treatment will destroy the worms in large numbers lias not been 

 proved ; but. even if it does not do this, it will help the vines to re- 

 cover from their injury more quickly. lUirning the vines on a badly 

 infested area is to be recommended, as they are practically destroyed 

 anyway, and the benefit derived from the killing of the worms will 

 more than make up for any loss incurred by such treatment; and 

 the area burned over may then be reset at once. The burning should 

 be done with a gasoline torch, at a time when the vines will not 

 otherwise burn readily, in order to guard against setting a fire which 

 might escape from control, and it should be done early in the season 

 before the growth starts. 



The flooding of an infested bog for a week or ten days immedi- 

 ately after picking has been found to give satisfactory results by those 

 growers who have tried it, and as this method of treatment also helps 

 against the fruit worm, it is to be especially recommended. The fact 

 that the moths begin fiying in considerable numbers in early June, 

 and that they take readily to grasses and other plants growing on 

 the upland suggests another remedy for bogs with abundant water 

 supply for reflowage. 



Kcconu)ie)idations for IrcatDiciit : — 



A, On bogs which can be reflowed : — 



1. Rejfow immediately after picking, for a week or ten days. 



2. If the early fall flowing has been Jieglected, i-eflow for a day or 

 two about the lOth of fime. 



S. On dry bogs : — 



1. Burn infested areas as indicated abo7'e. 



2. Heavy sanding would probably be advantageous. 



SPITTLE INSECTS. 



These peculiar insects, which form little masses of froth on the 

 vines, sometimes appear in large numbers, and are believed by many 

 growers to cause considerable injury. While it is true that they suck 

 some juice from the vines, they do not kill the uprights nor do they 

 prevent them from developing fruit satisfactorily.
