(2) Tobacco Wash. This is useful for Thrips, Leaf- 

 hoppers and Cuckoo-Spit. The quantities are : 



Tobacco i-lb. 



Soft soap .. ... .. ... i-lb. 



Water (soft) 12 gallons. 



Steep the tobacco in water for some days and then allow 

 it to simmer over a fire for an hour ; pour off the liquid, 

 well squash the leaves and proceed again as before, and 

 add the second extract to the first. This extract may 

 then be mixed with the dissolved soft soap. 



(3) Hellebore Wash. This wash is most useful for 

 Sawflies. Hellebore is used as a fine powder to dust 

 over these insects, but it is far best especially for Roses 

 used as a spray. It is made as follows : 



i-oz. of fresh ground hellebore. 

 2-ozs. of flour. 

 3 gallons of water. 



The hellebore and flour are mixed together with a little 

 water and then mixed with the rest of the three gallons. 

 It must be constantly stirred and sent out as a fine spray. 



(4) Ar senate of Lead. This is the only poisonous 

 wash for Caterpillars that can be used on Roses. It may 

 be obtained in a paste form known as Swift's Arsenate 

 Paste, or may be made as follows. 



Arsenate of soda (98 per cent.) i-oz. 



Acetate of lead (98 per cent.) 2f-ozs. 



Water .. ... .. .. 10 gallons. 



Place the two in water and stir until both are dissolved, 

 then add to the rest of the water and apply as a fine 

 spray. Paris green, which we have seen recommended, 

 will do more harm to the Roses than the insects. 



(5) Liver of Sulphur Wash. Useful in attacks of 

 Red Spider, and has fungicidal properties. For Roses 

 no more than i-oz. should be used to 10 gallons of water.
