what is coffee disease

Which of the following is major disease of coffee?

Coffee leaf rust is a fungus that has become one of the biggest threats to coffee around the world. It is present in almost every coffee-producing country, regardless of local environmental conditions.

What are the causes of coffee disease?

Coffee rust is a devasting disease caused by a rust fungus, Hemileia vastatrix. It can reduce coffee production from between 30% to 50%. Infestation levels vary depending on a variety of factors. These include an advantageous climate for the disease, the management measures adopted and the plant's level of resistance.

How do you treat coffee berry disease?

Remove old stems and strip off diseased berries to reduce sources of disease. Prune the coffee trees to increase flow of air through the foliage; this also enables them to be sprayed effectively. Spray fungicides at the onset of flowering for 5 months. Spray twice a month, on top of the foliage.

What is the name of the disease that is currently causing concern for coffee producers?

This means that a plantation can be affected negatively by coffee rust for years after it is first struck with it. Coffee rust was first detected 150 years ago in what is now known as Sri Lanka, McCook said. At the time, coffee was one of the area's largest exports. But coffee rust devastated their coffee production.

Can you get a disease from coffee?

The bottom line: A large body of evidence suggests that consumption of caffeinated coffee does not increase the risk of cardiovascular diseases and cancers.

Can coffee berries be eaten?

Coffee cherries are fruits, and yes, you can eat them. They even have a nice sweet flavor. But before you rush out to try them, there are good reasons these aren't a popular fruit. Unlike regular cherries and other fruits, coffee cherries haven't been grown to optimize the fruit flavor.

How do you heal a coffee plant?

Root Rot. Maintain moist soil and water when the top inch or so of soil has dried out. If your plant sits in water or the soil is too wet, the roots can rot and kill the plant. If you notice excess water or waterlogged soil, you can repot into well draining potting soil to prevent further damage.

What kills coffee plants?

One disease that coffee plants tend to get is “coffee rust”, a damaging fungal infection that will kill coffee plants if not caught early enough. Not only is it devastating to one plant, but it can also take out an entire plot of coffee plants.

What are the 4 enemies of coffee?

Your beans' greatest enemies are air, moisture, heat, and light. To preserve your beans' fresh roasted flavor as long as possible, store them in an opaque, air-tight container at room temperature. Coffee beans can be beautiful, but avoid clear canisters which will allow light to compromise the taste of your coffee.

Can coffee cause long term health problems?

Regular use of more than 600 mg of caffeine might cause the short-term effects listed above. Long-term effects at this level may include chronic insomnia, constant anxiety, depression, and stomach problems. It can also cause high blood pressure or make high blood pressure worse.

What bacteria is in coffee?

During coffee processing, lactic acid bacteria (LAB) from multiple ecosystems (water, native soil, air, and plant) find in the cherry pulp a rich environment for their development. They utilize pulp substrate as a source of carbon and nitrogen to produce significant amounts of lactic acid.

How do you stop coffee Diterpenes?

Diterpenes are super easy to avoid. All you have to do is brew your coffee through a paper filter. In one study that measured the amount of cafestol in a cup of coffee brewed this way, investigators found that just 0.15% of the cafestol present in the unbrewed coffee grinds passed through to the brewed cup.

What temperature does coffee grow in?

Basic requirements Coffee plants grow best in warm, humid environments. Arabica coffee varieties grow best at temperatures between 18 and 22°C (64–72°F), while Robusta coffee grows best in slightly warmer temperatures of 22–26°C (72–79°F). The plants do not tolerate cold and freezing temperatures will kill the leaves instantly.

Where did coffee rust originate?

