This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1918 edition. Excerpt: ...the South there are from one to four or five broods each season. The last generation passes the winter in the chrysalid form among the old stalks and rubbish in the field. Injury.--This insect eats large, irregular holes in the leaves of cabbage, cauliflower, and related plants, and disfigures the heads of cabbage and cauliflower by deposits of excrement. Fig. 240.--Cabbage maggot: a, larva; b, pupa; c, adult female; d, head of male; e, antenna. Hair lines show actual sizes. (After Riley.) Control.--Cabbages and cauliflower are not susceptible to injury by Paris green; hence, Paris green may be used upon cabbages for this insect as strong as four or five pounds to fifty gallons of water without any injury whatever to the plant.

There is absolutely no danger to human beings on account of spraying cabbages. In the first place, little or none of the poison gets inside the head, and it has been demonstrated satisfactorily that a person would have to eat several bushels of sprayed cabbages at one sitting in order to obtain enough poison to cause serious results. This is self-evident. Cauliflower, when not headed out, may be sprayed with Paris green. These worms may also be reached by the use of poison bran mash, such as is prepared for cut-worms. White hellebore may be used as a poison, if timid gardeners fear Paris green. As additional measures children may be hired at a nominal sum to pick the caterpillars from the plants or to catch the white butterflies over a cabbage field. This pest is extensively parasitized.
