It la a contagious disease f bacterial origin which, under prop er conditions, may attack any part of the tree, besides the pear and ap ple, the quince, wild crab-apple, haw tkorn, mountain ash, serviceberry ad some other pomaceous trees are subject to attacks of this disease. Ciiiiha of Die ntariifle. Klre might Is caused by a minute organism belonging to the group of bacteria and known technically as Bacillus amylovorus. It Is a rod shaped, motile germ which divides very rapidly by simple fission and Is found In Immense numbers In the diseased tissue. The germs are bo minute that they measure only about 1-25,000 of an Inch 'In length and are visible only under the highest magni fication of the compound microscope. Proofs of the Ilnoterlnl Nature of the Disease. Myriads of germs are present In all freshly blighted portions of the tree and In the stick ooze from exuding cankers. Pure cultures of the or ganism may be obtained from diseas ed tissue and cultivated for genera tion after generation on suitable cul ture medio. Healthy tissue Inoculated with germs from a pure culture will become characteristically diseased. The germs are found In abundance In the tissues so Inoculated and when, grown in pure culture and compared with germs from naturally Infected tissue, and with those used to pro duce the artificial infection, are found to be Identical. Part of the Tree Affected. The germ lives almost entirely In the sappy portion of the bark, though In some vigorous-growing varieties of pearg the germs have been known to Invade the sap wood to a limited ex tent. When Inoculated into the grow ing tips of branches, Into the blossom or the fruit, the germs are found gen erally throughout the tissues. Distribution. Fire Blight occurs in more or less severity In nearly all parts of tl.e United States where pears and apples are grown. It was first reported in the Hudson Itlver valley, N. T., about 1792 and was doubtless Indigenous In the eastern United States. The dis ease has gradually spread westward as the country became settled and ac cording to Walte became known In California about 1895-1897. Accord ing to the same author It has been known In British Columbia for almost the same period. It is probable that the dlsense has progressed westward along two rather distinct routes one north Into Idaho Washington and British Columbia, the other south In to California, In Oregon Fire Blight has appear ed In two general localities one In the southwestern part of the state, Including the Rogue River valley, the other in the northeastern part. The former region has doubtless become Infested by the spread of the disease north from California, wh le the east ern part of the state has been Infect ed through Idaho or Washington along the northern route. Life Cycle of the Dllglit Organism. Beginning In the spring the first apparent damage produced by the disease In an infected orchard is the blighting of the blossoms. Infection tlon la brought about by Insects, prin cipally bees, which have visited a case of hold-over blight and become cov ered with the organisms contained In the sticky exudation, inoculating the flowers In their search for nectar The organisms divide and multiply In the nectar and are able to enter the living tissues through the unprotected nec taries. Having entered the tissues they quickly blight the blossoms, pass down the blossom stem and into the fruit spur, killing the tissues and cutting off the leaves from water sup ply causing them to shrivel and dry, thus producing "fruit spur blight." Tho latter occurs several weeks after blossom Infection. In very serious Why Have an Overheated Kitchen in Summer?

