What is the most commonly used fungicide?

Systemic fungicides. Systemic fungicideshave been developed since the 1960s and are now the most commonly used fungicides. On entry into the crop plant, they can move to a certain extent within the crop, usually in the xylem vessels, to the site of infection.

What is the term for fungicides that are applied after the initial infection?

Many systemic fungicides can be applied after the initial infection period, before symptoms appear (the latent period); these treatments are called curative .

How important are fungicides?

The diverse array of chemicals currently available is reflected by the several terms used to categorize fungicides. There are presently nine groups of contact fungicides with multisite mode of action. These include some of the first fungicides developed and registered 50 years ago for disease control. There are 47 groups of fungicides with distinct, single-site mode of action. Most of these are mobile in or on the plant, being able to redistribute through translaminar movement on the leaf, systemic or volatile activity, and generally are less toxic to nontarget organisms than fungicides that have multisite, contact activity. Recent registrations of most single-site mode-of-action fungicides are defined as reduced risk in the United States. A major challenge with these fungicides is avoiding decline in efficacy due to development of fungicide resistance. Biopesticides include microbials, nonviable microbials, biochemicals, genetically altered microbials, and transgenic plants producing pesticidal compounds. Minimum-risk fungicides are exempt from pesticide registration in the United States because they contain active ingredients like botanical oils classified as safe. Most are considered suitable for organic production. Plant activators are fungicides that provide disease control without directly affecting pathogens by inducing host resistance.

Where do fungicides deposit?

Fungicide residues can deposit in the soil (Athiel et al., 1995) and may be transferred throughout the food chain. Worldwide, consumers are increasingly aware of the potential environmental and health threats (Draper et al., 2003) linked with the build-up of toxic residues, mainly in food products (Mukherjee et al., 2003).

How are fungicides applied?

Application Methods. Fungicides are applied as dust, granules, gas, and, most commonly, liquid. They are applied to: (a) Seed, bulbs, roots of transplants, and other propagative organs. These treatments are usually done by the seed company. Some treatments need to be done by the grower on-site at the time of planting.

How does economics affect fungicides?

Economics often influence the choice of fungicide and application timing. Expensive fungicides and numerous applications are used on valuable plantings that might incur substantial economic loss in the absence of treatment, such as fruit trees and golf courses. Recognizing that with some diseases crop yield is not impacted when severity is low, an economic threshold is used to determine when fungicide treatment is needed. The crop tolerance level, or damage threshold, can vary depending upon the stage of the crop development when attacked, crop management practices, location and climatic conditions.

How do fungicides affect pathogens?

Many fungicides have targeted activity that imparts high efficacy against specific pathogens, which means low potential for toxicity to humans and other organisms, but also results in a high risk of pathogens developing resistance to the fungicide. A resistant pathogen is less sensitive to the action of the fungicide, which results in the fungicide being less effective or even ineffective. Fungicides that are designed to target specific enzymes or proteins made by fungi do not damage plant tissue, thus they can penetrate and move inside leaves enabling curative properties and increasing the amount of plant tissue protected to more than just where fungicide was deposit when applied. Since the mode of action of these fungicides is so specific, small genetic changes in fungi can overcome the effectiveness of these fungicides and pathogen populations can become resistant to future applications. Disease management strategies that rely heavily upon curative application of fungicides often lead to more resistance problems due to (a) the large size of the pathogen population when the application is made from which resistant individuals are being selected and (b) the difficultly in eradicating a pathogen entirely from inside the plant. Fungicide resistance is covered in more detail in a separate section.

Do fungicides heal symptoms?

Unlike with many diseases of humans and animals, applying fungicides cannot heal symptoms already present, even if the pathogen is killed.

What is the purpose of fungicides in wheat?

Fungicides have been used to reduce mycotoxin contamination in wheat affected by Fusarium head blight, but most fungicides developed so far have not been sufficiently effective to be useful for managing mycotoxins associated with other diseases. Figure 8. Figure 9. Figure 10. Figure 11.

Why do we use fungicides?

Broadly, there are three main reasons fungicides are used: (a) To control a disease during the establishment and development of a crop. (b) To increase productivity of a crop and to reduce blemishes. Diseased food crops may produce less because their leaves, which are needed for photosynthesis, are affected by the disease (Figures 8 - 11). Blemishes can affect the edible part of the crop (Figures 6 and 14) or, in the case of ornamentals, their attractiveness (Figures 12 - 13), which both can affect the market value of the crop. (c) To improve the storage life and quality of harvested plants and produce. Some of the greatest disease losses occur post-harvest (Figures 14 and 15). Fungi often spoil (render unusable) stored fruits, vegetables, tubers, and seeds. A few which infect grains produce toxins (mycotoxins) capable of causing severe illness or even death in humans and animals when consumed. Fungicides have been used to reduce mycotoxin contamination in wheat affected by Fusarium head blight, but most fungicides developed so far have not been sufficiently effective to be useful for managing mycotoxins associated with other diseases.

What is fungicide?

Fungicides are pesticides that prevent, kill, mitigate or inhibit the growth of fungi on plants, but they are not effective against bacteria, nematodes, or viral diseases. Fungicides can be classified based on: Mobility in the plant: Contact vs. mobile (types of systemics).

How does a fungicide work?

Preventive vs. curative: Preventive fungicides work by preventing the fungus from getting into the plant. The preventive fungicide must come into direct contact with the fungus, and they have to be re-applied to new plant tissues (as leaves or needles expand in the spring) or if the product washes off. Curative fungicides affect the fungus after infection. This means they can stop the disease after the infection has started or after first symptoms are observed. Fungicides that can move in the plant can be both preventative and curative.

What is the difference between contact and mobile fungicides?

Mobility in the plant: Contact vs. mobile (types of systemics). Contact fungicides (AKA protectants) are not absorbed by the plant and stick to plant surfaces. They provide a protective barrier that prevents the fungus from entering and damaging plant tissues. Systemic products (also known as penetrants), are absorbed by the plant and can move from the site of application to other parts of the plant. Movement in the plant varies by fungicide, form moving to old and new tissues (amphymobile or true systemic), new growth (acropetally or xylem mobile), moving from the top to the bottom of the leaf surface (translaminar). For more information see the publication “ Fungicide Mobility for Nursery, Greenhouse, and Landscape Professionals .”
