Triadimefon belongs to the triazole class of fungicides with broad systemic absorption. It is commonly used as a foliar spray for cereal and fruit crops, effectively preventing various diseases. Let's explore what diseases triadimefon treats, its functions, and applications.
Triadimefon: Diseases Treated
Triadimefon is effective against several fungal diseases on various fruit trees, including but not limited to:
-
Black spot
-
Powdery mildew
-
Rust
-
Anthracnose
-
Leaf spot
-
Brown rot
-
Alternaria leaf spot
-
Phomopsis blight
-
Botryosphaeria canker
-
Scab
For example:
-
On pear trees: black spot, powdery mildew, rust, anthracnose, leaf spot, brown spot.
-
On apple trees: apple scab, powdery mildew, rust, leaf spot, brown spot, anthracnose.
-
On peach trees: brown rot, powdery mildew, anthracnose.
-
On apricot trees: shot hole disease (Coryneum blight), black spot.
-
On plum trees: plum pox virus, anthracnose.
-
On grapevines: black rot, anthracnose, powdery mildew, brown rot.
-
On hawthorns: powdery mildew, leaf spot, black spot.
-
On walnut trees: powdery mildew, anthracnose, brown spot.
-
On chestnut trees: powdery mildew, anthracnose.
-
On persimmon trees: leaf spot, black spot, anthracnose.
-
On Chinese wolfberry: powdery mildew, anthracnose.
-
On pomegranate trees: black spot, brown spot, anthracnose, scab.
Triadimefon: Functions and Applications
1. Functions
Triadimefon is a systemic triazole fungicide with protective and curative activity. It inhibits the biosynthesis of ergosterol in fungal pathogens, showing effective control against ascomycetes and basidiomycetes.
2. Longevity and Safety
Triadimefon has a long duration of action and is relatively safe for crops. It also stimulates plant growth to some extent and inhibits the biosynthesis of ergosterol, a sterol component of fungal membranes.
3. Preventive and Curative Effects
Triadimefon exhibits strong systemic absorption and high efficacy in both prevention and treatment of fungal diseases.
Triadimefon: Incompatible Mixtures
Triadimefon should not be mixed with alkaline pesticides such as benzimidazole and sulfur compounds. Mixing should be avoided to prevent phytotoxicity.
Important Considerations
Triadimefon offers high cost-effectiveness, where 40% concentration can achieve up to 60% efficacy. It is rapidly absorbed by plants within an hour after application, promoting dark green foliage and robust plant growth, thereby enhancing yield.
When using triadimefon:
-
Respect the interval periods for crops: 7 days for pears, 21 days for grapes, 3 days for cucumbers, and 7 days for lychees.
-
A maximum of 3 applications per season (or year) is recommended.
-
Avoid application during flowering periods of nearby plants, silkworm chambers, and mulberry orchards.
-
Do not wash application equipment in ponds or water bodies to prevent contamination.
-
Wear protective clothing and gloves during application. Avoid inhalation and contact with skin. Do not eat or drink during application. Wash hands and face promptly after application.
-
Pregnant and lactating women should avoid contact with this pesticide.
Rotation with pesticides having different mechanisms of action is advisable to delay resistance.
Conclusion
Triadimefon is a powerful systemic fungicide with excellent preventive and curative properties against various fungal diseases in fruit trees. It enhances plant growth without harming fruit surfaces and is non-toxic to bees.
