Mr. Graves (Wisconsin): Do you use your black leaf 40 in conjunction with your Bordeaux or lime-sulphur?
Mr. Ruggles: Yes, you can.
Mr. Graves: Doesn't it counteract the result?
Mr. Ruggles: No, it does not.
Mr. Stakman: I used this year lime-sulphur and black leaf 40 together.
Mr. Graves: You say you got the same results from black leaf 40 in that mixture?
Mr. Stakman: It killed the plant lice; that is all I wanted.
Mr. Graves: We had some experiences that indicated that black leaf counteracted the other results.
Mr. Stakman: Yes, sir, I think that has been the impression, but I think there have been some experiments more recently to show that the black leaf 40 can be used in conjunction with other sprays without counteracting their results.
Mr. Richardson: Did you ever know the plum pocket to come unless we had cold weather about the time of blossoming and lots of east wind?
