Leaf Spot Tree Disease Prevention and Control

Leaf infections called leafspots are caused by a variety of fungi and some bacteria on many trees. An especially harmful version of this disease is called anthracnose which attacks many tree species including dogwood  and sycamore. Positive identification usually requires laboratory diagnosis. Symptoms of Leaf Spot Disease LA leaf spot disease creates spots on foliage. The spots will vary in size and color depending on the plant, the organism involved and the stage of development. Spots are most often brownish but may be tan or black. Concentric rings or a dark margin around the spot may be present. Over time the spots may combine to enlarge and form blotches. Spots or blotches that are angular and located around the veins are generally referred to as anthracnose. Leaves may yellow and drop prematurely. Prevention Good tree care is sufficient for prevention. Avoid crowding plantings too closely. Thin out branches to open up the tree crown, but dont top or dehorn. Rake up leaves in fall and bury or compost them. Plant different kinds of trees into the  mixture. Fertilize trees in the spring with a complete fertilizer. Water trees deeply during dry spells.   Control Use fungicides only when necessary. They MUST be applied prior to buildup of disease to effectively control leafspotting fungi. If severe leafspotting and/or defoliation occurs for several years, chemical control is probably necessary, but the leaf spot variety should be identified first. You can submit samples to your county agent for identification. The timing of protecting fungicide sprays is critical and varies for different fungi. Correct timing is a key to effective chemical control.

Enron Of The Sarbanes Oxley Act Essay - 1358 Words

Enron was a U.S. based energy-trading company. At its height of operation in the early part of 2001, it was booking revenues of about $140 billion (Enron Ethics). At the end of 2001 it declared bankruptcy. The Enron bankruptcy was the largest corporate economic failure at that time, and still remains an example of how corrupt practices magnify in the long run. What led to Enron’s failure was primarily a lack of ethics, and poor accounting practices. This scandal was one of the reasons that new regulations were passed for financial reporting standards, the Sarbanes-Oxley Act was passed in 2002 as a means of stopping such a collapse in the future. According to the movie, Enron: The Smartest Guys in the Room, Kenneth Lay was no stranger to corporate scandal. In 1987 the president of the Valhalla office in New York, Louis Borget, was found out to be making risking trades, destroying trade documents, and keeping two sets of accounting books. He was not fired by Lay after Lay was in formed of the wrongdoing, but later convicted and sent to jail. Jeff Skilling was hired in 1990, and decided to change Enron’s accounting method to mark-to-market accounting. This allowed them to book assets and liabilities at their fair value based on the current market price. This method was approved by the Securities and Exchange Commission and signed off on by Arthur Anderson, Enron’s accounting firm.

