The New Method of Killing the San 

 Jose Scale 



A SOLUTION THAT IS BOTH EFFECTIVE AND IN- 

 EXPENSIVE IN DESTROYING THE PERNICIOUS 

 SAN JOSE SCALE, PSYLLA, ETC. 



This new preparation supplants the lime- 

 sulphur wash with its bothersome preparation, 

 boiling of ingredients and danger of serious 

 injury to the clothes and hands. 



The following is an extract concerning it 

 from the January 15th, 1906, Bulletin issued 

 by Professor S. A. Forbes, State Entomologist, 

 Urbana, 111.: 



" The time and labor necessary to the preparation of the 

 sulphur wash may be greatly saved by using as a substitute 

 a spray of soluble petroleum, made by diluting one part of 

 the commercial preparation known as ' Scalecide ' with nine- 

 teen parts of water. This material, made by the B. G. Pratt 

 Company, No. 1 1 Broadway, New York City, while more 

 expensive than the sulphur wash, may be used to advantage 

 in a small orchard or in a town lot." 



The above estimate by Professor Forbes was probably based 

 on small retail quantities, as the following extract from the 

 Rural New Yorker, January 20th, 1906, page 51, reporting 

 the N. J. State Hort. Society Meet: 



" The soluble oils are cheap and convenient, requiring only 

 mixture with a proper amount of water, and make ideal appli- 

 cations from the sprayer's standpoint. A comparative trial 

 made by the Pennsylvania Railroad Company in spraying 

 fourteen miles of Osage orange hedge showed the soluble oils 

 to be cheaper than lime and sulphur when all charges for labor 

 and fuel, as well as first cost of materials, were reckoned 

 up." 



Furthermore, one gallon of ' Scalecide" spray, 

 costing less than 3 cents per gallon delivered at 

 at any railroad station in the United States, will 

 cover as much surface as one and one-half to 

 two gallons of lime, sulphur and salt wash. 



Professor Haughton, Delaware Experiment Station, writes of 

 " Scalecide ": " I used your preparation this spring on Apple, 

 Pear, Peach and Plum trees, badly infected with San Jose 

 Scale, at the rate of 1 part to 20 parts of water, with very 

 satisfactory results." 



Prof. John B. Smith, Entomologist, New Jersey Agricultural 

 Experiment Station, New Brunswick, N. J., July 27, 1905, 

 writes of " Scalecide ": " I believe that applied at the right time 

 and in a thorough manner, this is as good, if not a better 

 remedy, for this pernicious insect, than any we have up to 

 the present time." 



Mr. John R. Parker, Freehold, N. J., writes: "I have 

 closely examined my trees from time to time since July 1st, 

 and can say that I have found no young scale on trees sprayed 

 with ' Scalecide ' last March. 



" Mr. R. A. Ellis obtained some ' Scalecide ' from me, and 

 from results he says he has no fear of the scale." 



Prof. H. A. Gossard, Entomologist, Ohio Agricultural 

 Experiment Station, Wooster, Ohio, writes: "The oil we 

 used on San Jose Scale seems to be quite satisfactory." 



It has long been known that petroleum oils 

 would kill the scale if they could be mixed with 

 water so as to be conveniently applied. Scale- 

 cide is such a unique practical triumph. It is a 

 perfect mixture of oils that thoroughly satu- 

 rates the scale, causing it to curl up and die, 

 and fall off.

This is a new edition of the well-known and 

 classic treatise on garden vegetables first 

 issued in English in 1885, and is a valuable 

 reference book to the student. The treatment 

 is on the dictionary plan. All the common 

 vegetables and nearly all the rare ones are 

 included in the new edition, but some of the 

 rarest have been dropped. The cultural 

 instructions being applicable only to English 

 and French conditions, as a practical work 

 it is inadequate for the American reader, but 

 to the student who goes beyond the mere 

 eating of garden crops the book is invaluable. 



Recipe for Lime-Sulphur Wash 



To make the lime -sulphur wash bring a 

 couple of gallons of water to boil in an old 

 kettle and to it add two pounds of good quality 

 freshly burnt or stone lime. Then add one 

 and one-half pounds of sulphur which has 

 been made into a paste by stirring with a 

 little water so that it will mix better. Stir 

 thoroughly. Boil at least half an hour — 

 better an hour — then remove and strain 

 thoroughly through netting or sieve and 

 dilute to make five gallons. This should 

 cover five four-year-old peach trees. For 

 larger amounts make in the same way, using 

 twenty pounds of lime and fifteen of sulphur 

 to fifty gallons of water. Where much is 

 being made and steam is available, it can 

 often be boiled right in the barrel by using 

 a jet of steam. It is sticky, disagreeable stuff 

 and old clothes and gloves will be needed in 

 its application. The uses of this wash are 

 fully discussed on page 64.
