INJURY FROM 



FRUIT TREE 

 PESTS 



ETERNAL vigilance, and the 

 prompt application of the 

 most reliable and effective 

 spraying materials is neces- 

 sary to insure a profitable crop. 



Some people may be able 

 to afford gambling on some 

 things, but mighty few fruit 

 growers are willing to risk a 

 crop failure by taking chances 

 on spraying materials. 



Our appeal is to the thought- 

 ful fruit grower who fights shy 

 of unsupported claims, and 

 demands to be shown. It is to 

 him, who, if he were raising 

 live stock would own full 

 blooded sires; or if corn, would 

 see to it that the seed was 

 perfect. 



To such fruit growers we 

 offer Orchard Brand Dry 

 Powdered Arsenate of Lead 

 as a crop and tree protection. 

 It has been proved effective. 

 Its results are known. We 

 shall be glad to give you the 

 names of many successful 

 fruit growers who are enthu- 

 siastic about its results. 



Suggestion; Write for the booklet.

 Dormant Spraying of Deciduous Fruit

Other spray materials, for specific 

 purposes, we recommend are:

Timely Topics and Advice for Fruitgrowers 



As the spraying season is at hand it will 

 be well to beware of the man who olTers to 

 spray your fruit trees for a few cents a tree. 

 According to reports made on this question 

 by various experts who have conducted experi- 

 ments to determine the cost of spraying or- 

 chards it costs from 50 to 60 cents per tree to 

 spray trees that have reached an age of 1.5 

 to 18 years with four sprays. Therefore it 

 will be the part of wisdom to avoid the man 

 who offers to spray your orchard at a very 

 cheap figure. 



If you are contemplating buying nursery 

 stock do not go into the deal with your eyes 

 closed. Patronize only reliable dealers and 

 insist that the stock shall be entirely free 

 from disease and in perfect condition. In 

 disregarding this advice you are liable to intro- 

 duce into your new orchard or berry patch 

 troubles that it will take years to overcome. 



In writing of the comparative merits of cal- 

 cium arsenate and arsenate of lead, W. S. 

 Regan of the Massachusetts Experiment Sta- 

 tion at Amherst, says: "The killing einciency 

 for the powdered forms of arsenate of lead and 

 calcium arsenate, pound for puond, is about 

 equal, the former containing about 33 per cent 

 of arsenic and the latter about 43 per cent. 

 Based on an equal arsenical content for a 

 given amount of spray solution, there is a 

 slight advantage in killing power in favor of 

 arsenate of lead. Arsenate of lead is the best 

 poison to use alone. Calcium arsenate cannot 

 be used safely alone upon foliage, but must 

 be combined with milk of lime or a fungicide, 

 such as lime sulphur or bordeaux mixture. If 

 combined with milk of lime its cost is in- 

 creased so that it is practically equal to that 

 of arsenate of lead, thus giving the latter the 

 preference because of superior killing power. 

 Arsenate of calcium is the only arsenical which 

 can be safely combined with lime sulphur or 

 other sulphid sprays, and this combination is 

 the logical orchard arsenical fungicide. Ar- 

 senate of lead seems to work slightly better 

 with bordeaux mixture, but calcium arsenate 

 is probably cheaper, so that the question of 

 which to choose for use with this fungicide is 

 mainly a matter of convenience. Prospective 

 purchasers of calcium arsenate should buy 

 only from reliable dealers, and should follow 

 directions for application carefully." 



Carbon bisulphide is now claimed to be the 

 most effective means of ridding orchards and 

 fields of ground squirrels and gophers. The 

 treatment now being used is what is known as 

 the waste ball method which when properly 

 applied, it is said, will kill 90 per cent of 

 rodent pests. The method of using the carbon 

 bisulphide waste ball is after opening the 



container to pour enough water on top of the 

 liquid to completely cover it so as to prevent 

 evaporation. In using a cork, seal with glue, 

 mucilage or glycerine. Place the required 

 number of waste balls in a bucket and pour 

 in enough carbon bisulphide to completely 

 cover them. Then place a waste ball in every 

 burrow of the colony or village. Allow at 

 least two minutes for the gas to permeate the 

 burrows, and then ignite the gas in each bur- 

 row with a torch or match. Please be careful 

 when igniting the gas; the operator should 

 stand well to one side when doing this. The 

 waste balls should be dropped as deeply as 

 possible in the burrows and care should be 

 taken not to cover them when closing the open- 

 ing or mouth of the burrow. When all the 

 burrows have been ignited close them up, 

 using plenty of earth; pack the opening of the 

 burrows tightly with the feet. Be careful in 

 igniting the gas that there is no dry vegeta- 

 tion around the burrows as the burning gas 

 is liable to start a Are. 



In planting your cherry orchard do not for- 

 get your poUenizers. As you will probably 

 plant Royal Annes, Bings or Lamberts, the 

 varieties that will pollenize these standard 

 cherries arc the Long Stemmed Waterhouse, 

 Tartarian, Black Republican, Coe, Elton, Wood 

 and a number of seedlings. The Long Stemmed 

 Waterhouse is considered the best as apart 

 from its being one of the most efficient poUen- 

 izers it brings a price on the market almost 

 equal to the Royal Ann, Ring, or Lambert. 



Remarkable results are now being obtained 

 by the use of sulphur for many soil crops and 

 in preparing soils to secure more complete 

 action from the use of other fertilizers. Some 

 of the highly desirable results secured through 

 the use of sulphur are that it improves alkali 

 soils, promotes nitrification and transforms 

 latent phosphates and potash into available 

 plant food. If you are interested in using 

 sulphur you will find it worth while to secure 

 a bulletin on the subject from your nearest 

 agricultural college experiment station. 



The home garden on the fruit ranch should 

 not be neglected or forgotten. To secure the 

 best results the garden should be planted in 

 long, straight rows and cultivated once a 

 week with a horse, according to United States 

 Department of Agriculture specialists. If this 

 much is done by the men the work of the 

 women will be materially reduced. The care 

 of a home garden is not hard work if the 

 fitting of the land and the main part of the 

 cultivation is done with horse-drawn tools. 

 Plan the farm garden right, work it right, and 

 it will prove the most profitable piece of land 

 on the farm.
