Hexaconazole is a new generation of high-efficiency triazole fungicides developed after triadimefon, diniconazole, tebuconazole, difenoconazole and propiconazole. The biological activity and bactericidal mechanism of hexaconazole are similar to those of triadimefon and triadimenol. It has the characteristics of broad antibacterial spectrum, strong permeability and systemic conductivity, and good preventive and therapeutic effects. The mechanism of action is to destroy and prevent the pathogenic bacteria ergot The biosynthesis of sterols prevents the formation of bacterial cell membranes and eventually causes the death of bacteria. Hexaconazole can effectively control diseases caused by Ascomycetes, Basidiomycetes and Deuteromycetes, especially for diseases caused by Basidiomycetes and Ascomycetes, such as powdery mildew, rust, scab, brown spot, anthracnose, sheath blight , Rice smut, etc. have good preventive and therapeutic effects, but hexaconazole is ineffective against oomycetes and bacteria. Applied on suitable crops according to the recommended dose, it is environmentally friendly and safe for crops, but sometimes it is phytotoxic to some apple varieties.

Features of Hexaconazole 

The main dosage forms of hexaconazole in China are water dispersible granules, suspension concentrates, emulsifiable concentrates, and microemulsions. Abroad, there is Anfu (5% hexaconazole suspension concentrate) registered by British Syngenta, which is mainly registered on pear tree scab, apple leaf spot, rice sheath blight, and peach brown rot. Spray 1000-1500 times of 5% hexaconazole suspension to control pear tree scab and apple spot defoliation, and prevent and control peach tree brown rot 800-1000 times. Control rice sheath blight 5% suspension concentrate 60~100 grams. According to reports, hexaconazole can also be used to prevent grape powdery mildew and white rot at 10-15 mg/kg, and apple powdery mildew and rust at 10-20 mg/kg. In addition, hexaconazole has a good therapeutic effect on coffee rust. The dosage per mu is 2 grams of active ingredients, and the effective ingredients for the prevention and treatment of peanut leaf spot are 3-4.5 grams per mu. Hexaconazole can be mixed with other conventional fungicides. When diluting or applying pesticides, you should abide by the rules for the safe use of pesticides and wear necessary protective equipment.

The role and effect of hexaconazole

Hexaconazole is a triazole fungicide, a sterol demethylation inhibitor, and has broad-spectrum protective and therapeutic effects on diseases caused by fungi, especially Basidiomycota and Ascomycota. Destroy and prevent the biosynthesis of ergosterol, an important component of the cell membrane of bacteria, resulting in the inability of the cell membrane to form and the death of the bacteria. Has systemic, protective and therapeutic activity.

Applications of Hexaconazole

Hexaconazole is mainly used for powdery mildew and scab on apples, Staphylococcus and hookworm on grapes. Camelina on coffee, Cercospora on peanuts. According to the development of the market, the share of hexaconazole emulsifiable concentrate has been further compressed, 5% microemulsion has become the mainstream of the market, and 5% suspending agent has become a new target. High content has gradually become the trend of market development. The main market direction of high-content hexaconazole is concentrated in the fruit and vegetable market, and the low-content hexaconazole is mainly concentrated in field crops. In the fruit and vegetable market, bananas, citrus, apples and pears are mainly used. The control targets are banana leaf spot, citrus scab, pear scab, and apple leaf spot. The low content is mainly aimed at the rice, wheat and vegetable markets, mainly 5% hexaconazole suspension concentrate and microemulsion. How to use: Foliar spray. 10-20mg/L, to prevent grape powdery mildew, black rot, apple powdery mildew, scab; 20-50mg/L, to prevent coffee rust and peanut leaf spot. (1) Grapes. Hexaconazole has outstanding control effect on powdery mildew on grape leaves and clusters, and its effect on black rot is higher than other agents. The use of 15-20mg/L is suitable for the year when the virus is severely prevalent. (2) Apples. 10-20mg/L alone or mixed with dithiocarbamate has a good control effect on apple scab and powdery mildew, and is also very effective on apple gum rust. Spray with a concentration of 33.3-62.5mg/kg to prevent and control apple spot defoliation. (3) Peanuts. On peanuts, no matter hexaconazole single agent or the mixture with low concentration of chlorothalonil is effective in controlling early and late leaf spot, the effect is better than chlorothalonil. (4) COFFEE. Curative activity against coffee rust with long duration. In the year when the disease is prevalent, the effect of spraying 3 times with 30g/hm2 is as effective as that of copper preparation 5 times, slightly better than 250g/hm23 times of triadimefon. The same control effect of 250g triadimefon can be obtained with the effect of 10g dose. (5) pears. Dilute with 5% hexaconazole microemulsion to a concentration of 40-50 mg/kg and spray to prevent and treat pear black heart disease.
