Time Required to Apply Bordeaux Mixture. 



Applj'ing Bordeaux mixture with a knapsack sprayer is hard 

 work; hence the amount of work done depends largely upon the 

 strength of the laborer. Experience gained from this experi- 

 ment and potato spraying experiments, shows that an active 

 man of average strength can make and apply from 125 to 150 

 gallons of Bordeaux mixture in a day of ten hours, using an 

 Eclipse knapsack sprayer with a single Yermorel nozzle. This 

 quantity can be increased to from 150 to 175 gallons per day by 

 using two nozzles, but when two nozzles are used it is necessary 

 to keep the pump handle working almost constantly, which 

 makes the work harder. In spraying cucumbers two nozzles can 

 be advantageously used in the later sprayings, provided the 

 laborer is strong and willing to work. 



Mr. Colyer's Opinion of the Experiment. 



The following statement from Mr. R. C. Colyer, of Woodbury, 

 L. I., N. Y,, on whose premises the experiment was made, ex- 

 plains itself. Mr. Colyer writes as follows: 



" The unsprayed vines were a failure — the blight affected them 

 before they commenced to pick. The pickles grew crooked and 

 pointed so that when they were counted about one-fourth of them 

 had to be thrown out and the balance were unsatisfactory at the 

 salting-house. The blight affected them so fatally that in about 

 two weeks they ceased picking. The sprayed vines grew vigor- 

 ously — the blight did not affect them apparently. The pickles 

 grew perfect and all were salable. The spraying preserved the 

 vines until they were killed by the frost, September 24th. The 

 vines were yielding fairly well when the frost came. This exper- 

 iment with Bordeaux mixture on the pickle vines was a success. 

 The crop from the vines sprayed was very profitable to me. The 

 blight was general last year, the main part of the crop being 

 destroyed about the middle of August. Very few farmers were 

 picking as late as September 1. The pickles that grew on these 

 vines preserved by the application of the Bordeaux mixture, sold 

 in Wallabout market, Brooklyn, at an average price of about
