Fungicide Chemicals.
| Class of fungicide chemical | Example of fungicide chemical |
|---|---|
| Ethylene Bis dithiocarbamates | Mancozeb, maneb, nabam, zineb. |
Mancozeb is a broad-spectrum contact fungicide which is labeled for use on many fruit, vegetable, nut, and field crops in Minnesota. It provides protection against a wide spectrum of fungal diseases, including potato blight, leaf spot, scab, and rust.
Elemental Sulphur (i) Sulphur dust Sulphur dust Cosan, Wetsulf, Microsul Sulphur is a contact and protective fingicide, normally applied as sprays or as dust. It is generally used to control powdery mildews of fruits, vegetables, flowers and tobacco.
In general, fungicides that do not move inside a plant are called contact fungicides. These fungicides work by coating the leaf with a protective fungicide barrier that will prevent any spore or piece of fungal mycelium that lands on a leaf from growing and being able to infect the plant.
Fungicides are pesticides that kill or prevent the growth of fungi and their spores. They can be used to control fungi that damage plants, including rusts, mildews and blights. They might also be used to control mold and mildew in other settings.
What Is Systemic And Contact Fungicide? A systemic fungicides is translocated with the plant system before its acts while Contact fungicides doesn't enter the plant, but controls the fungi when it comes in contact with fungi during the application.
While contact fungicide can only kill or eliminate the activities of pathogens, systemic fungicide has an apparent advantage in that they can prevent some fungi infections, when applied and absorbed by the root or leaf of the crops.

Mancozeb has been classified as a contact fungicide with preventive activity. It inhibits enzyme activity in fungi by forming a complex with metal-containing enzymes including those that are involved in the production of ATP.
The current ranking of global sales is: carbendazim, thiophanate, thiabendazole. Morpholine fungicides are best known for their excellent control of cereal diseases, powdery mildew on vegetables and grapes, and sigatoka of banana.
What are the two types of fungicide?
According to the origin, two major groups of fungicides are available: biological and chemical based. The bio-fungicides are composed of living microorganisms like bacteria and fungi as active ingredients and are effective against the pathogens that cause turf disease.
“Triazole fungicides are the most widely used fungicide class in the world,” says Mueller. These locally systemic fungicides move up and down the plant but not in the leaf. Triazole fungicides (Folicur, Domark) inhibit an enzyme that plays a role in fungi sterol production.
- SYSTEMIC FUNGICIDES – Benomyl, carboxin, oxycarboxin,
- Metalaxyl, Carbendazim,- characteristics and use.
- Benzimidazoles.
contact insecticide in British English
(ˈkɒntækt ɪnˈsɛktɪˌsaɪd ) an insecticide that kills on contact, rather than after ingestion or absorption.
Therefore, for effective use Chemical and bi-control agents, one should take a gap of one week, if weather conditions are not favorable or rainfed based system one should take atleast 24 hrs.
Examples of pesticides are fungicides, herbicides, and insecticides. Examples of specific synthetic chemical pesticides are glyphosate, Acephate, Deet, Propoxur, Metaldehyde, Boric Acid, Diazinon, Dursban, DDT, Malathion, etc.
Option C Bordeaux mixture: Also known as Bordo mix, the Bordeaux mixture is a mixture of copper sulphate and quicklime, which is used as a fungicide. This compound is mostly used in vineyards, fruit-farms and gardens for the prevention of infestation of downy mildew, powdery mildew and other kinds of fungi.
Contact Contact pesticides control pests when they come in direct contact with the pest. Systemic Systemic pesticides, when applied to one area of a plant or animal, are transported throughout the plant or animal. They kill all pests which feed on or in that plant or animal.
Use a contact fungicide first or in the tank-mix, if appropriate, to kill spores. Tank-mixing certain fungicides can increase the risk of phytotoxicity. For instance, do not tank-mix sulfur and oil-containing products or spray them within two weeks of each other.
Eradicant fungicides act on the later stages of colonisation (when symptoms are present) and can sometimes also act to suppress spore production. These products also stop or reduce fungal growth, which in turn stops or reduces disease development.
Which is the best systemic fungicide?
Our top systemic fungicide recommendation is Patch Pro Fungicide. Simply mix the fungicide in a pump or hose-end sprayer and apply it to affected plants or for preventative disease control.
Dithiocarbamate fungicides (DTFs) are non-systemic pesticides that have been used since the 1940s to control a number of fungal diseases in various crops and ornamental plants.
Dodine is used as a pre- or post-infection fungicide that is formulated as a liquid flowable concentrate and wettable powder. Dodine has been used to control fungal diseases on apples, cherries, peaches, pears, pecans, strawberries and walnuts.
Dithane® F-45 fungicide is a broad-spectrum fungicide containing the active ingredient mancozeb. It is a contact fungicide with high protectant activity to control a wide range of fungal diseases.
Furadan has been used for 40 years. It functions through contact and systemic activity controlling soil, foliar insects and nematodes in many crops.
Fungicides are used both in agriculture and to fight fungal infections in animals. Chemicals used to control oomycetes, which are not fungi, are also referred to as fungicides, as oomycetes use the same mechanisms as fungi to infect plants.
Mancozeb is a member of the ethylene bisdithiocarbamate (EBDC) group of fungicides, which includes the related active ingredients maneb and metiram. The EBDCs share the common degradate ethylenethiourea (ETU), which has been considered in the Agency's assessments.
A systemic seed treatment fungicide called Vitamax (Carboxin) gives somewhat better control. Seed treatments will not control any soil-borne or airborne fungal diseases that attack older plants such as leaf spots, stalk rots, stem rots, and root rots.
Copper and sulfur are still widely used. Most other fungicides used today are organic compounds and thus contain carbon.
Protectant fungicides are sometimes also called preventative fungicides. Like the name suggests, these are meant to be applied before a fungus takes hold, as they create a protective barrier that stops infection before it starts.

Contact (surface-active) control agents are not absorbed by plant tissue. This type is very common and works by direct contact with the target organism. It is usually sprayed directly onto foliage or bunches where the insect pest or fungus is living or feeding.
Translaminar fungicides (Disease Management Strategies – Purdue Extension) move through the leaf from one side to the other. Xylem Mobile fungicides. fungicides move upward in plants and outward to the periphery of leaves with water through the xylem, the water-conducting tissue of the plant.
- Apply fungicides prior to the development of disease. ...
- Use shorter spray intervals during weather conducive to plant disease. ...
- Apply fungicides before a rain if possible. ...
- Timing of fungicide applications is more important than nozzle type and spray pressure.
Systemic fungicides like Inspire Super, Vangard, Scala, Flint, Sovran, Merivon, Pristine, Luna Sensation, Luna Tranquility, Fontelis, Rubigan, and Rally are highly effective against many tree fruit diseases.
The current ranking of global sales is: carbendazim, thiophanate, thiabendazole. Morpholine fungicides are best known for their excellent control of cereal diseases, powdery mildew on vegetables and grapes, and sigatoka of banana.
Notable examples of systemic fungicides are include benomyl, cyproconazole, azoxystrobin difenoconazole, carbendazim, and propiconazole.