Usually the germs die out and no not grow Into the twig or branch on which the spur occurs but occasionally the germs may continue Into the bark of the branch at the base of tho fruit spur and form a typical canker. Fruit spurs on the larger branches are a fruitful source of body Infection and many cases of blight canker originate in this way. Blight cankers may also originate through infection taking place at the tip of young actively growing branch es, particularly If these be water sprouts on the larger branches, or trunks or through Infection gaining a foothold In wounds of any kind. Such cankers on the larger limbs and trunk may retain active germs over tho dor mant season and form the so-called "hold-over" cankers which doubtless afford tho only source of Infection for the blossoms in the spring. Appearance of the Disease. The name "Fire Blight" is given to this disease because of the character istic appearance of pear foliage on twigs or branches which have been killed by the blight organisms. The leaves turn black as though scorched by fire and frequently remain on the tree during the following winter. It should be noted that this color of the foliage is characteristic of the pear when it has been killed during the growing season. If a grower not fa miliar with the pear blight desires to know how the "twig blight" looks let him girdle a twig In mid-summer and watch tho results. The foliage of the fruit spurs, killed by the blight, has much the same appearance as that of the twigs. On the apple tho foliage of twig and fruit spur blight turns brown and dry. The rankers are also quite charac teristic but arc very variable in ap pearance,, dependent on the age of the branch attacked and upon the condition of the tree. The disease progresses most rapidly In the fleshy outer layer of the bark and at first produces a watery appearance in the affected area. Later the tissues of thu bark are more or less broken down and the cankers become dark in col or and slightly sunken and are filled with a gummy substance which In ac tive canker exudes This exudate Is at first sticky and contains myriads of live germs. It Is attractive to In sects which visit such cankers In great abundance and become covered with the organisms. If after becom ing Infected in this way they visit the blossoms for nectar they Inoculate the blossom with the germs which find an easy access to the tissues of the blossom through the nectaries. Besides the hllght cankers found on the limbs and trunks one frequent ly finds In some varieties of pears and Spltzenberg apples a larger can ker at the surface on the ground ex tending up on the trunk for some distance and down the large roots. Thin condition is called "collar rot," and may result from a blight canker appearing on the trunk and running down into the collar, or may result from Infection taking place through twig blight running down water sprouts which come off at or near the surface of the ground. Wounds made by borers or gnawing animals may furnish the point of infection. A foot rot may bo caused by tho or ganisms gaining entrance to the bark of roots through infection in the tips of water sprouts which come off some distance from the tree. This condition Is common in some varieties of pears. A pear tree when badly cankered is easily recognized at a distance in the early ntitumn by the general reddish cast to the foliage. When the foliage of only a part of the tree is reddish It Indicates that a largo canker has wholly or partly girdled one of the largo branches. If the foliage of the whole tree Is equally affected we should look for a canker at the col lar or roots, it should be mentioned, She saves her strength, keeps her health and is better able to enjoy the summer.

Whetzel has pointed out that i when the apple is badly cankered, either on tho larger limbs pr trunk ' the foliage is pale green or grey, more I or less dwarfed and curled, a condr- tlon which has been called by grow ers "mouse ear." The pear and apple tree are cover ed by a protective layer of tissue, the cuticle, through which th blight or ganisms cannot enter, except the nec taries and stigmas in the blossoms and actively growing tips of branch es. Therefore except In cases of blossom Infection and some cases of twig blight the germs can enter only through wounds which expose the sappy portion of the bark. Wounds may he caused In various ways punctures of Insects, birds (sap suck ers), gnawing of animals, barking or otherwise wounding by careless farm hands In cultivation, prunnlng or pick ing. Oerms may also enter through growth cracks. Mfttlioit of Spreading the Piweaw. The Fire Blight germs are natural ly disseminated chiefly by insects at blossoming time as described above. Insects may also carry the germs to wounds on the branches or trunk. It Is probable that a portion of the in fection of the twigs resulting In twig blight may be brought about by Insect punctures. The feet of birds may be come Infected with blight germs and the disease thus carried long distances. Sap suckers may "tap" an active canker and carry the germs to unin fected trees. Typical cases of body blight have been traced by Walte to this sort of Infection. Rain may wash the germs from the ooze of active cank ers to wounds, Insect punctures or growth cracks lower down on the branches or trunk of the same tree. One of the most fruitful sources of Infection has been by the pruning shears or -saw. In pruning, if an ac tive canker Is cut Into, the tools be come infected and serve as Inoculat ing Instruments to spread the disease throughout the orchard. Infection may spread very rapidly from one district to another along highways where seedling apples and pears are allowed to grow unmolest ed. Seedling trees springing from fruit cores thrown from car windows mnke of the great overland railroads a natural and easy road over which Fire Rlight may travel for long dis tances through unsettled regions.

