Use Poisons on These 



Poison sprays, poison mashes, or con- 

 tact sprays may be used to eradicate cer- 

 tain garden pests. Here are some of the 

 most common insects, together with the 

 poisons to use on each of them. 



Chewins' Insects. Insects that eat the 

 leaves and tender parts of the plants may 

 be controlled by spraying- the plants with 

 lead arsenate at the rate of 1 ounce (15 

 level teaspoons) to each gallon of water. 

 When applied to plants with smooth foli- 

 age, such as cabbage, it is necessary to 

 add about V2 ounce of common laundry 

 soap to every g-allon of spray to make it 

 spread and stick better. Instead of using 

 it as a spray, lead arsenate may be dusted 

 on the plants early in the morning- while 

 they are still wet with dew. When used 

 in this way it may be diluted with 3 to 5 

 times its weight of air-slaked lime or fine 

 dust. Lead arsenate is preferable to Paris 

 green because it remains on the foliage 

 longer, is not ^so likely to burn the leaves, 

 and is cheaper, especially since the war 

 has greatly increased the price of Paris 

 green. 



Be Careful of Poisons 



Lead arsenate, white arsenic, and 

 Paris green, recommended in this 

 circular, are deadly poisons, and care 

 should be taken to keep them away 

 from children and domestic animals. 

 Bean plants should not be sprayed 

 after the pods have formed, nor to- 

 matoes after the fruit is nearly full 

 grown. There is no danger of poi- 

 soning to the consumer from eating 

 sprayed cabbage because the cab- 

 bage head grows from the inside 

 and the outer leaves are removed 

 before cookinc:. The outer leaves, 

 however, may have enough poison on 

 them to kill stock.
