expanded, spray with Bordeaux (No. i b). When the fruit has set, 

 spray with Bordeaux (No. i b) and repeat this once or twice until the 

 fruit is mature. If insects are troublesome, use a combined fungi- 

 cide and insecticide (No. 21). 



MELON. See Cucumber. 



ONION. 



Smut. 



Infects young seedlings but not transplanted onions, or sets. 100 

 pounds sulfur thoroughly mixed with 50 pounds lime per acre, 

 applied with a seeder in drills, has proved beneficial ; also ground 

 lime drilled in with a fertilizer drill at the rate of 75 to 125 bushels 

 per acre, is helpful. The best results have been obtained with the 

 use of formalin, i pound (pint) to 30 gallons of water (1-240) or i 

 ounce to i gallon of water (1-128), thoroughly sprinkled over the 

 seeds before covering them. A drip attachment on the seeder, 

 treating two rows at once, is a cheap and efficient method of apply- 

 ing formalin. One gallon of formalin solution will treat about 400 

 feet of drill. 



Maggot. 



Apply carbolic acid emulsion around the base of the plants, when 

 these first appear, using enough to wet the ground well on all sides of 

 the stems; repeat three or four times at weekly intervals. 



Thrips. (Blight.) 



Spray very thoroughly with kerosene emulsion when the insects 

 first appear ; repeat as needed. 



OATS. 

 Smut. 



Place the seed in a sack and immerse in formalin, i pound (i pt.) 

 to 36 gallons of water, for ten minutes, after which spread out and 

 dry for two or three days. This has proved very successful in pre- 

 venting oat smut. 



PEA. 

 Pea Weevil. See Bean Weevil.
