Email: li-yuan. The spatial spread of dark leaf spot caused by Alternaria brassicicola on Chinese cabbage was characterised over 2 years. The study was conducted in 2 field trials using ordinary runs, mapping, spatial autocorrelation, and 2-dimensional distance class analyses. Diseased plants were generally clustered and cluster orientation coincided with the line of inoculation. Disease spread was greater within than across rows. Core cluster size generally increased with disease incidence.

An introduction to plant disease epidemiology

Metrics details. The severity of plant diseases, traditionally the proportion of the plant tissue exhibiting symptoms, is a key quantitative variable to know for many diseases and is prone to error. Good quality disease severity data should be accurate close to the true value. Earliest quantification of disease severity was by visual estimates. Sensor-based image analysis including visible spectrum and hyperspectral and multispectral sensors are established technologies that promise to substitute, or complement visual ratings.

Plant disease forecasting is a management system used to predict the occurrence or change in severity of plant diseases. At the field scale, these systems are used by growers to make economic decisions about disease treatments for control. Often the systems ask the grower a series of questions about the susceptibility of the host crop , and incorporate current and forecast weather conditions to make a recommendation. Typically a recommendation is made about whether disease treatment is necessary or not. Usually treatment is a pesticide application. Forecasting systems are based on assumptions about the pathogen's interactions with the host and environment, the disease triangle.

АНБ покупает все, что ему требуется. Дрожа от нетерпения, Сьюзан вылетела в Вашингтон. В международном аэропорту Далласа девушку встретил шофер АНБ, доставивший ее в Форт-Мид. В тот год аналогичное приглашение получили еще сорок кандидатов.

 - Значит, тебе известно про Цифровую крепость. А я-то думал, что ты будешь это отрицать. - Подите к черту. - Очень остроумно. - Вы болван, Стратмор, - сказал Хейл, сплюнув.

Беккер встревожился: - Так кольца у вас. - Боже мой, конечно. Беккер ощутил тупую боль в желудке. - У кого же .

Упав, он устроил замыкание основного электропитания шифровалки. Но еще более страшной ей показалась другая фигура, прятавшаяся в тени, где-то в середине длинной лестницы. Ошибиться было невозможно.

Сверху хлестала вода, прямо как во время полночного шторма. Стратмор откинул голову назад, словно давая каплям возможность смыть с него вину. Я из тех, кто добивается своей цели. Стратмор наклонился и, зачерпнув воды, смыл со своих рук частицы плоти Чатрукьяна.
