Cuts costs and increases yields in agriculture.
Agriculturally, the advantages of gardening chemicals guarantee higher crop yields and allow farmers to produce better quality crops. It is estimated that 37% of crops in the United States are destroyed by pests each year.
Herbicides control weeds so that crops can flourish without unwanted plants competing for vital nutrients, space, water and sunlight. Fungicides protect plants from disease-causing organisms that can spread quickly and destroy fields of crops.
Examples of specific synthetic chemical pesticides are glyphosate, Acephate, Deet, Propoxur, Metaldehyde, Boric Acid, Diazinon, Dursban, DDT, Malathion, etc.
Herbicides to kill or inhibit the growth of unwanted plants, also known as weeds. Insecticides to control insects. Insect Growth Regulators to disrupt the growth and reproduction of insects. Rodenticides to kills rodents like mice, rats, and gophers.
While organic pesticides are for the most part safer and more ecologically sound, they are not perfect. They usually have a shorter residual activity (they don’t last as long) than chemicals; they’re often more expensive than conventional pesticides, and for serious problems, they may not be 100% effective.
Aquaculture can alleviate human caused pressure on native fisheries.
Fish farms can impact wild fish populations by transferring disease and parasites to migrating fish. Aquaculture can also pollute water systems with excess nutrients and fecal matter due to the large numbers and concentrations of farmed fish.
because of the difficulty and expense of cleaning up a contaminated aquifer, preventing contamination is the least expensive and most effective way to protect groundwater resources.
Compared with conventional agriculture, organic farming uses fewer pesticides, reduces soil erosion, decreases nitrate leaching into groundwater and surface water, and recycles animal wastes back into the farm. These benefits are counterbalanced by higher food costs for consumers and generally lower yields.
Not only that, but there is much evidence that natural pesticides allowed in organic farming are just as toxic as synthetic pesticides. … Synthetic chemicals are more toxic than natural chemicals. 2. Organically grown food is better for you because it’s all natural.
Organic pesticides generally come from things in nature that can be used to control pests. … Many organic pesticides are less toxic than their synthetic counterparts, but that doesn’t mean they are safe or won’t cause environmental harm. Just like synthetic pesticides, organic pesticides are formulated to kill.
What Are the Advantages of Chemical Energy?
List of the Advantages of Chemical Energy
Helps for soil to retain nutrients and moisture. Long-term environmental benefits as they are less likely to contaminate lands and waters. Far safer to the overall crop for both grazers and farmers.
In 1934, the fungicide, thiram, was developed which led to the development of a series of effective and widely used fungicides over the next ten years. Swiss chemist, Paul Müller, developed a new compound in 1939 that would profoundly change the lives of farmers and people around the world.
Types of Pesticide Ingredients
DDT (dichlorodiphenyltrichloroethane) was first prepared by Othmar Ziedler, an Austrian chemist, in 1825, but the Swiss chemist Paul Hermann Müller did not discover DDT’s insecticidal properties until 1939 — a discovery that led to Müller’s award of the Nobel Prize in 1948.
Their major advantage is adding bulk to the soil. Except for manure, the organics generally release their nutrients over a fairly long period. However, the potential drawback is that they may not release enough of their principal nutrient at a time to give a plant what it needs for best growth.
Organic pesticides are generally considered to be pesticides derived from naturally occurring sources such as minerals, plants, or animals. … Some synthetically produced pesticides meet the criteria for use in organic agriculture. For example, copper sulfate and paracetic acid can be used for plant disease control.
Disadvantages of Aquaculture: Technology not available for many possible crops. Lack of knowledge about aquaculture. Competition from wild fish and seafood.
Aquaculture offers many environmental benefits, relative to other forms of livestock farming. Marine aquaculture operations typically have a smaller carbon footprint, and require less land and fresh water. They are more efficient at converting feed into protein for human consumption than beef, pork, and poultry.
Antibiotics are widely used in aquaculture. Intensive farming drives indiscriminate use of antibiotics, which results in residues of antibiotics in cultured aquatic products and bacterial resistance.