Method of Control. The only known method of con trolling Fire Plight is to cut out all caes of hold-over cankers wherever they appear.- Spraying with fungi cides Is of only supplementary value and the various "blight cures" are worse than useless and It Is a waste of time and money to apply them. Experience has shown that It Is of little permanent value to attempt to cut out the fruit spur and twig blight as they appear. Unless these forms of the disease extend into the branch es on which they occur and a canker Is formed the disease usually becomes naturally limited and the germs grad ually die, due to drying out of the canker so that at the beginning of the dormant season very few such cases show live germs present. The efforts of the grower should he directed to cutting out all cases of blight canker and body canker dur ing tho fall, winter and early spring when the cankers have become more or less limited in their growth and are not actively spreading. Slimmer culling Intelligently ap plied Is frequently of great value par ticularly whore there is only a little blight. In the autumn before the leaves fall Is a good time to do tho cutting as all cases of twig blight are easily ohserved and the condition of, the foliage as already described, of fers a convenient method of determin ing the presence of cases of root rot or collar rot and obscure cases of blight canker on body or lower limbs. Every orchardlst In an infected dis trict should examine all pear and ap ple trees at the time suggested and cut out all diseased portions. The trees should be particularly examined for cases of the collar rot. It Is this form of the disease that causes many trees to bo killed outright. In infected regions It has been found practical by tho most success ful owners of commercial orchards to keep one or more men in the orchard during the summer nnd fall whose sole duty it is to locate and cut out all cases of blight canker as soon as they appear. This work of Inspection and eradication can very profitably be carried on during the summer and early autumn but the best time to do Hay's fjz?Jg!

RECUSE ALL MJBSTITUTES PKNm.KTON DRTJO COMPANY. fm the work is In the late fall, winter and early spring, for reasons already g'ven. If an orchard Is gone over carefully by trained inspectors two or three times nnd all cases of this so. called "holdover" blight he cut I hero will be no source of infection in the spring and consequently no blos som blight. A final and very thorough inspec tion of orchards should be made In the early spring before the blossoms open so as to detect and remove aiy cankers which may have been missed In the earlier inspections. This is one f the most important Inspections that should be given. The matter of eradication Is com plicated, however, by the fact that Insects may carry the disease con siderable distances, and even though one grower may eliminate hold-over blight from his own orchard he may lose a large part of his crop by blos som blight and have his orchard re- infested by Insects carrying the blight germs from hold-over cankers In a less careful neighbor's orchard. Ap ple and pear trees In town and city lots are seldom cared for In an up todati; manner and In Infected fruit districts become a very serious men ace to commercial orchards In the vi cinity. Huh to Cut Out Ilk; Disease. Where cankers occur on small limbs or are so extenslxe as to nearly girdle the limbs on which they occur the wholL. limb or branch should be removed. In cutting off such a limb it is important that one get well be low the area of Infection. For safety, the cut should be made at least a foot below apparent infection s'nee in actively growing cankers the dis coloration of the bark is frequently so slight as to beeasily overlooked. Where cankers occur on the larger limbs and trunks, if not too extensive, the limb or tree may frequently be saved by carefully shaving off the dis eased bark of the cankers to the cap wood. Here again one should cut well beyond the point of infection, espe cially above and below the canker since the germs spread most rapidly up and down from the point of infec tion. In the pear at the beginning of the dormant period the diseased bark or hold-over cankers has a characteristic reddish tinge and with a little experi ence one can tell how far Infection has occurred. ' In actively growing cankers in spring and summer It Is frequently very difficult to determine the extent of the Infection vertically as there may be very little discolora tion. Ill Prp'vS it is usually more difficult to determine the extent oft Infection than In pears. ( In cuttine into the cankers it is ,.nvf.nient to U)!e a gouge such as is used by carpenters. This Is especially valuable where cankers occur in crotches of limbs. It has the special advantage of making a clean cut that cm be easily sterilized. Sanitary Measures. In cutting out the cankers it is ne cessary that the tools be kept moist rtlo'nfBOf.