Well now, as compared with things of a fungous nature, the scab is a good deal like typhoid fever. The latter is insidious and it will destroy more—I take it there are more people die in the United States of typhoid fever every year than die of smallpox, ten to one. I haven't the statistics but I have that in mind, that it is a fact that they do, and yet there isn't half the fuss made about typhoid fever that there is about smallpox.
Now, that is so about the scab fungous disease. In Illinois, to illustrate, we have what is called the bitter rot fungus in the southern part of the state. If any one has the bitter rot they are scared to death, they think they are suffering untold misfortune. The bitter rot attacks the apples when nearly grown. The ground is covered with the rotted apples, and you can see them in the trees, but this little bit of scab fungus, they do not seem to notice that.
The reason is this, that scab comes from very minute spores that appear upon the apples in May or June, and as the summer advances they spread more and more. It depends, of course, upon the amount of moisture there is present, but it begins its work when the apples are very small. If it gets upon the stem of the apple it works around the stem and the apple drops off, and you have apples dropping from the time they are the size of peas until the very last of the fall, and while it looks in the month of June as if you are going to have a good crop of apples when it comes harvest time your crop has diminished greatly or to nothing, and you wonder where it has gone. With this scab fungus they just keep dropping, dropping, all through the season; whenever you have a little rain or wind these apples that are affected will drop off. You don't notice them very much because they go so gradually, one at a time or so, and you don't notice you are having any particular loss until it comes fall, and you find that your crop is very small.
That is why I say, you should wake up to the fact that it is necessary for you to spray if you are going to have perfect fruit and plenty of it—and I doubt not you could increase the amount of fruit you have in the State of Minnesota by ten times in one year by simply spraying your orchards thoroughly at the proper time with fungicide.
To do this, as I said, you must have a spraying outfit, individually or collectively, in your neighborhood, and if you get one individually you can take the contract to spray your neighbor's trees, if you wish, and get back enough to pay you for the outlay. If you have only a few trees and you have some one who understands it, you could just as well spray a few other orchards in the neighborhood and get your spraying done for nothing in that way, charging them enough to cover the cost and enough for some profit. That is done in some sections and is a very satisfactory way.
The only way, however, that I would do this, if I were you, would be to enter into a joint arrangement of not less than five years, because if you do it from year to year, if a man has good fruit one year, he may say, "I guess I don't want to go to that expense this year; I will drop that." You know how it is. If you make a contract for five years then you can make your plans accordingly and get your material and your spraying outfit and everything. I wouldn't trust to a one-year plan because they get "cold feet," as the saying is, after the first year, and perhaps they have not noticed any great advantage and they back out, but if they keep it up five years they wouldn't be without it.
In a small way it isn't necessary to have a high power, high pressure engine to do this spraying with. A good hand pump, as they make them now, has a very efficient force in applying this spray. It is not the force with which the spray material is applied that makes it effective, so much as it is the thoroughness with which it is done. You have to do a thorough job. In spraying you are providing insurance for your apple crop. That is just what it means, and not to spray is like doing without fire insurance on your buildings. You do that, not because you want fire, but you are doing it for protection, you are going to be on the safe side. You are doing like the darkey woman when she was about to be married. She had been working as cook, and the day came for her to be married. That morning she brought a roll of bills down to the boss. She said: "Mr. Johnson, I wish you would keep this money for me. I's gwine to be married." He said: "Is that so? But why do you come to me with this? I should think having a husband you would have him take care of it for you." She said: "Lord a' massy. Do you think I was gwine to have that money around the house wid dat strange nigger there? No, sir." (Laughter.)
That lady was taking the precaution of being on the safe side, and that is what we do when we spray our orchards, we are going to be safe.
There are a great many kinds of spraying materials. There is the bordeaux, one of our best fungicides, but we find in Illinois that it also, while it is a good fungicide, has the effect sometimes of burning the fruit if the weather conditions are just right. If you have pretty fair weather conditions up here and don't have too much rain, you probably would not get your fruit affected too much, and if you are not growing it for market it doesn't matter so much because all it does is to russet the fruit. It doesn't do any particular harm except when the scab fungus is especially bad, for then it does injure the foliage more or less. On the whole, in Illinois, we are using the lime-sulphur in preference to the bordeaux, and our commercial orchard growers there have completely abandoned the bordeaux except for bitter rot fungus or blotch fungus, which comes late in the season. The spray just before the bloom is a very important one for the scab fungus. After you can see the pink of the bloom on the trees as they begin to look pink, before the blossoms open, put on your lime-sulphur, or you can use bordeaux mixture at that time if you prefer it, without injury to your fruit.
