It is caused by the bacterium Erwinia amylovora. This organism was one of the first plant pathogenic bacteria to be extensively investigated, and has become a model for study by bacteriologists in the development of their subject. Written by leading research workers from the USA, Europe and New Zealand, this book is the first comprehensive volume for twenty years to address this subject.

For pears, cultivar choices are more limited because superior horticultural traits e. In recent years, fire blight has become more common in apples because the spectrum of cultivars grown commercially has expanded and shifted toward those with greater susceptibility to the disease e. With this shift has come the recognition that popular dwarfing rootstocks for apple, M.

Dwarfing rootstocks with resistance to fire blight are being developed and commercialized e. Many ornamental cultivars also show high levels of fire blight resistance. Vigilant sanitation through the removal of expanding and overwintering cankers is essential for control of fire blight in susceptible cultivars. Removal of overwintering "holdover" cankers is accomplished by inspecting and pruning trees during the winter.

Prevention of blossom infection is important in fire blight management because infections initiated in flowers are destructive and because the pathogen cells originating from floral infections provide much of the inoculum for secondary phases of the disease, including the infection of shoots, fruits, and rootstocks. Management actions to suppress blossom blight target the floral epiphytic phase.

Sprays of antibiotics, streptomycin, oxytetracycline or kasugamycin, have effectively suppressed blossom infection in commercial orchards Figure Copper compounds also are effective but applications are commonly limited to the pre-bloom period because copper ions in solution can be phytotoxic to the skin of young fruits.

Non-pathogenic, microbial epiphytes sprayed onto flowers can preemptively suppress fire blight by colonizing the niche stigmatic surface used by E. The bacterium Pseudomonas fluorescens strain A, is registered and sold commercially for this purpose BlightBan A as is the yeast, Aureobasidium pullulans Blossom Protect. In summer, established infections are controlled principally by pruning.

Effective control through pruning requires that cuts are made cm 8 to 12 inches below the visible end of the expanding canker Figure 13 and that between cuts the pruning tools are disinfested with a bleach or alcohol solution to prevent cut-to-cut transmission. Repeated trips through an orchard are necessary, as some as infections are invariably missed and others become visible at later times Figure Prunings harboring the pathogen are usually destroyed by burning Figure In severely affected orchards, cultural practices that slow the growth rate of the tree will also slow the rate of canker development.

This includes withholding irrigation water, nitrogen fertilizer, and cultivation. Similarly, practices that reduce tree wounding and bacterial movement can reduce secondary infection. This includes controlling insects such as plant bugs and psylla, limiting use of limb spreaders in young orchards, and avoiding the use overhead sprinklers. Chemicals such as streptomycin or copper can suppress trauma blight if applied immediately after a hailstorm. These hosts include hawthorn, serviceberry, and mountain ash. Early European settlers introduced apple and pear to North America.

The first report of fire blight as a disease of apple and pear occurred in , in the Hudson Valley of New York. In California, the disease was first reported in Early 19th and 20th century horticultural texts and bulletins recognized fire blight as a serious disease of pear, provided descriptions of symptoms, and outlined pruning practices for control Figure Nonetheless, in the eastern United States, fire blight proved to be destructively epidemic on pear, limiting the cultivation of this host.

Even today, the threat of fire blight restricts commercial production of pear to semi-arid, desert areas west of the Rocky Mountains. Koch's postulates for E. Arthur in , but the genesis of the concept that bacteria can be plant pathogens required the contributions of many scientists notably T. Burrill and growers over a period extending from to In the late 's, M. Waite linked blossom infection to the movement of the pathogen from flower-to-flower by pollinating insects. During the 20th century, introductions of infested plant material served to establish E.

In , fire blight was first observed in the Po River Valley of northern Italy, which is the largest pear production area in the world. Since , the Italian government has destroyed , pear trees in an attempt to eradicate E. Recently, fire blight has spread eastward from the Middle East to the northern Himalayan foothills of central Asia Kazakhstan, Kyrgyzstan , which is the center of origin for Malus apple spp.

Introduction The Gram-negative enterobacterium Erwinia amylovora is a plant pathogen that causes fire blight, a devastating necrotic disease forming a major threat to pome fruit and other economically relevant species belonging to the Rosacea family 1.