History Origins and spread Coffee originates from high altitude regions of Ethiopia, Sudan and Kenya and the rust pathogen is believed to have originated from the same mountains. The earliest reports of the disease hail from the 1860s. It was reported first by a British explorer from regions of Kenya around Lake Victoria in 1861 from where it is believed to have spread to Asia and the Americas. Rust was first reported in the major coffee growing regions of Sri Lanka (then called Ceylon) in 1867 and the causal fungus was first fully described by the English mycologist Michael Joseph Berkeley and his collaborator Christopher Edmund Broome after an analysis of specimens of a “coffee leaf disease” collected by George H.K. Thwaites in Ceylon. Berkeley and Broome named the fungus Hemileia vastatrix, Hemileia referring to the half smooth characteristic of the spores and vastatrix for the devastating nature of the disease. It is unknown exactly how the rust reached Ceylon from Ethiopia but over the years that followed, the disease was recorded in India in 1870, Sumatra in 1876, Java in 1878, and the Philippines in 1889. During 1913 it crossed the African continent from Kenya to the Congo, where it was found in 1918, before spreading to West Africa, the Ivory Coast (1954), Liberia (1955), Nigeria (1962-63) and Angola (1966). The collapse of the coffee industry in Ceylon In the nineteenth century, Ceylon was one of the largest coffee producing regions in the world, responsible for the export of approximately 42 million kilos of coffee per year. In the 28 years following the arrival of rust, export ceased and production was reduced to less than 3 kg/year. It wasn’t until 1879 that the government of Ceylon set up a commission to investigate the crisis and the British government sent Harry Marshall Ward to the plantations. Ward’s work on the coffee rust fungus would establish him as one of the most important figures in the field of plant pathology. Ward was able to link the collapse of the coffee crop to the Hemileia vastatrix fungus and, identify characteristics of both the fungal spore and agricultural practices that caused such a catastrophic loss. Unfortunately the investigation came too late and the rust epidemic was too far advanced. Ward could do little other than document the complete collapse of the coffee crop, as has been recounted in many histories of the disease (Large, 1940, Carefoot and Sprott 1967, Money 2007). Ward’s observations however, would provide the crucial basis for the development of future control strategies, discussed below. Biology and ecology of coffee rust The collapse of the Sri Lankan coffee industry and Ward’s investigation of the agricultural practices being employed highlighted the problems created by planting coffee at such high densities. The proximity of the plants to one another created optimal conditions for rust transmission over short distances while the reduced genetic diversity resulting from the practice of monoculture meant that once the rust pathogen broke down the inherent host resistance, little could be done to prevent its spread. The pathogen, Hemileia vastatrix, evolved within the forest and adapted to the widely dispersed nature of the wild host by producing highly mobile spores that are capable of travelling large distances via wind currents, water splash and on the bodies of insects. The practice of removing native trees to plant coffee side by side, removed a natural barrier to the movement of the rust spores and helped compound the catastrophic crop losses witnessed in Ceylon. Rust transmission and infection Coffee leaf rust is an obligate parasite and is transmitted when urediniospores (spores produced from the brown-red rust pustules) disperse from one part of the plant to another, or to a new, uninfected plant. The spores are produced on the underside of the leaf from uredinia which make up part of the red/orange pustules on the undersides of the leaves. When the spores erupt, they enter the air current where they can travel a few centimeters to the next leaf, or hundreds of kilometers to another site (spores have been recorded travelling 1,000 m up in the high altitude air streams). The spores are also known to travel over shorter distances by rain-splash, which is a common way for plant pathogens to travel from leaf to leaf of the same tree. There are also documented cases of spores being transported to new sites by small insects such as Thrips and parasitoid wasps. When the spores reach a leaf, they attach to the surface using the spines on their rough side. In order for the spores to germinate, they require the presence of liquid water on the leaves and a temperature of 17 to 25°C (62.6 to 77°F), with 22°C (71.6°F) being optimal. Heavy rains can wash the spores from the leaves and prevent infection occurring. When conditions are favorable, the spores produce a long tubes known as germ tubes which move over the leaf searching for a stomata (tiny openings in the leaf surface where plants breathe and release water). The germ tubes produce appressoria (flattened fungal structures that produce ‘pegs’ to puncture through host tissues) on, or close to the stomata, from which infection hyphae grow and puncture the host cells. The entire infection process is completed in 24 to 48 hours and new urediniospores erupt from the stomatal openings after 10 to 14 days. One rust lesion will produce 4–6 spore crops over a 3–5 month period releasing 300–400,000 spores into the environment to repeat the process. The 2012 Coffee leaf rust epidemic In 2012 there was a major increase in coffee rust across ten Latin American and Caribbean countries. The disease became an epidemic and the resulting crop losses pushed coffee prices to an all time high amid concerns for supply. The reasons for the epidemic remain unclear but an emergency rust summit meeting in Guatemala in April 2013 compiled a long list of shortcomings. These included a lack of resources to control the rust, the dismissal of early warning signs, ineffective fungicide application techniques, lack of training, poor infrastructure and conflicting advice. In a keynote talk at the “Let’s Talk Roya” meeting (El Salvador, November 4th 2013), Dr Peter Baker, a senior scientist at CAB International, raised several key points regarding the epidemic including the proportional lack of investment in research and development in such a high value industry and the lack of investment in new varieties in key coffee producing countries such as Colombia.

