Directions For Use 



SPRAYING. To control any insect by spray- 

 ing it is necessary to spray carefully and thor- 

 oughly. An extra strong solution will not make 

 up for careless application of the spray. 



Use a fine spray and high pressure when 

 possible. Direct the spray to the under 

 side of the leaves or the point affected by the 

 insects. Each insect must be hit by the spray 

 to be killed. 



FUMIGATING. Before fumigating a green- 

 house see that all ventilators are closed. The 

 plants should be well watered so that the air 

 is moist. Fumigate in the evening, if possible, 

 and allow the fumes to remain in the house all 

 night. 



Either Hall's Free Nicotine or Hall's Nico- 

 tine Fum.igator may be used with equally good 

 results. 



Hall's Free Nicotine may be vaporized by 

 heating over lamps, by applying to the steam 

 pipes, or by using special heaters made for this 

 purpose. 



Hall's Nicotine Fumigator — Fill the conical 

 dipper, press in gently, and empty the cone 

 thus formed on a tin plate. In order to give 

 the Nicotine fumes the best chance to rise and 

 spread, the cone should be at least 12 inches 

 above the floor. Distribute the cones about the 

 house at equal intervals. Light the cones at 

 the top with candle or torch. 



Cubic Feet in Greenhouse 



All fumigation is based Measure y^. 



on the number of cubic height here \. 

 feet in the house. To deter- 

 mine this for your green- 

 house, multiply the length 



by the width by the average >^ , 



height (the distance from , \. 



floor to roof halfway be- / ■ ^ 



tween the side and the | \ I 



gable ) . I ' I 



Flant-Lice or Aphids 



These are small greenish, brown or black 

 sucking insects found on the under sides of 

 leaves or around tender shoots. Spray with 

 Hall's Free Nicotine diluted with 600 parts of 

 water — equal to 1^ teaspoonfuls to the gallon. 

 Add one pound of soap to each 25 gallons of 

 spray. 



If fumigation is preferable, vaporize one-half 

 ounce (one tablespoonful) to each 3,000 cubic 

 feet of space; or use Hall's Nicotine Fumigator, 

 one cone to each 7,000 cubic feet. 



Chrysanthemum Midge 



This is a very destructive insect. Its pres- 

 ence is easily detected by the numerous swell- 

 ings or galls which it causes on the under sides 

 of the leaves. 



Consistent spraying or fumigation must be 

 followed to rid a house of this pest. 



Fumigate every night for at least six weeks, 

 using Hall's Nicotine Fumigator — one cone to 

 each 4,000 cubic feet. Fumigation must be set 

 off between 12 P. M and 2 A. M. 



If fumigation is not convenient, spray every 

 other day for four to six weeks. Use Hall's 

 Free Nicotine diluted with 800 parts of water 

 — 1 teaspoonful to the gallon.. Add a pound 

 of soap to each 20 gallons of spray. Be sure to 

 spray late in the afternoon. 



Rose Midge 



This is a very destructive insect. Its eggs 

 are deposited inside the rosebuds. The mag- 

 gots (larvae) hatch inside the bud and suck the 

 juices of the petals, causing the petals and 

 leaves to dry up and turn black. 



After about a week the larvae drop to the 

 ground and burrow in. When they emerge, 

 they are adult flies and immediately lay eggs 

 for the next generation. 



This pest may be controlled by covering the 

 soil with a layer of Hall's Tobacco Dust and 

 by fiunigating nightly for three to four weeks. 

 Use Hall's Nicotine Fumigator — one cone to 

 3,500 cubic feet. 



Greenhouse Thrips & Mealy Bugs 



Because these insects feed in concealed 

 places, it is difficult to spray them. Fumiga- 

 tion is effective. Proceed as for plant-lice. 



Chrysanthemum Leaf Miner 



Spray with Hall's Free Nicotine, using a di- 

 lution of one to 400 (two teaspoonfuls to one 

 gallon).
