Paris green is often used in the dry form for dusting on plants. 
In this case it is better to dilute with some other material, such as flour, 
slaked lime, or pla'ster. 
A good proportion is: 
Paris green . . 1 pound 
Common flour, lime or plaster . 25 pounds 
The flour wdll prove better than the other materials, as it will not 
be distasteful to insects and will adhere better to foliage. 
When the Paris green is applied in a watery spray, the most com« 
mon strength is: 
Paris Green . 1 pound 
Water .160 gallons 
Lump lime . 2 pounds 
For stone fruits it is safer to use 200 gallons of water. Make the 
Paris green into a paste, then slake the lime in a small amount of water 
and add to the Paris green. Dilute until it can be strained into spray 
tank. Keep the liquid thoroughly stirred during application, as the 
Paris green settles out very quickly. 
3 . Poison Bran Mash 
The following poison bran mashes have been found quite effective 
in destroying grasshoppers in orchards and vineyards, and army worms 
and cutworms when abundant: 
White arsenic or Paris green . 1 pound 
Bran . 20 pounds 
Syrup . 2 quarts 
This formula has been used for a number of years, but Professor 
George A. Dean of Kansas has developed the following formula that 
is highly recommended: 
Paris green . 
Bran . 
Syrup (cheap) 
Water . 
Lemons . 
3 pounds 
50 pounds 
4 quarts 
5 gallons

Mix the Paris green and bran together while dry; dissolve the 
syrup in the water; squeeze the lemons into this and finely chop the 
peel and pulp and add them also; pour this mixture into the bran and 
Paris green, and stir so as to dampen the mash thoroughly. The lemons 
may be prepared by putting them through a meat grinder. Distribute 
the mixture broadcast in as fine particles as possible where the grass¬ 
hoppers are most abundant. The application should be made towards 
evening or early (between 4 and 7 o’clock) in the morning. From 3 to 
5 pounds of dry bran is usually sufficient for an acre of land. Never 
distribute in little piles. For army worms, distribute more freely just 
ahead of the line of march.
