Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Insects Affecting Greenhouse Plants Every grower of plants under glass has, at some time or other, experienced losses owing to the presence of destructive insects. Roses, Chrysanthemums, carnations, primroses, ferns, snapdrag'ons, cucumbers, lettuce, and many other plants, are every year attacked by various kinds. Of leaf-eating, sucking or other insects, resulting in losses which amount, annually, to many thousands of dollars. Much of this loss may be prevented if growers. Will adopt the remedies which are recommended in this bulletin. When a plant is attacked, the grower should Observe how the insect feeds, as such fact will help materially in deciding upon the proper remedy to apply. Injurious insects may be divided, roughly, into two classes, by the nature of their mouth parts, namely, (1) biting insects which bite and chew their food, such as caterpillars, and (2) sucking insects which suck up their food by means of their beaks, such as the aphids, the true bugs, the scale insects, etc. If the insect is a biting one, a stomach poison, such as lea-d arsenate, is usually applicable, but if the species is a sucking one, such poisons would be useless because the insect would insert its. Beak through the poison and reach a safe feeding place beneath. Sucking insects, therefore, contact insecticides are recommended, such for instance as preparations containing nicotine. Certain insects. Such as. Aphids and white fly are best controlled by fumiga tion with a tobacco preparation or hydrocyanic acid gas. Boring or root destroy ing insects require a different treatment. In this bulletin information is included which should assist the grower to recognize the various kinds of insect pests with which his plants may become infested. The remedies for the insects discussed have bee-n found of value and if the grower will follow these carefully, he will undoubtedly keep the pests under control and thereby protect his plants. In addition to insects destructive in greenhouses, chapters are also included on animal pests, other than insect-s, and on useful or beneficial insects.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Greenhouse Pests: A Manual of Practice in the Control of Insects and Other Pests Attacking Ornamental Plants and Flowers Grown Under Glass in Illinois In the state as a whole, the total damage done by insects and other injurious forms of animal life is estimated at present to range from 10% to 25% of the value of all the flowers and Ornamentals grown under glass. Assuming 1570 as a fair average reduction, we can safely say that the annual crop would be worth more than it is now if the industry did not have to pay tribute to these pests. No crop is without its pests, and some have a dozen or more, so that the grower must be on his guard day and night through the grow ing season and even throughout, the year, in order to prevent all his profits from being literally eaten Up by one or another of these insidious enemies. Now the roots are attacked, now the stems and leaves, and now the flowers themselves. Sometimes only a few plants may be injured; again a whole crop may be wiped out. It is probably true that no single operation in the greenhouse yields as large returns as that which checks the depredations of insects, since any one of the major pests would be able to destroy a crop, commercially, before it could be matured if no control measures were applied.
