CABBAGE AND TURNIP-ROOT MAGGOT. 
15 
A maggot, which on examination proved to he Cabbage-root 
maggot, was also reported from Stanton-in-Peak, Bakewell, as infest¬ 
ing a crop of Swedes, and attacking, though in a lesser degree, 
common Turnips sown in the same field; and, going further north, 
Mr. Robert Service, Dumfries, mentions the attack as present in that 
neighbourhood early in the season. 
Looking at the various localities given, the attack both to Cabbage 
and Turnip appears to have been prevalent over the country from 
Glasgow to the South Coast. 
The following observations on attack of Cabbage and Turnip 
Maggot in North Britain also point to it being fostered by large appli¬ 
cation of farm manure, and checked by the application of lime, gas- 
lime, or artificial manure. 
Mr. J. Spier, Newton, Glasgow, notes :—“ I was greatly annoyed 
by the Turnip maggot in 1881. My crop was Golden Ball for early 
bunching for table use. They were manured with stable-dung in the 
drill, and sown in two rows on the drill. 
“ During June the maggot made such havoc among them as to 
reduce the available plants to about half a crop. That same season the 
maggot was tremendously bad on all Cabbage plants throughout the 
south-west of Scotland, many plots being almost destroyed. My own 
were worst on the heaviest-manured pieces.” 
Mr. George McKinlay, The Gardens, Kilconquliar, Fifeshire, notes 
the attack of the Cabbage-root maggot as almost certain to be trouble¬ 
some to the grower if he is obliged to use fresh farm-yard manure. 
Such had been his own case in the past season ; consequently the Cab¬ 
bage and Cauliflower plot had to be replanted three times. 
Owing to these attacks, when the sun shone out bright on a brake 
of Cauliflowers which had looked well up to this time, thirty to fifty 
would droop, and when pulled up were found to be attacked by 
maggot. 
The remedy found most effective was some lime-shell put into a 
barrel of water, and allowed to remain forty-eight hours (when it was 
quite clean), and then applied to each plant, as by taking them 
straight forwards the pest is found to be stamped out. 
In regard to my enquiries regarding prevention of Cabbage-root 
maggot, Mr. Boyd, Callendar Park Gardens, Falkirk, replied that 
where he had used gas-lime he had been free from attack, whilst at the 
other places where it had not been used the attack was very bad. 
He mentions :—“ In one instance I lost the whole crop of four 
rows of Cauliflower, and I am satisfied you are right about farm 
manure attracting the Cabbage Fly, as the four rows of Cauliflower 
were grown between the Asparagus beds, and in early spring the 
manure that covered the beds was raked off and dug in between them
