Corn Eyespot Disease Research Paper

In Industrial Corn, the origin of Zea mays is from a sexual transmutation from the “mother corn,” teosinte. There is also a mention of the nitrogen cycle; when there is too much fertilizer added to crops, it could end in algae blooms and the death of fish in oceans. It discusses ecology and the relationship organisms have by the food chain. The corn is given fertilizer, then the cow eats the fertilized corn as well as take antibiotics, then someone consumes the cow. That means that the quaternary consumer consumed some fertilizer as well as the antibiotics the cow was given. In the Pastoral Grass section, grass’ roots have a special structure that helps the plant as a whole. Grass has a deep root system and ground- hugging crown to help withstand grating and fire (129). The symbiotic relationships of the mycorrizal fungi and roots are also

Many alterations have been applied to the area that corn is grown in. The main biome that corn is grown would be grasslands. Grasslands are an extremely important biome for producing food, it was shown that approximately 90% of the food produced today contains at least one of the fifteen species that are grown in grasslands. Unfortunately, for there to be enough space for corn to be grown and harvested, native grasses must be cleared, therefore having a devastating impact on the biome. Corn is known to be the most thirsty crop to be grown, taking up almost 7,000 to 8,000 gallons of water, draining countries, that don't receive as much rain, of their groundwater. Another impact on the environment of corn production would be the excessive use of fertilizers, this is due to the little nutrients returned back to the soil. As corn is mainly used for consumption, very little plant

Corn now a days has a very crucial and important part in our every days lives. It is the second most abundant grain developed for human utilization and is very versatile. Corn has various significances in our food, bio fuel and its medical advantages from the ancient time. The benefits of corn in terms of health and nutritional value is that it contains many vitamins such as the various B-complexes which is

At this point you must be wondering, whats the issue with corn? Frist let me point out when I say corn, I am not speaking of sweet corn that you eat a bowl of for dinner. We are talking about field corn, which is primarily grown to fed animals, that we then eat. The problem is with feeding animals field corn. Here 's the problem with feeding animals (particularly cows) field corn: animals are not supposed to eat corn!!!! As a result we have meat products that are wreaking havoc on our health. First, understand cows are meant to eat grass and other foraged materials. Cows are not supposed to eat corn, when they do a plethora of things happen. The first is that it makes them sick. Cows fed corn become bloated, are more susceptible to liver abscesses, and e.coli. Also, because Corn is high in phosphorous and low in calcium which is a recipe for kidney stones. You must also understand to combat all the damage the corn does to cow, farmers then pump their animals full of drugs to

Keeping in mind your answer to the previous question, what do you believe caused the corn plants to wilt and eventually die?

The start of our corn epidemic started when Christopher Columbus was introduced to it by the Native Americans. He took the corn and spread it around and now corn is the number one most widely planted crop in the world. Pollan said, “One need look no further than the $190 billion farm bill President Bush signed last month to wonder whose interests

The area’s cropland has, for a long time, been suited for the growth of durum wheat. However, because of the increase in rainfall, corn crops are being more apt to grow in the state’s terrain.

se that is endemic to the southwest United States (California, Arizona, Utah, Texas, Nevada, and New Mexico), Mexico, Central America, and South America [1]. Disease infection results from inhaling the spores from soil fungus Coccidioides immitis or Coccidioides posadasii [1]. The two fungi are located in separate regional locations, however, studies have shown that they are relatively identical and manifest the disease in the same way. Calling home in arid, desert areas, Coccidioidomycosis spores are found in lower elevations, 4 inches or more under sandy soil. They are endemic in areas with less than 20 inches of rain per year [1]. The most common opportunity to become infected is when the soil is disrupted by construction, entertainment

According to Diamond 2011, the increasing population and environmental problems caused civil unrest and warfare, where one of the signs of warfare was cannibalism. Low rainfall made a rainfall-fed dryland agriculture and irrigation impossible. A drought that lasted more then three years would have been fatal, because people could store corn for only 2 years after which it was too rotten or infested to eat. During the drought in 1670s, many people starved to death, and some people killed each

One problem with the fields this year was grass tetany, because of this rapid growing grass three cows died. More deaths include 3.8% death loss in ewes. These deaths usually are due to foot rot. Farmers have worked on killing bacteria and strengthening the hoofs of ewes.

Cotton/Texas root rot. Cotton root rot disease is one of the most destructive and difficult to control fungal diseases that can attack more than 2,000 broadleaf plant species. Cotton growers face the threat of significant crop damage to seedlings and potential devastation near maturity.

Only a few companies and crops are the sources of most products, creating an illusion of diversity. Many products are simply clever rearrangements of corn. 100 years ago, a farmer in America could grow 20 bushels of corn per acre. Now, they can grow 200 bushels per acre because of fertilizers and pesticides. In the United States today, 30% of our land base is being planted to corn. The biggest advance in recent years is high fructose corn syrup. Corn is the main component in feed ingredients and is even fed to fish. Cheap corn allows the price of meat to decrease. A result of feeding cattle corn and poor sanitation is the mutation of E. Coli with a strain called E. Coli 0157:H7.

Corn is most attractive to corn earworm adults during the silking stage (Johnson et al. 1975). Ovipostion generally occurs on the leaf hairs and the silks (Lingren et al. 1982). This process occurs during the reproductive stage in corn and may range from several day to several weeks. Due to the high value of sweet corn, multiple insecticide applications (12 to 40 insecticide applications) for corn earworm are economically viable. However, the value of field corn is considerably lower (Rector et al. 2002).

Now say this crop began to grow outside of where it was intended. Possibly the seeds spread to somewhere unintended. Now we have a super crop that is beginning to invade different parts of the already functional ecosystem in the surrounding area. These super crops would begin to take over the already existing species of corn, possibly wiping out the indigenous variety completely.

Environmental factor-The disease is seen throughout the year, but higher incidence is reported during rainy season and increased fly breeding in June-September, because the disease is spread mainly due to flies. Social factor-Drinking water or milk and food contaminated by intestinal contents of the patients or carriers or by flies which often transmit the disease. Eating unwashed and uncooked vegetables are good source of infection.
