ANIMALS INJURIOUS TO FRUIT TREES. 1 7 



Winter spraying- with caustic soda and other winter washes does 



not seem to have any effect upon this pest so far as my observations 

 go, but I believe that a fluid consisting- of 



Potassium Sulphide ... ... i| Ibs. 



Soft Soap ... ... ... i|lbs. 



Lime ... ... ... i^lbs. 



Water ... ... ... 50 gallons. 



sprayed early in September, would destroy large numbers of the mites 

 as they leave the leaves and migrate to their winter quarters. 



All nursery stock should be fumigated with hydrocyanic arid 

 gas, whilst in a dormant condition. 



THE BLACK CURRANT GALL-MITE. 



Eriophyes ribis (Nalepa). 



Judging from the letters I still continue to receive from all parts 

 of the British Isles, the results obtained by the application of lime 

 and sulphur has exceeded my most sanguine expectations. 



The remedy has been scoffed at by certain individuals, no doubt 

 owing to its simplicity, but no such childish actions can alter the 

 fact that whereas five years ago the cultivation of Black Currants was 

 despaired of in the United Kingdom, now large quantities are being 

 cultivated free from " Big-bud. 1 ' 



The remedy has, of course, failed where it has been misapplied, 

 or where the quantities have not been carefully measured, but where 

 the work has been properly done it has been successful in 90 per cent, 

 of cases. 



As the earlier Reports are out of print, I again repeat the method. 



Mix one part of ground unslaked lime with four parts of sulphur 

 and dust on the bushes, when the dew r is on them, as soon as the leaves 

 have opened. A fortnight or so later dust again with one part of lime 

 to eight parts of sulphur, and again at a similar interval with sulphur 

 only. 



RED " SPIDER" ON APPLE TREES. 



Numerous complaints have been received from Worcestershire 

 fruit growers of the extraordinary prevalence of Red " Spider " on 

 Apple trees. In some cases gooseberry bushes were growing between 

 the trees, but in others this was not so. 



Considerable losses were occasioned in not a few cases.
