  Pesticide misuse - Wikipedia, the free encyclopedia
Under United States laws, pesticide misuse is the use of a pesticide in a way that violates laws regulating their use or endangers humans or the environment; many of these regulations are laid out in the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA).
Pesticide misuse that endanger human health or even cause death get the most attention from law enforcement, yet pesticide poisonings are still a common problem, particularly with agricultural workers.
Pesticides are toxic compounds and the labels are specifically designed to make their use effective and safe.

 Biological control and holistic plant-health care in agriculture
Biological control describes the normal state of affairs in naturel undisturbed ecosystems, where populations of organisms exist in a dynamic equilibrium and species or individuals unable to compete or to find an ecological niche are replaced by those that can.
The era of modern biological control, involving the deliberate transfer and introduction of naturel enemies of insect pests, was launched 100 years ego with the highly successful introduction of the vadalia beetle from Australia to California in 1888 to control the cottony cushion scale of citrus.
Pest control by sanitation is accomplished mainly by physical and chemical methods, including sterilization of the surface of seeds or tools by heat or chemical-disinfectants, physical separation of disease-free tissue from infected plants or weed seeds from crop seeds, or physical removal of weeds or infested debris from an orchard or field.

 EPA: Federal Register: Proposed Policy; Plant-Pesticides Subject to the Federal Insecticide, Fungicide, and Rodenticide ...
EPA defines the term ``biological control agent'' as ``any living organism applied to or introduced into the environment that is intended to function as a pesticide against another organism declared to be a pest by the Administrator'' (40 CFR 152.3).
Although plants used as biological control agents were excluded from FIFRA regulation under 40 CFR 152.20, substances that are extracted from plants and used as pesticides are not similarly excluded.
Since the pesticidal substance may have the potential to be expressed in the entire crop and related plants, it may be difficult to limit the exposure of threatened or endangered species.

 Environmental issues of forages - Define the term biodiversity and explain how this concept could be applied to forage ...
Using herbicides to control weeds, using pesticides to control insects, fumigating soil to control microorganisms, using rodenticides to control rodents, importing domesticated livestock into areas that used to support a mixed wildlife population are all ways in which agricultural production practices can reduce biodiversity.
One criticism often leveled at modern agriculture is the dependence on a few crops that are genetically similar.
The advantage of this approach to food production has been the development of crops that produce high yields per unit area of land in response to inputs of fertilizer, irrigation, and agrichemicals in general.

 Designing Insects by Thomas A. Miller
The key feature of symbiotic control, which uses symbionts to control pests or disease, is identifying a symbiont that has both an intimate relationship (called mutualism) with a diseased host and access to the pest or pathogen attacking it.
The difference between symbiotic control and biological control, which uses organisms such as parasites or predators to control pests or disease, is the transgenic pest organism acts as a symbiotic control agent itself rather than parasites or predators acting to control the pest.
Symbiotic control is different from ordinary microbial pesticides, which are used the same as commercial insecticides, in having greater selectivity and fewer side effects.

 Pest Management Using Natural Enemies
These approaches to pest management may be used to reduce pesticide use.  When used effectively these methods can be a safe and effective approach to pest management.  As with all such management strategies, it is critical to correctly and comprehensively identify all advantages and disadvantages of a particular strategy.
Some of the keys to successfully using this strategy are: properly identifying the pest, accurately estimating the population, obtaining the correct natural enemies, following release directions correctly, and monitoring the effectiveness of the biological control.

 Environmental issues of forages - Discuss advantages and disadvantages in using synthetic agrichemicals in forage ...
More specifically the term agrichemicals includes herbicides (chemicals that are toxic to weeds), pesticides (chemicals that are toxic to insects), fungicides (chemicals that are toxic to fungi - a group of organisms that cause diseases in plants and animals), rodenticides (chemicals toxic to rodents), and antibiotics administered to livestock.
Furthermore, it is far beyond the scope of this curriculum to address the many details of the hundreds of compounds that are in the category of agrichemicals.
Perhaps the most useful and concise way to discuss the issue of agrichemicals in the context of this curriculum is to point out major advantages and disadvantages in the use of these products in forage production.

 Evaluation of the Sustainability of the Farms
A long list of definitions for "alternative" agriculture can be found in Harpers’ work as well, and these run the gamut from highly idealistic notions of agriculture to "anything not conventional".
The main difference between the two is the alternative farmers’ (AF) reluctance to use synthetic fertilizer, pesticides, and herbicides.
However, most of us felt that the AF is more sustainable than the CF because the AF's crop rotation, methods of weed control and manure application allows a greater control over the soil nutrients and levels of organic matter.
