What does EPA say about plant-incorporated protectants?

EPA scientists assess a wide variety of potential effects associated with the use of plant-incorporated protectants. Based on our reviews of the scientific studies and, in many cases, peer reviews by the Federal Insecticide, Fungicide and Rodenticide Scientific Advisory Panel, EPA determined that these genetically engineered PIP products, when u...

What are placplant-incorporated protectants?

Plant-incorporated protectants are pesticidal substances produced by plants and the genetic material necessary for the plant to produce the substance.

Are plant incorporated protectants considered pesticides under FIFRA?

Plant incorporated protectants (PIPs), such as the Bt toxin in corn, are considered pesticides under FIFRA because they are introduced into plants with the intention of preventing, destroying, repelling, or mitigating a pest (FIFRA §2).

How do scientists use genes to control pests in plants?

For example, scientists can take the gene for a specific Bt pesticidal protein and introduce the gene into the plant's genetic material. Then the plant manufactures the pesticidal protein that controls the pest when it feeds on the plant.

What are plant incorporated protectant?

Plant-incorporated protectants are pesticidal substances produced by plants and the genetic material necessary for the plant to produce the substance. For example, scientists can take the gene for a specific Bt pesticidal protein and introduce the gene into the plant's genetic material.

Can plants be genetically modified?

GM is a technology that involves inserting DNA into the genome of an organism. To produce a GM plant, new DNA is transferred into plant cells. Usually, the cells are then grown in tissue culture where they develop into plants. The seeds produced by these plants will inherit the new DNA.

How have genetically modified organisms GMOs used in agriculture helped the environment?

GMOs also reduce the amount of pesticides that need to be sprayed, while simultaneously increasing the amount of crops available to be eaten and sold. Over the last 20 years, GMOs have reduced pesticide applications by 8.2% and helped increase crop yields by 22%.

What does inserting pesticides at the genetic level do?

Herbicide-tolerant genetically modified (GM) crops have led to an increase in herbicide usage while insecticide-producing GM crops have led to a decrease in insecticides.

How are plants engineered?

How are plants genetically engineered? Genetic engineering copies a gene or genes from an organism with a desired trait and adds the gene or genes to a single plant cell in a laboratory. A new plant is generated from the plant cell containing the added DNA.

What are the advantages and disadvantages of genetically modified plants?

The pros of GMO crops are that they may contain more nutrients, are grown with fewer pesticides, and are usually cheaper than their non-GMO counterparts. The cons of GMO foods are that they may cause allergic reactions because of their altered DNA and they may increase antibiotic resistance.

How do GMOs protect crops?

GMO crops that are tolerant to herbicides help farmers control weeds without damaging the crops. When farmers use these herbicide-tolerant crops they do not need to till the soil, which they normally do to get rid of weeds. This no-till planting helps to maintain soil health and lower fuel and labor use.

What are three environmental benefits of GMOs?

GM crops build soil structure, clean air, and conserve water With more beneficial insects in the soil along with the remains of the field's previous crops, the amount of organic material in soil increases, allowing the soil to retain more moisture.

Why are GMOs important to agriculture?

Most of the GMO crops grown today were developed to help farmers prevent crop and food loss and control weeds. The three most common traits found in GMO crops are: Resistance to certain damaging insects. Tolerance of certain herbicides used to control weeds.

What are GMO pesticides?

The vast majority of Genetically Modified Organisms (GMOs) grown in the U.S. are engineered to produce their own pesticides, or survive direct application of pesticides. For example, Monsanto's Roundup Ready crops are engineered to survive direct application of glyphosate (the primary ingredient in Roundup).

How do pesticides affect the environment?

Impact on environment Pesticides can contaminate soil, water, turf, and other vegetation. In addition to killing insects or weeds, pesticides can be toxic to a host of other organisms including birds, fish, beneficial insects, and non-target plants.

Why is organic better than GMO?

Organic is non-GMO because the use of GMOs is prohibited in organic production. For example, organic farmers cannot plant GMO seeds, organic livestock cannot eat GMO feed, and organic food manufacturers cannot use GMO ingredients.

What is plant incorporated protectant?