Demand And Supply Of Certain Resources In Australia

Question: Describe about the Demand And Supply Of Certain Resources In Australia. Answer: Introduction Demand and supply remain two fundamental techniques used in the analysis of micro economics. Demand describes the much a given quantity of a commodity is desired and bought by a consumer at a particular level of price. Supply describes the much of a quantity of a commodity a market can offer for sale at specific level of price. Demand and supply of any given commodity anchors varying variables or factors. The demand for commodity X is based on the price of that commodity (Px), price of the associated commodities, income of the consumer, quantity of consumers or the population, preferences and taste of the buyer. The supply for commodity X anchors the price of that commodity (Px), cost of production, price of inputs, and future anticipation regarding price levels. This paper discusses the mechanisms of demand and supply in microeconomic examination as a framework to help discuss the demand and supply of some resources in Australia alongside other factors other than price that determine demand and supply of such resources. Discussion (i) Mechanism of Demand and Supply Ceteris paribus all other determinants of demand of a resource, an increase in price leads to a decrease in demand, and a decrease in price hikes the demand. Simply put, a negative relationship exist between the quantity demand and the price. Conversely, Ceteris paribus all the determinants of supply of a resource, a jump in price upsurges the supply and a declined price downscales the supply. Put in another word, a positive correlation describes the relationship between price and quantity supplied (Delgado 2003). Where economic forces of demand and supply of a market can freely operate, equilibrium market demand at equilibrium market price follows at a point of intersection of demand and supply curve (demand=supply). Thus, the forces of demand and supply are determinants of market price in case of a free market economy where government interventions is curtailed. The illustration is drawn below graphically: In case of excess demand in the economy, the level of price will hike and with the rise in the level of price, suppliers will upsurge the supply, to meet the demand at the level of equilibrium show by point E above. (ii) Factors other than Price Determining Demand and Supply When other determinants of demand with an exemption of its own price fluctuate, the demand curve shifts upwards or downwards depending on the direction of the underlying fluctuation. For instance, where income of a person rises, then at the same level of price, the demand will upsurge with its curve shifting upwards. However, when the income downscales, then the demand will decline leading to downward shift in demand curve as illustrated in figure 2 below. Where other determinants of supply with an exception of its own price, alter, then the supply curve will shift outwards or inwards concurrently with the price level. For instance, when the production cost of product rises, then the supply will decline (Power, Sohal and Rahman 2001). The supply curve will then shift downwards. However, if the cost of production declines, then the supply will hike thereby shifting the supply curve outwards as indicated in figure 3 below. Based on the above examination of the mechanism of demand and supply, the demand and supply of certain resources (agricultural, mining and human) in Australia can be effectively performed in the subsequent subsection. (iii) Analyzing demand and supply of certain resources in Australian Market There are different resources in Australian market. These resource include mining, agricultural, human resource to mention a few. The demand-supply analysis for these resources remain more or less the same. Nonetheless, slight distinctions have been acknowledged between the two analyses. It should, however, be recognized that the analysis is same with agricultural resources. However, for mining and human resources, the analysis of demand and supply is distinct saves economic exogenous factors. These variables bring varying outcomes in demand and supply analysis of a range of economic resources. In the Eastern Australian Gas Market, for instance, asymmetry of alternatives exist in demand-supply analysis. The demand for this Australian Gas Market remained moderately low before 1990s. This was due to the pressure exerted by the international market rather than the price levels of the gas. Because of the vast scale export development from 1990s, the demand and supply of the Gas market have surged throughout the phase of time (Pearson, Pindyck and Rubinfeld 2005). Presently, taking into account, Bowen Surat gas fields case, it is evident that in the coming dozen years, the Liquefied Natural Gas supply from this particular field was completely missing for the local market despite the lack of a conventional rationale for the decline in LNGs supply. This scenario happened fully because of an external factors (McTaggart, Findlay and Parkin 2012). For these dozen years, the entire gases generated in this field remained completely contracted to Liquefied Natural Gas export. Despite the availability of sufficient gas in the eastern reserve potential of meeting the local supply supported by lack of demand zone shortage, a deficit supply of gases existed in the market. Focusing attention on the mechanism of demand and supply of human resources in the country, it can be seen clearly that the human resource demand in the market exceeds that of supply of skilled workforce. This scenario empties into an upsurge in the level of wage of the employees. Heightened supply is unable to meet the demand in spite of this hiked wage-level. This is because there is insufficiency of skilled workers in the Australian market. Conclusion Based on the analysis presented above, it is rational to conclude that the demand and supply of a given resource in Australia, not only relies on the level of the price for the commodity, but also, on certain exogenous as well as endogenous variables (Bahn and Cameron 2012). This has been clear from the example used under the analysis of demand and supply mechanism. It was seen how the demand and supply curves shift with other respective determinants fluctuations. It was also presented how demand and supply curves behave in case of own price changes while holding other determinants constant. References Bahn, S. and Cameron, R., 2012.

