For Spraying, Painting and Disinfecting. 



IF you grow fruit or vegetables, raise poultry or care for stock, you can't 

 get along without a spray pump. You might just as well have a good one 

 as any other kind. Get a M^ ERS — Bucket, Barrel or Power — according 

 to your needs — a guaranteed pump thai you can depend on or a fully 

 equipped outfit with lank, tiucks, etc, that ishandy to use about buildings 

 for whitewashing or disinfecting, and also adapted for sprajnng trees, 

 shrubbery, etc

Spraying Controls Peach- 

 Leaf Curl 



Oregon orchardi.st.s are given as.siir- 

 ance that correct .spraying methods 

 will control peach-leaf curl. The kind 

 of spray, time and methods of appli- 

 cation, and other important data are 

 outlined in the following paper by 

 H. P. Barss, head of the Plant Patholo- 

 gy Department of the O. A. C. Experi- 

 ment Station: 



"Peach-leaf curl is a disease which 

 undoubtedly causes thousands of dol- 

 lars of loss each year in the State of 

 Oregon. Practically all of this loss is 

 unnecessary, since this disease can be 

 satisfactoryily controlled with one 

 spraying given at the proper time of 

 year, as the experience of a great num- 

 ber of growers in all parts of the 

 state indicates. This article is written 

 for those who have failed in the past 

 to control this disease and for those 

 who will have this disease to contend 

 with as their newly-planted orchards 

 get a start. The writer is confident 

 that, barring accidents, any peach 

 grower can control this disease to his 

 own satisfaction if he follows care- 

 fully the directions set down in this 

 article. 



"Peach-leaf curl is a disease caused 

 by a fungous parasite. The infections 

 of this fungus occur early in the 

 spring just as the tender young leaf 

 points are emerging from the buds 

 and the infections are particularly bad 

 when the weather is moist and warm 

 just at this stage. Some varieties of 

 peaches are much less seriously aflfected 

 than others. When the delicate in- 

 fection threads of the fungus have 

 penetrated into the new leaves thev 



spread all through the leaf tissue and 

 the leaf becomes distorted, abnormally 

 tliickened, and of an unnatural color. 

 The whole leaf may be affected; in 

 fact, a whole twig may be affected, but 

 in other instances there may occur 

 only a few separate patches of leaf 

 surface affected by the disease. By 

 the middle of the spring the surfaces 

 of these distorted leaves become pow- 

 dery with the spores or reproductive 

 bodies of the fungus which are being 

 discharged at this time. These are 

 carried by air currents all through the 

 orchard and will eventually result in 

 the infections of the next season. After 

 discharging the spores, the leaves that 

 are alTected shrivel up and hang, dead 

 and brown, to the branches for a long 

 time. Great injury is done where a 

 large percentage of the leaves on a 

 peach tree are affected even though 

 the tree may put out a new growth of 

 leaves. The vitality of the tree and 

 the quality and yield of fruit are 

 greatly reduced. Furthermore, a tree 

 may die from the effects of the disease 

 when it sufTers two or more successive 

 severe attacks. 



"Years ago it was found that by 

 spraying the trees thoroughly with 

 bordeaux mixture -4-4-50 or with lime 

 sulphur 1-10 just before the buds began 

 to open, this disease could be con- 

 trolled. A good many .growers, how- 

 ever, wait until the last minute before 

 making the application and in a great 

 many cases find the weather conditions 

 such that spraying is impossible at that 

 time. Consequently delayed applica- 

 tion is often made very soon after the 

 buds begin to come out, but unfortu- 

 nately in such cases a great part of the 

 infection has already taken place and 



Ijractically no beneficial results come 

 from this delayed spraying. 



"It has been ff)und that while spray- 

 ing innnediately before the buds begin 

 to open does control the leaf curl, yet 

 a spray given a week or more before 

 will have exactly the same efTect. 

 Recent experiments by the Cornell 

 L'niversity Experiment Station, even, 

 indicate that spraying any time after 

 December 1 will be effective if thor- 

 oughly done. Experiments are now 

 under way at the Oregon Experiment 

 Station to determine whether or not 

 this is true under Oregon conditions 

 as well. Whatever the results of these 

 tests may be, it is the experience of 

 Oregon gi'owers that a thorou.gh appli- 

 cation given within two weeks before 

 the opening of the buds will have suc- 

 cessful results. We recommend, there- 

 fore, at the present time, that peach 

 growers spray their trees in February 

 a week or two before the buds are 

 expected to begin to come out. 



"If the presence of San Jose scale in 

 the orchard is suspected, use lime sul- 

 phur 1 to 10. If not, use bordeaux 

 mixture O-fi-.'iO. Successful control, 

 however, cannot be expected unless the 

 work is thoroughly done. Every bud 

 must be covered with the spray mate- 

 rial. This is not an easy task, but the 

 results are worth the effort. A mist 

 spray under considerable pressure will 

 generally give the best results." 



Lead Arsenates Differ 

 Lead arsenates are sold for spray 

 purposes as acid or lead hydrogen 

 arsenate and also as basic lead arse- 

 nates. These materials differ in some 

 essentials to the extent that users of 

 them in practice should be able to 

 distinguish them, says Professor H. V. 

 Tartar, who has carried out the most 

 exhaustive research work with arse- 

 nates of lead so far reported in this 

 country. Only by knowing something 

 of their identity and properties can the 

 user be able under difficult and special 

 conditions to avoid disastrous results. 

 Some of the differences are pointed out 

 as follows: The acid salt is fluffy, 

 somewhat like wheat fiour, and is 

 usually without ciystals, although un- 

 der certain conditions crystals appear. 

 The particles are of lower specific 

 gravity and settle from the water or 

 other liquid of the sprav more quickly 

 than llie basic forms. The basic form 

 is granular in appearance and has not 

 been observed to crystallize. Although 

 the size of the sei)arate particles of 

 both is practically the same, the basic 

 form particles have a tendency to col- 

 lect into groups, thus becoming heavier 

 and settling more rapidly. — O. A. C.
