- Enter subhead content here. Broad-Spectrum Pesticides- pesticides that kill a variety of organisms, including some that are beneficial, in addition to the target pest. Narrow-Spectrum Pesticides-pesticides that only kill the organism for which it was intended to and not any other organisms. Narrow-spectrum pesticides are more ideal than broad-spectrum pesticides because non-target species would not be harmed. However, most pesticides are broad-spectrum pesticides.

What Are Pesticides? - Definition and Difference Between Narrow-Spectrum & Broad-Spectrum An example of a broad-spectrum pesticide is methyl bromide, which is designed to control pests ranging from small insects and pathogens to larger weeds and rodents. The pesticide can be injected into the ground to kill organisms in the soil that might harm the plant while it is growing.

Spinosad Insecticide - A natural pesticide from soil microbes -. Spinosad is a relatively new insecticide that is made up of two complex organic compounds, spinosyn A (right) and spinosyn D. These compounds are produced by certain microbes that were first discovered in soil found at an abandoned rum factory.Spinosad is a broad-spectrum, organic insecticide.The term broad-spectrum means that it is toxic to a wide variety of insects. It is, however, relatively non-toxic to mammals and beneficial insects. If used carefully only insects that actually eat something that has been treated, such as a leaf, are affected.pinosad is a broad-spectrum, organic insecticide. The term broad-spectrum means that it is toxic to a wide variety of insects. It is, however, relatively non-toxic to mammals and beneficial insects.

Pesticide Pesticides can also be considered as either biodegradable pesticides, which will be broken down by microbes and other living beings into harmless compounds, or persistent pesticides, which may take months or years before they are broken down: it was the persistence of DDT, for example, which led to its accumulation in the food chain and its killing of birds of prey at the top of the food chain.

What Are Pesticides? - Definition and Difference Between Narrow-Spectrum & Broad-Spectrum Broad-Spectrum Pesticides. Although sometimes it is desirable to target a specific species or group of organisms, in some situations, it is necessary to eliminate a wider range of pests that are causing harm. Broad-spectrum pesticides are pesticides that are designed to kill or manage a wide variety of organisms. Broad-spectrum pesticides are used when many different species of organisms are causing harm or when the specific organism causing harm is unknown. In order to kill or manage such a large variety of organisms, most broad-spectrum pesticides are designed to target a system that is common in many organisms, such as the nervous system or muscular system.

- International treaties such as the Stockholm Convention on Persistent Organic pollutants have attempted to regulate and restrict the use of pesticides and other chemicals which are highly persistent in the environment (e.g., DDT) since such persistence may lead to biological consequences for wildlife and human health.. Racke, N. Simmons, C. Tiu Dow AgroSciences 9330 Zionsville Road Indianapolis, Indiana USA 46268 Introduction At times, pesticide opponents may raise questions about chlorpyrifos and other modern insecticide products concerning their potential classification as “persistent organic pollutants” or “POPs”.

Measuring Pesticides and How They Transform in the Environment The method uses solid-phase extraction to remove pesticides from a water sample and then employs gas chromatography/mass spectrometry. The detection levels in many traditional methods are too high for studies on the fate of these pesticides in the environment. For some of these pesticides, but more importantly for the pesticides' degradates, methods to measure their concentration in water were not available. These methods are now being used by the U.S. Geological Survey's Toxics Program and NAWQA to assess the fate of these pesticides in the environment.

- In addition, some broad-spectrum pesticides can be relatively selective when used infrequently and at very low rates: for example, 0.5 pint per acre of chlorpyrifos (Lorsban) for katydids, compared to high rates (6 to 12 pints per acre) used for California red scale.

Narrow-spectrum Vs. Broad-spectrum Antibiotics: A Comparative Analysis Narrow-spectrum Vs. Broad-spectrum Antibiotics: A Comparative Analysis The difference between narrow-spectrum and broad-spectrum lies in the range of bacteria that the antibiotic can act on. The latter class of antibiotics are better at treating different types of bacterial infections.

- The FDA has defined “broad spectrum” as products with a Critical Wavelength® value of over 370nm. In 2011, the FDA decided to use Critical Wavelength® to define whether a product is “broad spectrum.” Only products with a Critical Wavelength® value over 370nm will now be allowed to make a broad spectrum claim.ince 2007, the American Academy of Dermatology (AAD) has asked the FDA to required placement of an absolute Critical Wavelength value on sun protection products to help them select the best products for their patients with photosensitivities.
