TUKNIP FLY. 20 



without having to knock it about too much in a dry hot time, have 

 much less trouble with the fly than those who give extra ploughing, 

 harrowing, &o., thinking to make a good use of the opportunity to get 

 their land clean. When land is in good condition, well managed, and 

 liberally manured, and the seed sown thickly, the plant will generally 

 get into rough leaf in spite of the fly, and grow so quickly as to defy 

 its attack. (T. H.) 



It is very desirable to work the land well, and get it fine and 

 moderately close, keeping in the moisture as much as possible, at the 

 same time stimulating the young plants with superphosphate or other 

 Turnip manures. (B. B.) 



TILTH. A fine tilth is most desirable ; the parts of a field first 

 hopelessly injured are those where the surface is the roughest, the 

 small clods causing the moisture to dry out more quickly, and afford- 

 ing shelter for the fly from breezes which they do not like. All the 

 preventives I have seen applied either to the seed or to the crop when 

 attacked have been total failures. (T. H.) 



Good tilth and condition are the chief auxiliaries to push the plant 

 out of the way of the fly. (J. B. J.j 



The finer tilth that can be got before sowing the better, and 

 as to manure, I should recommend a liberal supply of whatever kind 

 is used. (W. H.) 



I should add, as to the Turnip Fly, the finer the tilth the less are 

 its ravages. (C. H.) 



I know of no remedy, but like to have my land in fine condition 

 and well-manured, so that the plant may make the best use of its time 

 in getting out of the way of the pest. (E. S.) 



As a rule ground is not sufficiently worked for root-crops, as, when 

 hot dry weather sets in, the soil gets hard, and it is with difficulty 

 the ground is brought into a good condition to receive the seed. I 

 think the finer the tilth the better for all small seeds. (A. S.) 



I have always seen that the finer the ground is got before cultiva- 

 tion the quicker the plants come away, and the better and faster they 

 grow out of the way of the fly. (E. E.) 



I think it is best to hoe as soon as the drills of seed can be seen, 

 which will be much sooner if the tilth is fine, which I consider very 

 necessary for all small seeds. (T. J. M.)
