138 PROCEEDINGS OF THE SECOND ENTOMOLOGICAL MEETING 
Crude Oil Emulsion :— 
(a) smearing setts. 
(6) dipping setts in solution. 
(c) earth mixed with Crude Oil Emulsion spread in furrows. 
in which setts planted. 
Fish Oil Resin :— 
(a) smearing setts. 
(6) dipping setts in solution. 
Creosote :— 
(a) setts dipped in creosote. 
(6) ends of setts dipped in creosote. 
(c) creosoted earth in furrows in which setts planted. 
Sanitary Fluid—setts dipped in solution. 
Copper Sulphate :— 
(a) dipped in saturated solution. 
(6) powder mixed with earth. 
Clifts Powder—mixed with earth. 
Apterite. 
Formalin—setts dipped in solution, strength 1 per cent. to 
5 per cent. 
Of all these, Lead Arsenate has up till now been found to be the best. 
The setts are dipped in solution (1 lb. Lead Arsenate in 2 gallons cold 
water) and dried in shade and then planted. 
Our experience is that it is not so much setts as the new shoots which 
require protection. Frequently the untreated setts sprout as well as 
the treated ones and the termites do the real damage to the new shoots. 
{t has been observed that treatment with Lead Arsenate affords some 
protection to the new shoots. Further experiments will be undertaken 
on this line, that is to say, the subsequent use of measures to protect 
the newly-sprouted shoots. 
In the Punjab, at Gurdaspur comparative trials were made with 
Lead Arsenate, Crude Oil Emulsion, and Copper Sulphate. Lead 
Arsenate and Crude Oil Emulsion gave good results, but Crude Oil 
Kmulsion had to be continued for a month, being applied in the irriga- 
tion water. 
At Coimbatore some experiments were started two years ago, but 
unfortunately they were not carried to a finish. The following insec- 
ticides were tried :— 
(1) Dipping the setts in Crude Oil Emulsion. 
(2) Dipping the setts in Fish Oil Soap. 
(3) Dipping the setts in dilute solution of Mercury Perchloride 
(1 in 2,000).
