DEF

[A] fungal disease that attacks the leaflets, stems, petioles, pods and seeds of lentils.

CONT

Ascochyta Blight of Lentil. Symptoms appear on leaves, stems and pods as white to tan coloured spots, often with a darker margin. The centres of lesions are often speckled with tiny, black fruiting bodies(pycnidia) which contain the spores of the fungus. When the disease becomes severe, leaves may drop prematurely and shoots may be blighted. Dieback and flower and pod abortion are the main causes of yield loss.

DEF

Maladie fongique touchant les folioles, les tiges, les pétioles, les gousses et les graines de la lentille.

CONT

Ascochytose de la lentille. Les symptômes apparaissent sur les feuilles, les tiges et les gousses sous forme de taches blanches à chamois, souvent avec un contour plus foncé. Le centre des lésions est souvent tacheté à cause de la présence de petits organes fructifères noirs (pycnides) qui contiennent les spores du champignon. Quand la maladie s'aggrave, on constate une chute prématurée des feuilles et la brûlure des pousses. Le dépérissement et l'avortement des fleurs et des gousses sont les principales causes des pertes de rendement.

DEF

Any of many lung diseases caused by the inhalation of a variety of organic or inorganic dusts or chemical irritants, usually over a prolonged period of time.

CONT

The disease appears in different forms, depending on the type of dust you inhale. One of the most common forms is black lung disease, also known as miner's lung. It's caused by breathing in coal dust. Another is brown lung, which comes from working around dust from cotton or other fibers. Other types of dusts that can cause pneumoconiosis include silica and asbestos. Diacetyl, the compound used to give movie popcorn its buttery flavor, also can lead to the disease. This is known as popcorn lung.

This disease starts out as a black to purple leaf spot. As the disease progresses, the fungus works its way to the plant's base and attacks the roots and crown. Basal tissues near the ground become dark brown and rot. This stage is called melting out because the grass gradually thins and "melts out" the diseased area. The turf appears yellowish, thin and shabby with irregular patches of dead grass. When these areas are raked, the dead grass plants are easily removed.

DEF

An occupational disease of coal workers resulting from deposition of coal dust in the lungs.

OBS

Black lung disease is the common name for coal workers’ pneumoconiosis(CWP) or anthracosis, a lung disease of older workers in the coal industry, caused by inhalation, over many years, of small amounts of coal dust.

OBS

anthracosis : A histological term describing the accumulation of black pigment in lung tissue or in other organs. In the lung the accumulation often appears as macular lesions, usually in a centrilobular location, along the walls of bronchioles, but also along interlobular septa or in the subpleural space. This pigment is mainly composed of carbonaceous material and may originate from cigarette smoke(or other smoked drugs, such as crack cocaine), atmospheric pollution, residential exposure to wood(or biomass) smoke or occupational exposure to carbon-containing dusts, such as diesel exhaust, soot, fly ash, carbon black, graphite and coal. Thus a more or less marked degree of anthracosis may be found in nonsmoking urban residents from heavily polluted areas or in inhabitants(often females) of poor countries with a cold climate(so-called ’hut lung’). Anthracosis is only rarely associated with overt pulmonary disease, except after prolonged, heavy, usually occupational exposure, when the condition is preferably labelled as a pneumoconiosis, e. g. graphite pneumoconiosis(graphitosis) or coal workers pneumoconiosis. The latter pneumoconiosis is often called anthracosilicosis(particularly in continental Europe), because this pneumoconiosis has been considered to be caused predominantly by the silica content of coal dust. While this may be true in many instances, the use of anthracosilicosis to indicate coal worker's pneumoconiosis is probably not entirely appropriate, because the pathology of coal workers pneumoconiosis is different from that of silicosis.

Downy Mildew of Cabbage. Caused by the fungus Peronospora parasitica. Damage occurs mostly to young plants or to exposed leaves of heading plants.

CONT

The fungus causing downy mildew of cabbage also attacks other crucifers, such as cauliflower, collards, Chinese cabbage, Brussels sprouts, broccoli, kale, and kohlrabi... The first symptoms of downy mildew are the formation of black specks and yellow-brown spots on the upper leaf surface, accompanied by the development of a fluffy mold growth on the lower surface. Young leaves may fall off when infected, and on older leaves, the spots may coalesce, producing large, sunken, tan spots. The disease can attack young seedlings or plants that have already headed. On older cabbage plants, the disease produces dark, sunken spots, which may appear purplish, on the head or wrapper leaves.

