CRIDDLE MIXTURE. 



Though this mixture is somewhat disagreeable to make and handle, 

 it is exceedingly cheap and affective, especially for grasshoppers. 



Frt'sh horse diuig GO pounds 



Common salt 2 pounds 



Paris green 1 pound 



The Paris green is mixed with enough water to form a paste and 

 is then stirred thoroughly into the horse dung with the salt. 



These poisoned baits are scattered about in fields infested with 

 grasshoppers, army and cutworms and various other destructive chew- 

 ing insects or they nmy be placed in advance of the oncoming hordes. 

 A very important thing in handling the poisoned baits is to see that 

 they are kept moistened all the time, as they become worthless when, 

 dry. To prevent this drying out the mixture should be put out in 

 small piles and occasionally moistened. They may also be placed under 

 boards or in the shade, while for cutworms and wireworms it is often 

 advisable to bury them in the ground.

Lime-sulphur is easily the most important insecticidal spray now 

 used and its fungicidal properties make it even more useful to the 

 orchardist. It is especially valuable for controlling scale insects and 

 fungi on deciduous fruit trees, though if properly weakened it may also 

 be used as a summer spray, particularly for the citrus and almond 

 spiders. 



Formerly lime-sulphur spray was a home-made product, but today the 

 commercially prepared product is so superior to the home-made mixtures 

 that the latter have almost ceased to exist. 



HOME-MADE LIME-SULPHUR. 



Formula. 



Lime 40 pounds 



Sulphur (flowers) 30 pounds 



Water to make 100 gallons 



Preparation. — Heat in a cooking barrel or vessel about one third of 

 the total quantity of water required. When the water is hot, add all 

 of the lime, and at once add all the sulphur, which should previously 

 have been made into a thick paste with water. After the lime is slaked, 

 another third of the water should be added, preferably hot, and 

 tlie cooking should be continued for an hour, when the final dilution 

 may be made, using either hot or cold water as is most convenient. 

 The boiling due to the slaking of lime thoroughly mixes the ingred-
