Destruction of Charlock. 



[Oct.,. 



Ashton, Somerset, it was found possible to produce a very 

 palatable jelly without' the addition of sugar or glucose., 

 although, needless to say, better results are obtained if at least 

 half the usual quantity of sugar is used. By following this 

 method, a supply of home-made jelly can be simply and 

 inexpensively made in districts where cider-apple juice is 

 obtainable. The cider apples especially suitable are the sweet 

 and bitter-sweet varieties. Sharp or sour varieties will, if 

 used by themselves, give a jelly of too acid a flavour. They 

 •can, however, be used, if mixed in small quantities with the 

 sweet and bitter sweets. "The method of making the jelly, the- 

 kinds of apples required, and other uses of concentrated apple- 

 juice, are explained in a leaflet which can be obtained on 

 application to the Agricultural and Horticultural Research 

 Station, Long Ashton, Bristol, to which address any inquiries- 

 should be directed. It may be added that, although cider 

 apples are not generally used for domestic cookery, they may 

 be made quite suitable for this purpose by the addition of 

 tartaric acid. Information on this point also can be obtained 

 from the same quarter. This year the cider apple crop may 

 not yield a surplus, but in cases where wastage is likely to- 

 occur, it can be obviated by using the fruit as indicated here.

Successful experiments in the destruction of charlock have- 

 been carried out this year on two cornfields, part of the-

 had formed, and the second field at the beginning of June, 

 when numerous plants were in flower. The weather con- 

 ditions during the spraying of the first field were for the most 

 part dull and wet, while parts of the second field were sprayed 

 under both wet and dry conditions. 



The spraying was successful whether the charlock had' 

 flowered or not, and whether the operation was car- 

 ried out in wet or dry weather. Spraying when - the 

 charlock was in flower was more effective than earlier 

 spraying, and the drier the condition of the crop- 

 the more drastic was the effect of the copper sulphate on the-
