Spraying for the Destruction of Insects and Fungous Pests. 



Farmers, fruit growers and gardeners are coming more and more 

 to see the necessity of spraying tht ir crops to protect them from 

 insects and fungous pests, and as a rule those most successful in the 

 above lines practice spraying systematically and have as complete 

 equipment for this work as for the work of cultivation. 



The results of spraying the past season have shown many inter- 

 esting features and have led to some slight changes in the spraying 

 calendar for 1899 accompanying this paper. 



Many kinds of pumps and nozzles are in use, and some new 

 features have been introduced, the most important of which perhaps, 

 is the combined kerosene and water sprayer (kerosprayer). These 

 pumps are made with two cylinders, one for the water and the other 

 for the kerosene. These are worked by the same lever or handle, 

 the kerosene being forced into the hose with the water and distrib- 

 uted from the same nozzle in a very fine mixed spray. The pump 

 can be so regulated that 5, 10, 20, 25 and even 50% of kerosene 

 may be used. With these pumps the kerosene may be used with the 

 copper sulfate solution or the Bordeaux mixture, though with the 

 latter it has not given as satisfactory results as with the former. 

 Whatever the kind of pump purchased it is important that it be used 

 carefully, that the spraying material, if containing coarse particles, 

 be carefully strained before use, that all parts be kept well oiled and 

 after using, that the pump be cleaned by pumping sufficient water 

 through it to clear it of corroding materials. 



Good judgment and considerable mechanical 8kill must be exer- 

 cised to get the best results with any complicated machine, and only
