"The stage at which cold 

 water should be poured in to 

 stop the cooking varies with 

 different limes. Some limes 

 are so sluggish in slaking 

 that it is difficult to obtain 

 enough heat from them to 

 cook the mixture, while other 

 limes become intensely hot 

 on slaking and care must be 

 taken not to allow the boiling 

 to proceed too far. If the 

 mixture is allowed to remain 

 hot fifteen or twenty minutes 

 after the slaking is completed 

 the sulphur gradually goes 

 into solution, combining with 

 the lime to form sulphids, 

 which are injurious to peach 

 foliage. It is therefore very 

 important, especially with hot 

 lime, to cool the mixture 

 quickly by adding a few 

 bucketfuls of water as soon 

 as the lumps of lime have 

 slaked down. The intense 

 heat, violent boiling and con- 

 stant stirring result in the 

 production of a uniform mix- 

 ture of finely divided sulphur 

 and lime, with only a very 

 small percentage of the sulphur in solu- 

 tion. The mixture should be strained to 

 take out the coarse particles of lime, but 

 the sulphur should be carefully worked 

 through the strainer. 



"In applying the self-boiled lime-sul- 

 phur mixture the spraying outfit should 

 be equipped with a good agitator. The 

 mixture settles to the bottom of the 

 tank, and unless kept thoroughly agi- 

 tated cannot be evenly applied." 



Since commercial lime-sulphur has 

 caused some burning of fruit and foliage 

 of the apple in some sections of the 

 Northwest we would suggest that the 

 self-boiled lime-sulphur be tried for the 

 third scab spray. Either the 8-8-50 or

10-10-50 formula may be used. While 

 not as good as the commercial lime- 

 sulphur against apple scab Scott finds 

 that it will control mild cases of scab, 

 and in his experiments was entirely 

 harmless to foliage and fruit. 



Arsenate of lead for codling moth may 

 be safely used with the self-boiled mix- 

 ture in the same proportions as recom- 

 mended when mixed with bordeaux or 

 commercial lime-sulphur. 



It is often desirable and practicable to 

 use sprays which combine both fungi- 

 cidal and insecticidal qualities. The 

 time, expense and annoyance of one or 

 more sprayings may frequently be elimi- 

 nated by such combinations. Thus bor-

deaux mixture and paris green, or arsen- 

 ate of lead, has long been used as a 

 combined spray for apple scab and cod- 

 ling moth, and the expense of control- 

 ling these two important apple pests has 

 thereby been materially reduced. This 

 spray, however, combines only the fungi- 

 cidal value of bordeaux and the food 

 poison value of the arsenical. It is of 

 little or no value as a contact insecti- 

 cide; in other words, it is of no value 

 against scale insects, plant lice and other 

 sucking insects. 



During the past four years we have 

 conclusively demonstrated that the lime- 

 sulphur spray, which has long been 

 known as the most satisfactory winter 

 spray for San Jose scale, has 

 fungicidal qualities nearly or 

 quite equal to those of bor- 

 deaux. We have also conclu- 

 sively demonstrated that it 

 may be used in combination 

 with arsenate of lead without 

 detracting from the value of 

 either, and that when so used 

 it is at once an efficient con- 

 tact insecticide, food poison 

 spray and fungicide. 



It also has the advantage 

 that when properly diluted it 

 may be used either as a win- 

 ter or summer spray. 



As a winter spray one ap- 

 plication of the lime-sulphur 

 spray each year will do more 

 for the neglected orchard than 

 can be done in any other way 

 by the same expenditure of 

 cash and energy. It not only 

 destroys San Jose scale, but 

 it also destroys the branch 

 form of woolly aphis, the 

 eggs of the green aphis, the 

 pear leaf blister mite, the 

 hibernating larvae of the bud
