Cutworms. 



These cause considerable loss, especially in chrysantliemurus, but as soon as 

 their presence is noticed they can be easily eradicated and destroyed by the use of 

 poison bran. Take a pail of bran and thorousrhly mix in about 1 to 1% oz. of Paris 

 green, then moisten with sweetened water and spread on the ground and on the 

 benches on which the plants are attacked, and in the course of a day i>r two these 

 pests will have disappeared. 



In this paper I have not dealt with all the insect pests that cause loss to the 

 grower of plants, etc., under glass, but have dealt with the most important which 

 trouble us in this district. 



In conclusion, I would strongly impress ujion the grower to keep a close watch 

 at all times foi- any signs of attack, and at once use the remedies recommended. 

 Do not consider the expense of purchasing the different sprays, as you will lose 

 ten times the amount that these will cost by allowing your plants to be overrun. 



I would like to call the attention of this Society to the advisability of approach- 

 ing the Dominion Government regarding the removal of duty on all nicotine solutions, 

 such as nicoticide, nicotine, nico-fume. Black Leaf 40, etc. As far as I know, they 

 are not manufactured in Canada, or likely to be so. Now, as these preparations are 

 only used for the extermination of the natural enemies of the growers, I consider 

 it would be a good policy to enable the grower to procure these at the least possible 

 expense. 



Mr. Day : Any questions you would like to ask about this paper? Mr. Treherne 

 will be pleased to give you any explanations he can. 



Question : What is the best way to destroy insects that get down into the root 

 of the cabbage? 



Mr. Treherne: That is a fly known as the cabbage-maggot, and it is a little 

 white grub at the root of the cabbage. It is the worst insect foiind in truck- 

 gardens, as it is believed to destroy 75 per cent, of the cabbages in this part of the 

 world. The best remedy against it is to get a piece of tar-paper and insert around 

 the plant on the surface of the ground. 



Question ; I tried it last year, but it did not have any effect. 



Jlr. Treherne : Perhaps your paper was too light ; if it is not heavy enough it 

 will curl with the sun. I'nder experimental work we have had 90 per cent, efficiency 

 during the last two years with this same method. There is a solution you can use ; 

 carbolic acid and soap mixed into a solution and dilute it 1 to 15 and pour aI)out 

 5 oz. around each plant once a week during the early part of the season, and it 

 will take about eight applications, but this solution will not give you as good results 

 as the tai--paper. 



Mr. T. Wilson : Talking about this same thing. I was talking to a gentleman at 

 Chilliwack, and he had tried both methods with a good deal of success. He used 

 this carbolic solution which I had told him about and he added so much arsenate of 

 lead, and before planting he dipped the roots into this solution and he had SO per 

 cent, success. 



Mr. Lyne: I believe that arsenate of lead diluted at the rale of 2 lli. to 50 

 gallons of water would not lie injurious to tlie plant, and would be a sufticient 

 quantity to stay on the plant: and if it did it would lie perfectly impossible for 

 the larvie to consume any of the plant. 



Question : I would like to hear more about the tar-paper. 



Mr. Treherne: Do you know how it works? You make u disk of the tar-paper 

 about 3 inches diameter with a slit in the centre, and as you put your plant in 

 the ground you place this disk flush to the surface of the ground around the neck 

 of the plant. The idea is that if the tar-paper is fresh it will kee]) the fly away; 

 and if it does not, the eggs will be laid on the surface and often perish.
