This may be used as a summer wash at the rate of J pound to the

Proprietary Mixtures. 



In the search for better remedies for the San Jose scale, a number 

 of oil mixtures have been placed on the market in the United States and 

 Canada and extensively advertised as sure cures for the scale. Among 

 these may be mentioned Kil-O-Scale, Scalecide, and Target Brand Scale 

 Destroyer. Extensive experiments have been carried on with these mix- 

 tures with very varying results. The consensus of opinion seems to be 

 that at the strength recommended by the manufacturers, these mixtures 

 will not give uniformly good results, and that if used at strengths suf- 

 ficient to hold the scale in check, the cost of the resultant mixture would 

 be so great as to preclude its use in commercial orchards. For the small 

 home orchard, or for use on ornamental or fruit trees and bushes in city 

 or town lots, these mixtures, on account of ease in preparation and free- 

 dom from the caustic action so disagreeable with the lime-sulphur mix- 

 tures, will likely find a fairly large market. Until further improvement 

 in the mixtures themselves, or a decided reduction in the price has been 

 made, their use in the larger field of operation is not recommended. 



Treatment for Scale in the United States. 



Below will be found a number of extracts from the latest bulletins 

 and addresses on the San Jose Scale : — 



Mr. L. L. Morrell, Kinderhook, N.Y. , before the New York State 

 Fruit Growers' Association, January 3, 1907, said in part : 



"It is a fight first, last and all the time. I have had the scale for 

 sixteen years, have used all the different remedies of the past up to lime 

 and sulphur, which I am using now. I use 15 pounds sulphur, 20 pounds 

 lime, in 50 gallons of water, the sulphur being put in after the lime has 

 slaked; I boil it by steam until it is a dark amber color, at least one- 

 half hour, and then apply while hot. I can put on 800 to 1,000 gallons 

 per day with two men besides myself. It requires your absolute atten-
