MATERIALS FOR DESTROYING NOXIOUS INSECTS. 185 



5. " IXL." — This so-called specific comes to us from 

 America with a very high reputation. It is, however, as 

 yet, too expensive for general use here, or to successfully 

 compete against the cheap and effective kerosene emul- 

 sions. 



6. " Phylloxera Cure " (Perry's) . — This is reputed, by 

 those who have tried it, to be effectual in clearing plants 

 of many kinds of scale-insects, and has been used with 

 success in the Carlton Gardens. I have had no experience 

 with it on vines which have been attacked by phylloxera. 



7. Soap (Garrick's Mineral). — This soap is intended 

 to supersede the ordinary soaps hitherto used for the pur- 

 pose of emulsifying the kerosene for spraying fruit trees. 

 It makes both a cheap, safe, and nearly perfect emulsion, 

 and is already largely in use in orchards and elsewhere. 



8. "Emulsion" (Martin's). — This, the most perfect 

 emulsion which I have yet seen, and when it can be placed 

 cheaply on the market, will, no doubt, be largely in 

 demand by growers. The kerosene emulsions are certain 

 to increase in popularity, and now that the emulsifying 

 process has been brought to such perfection, a large sale 

 of same is only to be expected. 



9. Sulphate of Copper (Bluestone). — This material, 

 in addition to its great value as a fungicide, has been 

 tried with success against the peach aphis when on the 

 roots of fruit-trees. 



10.* Sulphate of Ammonia. — Has been used T\dth 

 much success against the " Army-worm," " Cut-worm," 

 and similar pests. 



11. Sulphate of Potassium. — Has been used mixed 

 with the above (No. 10), and for similar purposes. 



* It will be of interest for farmers to know that, at the late trials of material in 

 use agamst caterpillars in the field-crops, and which took place in England, it 

 was found that the following gave the best results : — 



Sulph. of iron ... ... i cwt. ^ 



Sulph. of potass. ... ... 1 cwt, }- per acre. 



Sulph. of ammonia ... ... 1 cwt. J
