds that grow throug the winter, and spread from these roots to roots of succeeding susceptibl crops (17). A summary of the entire list by families, to show difierences in th relative susceptibility of large groups of plants to root rot, is given i.‘ Table 1. For each of the 131 families, this summary gives the numbe of species that have been assigned root-rot ratings indicating the variou degrees of susceptibility or resistance. The outstanding feature of the, list is the immunity of the monocotyledo nous plants to the disease. This was confirmed experimentally by repeatel and extensive inoculation of a variety of monocotyledonous plants (201 which nevertheless remained free of any symptoms of the disease. Th4 1In the present and in previous lists, watermelon has been considerel resistant to root rot. In Texas, watermelons are not grown commercially i1 root-rot areas, and the disease very rarely attacks watermelons grown i1 home garden plantings in such areas. Butler (4) has reported the disease a attacking four varieties of watermelons ‘grown in Arizona. ’ RATING OF PLANTS WITH REFERENCE TO RELATIVE RESISTANCE 9 munity of Monocotyledoneae appears to be due to the presence in ts of these plants of a relatively high concentration of some substance t inhibits growth of the root-rot fungus (6, 7). Within the susceptible dicotyledonous ‘group, there are interesting iations in the reactions of families." Most of the Cruciferae are im- une or highly resistant. Other families, such as Malvaceae and Euphor- ’ ceae, are quite generally susceptible. In other families, appear all ges between extreme susceptibility and almost complete immunity. In e Leguminosae, for instance, the black locust is very" susceptible, while e} retama (Parkinsonia aculeata) is resistant or immune. Similarly, the Moraceae the fig is extremely susceptible, while the Osage orange highly resistant. f the Gymnospermae listed, not one is immune to root-rot. Most of - gymnosperms, such as pines, firs, and larches, are at least moderately eptible. A few cedars and arborvitaes are relatively resistant. ‘ hesentire list includes 2,116 plants. Of these, only 408, or about 19 _ cent, are immune to the disease. Plants susceptible (excluding only e immune) number 1708, or about 81 per cent. Dividing the list in ther way, the three more susceptible groups, of moderately to ex- ely susceptible plants, include 1305 plants or about 62 per cent of total. That is, about one-fifth of the plants listed are immune to root another fifth are resistant, and the remaining three-fifths are = nitely susceptible. 10 TABLE 1.

Technical names of genera given in the list as synonyms are here indexed in italics, as in Common names are given usually only once, under (the most important word. For example, “Tar weed” is indexed as “Tar weed,” and “Silvery croton” as “Croton, silvery.” - Root-rot ratings have been inserted in this index following the com- mon names of plants, so that the ratings of plants with recognized com- mon names may be found easily. Where several different plants with the same common name have different root-rot ratings, the ratings have been omitted from the index.
