SUMMER MEETING. Ill 



the plums ; we have a large Imperial plum that seems to rot each year. 

 The Bordeaux mixture does not seem to help any. 



Mr. Stedman — This formula will do no good; you will have to 

 reach it by the Bordeaux mixture or something of the kind. This gouger 

 we were speaking of is very much like the curculio. 



Q. Cm you mix the arcenate oflead with this Bordeax mixture ? 



A. You can use the arcenate of lead just the same as if the 

 Bordeaux mixture was pure water. 



Mr. Murray — I think we have just about as many of the plum 

 gougers as we have of the curculio ; we have them both in my orchard 

 and I know them both. Here is a twig of that plum tree I sprayed 

 with the London purple, in the solution I spoke of a minute ago — one 

 pound of London purple, four pounds of lime and 50 gallons of water. 

 I am satisfied that the plum tree standing not over thirty feet from it 

 has not one-half of its fruit perfect, and I am sure you cannot find an 

 imperfect plum on this bunch of 26, I also tried it on other trees. 



Q. Those curculios that deposit their eggs early and those plums 

 that fall to the ground, will they have time to go through the process 

 of germination and come up and sting them again ? 



A. There is but one brood a year. 



Mr. Stedman — I would not advise any one to use London pur- 

 ple for the reason that it is the refuse of different dye-stuffs, and its 

 character varies ; if you should use it this year and be successful and 

 try it again next year you might ruin your trees, because you might 

 get it of a different strength or quality, and so I would not advise its 

 use, or if at all, only after it had been tested very carefully. 



Q. Are grapes stung by the same insect ? 



A. No, sir, by an entirely different insect. 



Mr. Haseltine — I would like to know if there is any mode of spray- 

 ing, or anything that has any effect on bitter rot ? 



Mr. Whitten — Bitter rot has been reduced somewhat by careful 

 spraying ; a number of people who have tried spraying for it have re- 

 ported a certain per cent of benefit from the spraying ; there is no 

 way of absolutely preventing or curing bitter rot. You can reduce it 

 somewhat. Bordeaux mixture has given the best results by spraying 

 early in the season. 



And then right through the ripening season to spray with potas- 

 sium sulphide we have found it quite effective. You will notice it 

 grows less and less each year under this treatment.
