576 ANNUAL, REPORT OF THE Off. Doc. 



I agree with most of the speakers in not advising short cuts. 

 Lime, sulphur and salt is not a new thing; it has been used in Cali- 

 fornia for some years and it is worth following. The long boiling 

 makes a perfect combination of lime, sulphur, and salt makes it 

 adhere. This caustic addition is on trial. It is recommended to 

 avoid long boiling. It adds to the expense of the wash, but under 

 no circumstances can you get lime and sulphur to have the same 

 effect of chemical union that you will by long boiling. We know 

 that the lime v/ill cut the sulphur and get it in solution, but you 

 don't get the caustic effect. The formula for lime, sulphur and salt 

 you may vary as you like. My own belief is that an extraordinary 

 amount of lime is unnecessary and makes it harder to spray. Thirty 

 pounds of lime to twenty pounds of sulphur and fifteen pounds of 

 salt in sixty gallons of water is about what it should be. I should 

 recommend a greater amount of lime in the mixture because that 

 is good for the tree and you can see what you have done. However, 

 the more lime you have the more difficult it will be to get it through 

 the nozzle and I should not use more than thirty x)Ounds of lime to 

 twenty pounds of sulphur. 



DE. FUNK : Why should I have an increase of lime and use more 

 lime than sulphur? 



PROFESSOR MARLATT: Bv using more lime vou have the tree 

 more whitened and can see it. 



DR. FUNK: You get that vellowish white on the trees after 

 it is dried and is thoroughly effective. 



PROFESSOR MARLATT: It don't make any difference what you 

 use, you get perfect results. You can use equal parts of lime and 

 sulphur and get practicalh^ the same results. 



The PRESIDENT: You use sulphur and lime but advise using 

 more lime than sulphur in the mixture because it gives it color. 



PROFESSOR MARLATT: It gives color and is more adhesive. 



The PRESIDENT: How much salt do you say you would use? 



PROFESSOR MARLATT: Fifteen pounds. 



The PRESIDENT: How much water? 



PROFESSOR MARLATT: Sixtv gallons of water. 



PROFESSOR SURFACE: That is the same formula in our No- 

 vember Bulletin, except we put forty pounds of lime in. 



The PRESIDENT: ^^•hat do you mean by a long boiling? 



PROF. MARLATT: If you should prepare fifty or sixty gallons,
