Codling moth experiments


An excellent opportunity, of which I gladly took advantage was offered in my garden last summer for making tests and comparisons of certain remedies for the destruction of the larvae of the codling moth.

The diagram given below shows the row of Duchess trees, Nos. i to 13 inclusive, that were used in the experiment with their surroundings. At A are two Fameuse trees, at B two crabs, at C a Red Astrican and a tree of an unknown summer variety, at D two Roman Stems, and at E four Duchess. The two Fameuse trees, the Red Astrican and one or two of the Duchess trees bore light crops ; all the other trees were heavily loaded with fruit.
