Sucking insects like plant lice are not destroyed by 

 poisons applied to the outside of the leaves, but must be 

 killed by something sponged over the insects themselves. 

 Nicotine sulfate, j ounce to i gallon of water with a little 

 soap, is one of the best remedies. Soap solution, made by 

 dissolving | pound of soap in 2 gallons of water, is often 

 used'. Carbolic acid emulsion, made by dissolving i pound 

 of soap in i gallon of boiling water and adding i pint of 

 crude carbohc acid, also will destroy insects. The solution 

 must be mixed thoroughly. Strong tobacco water may be 

 used also. 



For plant diseases like blight and mildew, buy a prepared 

 remedy called Bordeaux Mixture and spray the plants as 

 soon as you see a diseased part ; or powdered sulfur may 

 be dusted over them when the leaves are damp. Burn any 

 plant that has been destroyed by plant disease.
