I now propose to give a list of recipes for insecticides and fungicides. I have tried each one before admitting it, and proved it to be efficacious. The various washes will be found to provide material for attacking all the major and many of the minor pests of the fruit garden. I may, however, point out that every practical grower has made one discovery, if no more - namely, that to give an insecticide or fungicide a chance of doing its work it must be brought into play in the first stage of the enemy's attack.
Several of the names given are coined ones. I am of opinion that they might be generally adopted with advantage.
