This book was released on 2017-11-14 with total page 628 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Injurious and Beneficial, Insects of California Insect devastation costs the United States millions of dollars annu ally. California bears her full share, two millions being a reasonable estimate. Wise and timely application of well-known remedies would save much of this constant loss. Mr. E. O. Essig's signal success in the discovery and practice of control measures pointed him out as one fit to instruct the public as to the life histories of insects and the best methods to control their attacks. This led to the publication by the State Commission of Horticulture two years ago of Injurious and Beneficial Insects of California. Anticipating a great demand for the book, a very large edition was issued. These anticipa tions were greatly exceeded, and very soon, the edition was wholly exhausted. Commendation of the work was most hearty and reached the Commission from all countries, far and near. The call for another edition was loud and general. The Commission is greatly pleased to heed this request in the present enlarged and improved edition, which it feels sure will be very heartily welcomed.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Tomato Diseases in California Treatment - The control of this disease has been thoroughly worked out in Eastern States for potatoes, and the same methods will no doubt prove effective here. Treatment consists in Spraying with Bordeaux mixture; in climates with frequent rains in summer this is done several times at regular intervals, in order to keep the Vines well covered with Spray at all times; In California this would not be necessary. Spray ing should be regulated entirely by the rainfall. If there is no rain there is no danger whatever of winter blight, and no need of spraying.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Tomato Production in California Fusarium Wilt - This disease is caused by a fungus living in the soil, which enters the plant through the roots. When the disease once gets into a field, it spreads rapidly in succeeding years. The disease is said to occur in many parts of the state. It usually appears a few weeks after the beginning of hot weather, the lower leaves of aflected plants turn yellow and dry up (fig. The stems, if split open reveal dark brown streaks in the woody portion. The disease advances rapidly and kills the entire plant, or sometimes only one of the main branches. There is no true wilting of the plant, in the ordinary sense of the word, connected with this disease. The control is to grow resistant varieties, of which the Norton seems best at present, though Marvel, an early variety, and Norduke, a late shipping sort, may be desirable under some conditions. These varieties were recently developed by the U. S. Department of Agri culture. Snmmer Blight (western Blight). - This trouble/ occurs very generally in the state and is known by several names. The cause is unknown. The disease usually appears about mid-summer and may gradually involve many plants during the season. Affected plants stop growing, the margins of the leaves roll upward, and the under sides become purplish. The leaves and tips of the stem gradually dry up, and eventually the whole plant dies. No satisfactory control measure can yet be recommended. Root-knot. - This trouble is caused by nematodes - microscopic worms which infest the soil and which enter the roots of tomatoes and many other plants, causing the characteristic swelling of the roots. Affected plants appear stunted and yellowed, and die slowly. The trouble can always be recognized by pulling up the plants and inspecting the roots. Extreme caution should be exercised by growers to prevent the introduction of the disease on vegetable plants or seed potatoes shipped from other sections. When once introduced into the soil, nematodes are very. Difficult to eradicate. Flooding the land for two or three months, thorough drying out of the soil over' summer, summer fallow, and growing resistant crops for two years are prac tices that have been recommended. The small grains, the Iron variety of cowpea, and the velvet bean are some of the crops resistant to nematodes. One Should always be sure that the soil used for plant beds is free from nematodes, for infected beds are often responsible for infecting a field and spreading the trouble.

Download or read book California Cotton Insects Classic Reprint written by Gordon Lewis Smith and published by Forgotten Books. This book was released on 2018-09-10 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from California Cotton Insects The cotton dauber, Lygus hesperus Knight (fig. 1) is %2 inch long and one third as broad. The females are straw-colored, the males darker with red and brown markings on the wings, body, and appendages. The intensity of these colors varies considerably. The overwinter'ing males are nearly mahogany, the females reddish. The greenish-yellow, heart shaped mark between the bases of the wings helps to identify this insect on cotton. They are more readily observed during the cooler hours when they are less active. The long, slender mouth parts' are used to pierce the soft tissues and suck the sap, and the eggs are forced into this tissue with a. Saberlike ovipositor. A very small elliptical opening is left on the surface of the stem when an egg is deposited, through which the young nymph emerges after 7 to 12 days of incubation. There are five nymphal instars before the adult appears. The nymphs (fig. 1, B, C, and D) are pale green in color with red on the antennae; the third, -fourth, and fifth instars have circular black spots on the upper surface. Cotton growers sometimes mistake these for aphids, but they are much more active when disturbed, and the red antennae as well as the more slender bodies distinguish them from aphids.

Book excerpt: Excerpt from The Coccidae of California: A Descriptive List of the Different Scale Insects, Found in and Reported From California About sixteen years ago the State Board of Horticulture published a list of the Coccidse (scale insects) of California, giving some twenty-species found in the State. At that time comparatively little was known, by the residents of the State, about scale bugs or the amount of injury that could be caused by them; yet, to-day, there is no other single family of insects that is as important to the horticulturists of the world as are these minute creatures, and we can not know too much about them. As a group they are very unattractive to the average entomologist, and even more so to the average horticulturist, yet a knowledge of the species and the best known methods of combating their attacks is a very essential part of the education of every successful fruit-grower. Fruit-growing is a competitive business, and the successful grower must avail himself of every opportunity to gain knowledge that will be of assistance to him in his business; therefore, it has been deemed advisable to bring before his notice the following list of species occurring in California, with illustrations and short descriptions of the more important varieties, in order to enable the grower to recognize and distinguish between the destructive species and those that are not so destructive. Since the first list was published, and especially during the last few years, there has been a very active period among the growers, orchardists, nurserymen, and those having greenhouse interests, to gain a knowledge of scale insects. This activity has not been prompted by a love of the study of this particular branch of entomology, but purely as a business proposition, for these seemingly insignificant insects are capable of causing an enormous loss to the orchard, vineyard, nursery, or field in which they have gained a foothold. It must be remembered that each scale insect, after it has settled on the trunk, branch, or leaf of its particular host plant, virtually turns itself into an automatic pump and extracts the sap which is so vital to the life and growth of the tree. Usually the damage is done before the infestation is discovered, as many of our growers are absolutely without the slightest knowledge of scale insects.

Book excerpt: Excerpt from Investigations of Caterpillars Attacking Tomatoes in Northern California During 1939, Vol. 644 Amount and Persistence of Insecticide on Foliage - The frequency with which an insecticide must be used is influenced by the amount of toxic substance applied, its persistence upon the treated plants, and plant growth. In order to determine the persistence of the calcium arse nate and the cryolite used in the present experiments, samples of tomato leaves were taken from treated vines at six different times during the harvest season. Five leaves were removed at random from each of the four replications of a given treatment, placed in a paper bag, and brought to the laboratory with minimum disturbance.

This book was released on 2018-02-25 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The California Species of Mealy Bugs The systematic literature dealing with certain groups of the Coccidae or scale insects is extremely unsatisfactory, this condition being especially pronounced in the case of those groups commonly called the soft scales. The present author has stated in an earlier paper that of the nearly 100 species of mealy bugs thus far described from North America, including some 35 from California, not more than three or four are recognizable at all on the basis of the published descriptions if taken apart from their typical host and their type locality, nor at the time of the present writing does this statement need any extensive modification. A few species have been described since the statement was originally made and to some of these it may not apply, but so far as the species known at that time are concerned, the additional claim may safely be made that even under the optimum conditions cited, the identification of many of our species can not be accomplished with reasonable certainty.
