A NEW METHOD OF DESTROYING WOOLLY APHIS. 



M. A. Cadoret, of France/ has discovered a new method of destroying- 

 woolly aphis on fruit trees. It consists in painting the attacked parts 

 with a mixture composed of : 



Liiisped oil 7 Pounds 



White lead H pounds 



Wliite zinc 1 pourifj 



Turpentine 1 pound 



Boil together the first three f(jr ten minutes and allow to cool, after 

 which add the turpentine and apply with brush in spring and autumn. 



In many sections where large knots are produced by this pest, it might 

 be well to give this method a trial yet this year. — E. 0. Essig. 



THE ROSE APHIS. 



In the Review of Applied Entomology, Series A, Vol. I, Part 8, page 

 271, 1913, there is a review of some experiments on the rose aphis, con- 

 ducted by T. Peneau in France. He calls particular attention to the 

 destruction of the eggs in winter by painting the stems with lime or 

 with a mixture of quicklime 5 parts, sulphate of iron 3 parts, water 

 50 parts (all by weight). A mixture which he claims is better than 

 either of the above is called Melange de Balbiani, and is made as follows : 

 Dissolve 7 pounds of naphthaline in 5 pounds of coal tar ; add 24 pounds 

 of slaked lime ; gradually add water until there are 10 gallons of spray. 

 These materials are applied in June. 



It might be well to experiment with the last spray as a means of 

 destroying the eggs of the rosy and green apple aphids, which are so 

 serious in California. — E. 0. EssiG. 



THE WATSONVILLE APPLE SHOW. 



The exposition at Watsonville, October 6th to 14th, was a pronounced 

 success. The pageantry feature was strikingly attractive; the feature 

 exhibits most original, very ingenious and, like the pageants, must have 

 required days of hard work. These were in the hands of the school 

 children of the county, and the writer has rarely, if ever, seen anything 

 to equal them. The wholesome attractions other than the exhibits war- 

 ranted the exceptionally large attendance. 



A noticeable reform over the exhibit of last year was the omission of 

 carload lots. Is it not much more important to exhibit single boxes, 

 five- and ten-box displays, as these attract the attention of the small 

 grower and growers rather than of the dealers? 



Messrs. Rowe of Michigan and Olwell of Rogue River Valley, Oregon, 

 who acted with the writer as .judges at the Exposition, commented very 

 favorably upon the quality of the fruit. Mr. Rowe, who has acted as 

 judge at all of these Watsonville expositions, stated that there was a 

 marked improvement each year, which gives clear warrant to such 

 exhibitions, costly though they may be in time and money. 



Two peculiarities of this Apple Show are most interesting : One, the 

 splendid apples coming from our mountain counties where the altitude
