Regarding Our Latest Spraying Material 



"BLACK LEAF 40" 



From O. E. BREMNER 



Secretary of California State Commission of Horti- 

 culture: 



I am convinced in my own mind that "Black Leaf 40" will prove a 

 great success on young lecaniums and other soft-bodied scale insects, 

 also white fly larvK (A. citri), when used in combination with a small 

 amount of oil emulsion or soap. 



I have seen its efficiency thoroughly tested on thrips, and have used 

 the same combination, "Black Leaf 40" and 2 per cent oil emulsion, on 

 red spider with remarkable success. 



I have also used "Black Leaf 40" in combination with arsenate of 

 lead for calyx spraying of apples, and not only prevented the attack 

 of codling moth, but completely controlled the curl leaf aphis, which 

 has been such a destructive pest for the past few years. 



From W. H. VOLCK 



Entomologist for Monterey and Santa Cruz Counties, 

 California: 



I Iiave conducted a considerable number of experiments with "Black 

 Leaf 40," mainly to determine its efficiency in the control of aphids. 

 including the green aphis and the woolly aphis of the apple. All of 

 these tests have proved the material to be highly satisfactory for the 

 purpose mentioned. 



I consider your "Black Leaf 40" better for general use than your 

 "Black Leaf" Extract, since the amount of organic matter other than 

 nicotine is reduced to minimum. "Black Leaf 40" can be used without 

 leaving any stains or marks on the fruit, which is strongly to its 

 advantage. 



I find that one part of "Black Leaf 40" to 2,000 parts of water 

 containing cresol soap is very effective in controlling all kinds of 

 plant lice. 



I shall recommend its use in preference to any other form of 

 extracted or concentrated nicotine. 



From FRED L. YEAW 



California Agricultural Experiment Station: 



I used your "Black Leaf 40" against soft-bodied insects, using the 

 formula published upon your wrappers; the results were all that could 

 be desired, the spray acting very quickly. 



The "Black Leaf 40" would seem to be a very desirable kind of 

 tobacco spray to use, because of its known strength and non-volatile 

 qualities. 



From ELMORE CHASE 



Deputy Horticultural Commissioner, Fair Oaks, Cali- 

 fornia: 



We have used "Black I^eaf 40" straight on a small block of olive 

 trees for the black scale (Scaisseta Oleae), and after two weeks we 

 found every scale dead on the leaves which did not escape the spray. 

 For aphis it is a complete remedy. We are using a little from one 

 package with distillate emulsion for the scale of the olive. 



From PROFESSOR H. J. QUAYLE 



Entomologist California Agricultural Experiment 

 Station: 



We have tried the "Black Leaf 40" on plants of various kinds for 

 aphis, and find it entirely satisfactory for killing these insects. 



From PROFESSOR C. P. GILLETTE 



Colorado Agricultural Experiment Station: 



I have found a thorough application of "Black Leaf 40" in the 

 proportion of 1 to 1,000 to either green apple aphis or the woolly 

 apple aphis will kill 100 per cent of those actually treated. 



From GEORGE P. WELDON 



Field Entomologist Colorado Agricultural Experiment 

 Station: 



Have experimented with "Black Leaf 40" for the past two seasons, 

 and am satisfied that it is just as effective in killing the various species 

 of plant lice as "Black Leaf" Extract, which has for a number of years 

 been our standard remedy in Colorado for these insects. 



From PROFESSOR W. S. THORNBER 



Washington Agricultural Experiment Station: 



We are trying "Black Leaf 40" in various ways in our experimental 

 work, and Iiave found it very satisfactory so far. 



From DR. JOHN B. SMITH 



Entomologist New Jersey Agricultural Experiment 

 Station: 



"Black I..eaf 40" (Sulphate of Nicotine) proved satisfactorily effec- 

 tive on green plum aphis at the rate of one ounce to eight gallons of 

 water (a dilution of 1 to 1,024). 



From H. B. FULLERTON 



Director Agricultural Development, Medford, Long 

 Island: 



Your "Black Leaf 40" has proven very valuable to us this year. 

 We have used it in combating aphis, which this season have developed 

 in unusual numbers and representing a very great number of varieties. 



From A. W. MORRILL 



Arizona Horticultural Commission: 



It is my impression so far that for general pvirposes the strengths 

 that you recommend for "Black Leaf 40" are about correct. 



From GEORGE A. LAMIMAN 



Horticultural Commissioner, Anderson, California: 



"Black Leaf 40" seems to be a good remedy for the vine hopper on 

 grapes. It did good work on aphis, also on thrips in general. 



From PROFESSOR C. E. SANBORN 



Entomologist Oklahoma Agricultural Experiment 

 Station: 



I am very greatly pleased with our experiments in which we used 

 your products. 



Some Details About "BLACK LEAF 40" 



"Black Leaf 40" is a concentrated solution containing 40 per cent nicotine by weight, in the form of nicotine 

 sulphate. 



"Black Leaf 40" is nearly fourteen times stronger than our "Black Leaf" Tobacco Extract. This means a big 

 saving in handling — particularly over rough roads — one lOJ/^-pound tin producing 1,000 gallons of effective spraying 

 material against green aphis, etc. 



Owdng to the large dilution, neither foHage nor fruit is stained. 



Like our "Black Leaf" Extract, "Black Leaf 40" may be applied when the trees are in full bloom and foliage with- 

 out damage to either. 



Also, "Black Leaf 40" is perfectly soluble in water — no clogging of nozzles.
