Every season growers are learning more and more the value of 

 spraying, and in many cases as high a percentage as 98 or 99 of clean 

 fruit has been produced in well-sprayed orchards. 



Various tobacco mixtures have been tried with good results, the 

 nicotine spray being especially useful in connexion with the Thrips 

 pest in potatoes. 



"BAVE-U" POWER SPRAYER. 



Benzole emulsion continues to be effectual in dealing with Thrips, 

 and by means of the " Strawsonizer " machine, placed in an ordinary 

 cart and worked by hand, the work can be carried out effectively. 

 Red oil and crude petroleum have given excellent results against 

 Scale insects, Red Spider, and Woolly Aphis. 



Lime and sulphur has proved the best spray for Peach Aphis, the 

 spraying, of course, being done while the trees are dormant.
