Control 



Scammell (6) says an arsenical added to the customary Bordeaux/and resin- 

 fish oil soap is of value in killing the beetles on cranberry. Arsenate of lead, 

 13^ pounds to 50 gallons of water, has been recommended for cranberry but two 

 applications should be made. 



Franklin (8) states, after spraying cranberries with 2M pounds lead arse- 

 nate and 1^ teaspoondulls white arsenic to 40 gallons of w-ater dead rootworm 

 beetles were found in large numbers under the vines and only a few were 

 crawling about. 



Acording to Sawyer, (12) attemps to kill the beetles on apples b}- spraj'ing 

 with arsenate of lead were unsuccessful. Lead arsenate (powdered), 5 pounds, 

 in 100 gallons summer strength lime-sulphur, was applied with great thorough- 

 ness without either killing the beetles or driving them away. 



In a previous article. (13), I stated that the trees at Rougemont had been 

 sprayed three times with Bordeaux mixture (4-4-40) and powdered lead arse- 

 nate, 13^ pounds to 40 gallons, before the infestation was examined on July 12. 

 They were sprayed a fourth time on July 14 with the mixture just mentioned. 

 The trees were examined five days later but the beetles were still present in 

 large numbers. Apparently, the ordinary sprays are of little or no value in its 

 control on apple. These sprays will have to be improved or other methods, 

 devised, if the insect is to be controlled. Should this insect spread and esta- 

 blish itself in this province, it will cause very serious losses to our orchardists.
