I am enclosing some chrysanthoniuni leaves that are affected by a worm trouble, witli the idea of having you suj»j)ly me with a remedy. There are a number of leaves in this condition, but otherwise tlie jdants are in good form. W. A. R.—Ind. The chrysanthemum leaves submitted were affected by one of the leaf miners. One kind is bad on celery and many weeds are subject to this same pest. It is quite possible that your jjlants got this trouble, in the first place, from, some of the weeds in the neighborhood, which served as "host" jdants until the mums were growing. It is extremely difficult to stamp out this pest. Any application strong enough to penetrate the tissue of the leaf and kill the worm Will also kill the foliage. If the affected leaves are removed, as many as ])ossible, with- out injuring the remainder between the roots and tops, and the worms in these leaves are squeezed between the thumb and finger, thereby killing them, that is all one can do at this time. The best way to permanently get rid of the pest is to propagate next year with entirely new plants, which have been grown outdoors all summer and have received a slight freezing. In this way any diseases or j)ests that are on the plants will die. The slight frost will not damage the plants, which can then be brought into the greenhouses and propagated from. Chas. H. Tottv.
