CHRYSANTHEMUM PESTS
The Rust; The two greatest enemies I of the chrysanthemum are the rust and the mining maggot that ruins the foliage. The rust is a fungoid disease, and may be treated on its first appearance with Bordeaux Powder or the simple home-made recipe of loz. sulphate of potassium in two gallons of water, sprayed over the foliage. Soft soap may be added at the rate of loz. per gallon. The Mining Maggot; The maggot works between the upper and under surface of the leaves, causing them to be veined with disfiguring lines. When the maggots are inside the leaves it is impossible to reach them and the only remedy is to squeeze the leaf between finger and thumb, killing the maggot or picking it out with the point of a sharp knife. It is far better to adopt preventive measures early in the season and spray the foliage with soot water or Black Leaf 40. This deters the fly which is responsible for laying her maggot eggs on the plants.
