Cyazofamid: A Professional Killer of Downy Mildew

Cyazofamid is a member of the class of imidazoles carrying dimethylsulfamyl, cyano, chloro and 4-tolyl substituents at positions 1, 2, 4 and 5 respectively. A fungicide used mainly for controlling Oomycete and Plasmodiophora diseases on potatoes and tomatoes.

Cyazofamid has a role as a mitochondrial cytochrome-bc1 complex inhibitor and an antifungal agrochemical. It is a member of imidazoles, an organochlorine compound, a nitrile, a member of sulfamides, a sulfonamide fungicide and an imidazole fungicide.

Introduction of Properties of Cyazofamid

Cyazofamid is known as a super protective fungicide, which has special effects on diseases such as downy mildew, blight, root swelling, and sudden death. The mechanism of action is to block the electron transfer of mitochondrial cytochrome bc1 complex in oomycetes to interfere with energy supply. Its binding site is the Q center of the enzyme, known as QiI (Quinone inside Inhibitors) fungicides, which have no cross resistance with other fungicides. But it cannot be mixed with alkaline agents.

Cyazofamid is resistant to rainwater erosion and receives rainfall 2 hours after application, without affecting its efficacy. After use, there are no drug stains on the surface of fruits and vegetables, improving their quality and increasing profits. It can increase the color of crop leaves, prolong crop growth and harvest time, and increase yield. And it is harmless to human, animal, fish, vector insects, all plants, as well as the environment and soil.

History of Cyazofamid

Cyazofamid is a new generation of phenylimidazole fungicides developed exclusively by Ishihara Industries in Japan and jointly developed with BASF. It was first registered in England in 2001 and registered in Japan in April of the same year. It has been in use for over twenty years now. In 2013, the first registration of Cyazofamid in China was approved. However, due to the large amount of wastewater generated by Cyazofamid, 1 ton of Cyazofamid needs to generate 60-80 tons of acid and DMF solvent wastewater, resulting in high post-treatment costs and a relatively low overall operating rate.

What are the advantages of Cyazofamid?

1. Cyazofamid can comprehensively and effectively prevent and control the damage and transmission of pathogenic bacteria in the oomycetes class during all growth stages: it can not only inhibit the germination of oomycetes and zoospores, but also inhibit and prevent the movement of zoospores. At the same time, it can also inhibit the formation of mycelium, zoospore sacs, and oospore sacs, thereby comprehensively preventing and controlling diseases in the oomycetes class.
2. Long lasting effect: Cyazofamid is currently one of the fungicides that has a longer lasting effect on the prevention and control of lower fungi such as Aspergillus and Phytophthora. Spraying it on crops can provide long-lasting protection from disease infection, which is 5-7 days longer than other fungicides on the market and can reduce the frequency of crop control.
3. The mechanism of action is unique, and it has no interactive resistance with other fungicides. It has a better control effect on oomycetes that have developed resistance to existing fungicides. It mainly acts on the energy metabolism system of pathogenic bacteria, blocking the electron transfer of mitochondrial cytochrome bc1 complex in the body of oomycetes to interfere with energy supply and kill pathogenic bacteria. It has no interactive resistance with other fungicides.
4. Super resistant to rainwater erosion and disease prevention effect: After spraying on crops, it can combine with the surface tissue of crops to form a dense protective film, resistant to rain and wind erosion, and effectively block the infection of pathogenic spores, thereby preventing the infection of diseases in the class of oomycetes.
5. Wide prevention and control spectrum: It can effectively prevent and control all fungal diseases in the class of oomycetes, such as downy mildew, sudden fall disease, downy blight, phytophthora, and stem rot disease caused by rot fungi.
6. Highly safe for crops: Cyazofamid can be promoted on all crops without considering pesticide damage and adverse reactions to crops, and can be promoted and applied during the flowering period.
7. Highly safe for human: Cyazofamid is extremely low toxicity, has short safety interval, can be harvested and consumed within two to three days after medication, and is recommended for use as a fungicide in green food vegetables.

Attention When Using

1. Shake well before use.
2. It is ineffective in preventing diseases other than oomycetes. If other diseases occur simultaneously, it should be mixed with other pesticides.
3. Highly toxic to aquatic animals, pay attention to protection.
4. To ensure efficacy, it must be used before or in the early stages of the disease, with an interval of 7-10 days between application and 3-4 times per season for crops.
5. To ensure the efficacy, please evenly spray the liquid medicine to the front and back of all leaves of the plant.
