Mr. Stakman: Yes, a little; I have seen it mostly when there was cold weather, however, and as I said before it usually isn't so serious unless there is cold, wet weather.
Mr. Richardson: I settled out in Martin County, Minnesota, in 1866, and in all my experience I never saw plum pocket unless we had the right kind of cold weather at the time of the blossoming. I had my plums all killed and destroyed one year and never did anything for it, and when we had the right kind of weather I never had any trouble.
Mr. Stakman: When you have cold, wet weather, as I mentioned before, infection takes place much more rapidly than it does at other times. There is some evidence to show that the fungus lives in the twigs and that affected ones should be cut out.
Mr. Richardson: Yes, but these didn't bear any for four or five years, and when we got the right kind of weather I got good plums.
Mr. Norwood: My experience is something like this man's. I have had my plums killed off as many as five years with the plum pocket and then had a good crop of plums. I sprayed with lime-sulphur.
Mr. Stakman: When did you spray?
Mr. Norwood: I spray just before the buds open.
Mr. Stakman: The flower or leaf?
Mr. Norwood: Flower, and then I spray when the plums are well started, just before they begin to ripen.
Mr. Stakman: Were you spraying for the pocket or brown rot?
