Henderson's Worm-Killing Grass Food 



Henderson's Worm-Killing Grass Food not only stimulates the grass ojj 

 lawns, putting-greens, tenuis courts, croquet grounds, etc., into rich greiii 

 growth, but it quickly eliminates the earth or angle worms that burrow in the 

 turf in almost unbelievable quantities, causing the soil to become sticky, 

 sour and loosening it and the roots so that hot sun and dry weather cause 

 the grass to turn yellow and die out in spots. More lawn, troubles are trace- 

 able to earth worms than most people realize, and we advise all whose grass 

 is not as good as it should be to apply Henderson's Worm-Killing Grass Food 

 at the rate of Yi pound to a square yard and water in with a hose. The worms 

 will then almost immediately come to the surface and die. For putting-greens 

 it is invaluable, keeping them free from worm casts, level and true without the 

 trouble and expense of daily brushing and rolling. It is used by many Golf and 

 Country Clubs and on many private grounds in the United States, and all users 

 are gratified with the results. Henderson's Worm-Killing Grass Food is a non- 

 poisonous powder not injurious to animal or bird life. Its fertilizing properties, 

 while combined into a well-balanced grass food, are not so strong but that it 

 can safely be applied on grass according to directions.

Purfeck Chickweed Eliminator 



The Modern Method of 

 Destroying Chickweed 



Chickweed is one of the most 

 troublesome lawn and sports turf 

 weeds, because of its extreme per- 

 sistency. Mowing will not destroy 

 it and hand extermination is a long 

 tedious job. Even where the weeds 

 are pulled by hand they are not com- 

 pletely destroyed because in most 

 eases the roots are broken and the 

 portions remaining in the soil begin 

 to grow anew. 



Purfeck Chickweed Eliminator 

 is a concentrated solution which is 

 mixed with water and sprayed on the 

 plants. This solution kills only the 

 chickweed and does not injure the grass. 

 For lawns, the solution should not 

 be sprayed during the hot weather 

 but only in spring and fall. It takes 

 from a week to twelve days to com- 

 pletely destroy the chickweed. It is 

 recommended to use an extension rod 

 (described on 

 page 195) so 

 that the spray 

 may be ap- 

 plied from 

 about two to 

 three inches 

 away from the 

 plants.

Du Bay Seed Disinfectants 



Important Notice: 



Invigorates seedling 

 growth, produces 

 sturdier plants. 



The Bayer-Semesan Company has selected from the 



lines of seed disinfectants originated by Bayer and du 



Pont, to both of which it has succeeded the most efficient formulas for each class of 



seed treatment, and will market and advertise them under the trade names listed below. 



Instead of planting your seeds and fighting disease afterwards, you can now treat them first with one of the Du Bay- 

 Seed Disinfectants and prevent many harmful seed-borne diseases. These seed disinfectants are easily and quickly 

 applied to the seed before planting and, by controlling certain diseases that exist on the seed, result in better crops of 

 improved quality. 



Their use also makes possible earlier planting in the spring due to their protective action against certain disease 

 organisms. 



The amount of these seed disinfectants required is so small that the treatments are extremely economical to usu 



"Damping-Off". Seedlings grown from Semesan-treated seeds are more re- ■ 

 Nu-Green sistant to the costly "damping-off" fungi which so severely attack both seedlingi 



and cuttings. 



"Brown Patch". Semesan prevents and cures "Brown Patch," a disease of 



grasses that destroys the turf on golf greens, grass tennis courts, parks and estates. 



Disinfection of grass seed with Semesan will also aid in preventing "Brown Patch." 



Poison Not Mailable. Shipped by Express or Freight only. F.O.B. N. Y. 



A Grass Disinfectant for 

 Brown-Patch Prevention and 

 Control. Also stimulates growth 

 of grass.
