Virginia Spraying Experiments. ■ 



In Virginia ithe past season, the writer, with the as- 

 sistance of Mr. Leslie Pierce, conducted experiments for 

 the control of apple diseases with these lime-sulphur prepa- 

 rations and the results confirm the above statements. The 

 experiments were made on the Albemarle Pippin at Gro- 

 zet, the Winesap, York Imperial and Ben Davis at Fish- 

 ersville, and the York Imperial and Ben Davis at Mt. 

 Jackson, Virginia. The self-boiled lime-sulphur, the home- 

 boiled lime-sulphur and the commercial lime-sulphur, as 

 well as Bordeaux mixture, were used on each .variety. 

 The self-boiled mixture was used in two strengths, 8-8-50 

 and 10-10-50, and the home-boiled solution at a strength 

 of 5 lbs. of sulphur and 2]/ 2 lbs. of lime to 50 gals, of 

 water. The commercial lime-sulphur solution was used 

 at the rate of \]/ 2 , 1^4, 2 and 2 x / 2 gals, to 50 of water. 

 Arsenate of lead at the rate of 2 lbs. to 50 gals, was used 

 with the self-boiled mixture, the home-boiled solutions and 

 the Bordeaux mixture. The commercial solution was used 

 vvith arsenate of lead at the rate of 2 lbs. to 50 gals., with 

 Paris green at the rate of 6 oz. to 50 gals, and without any 

 poison. In the Mt. Jackson orchard the trees were sprayed 

 first, as soon as the petals fell ; second, three or four 

 weeks after the petals fell ; and third, nine to ten weeks 

 after the petals fell. The Fishersville orchard, on account 

 of scab, received an additional application, which was 

 made just before the trees bloomed. The Crozet orchard, 

 which was composed of Albemarle Pippins, received the 

 same treatment as the Mt. Jackson, and a fourth applica- 

 tion three to four weeks after the third. 



Effect of the Sprays on the Foliage. 



One of the objects of these experiments was to deter- 

 mine the effect of the several lime-sulphur preparations in 

 combination with arsenicals on apple foliage. Notes were
