Disease Management in Organic Seed Production
Climate change is triggering similar effects on the incidence and severity of disease for crops in agriculture and wild plants in natural communities. The complexity of natural ecosystems, however, generates a complex array of interactions between wild plants and pathogens in marked contrast to those generated in the structural and species simplicity of most agricultural crops. Understanding the different impacts of climate change on agricultural and natural ecosystems requires accounting for the specific interactions between an individual pathogen and its host s and their subsequent effects on the interplay between the host and other species in the community. Ultimately, progress will require looking past short-term fluctuations to multiyear trends to understand the nature and extent of plant and pathogen evolutionary adaptation and determine the fate of plants under future climate change.

Click here for a Chinese translation of this article pdf file, 1. Plant diseases have caused severe losses to humans in several ways. Starvation and uprooting of families resulted from the Irish famine caused by potato late blight caused by Phytophthora infestans. A valued resource was lost with the virtual elimination of the American chestnut by chestnut blight caused by Cryphonectria parasitica. And direct economic loss such as the estimated one billion dollars lost in one year to American corn growers from southern corn leaf blight caused by Cochliobolus maydis , anamorph Bipolaris maydis.
Diseases can have a significant effect on production of specialty seed crops. Seed growers must pay attention to diseases that affect the vegetative growth stage of the crop, as well as those that affect the reproductive growth stages flowering and seed formation. Some diseases, such as Verticillium wilt of spinach, become symptomatic only when the crop enters the reproductive stage; these diseases are more important to seed growers than to vegetable growers unless the vegetable crop also has a flowering stage, e. While vegetable growers are concerned primarily with the pathogens that affect marketable yield and quality, seed growers must also learn how to diagnose and manage seedborne pathogens and the microorganisms that affect seed quality.
Plant pathology also phytopathology is the scientific study of diseases in plants caused by pathogens infectious organisms and environmental conditions physiological factors. Not included are ectoparasites like insects , mites , vertebrate , or other pests that affect plant health by eating of plant tissues. Plant pathology also involves the study of pathogen identification, disease etiology, disease cycles, economic impact, plant disease epidemiology , plant disease resistance , how plant diseases affect humans and animals, pathosystem genetics, and management of plant diseases.
Бринкерхофф растерянно заморгал. - Да, сэр, - сказала Мидж. - Потому что Стратмор обошел систему Сквозь строй? - Фонтейн опустил глаза на компьютерную распечатку. - Да, - сказала .
Сколько там этих сироток? - спросила. Соши развела руками. Она села за терминал Джаббы и перепечатала все группы, а закончив, подбежала к Сьюзан. Все посмотрели на экран.
Скоростной карт фирмы Кенсингтон повернул за угол и остановился. Сзади, перпендикулярно туннелю, начинался коридор, едва освещаемый красными лампочками, вмонтированными в пол.
Раковина была очень грязной, но вода оказалась холодной, и это было приятно. Плеснув водой в глаза, Беккер ощутил, как стягиваются поры. Боль стала утихать, туман перед глазами постепенно таял.
- Маловероятно. Помимо всего прочего, в списке очередности указано, что это посторонний файл. Надо звонить Стратмору.
Дэвид… Слава Богу. Я думала, что потеряла. Он потер виски, подвинулся ближе к камере и притянул гибкий шланг микрофона ко рту. - Сьюзан. Она была потрясена.
