Which crops is triadimefon suitable for? A detailed explanation of its scope of use

Triadimefon can be sprayed on all crops or fruit trees. It is a low-toxicity fungicide, has moderate toxicity to fish, and is harmless to bees and birds. After being absorbed by various parts of the plant, it can be translocated within the plant. It has preventive, eradicative, and curative effects against rust and powdery mildew. It is effective against diseases of many crops, such as corn round spot disease, cereal downy mildew, wheat leaf blight, pineapple black rot, corn head smut, and others.

I. Methods of use

1. Cereal head smut, rust, powdery mildew, downy mildew, etc. For cereal head smut, dress 100 kg of seed with 30 g of active ingredient (200 g of 15% wettable powder); for rust, powdery mildew, and downy mildew, at the early stage of disease, use 8.75 g of active ingredient per mu (35 g of 25% emulsifiable concentrate), and in severe cases use 15 g of active ingredient (if using 25% emulsifiable concentrate, 60 g is needed), diluted with 75-100 kg of water for spraying.

2. Corn and sorghum head smut To control corn head smut, dress each 100 kg of seed with 533 g of 15% wettable powder. For sorghum head smut, dress each 100 kg of seed with 266-400 g of 15% wettable powder.

3. Cucurbit powdery mildew In the field, spray 1-2 times with a 5000-fold dilution of 25% wettable powder; in the greenhouse, spray 1-2 times with a 1000-fold dilution of 25% wettable powder. Bean rust At the early stage of disease or upon reinfection, spray 1-2 times with a 2000-fold dilution of 25% wettable powder.

II. Characteristics of triadimefon

Triadimefon is a highly effective, low-toxicity, low-residue, long-lasting, strongly systemic triazole fungicide. After being absorbed by various parts of the plant, it can be translocated within the plant. It has preventive, eradicative, and curative effects against rust and powdery mildew. It is effective against diseases of many crops, such as corn round spot disease, cereal downy mildew, wheat leaf blight, pineapple black rot, corn head smut, and others. It is relatively safe for fish and birds. It is harmless to bees and natural enemies. The fungicidal mechanism of triadimefon is extremely complex; it mainly inhibits the biosynthesis of ergosterol in the fungal body, thereby inhibiting or interfering with the development of the fungal appressorium and haustorium, the growth of hyphae, and the formation of spores. Triadimefon has very strong activity against certain pathogens in vivo, but its effect in vitro is very poor. Its activity against hyphae is stronger than against spores. Triadimefon can be mixed and used on the spot with many fungicides, insecticides, herbicides, and others.

Although triadimefon can act on most crops, it has slight toxicity, so be careful not to get it into your eyes, and remember to wash your hands after spraying triadimefon.
