Evaluation of Fungicide Control of Sclerotinia Stem Rot on Canola (SSR) Yin Chen Description of disease affecting crop Sclerotinia stem rot (SSR) is caused by fungus named sclerotinia sclerotiorum (Lib.) de Bary. It is a common disease in oilseed rape (Brassica napus) field. In Sweden, S. sclerotiorum can cause 60% yield reduction in infected fields (Nordin, 1992). SSR is a major disease of canola in North Dakota. The incidence ranged from 7-19% in North Dakota from 1991 to 1993. ( Lamey, 1995).
direction. Researchers have discovered that fungicides alter bee behaviour. “fungicides are used to control things like fungus on apples, and weren’t expected to have an impact on healthy bees” (USnews). This was a huge shock in the scientific world because fungicides were not meant to harm insects at all. “fungicides, which we didn’t expect to harm insects, seem to have a sublethal effect on bee health” (nbcnews) While fungicides do not directly kill bees, fungicides do cause the bees to die nonetheless
clippings to prevent contamination of areas previously infected. Healthy grass subsequently returns upon elimination of the infection. Use of fungicide before infection occurs serves as a preventive measure. Dollar Spot: Dollar spot thrives in... ... middle of paper ... ...his disease. American-Lawns.com suggests controlling this disease by applying fungicide in October or early March after which a thorough watering is necessary. The arrival of warm weather kills the infected grass. Stripe
Cauliflower is one of the most important vegetables of India. Cauliflower plant belongs to the family cruciferae and consumed as a vegetable in curries, soups, salads and pickles. India is the second largest producer of cauliflower after China and produces 4.694 M mt of cauliflower per year from 0.256 M ha area with an average productivity of about 18.3 mt ha-1 (http://www.ncpahindia.com/cauliflower.php; Senguttuvan et al. 2014). Cauliflower is an excellent source of nutrients having low fat and
Soybeans are a popular legume used to produce soy milk, tofu, soy sauce and other products. Also known as edamame beans, the FDA reports that soybeans may help reduce cholesterol and improve your heart health. Grow your own soybeans to have them fresh from the garden at a fraction of the cost of retail stores. Best Planting Time Due to the soil conditions, early May is typically the optimal time to prepare and plant soybeans. If you want to have the best possibility of a successful crop, you cannot
Jillyan Swasey Crystal Anderson Elements of Equine Science 7 November 2014 Thrush The horse’s hoof is susceptible to many infections and unsoundnesses. These problems can be biological in nature, arising as a result of bacterial, viral, or fungal infections. Others are derived from issues of neglect, exposure to factors that can cause unsoundnesses, or encounters with septic conditions. Unsoundnesses can occur in horses of all ages but older horses are more susceptible to them. The time of year plays
The Use of Fertilisers and Pesticides in Agriculture Agriculture today dominates the majority of all land uses. As a result it has a fundamental role in maintaining the countryside and protecting the environment. The development of the use of fertilisers and pesticides has dramatically increased the efficiency of food production and has in fact more than quadrupled food production in the last century[1]. They also have reduced the cost and increased the variety of foods available. However
The Scientific American “National Center for Food and Agriculture Policy, the top two organic fungicides, copper and sulfur, were used at a rate of 4 and 34 pounds per acre in 1971”. While conventional farmers used on average 1.6 pounds per acre when using synthetic fungicides. Since natural fungicides are less effective farmers apply more chemicals to stay effective. The common consumer does not have the drive to look up the specifics about organic
Why are people so fiercely opposed to Genetically modified organisms? According to Shermer, Michael they believe that all genetically organized organisms are unnatural and are controlled by large corporations ”shermer” but some people don’t even know what they actually are. Genetically modified organisms are plants, animals or bacteria that have had their DNA altered artificially. (we don’t)Scientist use two methods to do this. The first method is to use a gene gun to shot genes into DNA and repeat

The most widely used ones are insecticides, herbicides, rodenticides, bactericides, fungicides, and larvicides. In the US the EPA is the main body tasked with regulating pesticides. The USDA monitors pesticide residue in meat, eggs, and dairy, while the FDA monitors fruits and vegetables. The EPA’s power is defined by multiple laws. The Federal Insecticide, Fungicide, and Rodenticide Act allows EPA to register pesticides upon meeting a set of guidelines. The Federal Food, Drug
Weil 1 Copper is one of the earliest elements known to man. Because of its distinct red color, Copper is very easily identified. In the ancient times, copper could be found lying in the ground in its unattached state without interaction to other substances. Copper and its compounds have many uses in today’s society. Copper has many chemical properties that make it unique. The Atomic number of copper is 29. An Atomic number is a measure of the amount of protons in the nucleus of an atom. Protons are
years, researches has struggled to find what causes the death of masses of bees, but they have a few surmises: Most of the crops we plant are sprayed with fungicides and pesticides that are used to kill the insects on the crops. But along with other insects, bees are hurt too by those compounds; even though bees can digest most toxins, the fungicides are deadly for them. Bee keepers feed their bees artificial supplements instead of real, nutritious food, which causes the lack of diverse pollen for
farmers can owe it all to the pesticides they use. If no pesticides were used, then insects would destroy crops, feeding off of their leaves and produce until hardly anything is left. According to corncommentary.com, Without the use of pesticides and fungicides, most fruit and vegetable crops would suffer a 50-90 percent loss due to uncontrolled insects and disease organisms. Despite what most people believe, even organic growers use pesticides on their crops that have been approved for such organic growers
The discovery of the Americas brought a large exchange of people, diseases and crops. Corn, peppers, tomatoes, cassava, cocoa, rubber and tobacco were some of the crops introduced to the Old World. Coffee, oranges, bananas and sugar cane were introduced to the Americas. One of the most important crops brought to the Old World was the potato. Potatoes, as a substitute for wheat or rice, provided peasants a new source of calories. Potato was originated South America and then introduced to the Old World;
Control A pest is usually seen as an organism potentially hazardous to health and is in competition with humans for space food or soil. Pesticides are any chemical or biological agent that kills plant or animal pests; herbicides, insecticides, fungicides, rodenticides, etc. are all pesticides. There are various types of chemical pesticides available such as contact pesticides which are sprayed directly onto the crop, systematic pesticides, which are sprayed on the crop but absorbed by the
discourages pests (such as insects, weeds, birds, mammals, and fish) which destroy property or crops, or spread disease. There are many different types of pesticides, including insecticides (which kill insects), herbicides (which kill plants) and fungicides (which kill fungi). Many pesticides can be grouped into chemical families. Some insecticide families include organochlorines, organophosphates, and carbamates. Organochlorine hydrocarbons could be separated into dichlorodiphenylethanes (DDT), cyclodiene
become a common practice around the world, and used almost everywhere, such as agricultural fields, homes, park and school, and so on. Most pesticides are insecticides, herbicides and fungicides that have distinct purposes. Insecticides are used to control insects; herbicides are used to destroy plants; fungicides are used to prevent molds and mildews. Most commonly pesticides contain highly toxic chemical such as Acid copper chromate (ACC), Acephate and Chlorpyrifos, and so on. One of example of
The population of honeybees has been declining due to Colony Collapse Disorder (CCD). It is a serious problem that threatens the stability of commercial beekeeping and pollination operations in the US. Scientist have not identified the real cause of CCD. Another reason for bee population declining is because of diseases, parasites, and stressors. One stressor is because of pollen/nectar that has no nutrients in it. Another problem is that they have no available water and what water is available
