 aid to some customers. 



Common Insect and Fungous Disease Cures 



BORDEAUX MIXTURE 



Bordeaux is used for a great many different kinds of plant diseases, as may be seen from the above 

 table. It is especially valuable in the control of mildew and fungous diseases on all vine plants, such 

 as muskmelon, cucumber and watermelon. It is also used extensively on tomatoes and beans. The 

 quantities may be varied according to the strength desired, but on most vegetable plants the 5-5-50 

 formula is most suitable. Five pounds of blue vitriol, or bluestone, is dissolved in water, and five 

 pounds of fresh hme is slaked in a separate vessel. Then the blue vitriol and slaked hme should be 

 added to sufficient water to fill a fifty-gallon barrel. This mixture should be used promptly as it loses 

 its effect if allowed to stand, but the blue vitriol may be dissolved beforehand. 



Forms of Tobacco Used as Insecticides 



Tobacco has been found to be one of the best insecticides. It is used very commonly in green- 

 houses but can also be highly recommended for destroying the common aphis which appears on nearly 

 all vegetable plants. In controlling the aphis it is important to spray so that the solution reaches the 

 under side of the leaves, as this is where the aphis works. The most common and effective forms of 

 tobacco are, "Tobaccoine," "Black-Leaf 40" and "Nicotine," which are used very successfully. These 

 preparations come with special instructions as to their strength and how they should be diluted.
