14 THE CABBAGE MAGGOT. 



Bran and Glue: Prepared as above, using- bran in place 

 of sawdust. This makes a closer pack about the plant, but 

 evidently does not go as far as the sawdust. I regard it as, 

 on many accounts, better than sawdust. 



Bran, Glue and Paris Green: Five ounces of Paris green 

 were stirred into a peck of glue and bran. This is sufficient 

 for about 30 plants. This was applied to 35 plants on June 

 23rd. It will be tried again next spring on the early crop 

 to note its effect upon cut worms in their relation to the young 

 plant. These late plants were free from maggot attack 

 (which was not bad on any of the late cabbage and cauli- 

 flower) and altho four out of the twenty-five plants showed 

 injury, possibly from the Paris green, the remainder made 

 a good showing and formed good heads. 



Bran, Glue and Hellebore: Hellebore substituted for the 

 Paris green in the above, and five plants treated June 23rd 

 with good results. 



Air Slaked Lime: Radishes — Dry lime dusted on plants, 

 and on ground close to plants. Applications May 22nd, May 

 28th, June 5th. On June 22nd, when these were ready for 

 market, they were quite free from worms. 



Milk of Lime: One half pound quick lime slaked in i gal. 

 water. 



On Cauliflower: Applications about base of plant May 

 23rd, May 28th, June 5th. Plants killed by maggots. 



On Cabbage : Same applications and same results as 

 above. Several killed by cut worms. 



Dipping in Milk of Lime: Dipped the roots of 30 cabbage 

 plants on May i8th before setting in solution i lb. lime to i 

 gal. water, and planted. On the same date 30 plants were 

 dipped in half that strength. In both cases the plants were in- 

 jured. This injury was particularly noticeable when the solu- 

 tion was I lb. to I gal. About 60 per cent of these plants sur- 

 vived the treatment, and were not affected by the maggots. 



Disturbing the Eggs by Stirring: On the supposition that 

 possibly disturbed eggs would not hatch, we had the soil close 

 to the stalks of 150 plants stirred with a pointed stick on May 

 15th, 17th, 23rd and June 4th. About five plants could be 

 treated in a minute. Like other experiments tried in this field, 

 where the fly was not abundant, there was no good oppor- 

 tunity to compare treated with untreated plants. References
