It is the foundation of health and human 

 energy. It produces the stamina and the strengtii 

 to do things. On the field of battle — as well as 

 on the tables where peace and plenty reign — 

 chocolate has proved it«elt a ioo% food.

'riu' iiio.st important disadvantage is 

 llu- fact that they cannot be u.scd with 

 lead ai'scnate as a combination spray. 

 When used on foliatjc they are some- 

 what more caustic than the lime-sulphur 

 solution. 



Summarizing the above, it appears 

 that the alkali polysulphides are efTec- 

 tivc, convenient, and have some advan- 

 tages over lime-sulphur solution and 

 some disadvantages. Taking everything 

 into consideration, these compounds do 

 not possess enough advantages to war- 

 i-ant using them in preference to the 

 older well-established and standard 

 lime-sulphur solution, except in .some 

 cases as a combination spray. 

 Dry Lime-Sulphur. 



Samples of this material have been 

 analyzed by the laboratory and found 

 to contain the same constituents as 

 lime-sulphur solution, that is, polysul- 

 phides and thiosulphate of lime. In 

 addition, however, they contain about 

 20 per cent organic matter. The mate- 

 rial does not go entirely into solution 

 in cold water and there is some free 

 sulphur. 



So far as can be judged, the dry form 

 of lime-sulphur when dissolved in water 

 will produce a spray in all respects 

 similar to the usual dilution of lime- 

 sulphur solution, provided equivalent 

 ([uantities are used. The chief point 

 for consideration, then, in choosing be- 

 tween the dry form and the solution, is 

 the cost. Comparative costs are shown 

 in the table above. 



If the manufacturer's directions for 

 winter spraying arc followed (10 to 12 

 ])ounds of dry lime-sulphur dissolved in 

 ,50 gallons of water) a spray will be 

 obtained containing only about one-half 

 as much active sulphur as in the cus- 

 tomary 1 to 10 dilution of lime-sulphur 

 solution. In defense of this half-strength 

 reconmiendation the manufacturers say 

 that certain organic material which is 

 incorporated into their dry compound 

 prolongs the effeclivenescs of the ap- 

 plied spray so that much less than the 

 usual amount of sulphur is required. 

 .\ somewhat similar claim is made by 

 the manufacturers of soda-sulphur com- 

 pound. Field tests have not been made 

 in California to determine whether or 

 not these claims are valid. 



This laboratory, therefore, will still 

 continue to evaluate these and similar 

 preparations of sulphur on the basis of 

 the percentage of sulphur combined in 

 the form of polysulphides and thio- 

 sulphate. 



The fruit growers of California can- 

 not afford, for the same of convenience, 

 to set aside a well-established and thor- 

 oughly-tested spray practice and reduce 

 their remedies to half-strength unless 

 this has been shown to be feasible by 

 experiments of the most convincing 

 sort. It would be better to use full- 

 strength at double the cost.