-int tf this is not done when cutting out an ac tive canker each cut will reinocuiate the germs into the bark at the edges of the canker and the labor may thus be useless. Corrosive sublimate in a solution of one part to one thousand of wa ter lias been found to be the most satisfactory disinfectant. It is .con venient to buy this from the drug gist in tablet form The solution is a violent poison and should be so marked and carefully guarded. It should be kept in a glass bottle as It will corrode metal containers. It is convenient to carry a sponge or cloth which is kept moist with the disinfectant and used to wipe off the tools after each cut. After the pro cess of cutting out a canker Is com pleted sufficient time should be al lowed for the canker to dry out thoroughly when the surface should be caiefullv disinfected, and then painted over with white lead paint. The wound should be kept painted with a coat of paint till healed over by the formation of callus. When cutting out twig blight or when pruning out badly diseased limbs the same precaution should be taken nnd the pruning tools sterilized after each cut. All pruned branches should be immediately taken from the orchard' and burned. This Is espe cially important If cutting Is done in summer. In Infested districts sterilization of all tools after each cut during reg ular summer or winter pruning should be made a regular practice since it might happen that a hold-over cank er be cut into and the tools become infected and the disease thus spread throughout an orchard. Supplementary Methods of Control. Spraying with lime-sulphur solu tion winter strength after the final spring inspection and Just before the buds open has been suggested by Waite as an aid In preventing the spread of Fire Blight. An applica tion at that time would cover over any cases of holdover canker and serve to disinfect the sticky ooze as well as render It less attractive to In sects. Waite's method of pruning the pear in vase form makes the best type of tree in which to fight the pear bl'ght. Fruit spurs should be kept off the larger branches and under no condition should water sprouts be al lowed to form on the trunk or from the roots. These when occurring on branches or trunks should be cut off flush with the wood. A convenient tool for this purpose is the carpenter's gouge. Should w-ater sprouts spring up from the roots they should be cut j off below the ground. i It is a good practice In Infested dis- i tricts to remove all "weed" trees of the Pome family which occur along I roadsides or in the vicinity of com- mercial orchards as such trees are veritable nurseries for the blight Practicability of Controlling lire Rllglit. Fire Blight has proven so wide spread and destructive and has ruin ed so many pear and apple orchards in various sections of the country that many persons have the erroneous Idea that It can not profitably be controll ed. In recent years It has been prov en conclusively that where all the pear and apple grfowers In an Infected district work together, the control of Fir? Hllght Is not only practicable but ceases to be a serious problem. The difficulty comes in getting ail the growers to Inspect their orchards and cut out the disease faithfully each year. There are always disinterested persons, and in Oregon at least, there are still some general farmers scat tered through the fruit districts who own family orchards. It is difficult to make such men realize their re sponsibility In regard to Fire Blight. The town and city lot orchardist Is in the same class. Efficient county fruit Inspection can do a great deal toward persuading, and If necessary forcing, such persons to either keep the dis ease under control ln their orchards or cut down the Infested trees. Pub lic sentiment must be aroused before the county fruit inspector can do ef ficient work. The greatest good comes In educating the people con cerned, first to a relalzation of the danger of Fire Blight and then to the methods by which the disease may be kept under control. This work has been under the immediate direction of P. J. O'Bara, assistant pathologist In the department of agriculture. Through a system of county fruit in spection coupled with efficient edu cation in regard to Fire Blight, pub lic sentiment has been aroused and the people work together In controll ing the disease. It should be emphasized however, that the Fire Blight Is a state and not a local problem. The disease is spreading and In time will without doubt occur in all parts of the state. It depends on the people whether or not it will be held under control. Complete eradication is not to be ex pected. Note It is proposed to Issue from time to time circular bulletins dealing with crop pest problems. This cir cular Is the first of the series.
