Pest management-ENT 684 Maimela N. 2004009268 Pesticides resistance and the implications thereof- Pesticide resistance is a growing concern. Can management strategies and new pesticides keep up? Abstract The use of pesticides has increased agricultural production. However, the intensity and frequent use has resulted in the development of resistance by pests. Pesticide resistance is increasingly becoming a worldwide problem with an estimated number of 583 species reported to be resistant. This evolutionary process negatively affects farmers, chemical companies, consumers and the environment. Management strategies such as Integrated Pest Management (IPM) successfully delay the development of resistance. The production of new pesticides, …show more content…

The development of new and chemical products with novel modes of action, and Integrated Pest Management (IPM) are factors that contribute to the reduction of pesticide resistance(Whalon et al. 2008). Effectively managing pesticide resistance will also help in reducing the harmful effects of pesticides by decreasing the rates of pesticide use and prolonging the efficacy of environmentally safe pesticides Discussion What is pesticide resistance? Pesticide resistance refers to the natural ability of a biotype of an organism to survive exposure to a pesticide that would normally kill an individual of that species. Pest organisms of the same species can have genetic differences and this is referred to as biotype(ISU 2010). Pesticide resistance is increasingly becoming a worldwide problem faced by the animal and plant production industry. Insecticide Resistance Action Committee (IRAC n.d), reported approximately 583 species that are known to be resistant to insecticides worldwide (Figure 1).

    There are many issues regarding the raising and producing of various livestock animals, and the use of pesticides on various types of crops. The movie Food.Inc does a good job explaining these issues, but in a very biased way. It makes agriculturists look like terrible people, when this is not the case.

  • Industrial Garlic and Organic Garlic Experiment with Pesticides

    1297 Words  | 3 Pages

    The data which has been collected from the Garlic sprouting experiment proves to be inconclusive; however this is not to say that the data was not informative, or did not have influence on the questions being asked in the lab. The lab question states “Do insecticides and pesticides used on Industrial Garlic negatively impact the rapidity of growth of sprouts; in comparison to Organic Garlic?”. In answering this question, growth must be studied through time period, and quality of length. When looking at the data from Table 1, it can observe that on May 12 Industrial Garlic grew 1 sprout more than Organic did and on May 17 the Industrial Garlic grew 5 more sprouts than Organic did. However by May 20, just 8 days after initial growth (on May 12), the Organic Garlic has grown more by 7 sprouts. From the point forward, it seems as though Organic Garlic continued to out-sprout Industrial Garlic, until you look at May 25, the last data collection day. At this time you realize that Industrial Garlic had 31 sprouts but Organic Garlic only had 29 sprouts. Looking at Graph 1, we can see that both Garlics have an overall growth trend, in which Organic Garlic seems to start off slower, and grow more exponentially toward the end of the data collection period, but between May 20 and May 24 the data looks as thought it would have started to crash, if growth were to be continuously monitored after the 20 day time period. Industrial Organic seems to have a similar trend, yet the growth in Industrial Garlic seems to climb in sprout count less rapidly than the Organic brand did. It can also be observed that although the Industrial band Garlic dips significantly on May 19, it continues to rise once again for the rest of the time period. This indicat...

  • Colony Collapse Disorder and Pesticides

    1578 Words  | 4 Pages

    Colony Collapse Disorder and Pesticides From around the year 2006, many bee farmers in the U.S.A and some parts of Europe started reporting sharp declines in their bee stocks. The reason for these declining numbers was not known and therefore scientists named it colony collapse disorder (CCD). Colony collapse disorder (CCD) is a not very old phenomenon and it became popular when large numbers of bee colonies started disappearing. The disappearance was mysterious since no dead bees were found in or around the beehives after a colony’s number was reported to have gone down or vanished.

    Spinosad insecticide is an organic compound, produced by some bacteria microbes present in the soil that were first discovered surviving in rotting sugarcane rums (Thomas, 2001). It is made of two complex compounds spinosyn A and D. The compounds are very toxic to a variety of insects and less toxic to humans and some important insects beneficial in the farm such as bees. This insecticide was first discovered by Lacey and Goodfellow, in 1975.

  • Organic Farming vs Factory Farming

    Nature practices diversity and for good reason. In nature and organic farming, if there is a threat to one species, there are others to balance the decrease in the threatened species. Conventional farmers and the modern food industry argue that planting the same crop year after year is convenient and profitable because it cuts down on the different types of farm equipment necessary in production, and initially, on the types of pesticides, herbicides, and fertilizers needed. However, in this unnatural environment, tremendous amounts of pesticides and fertilizers are needed to support crops as increased resistance occurs year after year (Pollan 72).... ...

  • Argumentative Essay On Pesticides

    864 Words  | 2 Pages

    As time has progressed, there has always been an overarching need for high amounts of crop production throughout the world. With the rapid rate of population growth, the need for crops and other sources of nutrients is only increasing. In order to meet these high demands and increase yields, farmers and other agriculturalists have started implementing the use of pesticides. These chemical mixtures are being used in order to prevent, destroy, repel or mitigate any pests from destroying growing crops. However, using pesticides on crops can create massive amounts of pollution, negatively affect an individual’s health, and can spark biodiversity loss within an ecosystem. According to Michael C.R. Alavanja, “Over 1 billion pounds of pesticides are used within the United States (US) each year and approximately 5.6 billion pounds are used worldwide”. With all this in mind, it is clear that pesticides should not be made available to farmers and agriculturalists, and should

The Department of Agriculture wants herbicide resistance to be further investigated through this paper. In this briefing paper a range of areas will be covered including mechanisms of herbicide resistant weeds and the major instances. Rye grass or L. rigidum is an ever evolving weed and is the world’s leader in herbicide resistance which has a range of mechanisms which have led to its survival and resistance. But are herbicide resistant weeds like L. rigidum becoming more common if so what are the projections of further evolution to herbicides?

  • Pesticides Essay

    1456 Words  | 3 Pages

    Pesticide is a chemical used to prevent, wipe out and control the pest problem in agriculture. The use of pesticides have 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 insecticides, Chlorpyrifos, sprays widely on a variety of food and golf courses in order to control pests in a cornfield. However, “Chlorpyrifos can cause cholinesterase inhibition in humans; that is, it can over stimulate the nervous system causing nausea, dizziness, confusion, and at very high exposures (e.g., accidents or major spills), respiratory paralysis and death.” (EPA GOV) In the market has thousands of products are similar as Chlorpyrifos.
