Difenoconazole, tebuconazole, propiconazole, econazole and flusilazole are also triazole fungicides. What are the differences?
1. Bactericidal broad-spectrum comparison
Difenoconazole
Difenoconazole is a fungicide with relatively high safety among triazole fungicides. It is widely used in fruit trees, vegetables, rice, peanuts and other crops to prevent and control scab, black pox, white rot, and spot Deciduous disease, powdery mildew, brown spot, rust, stripe rust, head blight, etc.
Tebuconazole
Widely used in a variety of fungal diseases on wheat, rice, peanuts, vegetables, bananas, apples, pears, corn sorghum and other crops, mainly to control powdery mildew, rust, scab, blight, root rot, leaf mold And various spot diseases, etc., especially for leaf spot diseases of solanaceous vegetables, the control effect is better.
Propiconazole
Widely used in banana, wheat, rice, lychee, vegetables, grapes, watermelon, barley, corn; mainly control leaf spot, wilt, anthracnose, powdery mildew, leaf mold, etc.
Epoxiconazole
Widely used in grains, soybeans, fruits and vegetables, against leaf spot, powdery mildew, rust on bananas, onions, garlic, celery, kidney beans, melons, asparagus, peanuts, sugar beets and other crops, as well as anthracnose and white rot on grapes Diseases and other diseases have a good control effect.
Flusilazole
With strong permeability, it can prevent diseases caused by ascomycetes, basidiomycetes and some fungi. It has good control effects on powdery mildew, scab, leaf spot and rust of crops, and has obvious effect on the control of pear scab.
Sorting of bactericidal spectrum: difenoconazole > tebuconazole > propiconazole > flusilazole > flueconazole
2. Systemic comparison
Difenoconazole: It has relatively good systemic property, but its systemic property is relatively low among similar triazole fungicides, it cannot be transmitted across leaves, and it moves poorly in xylem.
Tebuconazole: It is a high-efficiency systemic fungicide, which can be used in seed treatment agents and foliar sprays, with high activity and long-lasting effect.
Propiconazole: It has a strong systemic effect, high activity, long duration, and strong conductivity. It can be absorbed by roots, stems, and leaves, and can quickly conduct upwards in the plant body.
Epoxiconazole: It also has a strong systemic effect, and can be quickly absorbed by plants and transmitted to the affected parts, so that the disease infestation can be stopped immediately, and local application can be thoroughly controlled.
Flusilazole: a strong osmotic systemic fungicide, absorbed by stems and leaves, and moved in xylem. It can be moved from the sprayed part to other parts and redistributed.
Systemic order: flusilazole ≥ propiconazole > flucyconazole ≥ tebuconazole > difenoconazole
3. Targeted comparison of sterilization
Difenoconazole: It has a good effect on anthracnose, white rot, leaf spot, powdery mildew, and rust.
Tebuconazole: It has a strong eradicating effect and is more obvious in increasing the yield of cereal crops. It is better to mainly target spots (leaf spots, brown spots, etc.).
Propiconazole: a broad-spectrum fungicide, has protective and therapeutic effects, and is systemic. It is mainly used to prevent and control leaf spot on bananas, and it is mostly used in the early stage of disease.
Epoxiconazole: It is widely used in fields and southern fruit trees, and it is better against rust and leaf spot of cereals and beans.
Flusilazole: the fungicide with the highest activity, it has obvious effect on scab.
4. Quick-acting comparison
Triazole fungicides have strong systemic conductivity, so the absorption and effect are relatively fast.
Quick-acting property: flusilazole > propiconazole > flucyconazole > tebuconazole ≥ difenoconazole
5. Comparison of plant growth inhibition
Triazole fungicides can inhibit the synthesis of gibberellin in plants, resulting in slow growth of plant tops and shortened internodes.
Inhibition intensity: econazole> flusilazole> propiconazole> diniconazole> triadimefon> tebuconazole> mycloconazole> penconazole> difenoconazole> tetrafluconazole
6. Comparison of certain bacteria
Effect on anthracnose: difenoconazole > propiconazole > flusilazole > myclobutanil > diniconazole > econazole > penconazole > tetrafluconazole > triadimefon
The effect on leaf spot: econazole>propiconazole>butaconazole>difenoconazole>tebuconazole>mycloconazole
Effect on scab: flusilazole > myclobutanil ≥ difenoconazole > econazole > tebuconazole > propiconazole
