Established Fruit Trees 



sisting of one part lime and three parts flowers of 

 sulphur was found to be efficacious. Spraying the 

 bushes with various washes has also been successful, 

 and I prefer this method to the former, as it occupies 

 less time. Paraffin emulsion and quassia extract 

 may be used either separately or together, and one 

 grower in Northants, whose trees were at one time 

 almost useless, recently informed me by letter : 

 " We had a very good crop of currants from the 

 trees which you treated." 



Examine the buds from mid-February onwards. 

 The treatment, whether " wet " or " dry," should 

 commence when the mites begin to leave the buds, 

 and this usually happens in March, but the time 

 varies, of course, according to the locality and to 

 the mildness of the season. 



I find that three sprayings with intervals of a 

 fortnight are really necessary when the mites 

 are plentiful. Winter spraying with either of the 

 washes mentioned above is well worth while, as it 

 will be easier to deal with the mites on clean bark 

 during the summer. 



Some varieties are attacked worse than others. 

 " Baldwin's Black " suffers most, and " Boskoop 

 Giant " least of all. In propagating, only clean, 

 healthy cuttings should be used, and Pickering 

 recommends immersing these in water at 115 

 Farenheit for ten minutes before planting. 



Finally, regular pruning and a plentiful supply 

 of manure will do much towards keeping bushes 

 immune from attacks, and, if the directions given 

 above are properly carried out, growers will find that 

 it is still possible to produce paying crops of black 

 currants.