Black Sigatoka is a leaf spot disease of banana that can cut a tree's fruit production in half. The fungal disease causes dark leaf area to turn yellow and brown... The fungus that causes black Sigatoka, Mycosphaerella fijiensis, is spread from tree to tree by wind, rain, and irrigation water.

CONT

[The] black leaf streak disease(popularly known as ’black Sigatoka’), caused by Mycosphaerella fijiensis, is the most widespread and important of three major species of leaf-spot diseases affecting banana and plantain.

OBS

The name black Sigatoka was given to the disease because it was first discovered... in the Sigatoka Valley of Fiji.

Yellow Sigatoka. The first symptom of the disease is the appearance of yellow-green specks in the lower surface of the third and fourth youngest open leaf. The specks elongate and expand into clearly visible brown streaks. As the streaks further increase in size, they become elliptical brown spots surrounded by a yellow halo that separate the spot from the normal green leaf tissue. When the spots become fully developed, the central areas turn gray, which eventually are surrounded by dark brown or black margin with yellow halo. The spots group together to form large areas of light brown, dried-up leaf tissues. This leads to premature dying of the leaves.

OBS

Symptoms of yellow Sigatoka ... typically develop more slowly than symptoms of black Sigatoka ...

OBS

Authors often use "Sigatoka disease" in reference to the "yellow Sigatoka disease" and will add "black" in front of "Sigatoka disease" if they don’t talk about the yellow one.

DEF

A usually asymptomatic form of pneumoconiosis caused by deposition of coal dust in the lungs [which] is present in most urban dwellers.

OBS

anthracosis : A histological term describing the accumulation of black pigment in lung tissue or in other organs. In the lung the accumulation often appears as macular lesions, usually in a centrilobular location, along the walls of bronchioles, but also along interlobular septa or in the subpleural space. This pigment is mainly composed of carbonaceous material and may originate from cigarette smoke(or other smoked drugs, such as crack cocaine), atmospheric pollution, residential exposure to wood(or biomass) smoke or occupational exposure to carbon-containing dusts, such as diesel exhaust, soot, fly ash, carbon black, graphite and coal. Thus a more or less marked degree of anthracosis may be found in nonsmoking urban residents from heavily polluted areas or in inhabitants(often females) of poor countries with a cold climate(so-called ’hut lung’). Anthracosis is only rarely associated with overt pulmonary disease, except after prolonged, heavy, usually occupational exposure, when the condition is preferably labelled as a pneumoconiosis, e. g. graphite pneumoconiosis(graphitosis) or coal workers pneumoconiosis. The latter pneumoconiosis is often called anthracosilicosis(particularly in continental Europe), because this pneumoconiosis has been considered to be caused predominantly by the silica content of coal dust. While this may be true in many instances, the use of anthracosilicosis to indicate coal worker's pneumoconiosis is probably not entirely appropriate, because the pathology of coal workers pneumoconiosis is different from that of silicosis.

OBS

Compare with "pneumoconiosis of coal workers" and "anthracosilicosis."

DOTHISTROMA NEEDLE BLIGHT caused by Dothistroma pini can infect all two or three needle pines, but only ponderosa and Austrian pines are highly susceptible. Early symptoms appear in late summer or early fall as deep green bands with a water-soaked appearance and as yellow or tan spots. The spots and bands turn brown to reddish-brown. The ends of infected needles gradually die and turn brown. Tiny black fruiting bodies develop near the infection band in late fall or the following spring. Infected needles drop prematurely. In the western United States, where the infected spots or bands are more red than in the Great Plains, this disease is called red band disease.

OBS

The disease usually is carried over from one crop to the next as black spores on the seed or as smut balls mixed with the seed. The sumut spores germinate when bunt-infested seed is sown in moist cool soils. The fungus infects the young seedlings, grows within them, and produces smut balls completely filled with black spores instead of kernels in the wheat head. The spores have the odor of stale fish.
