64 EXPERIMENTAL FARMS 



6-7 EDWARD VII., A. 1907 



Jose Scale, and ' Investigations in Manitoba and British Columbia as Entomologist 

 and Botanist,' were printed in the annual report of the Hon. Minister of Agriculture 

 for 1895. 



Since 1884, when the Select Committee appointed by the House of Commons to 

 obtain information as to the agricultural interests of Canada met, the Entomologist has 

 been invited annually to give evidence before the Committee on Agriculture and Col- 

 onization of the House of Commons, upon the most important occurrences of insects 

 i}ijurious to crops and the most recent developments in methods of fighting them, and 

 also upon recent work with regard to grasses and other useful fodder plants. Reports 

 of this evidence have been published regularly, and through the generosity of the Print- 

 ing Committee have been supplied in such number, both in French and English, as 

 to allow of their being sent to all of the regular correspondents of the Division. In 

 this way a good opportunity has frequently been afforded of getting useful suggestions 

 into the hands of 'farmers sooner than would be possible through the annual reports 

 at the time they are usually issued. 



USEFUL INVESTIGATIOKS. 



Among the investigations which have claimed the attention of the officials and 

 with regard to which it is hoped that useful advice has been given to the farmers of 

 Canada, mention may be made of the following subjects which have been studied for 

 several years, and concerning which from time to time reports have been published. 

 No lengthy reference is here made to those insects wdiich have recently been treated 

 of in Bulletin 52 on Insects which cause injury to Grain Crops, Boots and Vege- 

 tables. It may, however, be thought justifiable to point out, that through the persist- 

 ent recommendations of this Division remedies for some of these which have saved 

 many thousands of dollars to the farmers of Canada, have been made widely known and 

 have been more generally used than might otherwise have been 'the case. In this cate- 

 gory are the following which it is believed are, all things considerd, the best remedies 

 for the different insects named: — 



The Hessian Ely. — Late sowing, the burning of refuse from the threshing mills,, 

 and the burning over or deep ploughing down of stubbles. 



The Joint-worms. — The burning over or deep ploughing of stubbles, burning 

 refuse, and a regular rotation of crops. 



The Greater Wheat-stem Maggot. — Late sowing. Trap crops sown in Julj' and 

 ploughed down in August. 



Cutworms. — Clean farming, so as to destroy all weeds in autumn when the moths 

 of many species lay their eggs. Poisoned bran-mash and poisoned baits. Special 

 mention may be made of the former, a most useful remedy. 



Grasshoppers or Locusts. — The Criddle mixture of fresh horse droppings poisoned 

 with Paris green. 



The Pea-weevil. — Systematic fumigation of all seed pease with bi-sulphide of car- 

 bon ; treating the seed with coal-oil ; holding over seed for two years. 



The Clover-seed Midge. — Cutting or feeding off the first crop of clover to be 

 saved for seed, by June 20. 



Small White Cabbage Butterfly, the parent of the ' Cabbage-worm.' — Dusting 

 cabbages, as soon as the caterpillars are seen to be destructive, with pyrethrum insect 

 powder, 1 lb. in 4 lbs of flour or some other perfectly dry powder as a diluent. 



Root Maggots of Radish and Onion. — Watering the young plants once a week 

 from the time they appear above the ground with the Cook Carbolic wash. Dusting 

 once a week with white hellebore or insect powder. 



Root Maggots of the Cabbage. — Dusting or watering around the roots after un- 

 covering them, with an infusion of pyrethrum or white hellebore, 1 oz. in a gallon of 

 water, at time of transplanting and aa-ain a week later.
