Cyproconazole is a highly efficient, broad-spectrum, systemic, and low-toxicity triazole fungicide. It has protective and curative effects and can be used to control various crop diseases caused by ascomycetes, basidiomycetes, and deuteromycetes. So, when should cyproconazole be used? Let's explore.
When to Use Cyproconazole?
1. When to Use Cyproconazole
Cyproconazole is effective against several diseases in different crops. Here are specific guidelines for its use:
-
Cucumber (Powdery Mildew, Black Spot, Anthracnose): Begin spraying at the early onset of disease. To prevent resistance, alternate with other types of fungicides every 7 to 10 days, applying 3 to 4 times consecutively. Use 12% emulsifiable concentrate (EC) or 12.5% EC at 2000 to 2500 times dilution, or 25% EC at 4000 to 5000 times dilution, or 40% wettable powder (WP) at 6000 to 8000 times dilution, uniformly spraying. Alternatively, apply 30 to 40 milliliters of 12% EC or 12.5% EC, or 15 to 20 milliliters of 25% EC, or 10 to 12 grams of 40% WP per mu, mixed with 60-90 kilograms of water, uniformly sprayed.
-
Watermelon, Cantaloupe, Pumpkin, Bitter Gourd, Winter Melon (Powdery Mildew, Anthracnose): Spray promptly at the early stage of the disease. Alternate with other types of fungicides, spraying once every 7-10 days, for 2-4 times. Use the same dilution rates as for cucumber powdery mildew.
-
Solanaceous Vegetables (Powdery Mildew, Anthracnose, Leaf Spot): Spray promptly upon disease detection, spraying once every 10 days. Alternate with other types of fungicides, spraying 2-4 times consecutively. Use the same dilution rates as for cucumber powdery mildew.
-
Celery (Leaf Spot): Spray at the early onset of the disease. Alternate with other types of fungicides, spraying once every 7-10 days, for 2-4 times. Use 12% EC or 12.5% EC at 1500-2000 times dilution, or 25% EC at 3000 to 4000 times dilution, or 40% WP at 5000 to 6000 times dilution, uniformly sprayed.
-
Leguminous Vegetables (Powdery Mildew, Rust, Anthracnose): Begin spraying at the early onset of the disease. Alternate with other types of fungicides to prevent resistance, spraying once every 7-10 days, for 3-4 times. Use the same dilution rates as for celery leaf spot.
-
Asparagus (Stem Blight, Rust): Spray promptly upon disease detection. Alternate with other types of fungicides, spraying once every 7-10 days for 2-3 times. Use the same dilution rates as for celery leaf spot.
-
Colocasia esculenta (Anthracnose): Start spraying as soon as the disease is found. Alternate with other types of fungicides, spraying once every 10 days, continuing for 3-5 times. Use the same dilution rates as for celery leaf spot.
-
Peanut (Leaf Spot, Rust): Spray at the early onset of disease spots. Alternate with other types of fungicides to prevent resistance, spraying once every 10 days for 2-3 times. Use 20-30 milliliters of 12% EC or 12.5% EC, or 10-15 milliliters of 25% EC, or 6-8 grams of 40% WP per mu, mixed with 30-45 kilograms of water, uniformly sprayed.
2. Precautions for Using Cyproconazole
When using cyproconazole, observe the following precautions:
-
Respect the intervals for pear trees (7 days), grapes (21 days), cucumbers (3 days), and lychees (7 days). Use the fungicide no more than 3 times per season (or year).
-
Cyproconazole is toxic to bees and silkworms. Avoid affecting surrounding bee colonies during application. Do not use near flowering plants, silkworm chambers, or mulberry orchards. Prevent contamination of water sources. Do not clean spraying equipment in rivers or ponds.
-
Wear protective clothing and gloves when handling cyproconazole. Avoid inhaling the spray. Do not eat or drink during application. Wash hands and face immediately after application.
-
Pregnant and lactating women should avoid contact with cyproconazole.
-
Rotate with fungicides with different mechanisms of action to delay resistance development.
-
Do not mix cyproconazole with alkaline pesticides or other substances.
Conclusion
The above information provides detailed guidelines on when to use cyproconazole. Cyproconazole has a long duration of efficacy, is relatively safe for crops, stimulates growth, and has strong systemic and curative effects against diseases.