What are the factors that affect caffeine?

Sensitivity to caffeine is largely determined by the activity of the CYP1A2 enzyme in the liver. The more active the CYP1A2, the less sensitive we are to caffeine. Several factors affect CYP1A2 activity: 13  1 Age: CYP1A2 activity tends to decrease with age, so older people tend to be more sensitive to caffeine 2 Sex: women tend to have lower CYP1A2 activity than men. 3 Oral contraceptive use and pregnancy: estrogens inhibit CYP1A2 activity and caffeine sensitivity increases. In general, pregnant women should try to limit or avoid caffeine. 4 Genetic makeup: Several gene variants have now been identified that affect CYP1A2 activity. While genetic testing can categorize your level of caffeine sensitivity, having formal testing is generally not necessary for you to know—at least generally speaking—whether or not you are very sensitive to caffeine. And if you are, it is likely that nobody needs to tell you to cut back.

What is coffee made of?

coffee. coffee, beverage brewed from the roasted and ground seeds of the tropical evergreen coffee plant of African origin. Coffee is one of the three most-popular beverages in the world (alongside water and tea) and one of the most-profitable international commodities.

How to tell if coffee leaves are rusting?

The symptoms of coffee rust include small, yellowish, oily spots on the upper leaf surface that expand into larger round spots that turn bright orange to red and finally brown with a yellow border. The rust pustules are powdery and orange-yellow on the underleaf surface. Later the pustules turn black. Rusted leaves drop so that affected trees are virtually denuded; such trees have significantly lower coffee yields and usually die within a few years.

How to control coffee rust?

Coffee rust can be partially controlled by the timely application of fungicide sprays during wet seasons. Plantations in some areas have been moved to higher and cooler altitudes, 1,800 to 2,100 metres (6,000 to 7,000 feet), at which the rust fungus has difficulty reproducing, though global warming is expected to further the spread of the disease into these areas. There is evidence that shade-grown coffees, which are not grown as monocultures, are somewhat less susceptible, as the agroforestry practice of mixing tree crops greatly slows the spread of the disease. Additionally, resistant varieties of Robusta coffee ( Coffea canefora) have been developed, but the beans are generally considered to be of lower quality than those of the vulnerable Arabica plants ( C. arabica ). One resistant variety, Lempira, was widely planted in Honduras but lost its resistance to the disease in 2017, resulting in crop losses in that country. No resistant varieties have shown to be impervious to all races of the fungus.

Does coffee affect liver enzymes?

While studies had been performed previously testing for coffee consumption and its association with liver enzyme levels, one study evaluated effect of coffee in patients with risk factors for chronic liver disease: consumption of greater than two alcoholic beverages daily, positive serum HBV antigen, positive serum HCV antibody, transferrin saturation > 50%, elevated BMI, and uncontrolled diabetics[17]. This study demonstrated relatively reduced levels of ALT amongst these higher risk groups.

Does coffee affect AST?

In numerous studies, it has been noted that coffee consumption has been associated with decreased levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT), gamma-glutamyltransferase (GGT), and alkaline phosphatase (ALP). One of the first studies to document consumption of coffee with relatively decreased GGT was in 1985 in the Tromsø Heart Study[8]. That same year, another study noted an inverse relationship between coffee consumption and AST and ALT levels amongst both Korean and Japanese immigrants[9]. These studies began an investigation into elucidating a more direct relationship between coffee and possible hepatoprotective properties. The Tromsø study looked at multiple beverages, notably including green tea. Since 1985 multiple other studies have been performed with similar findings when testing specifically for the possible effect of coffee consumption on liver disease.