Demand and Supply of Certain Resources in Australia Question: Discuss about the Demand and Supply of Certain Resources in Australia. Answer: Analysis of the news article The topic is selected from the ABC news which is uploaded by the Nick Harmsen on 9th March 2017. This article talks about the demand and supply of gas resource in Australian market. This article was presented by the Australian energy market operator which indicates about the shortage of gas supply in Australia (Harmsen, 2017). Gas is a major resource in the market and it can impact the several activities of small business and households. Gas market of Australia is increasing rapidly from last one decade. In this article it is stated that the lower supply of gas in the Australian market would affect the nations power supply. In Australian market, the equilibrium in the supply and demand of gas is not meeting. At the same time, the Australian population is increasing rapidly so it can also threaten the supply of gas in the market. Owing to this, the residential and business would be impacted by the lesser supply of gas (Austrade, 2013). Further, the New South Wales and southern Austral ia would be affected by this lower supply. It is stated that if the supply is not meeting up to the level of demand it resulted into the increment in the price of the gas. From this demand and supply, New South Wales and Southern Australia would be influenced and price of the gas would be increased up to the $14000 per megawatt hour (AEMO, 2016). Along with this, it is also discussed that the lower supply of gas would create a challenge for the energy sector to increase the production of gas (Industry, 2016). Further, the higher demand would influence the commercial and non- commercial people. The economic analysis Australia is one of the most leading economy in the world which is growing rapidly. Oil and gas industry in Australia has a significant contribution in the economy through investment, job opportunities and revenue (Industry, 2016). Further, the contribution is expected to $67 billion by 2030. Demand and supply are the important concepts in microeconomics and these can affect the market scenario of a particular product. Demand can be defined as an ability of consumers to buy the product at specific price (Bumas, 2015). Further, price is major concern in demand of a product. The demand of gas has increased due to the lower production of the gas and the households and commercial business are demanding more gas. On the other hand, supply refers to the quantity of a product that is available in the market at a specific price and customers are ready to buy it on that price. The supply of the gas resource is less as compared to the current demand in Australian market (Energyexempler, 2014). Along with this, the consumption of the gas has increased from last five years. To meet the specific demand, it is requires to increase the supply by 363 gigawatt hours. In summer season, the demand of the electricity is more as compare to the other season. It is stated that the demand of resources increases if the price decreased or the price of substitutes increases but some of the resources are necessary to use then the demand of these resources increases without any price movement (Erickson, 2014). The same situation arises here with the energy industry due to the high demand in market. Demand and supply equilibrium is a state when there is a balance between the demand and supply. It may be affected by the situation factors that lead to the unbalance between the demand and supply movement (Boys, and Melvin, 2013). Australia does not have enough gas production to satisfy the arising demand. The unbalance between demand and supply would be challenging for Australian marketers to control the short term and long term impact. Industrial processing is the important component which initiated the demand increase rapidly. Moreover, the price for the gas has also increased by 60% due to heavy consumption (ABC, 2015). It is also found out the export of the liquefied natural gas has increased it would also influence the pricing of the gas in market. Apart from this, the finance is a major problem for the gas companies to expand the business in this sector and adopt the innovative ways to meet the demand. Demand and supply curve Figure: Demand and Supply (Source: Boys and Melvin, 2013) From the graph of demand and supply it can be reviewed that the market is pool of demand and the supply meet the same by time passing and a time when the demand and supply are equal it called equilibrium situation. On the other hand, In Australian market the situation is too critically for the supply of gas for households and commercial purpose. It is expected the supply of the gas in market would be 20% less from the year 2017 to next five years it would influence the energy sector negatively by reducing the revenue and the hike in the price. Recommendations to the key players in Australian gas market Australian market would face the unbalance between the supply and demand of gas resource in perspective market so the leading companies and governments can resolve this problem through underpinning the potential demand of gas. Further, the government can support the oil and gas companies though supporting them by providing finance to develop more projects (Industry, 2014). Along with this, government can also subsidize the energy sector those are performing well and contributing to the economy well. This economic unbalance would also impact the revenue and operations of small industry because of high cost to buy the gas. To overcome the situation there are many other sources are available which can be used as substitutes like solar power and wind power. It can be recommended to the market players that they can produce more by maintaining the cost for it. On the other hand, gas can be imported if the demand is highly exceeded. Along with this, the energy market can invest in new pipelines projects to mitigating the demand and the new field for the execution of gas can be explored (ABC, 2017). Moreover, energy market can effectively execute the policies which can help the market players to increase the production. With this, companies can transport the gas from where is it cheaply produced at the different locations. New liquefied natural gas projects may also be an alternative solution for this problem and fetch the demand for long term. Conclusion Australian eastern market is facing the problem of sufficient supply for gas because the high demand in the market. Demand crisis would impact the oil and gas business because of less supply, revenue would be affected. On the other hand, energy market companies and government is the major players that can draw the policies to meet the high demand of gas. Government can provide the fund for new fields and project development at low interest rate. It can be concluded that there are various source available as substitutes for the gas as production of electricity by solar and wind. Attractive investment may support the energy sector to develop the new project and increase the production of gas to satisfy the demand. References: ABC, (2015).