All plant-incorporated protectants for disease control market ed to date target viruses. Focus has been on virus coat protein genes and virus replicase genes, and using genetic engineering to incorporate them into plants. There is potential to genetically engineer plants that produce natural fungicidal products.

Why are biopesticides good for plants?

Many biopesticides have additional benefits when applied to plant systems that make them good candidates for integrated pest management . Certain microbial biopesticides improve the uptake of soil nutrients by plants. They are effective against plant pathogens that attack the same crops ( Glare et al., 2012 ).

What is a biopesticide?

Biopesticides are mainly the subclass of pesticides that are naturally occurring or derived materials from living organisms or their metabolites. They generate only minor negative outcomes compared to chemical pesticides. Put simply, a biopesticide is a formulation based on the activity of an agent originating in nature but has pesticidal action properties. According to the US Environmental Protection Agency (US EPA), biopesticides are certain types of pesticides derived from natural materials such as animals, plants, bacteria, and certain minerals ( USEPA, 2008). The US EPA has categorized biopesticides into three major classes based on the types of bioactive ingredients or agents used for pest control: (i) biochemical pesticides; (ii) microbial pesticides; and (iii) plant-incorporated protectants.

What are the three major classes of biopesticides?

The US EPA has categorized biopesticides into three major classes based on the types of bioactive ingredients or agents used for pest control: (i) biochemical pesticides; ( ii) microbial pesticides; and (iii) plant-incorporated protectants.

What are the functions of microbial biopesticides?

The microorganisms in microbial biopesticides function in several ways. Some are biological control agents that directly attack the pathogen, such as Coniothyrium minitans in the formulated product Contans WG. Others grow on and around plant roots creating a biological defense against root-infecting fungi, for example, Trichoderma harzianum in RootShield. Compounds that directly affect pathogens and/or induce SAR are in other microbial biopesticides, such as the lipoproteins produced by Bacillus subtilis in Serenade.

What is the role of the EPA?

The main role of the EPA is to ensure that all Americans are protected from significant risks to human health and to the environment where they live, learn, and work. EPA regulations contribute to making American communities and ecosystems diverse, sustainable, and economically productive ( Nestmann et al., 2002 ). The regulatory activities of the EPA are governed by the authorities and requirements of specific environmental laws. These laws direct the EPA to regulate many kinds of “pollution,” including pesticides, with a focus on how they affect different aspects of the environment. “Environment” is generally defined in these statutes as including human health, plant and animal wildlife, water quality, and air quality ( National Research Council, 2009 ). There is a general recognition by the courts, the scientific community, and the regulatory community that the EPA should consider other factors along with the science when it makes decisions about risk management ( EPA, 2005 ).

What are the ingredients in fungicides?

There are many fungicides that are biochemical biopesticides. Their ingredients include potassium bicarbonate, hydrogen dioxide, botanical oils, and plant extracts. Many have demonstrated efficacy for powdery mildews. The botanical oils including clove oil, corn oil, cottonseed oil, jojoba oil, neem oil, rosemary oil, sesame oil, and thyme oil, which have already been discussed in the section ‘Reduced-risk and minimum-risk fungicides’, are also considered biochemical biopesticides. Products are being marketed with capsaicinoids and with extracts from garlic and giant knotweed ( R. sachalinensis ). Most of these are presently in FRAC group NC (not classified).

What is plant incorporated protectant?

Plant-incorporated protectants are pesticidal substances produced by plants and the genetic material necessary for the plant to produce the substance. For example, scientists can take the gene for a specific Bt pesticidal protein and introduce the gene into the plant's genetic material. Then the plant manufactures the pesticidal protein ...

What is required before EPA can register a pesticide?

Before EPA can register a pesticide there must be sufficient data demonstrating that it will not pose unreasonable risks to human health or the environment when used according to label directions. When assessing the potential risks of genetically engineered plant-incorporated protectants, EPA requires extensive studies examining numerous factors, such as:

When was PIP first used?

Before the first PIP product was registered in 1995 , EPA required that PIP products be thoroughly tested to ensure they meet federal safety standards before they were used on human food and livestock feed crops. See How the Federal Government Regulates Biotech Plants.
