Propineb is a protective fungicide with a broad spectrum of activity, effectively preventing and controlling a variety of diseases. So, what diseases does propineb treat? Let's take a look.
I. What diseases does propineb treat?
1. Propineb is highly effective against box mold, early blight, late blight, leaf spot (such as black spot and brown spot), anthracnose , black spot, and ring rot. It also provides protective fungicide action with both rapid and long-lasting effects against various crop diseases, including apple blotch, Chinese cabbage downy mildew, cucumber downy mildew, tomato early blight, tomato late blight, and grape downy mildew.
2. Propineb has a long residual effect and is safe for humans, livestock, crops, and other beneficial organisms. Because it does not contain manganese, which can cause phytotoxicity to crops, it has low toxicity and is safer. According to China's pesticide toxicity classification standards, propineb is a low-toxicity fungicide. It is harmless to bees and users, and can be used during flowering and at all stages of crop growth.
II. Instructions for use of propineb
Propineb is a protective fungicide and must be sprayed before or at the onset of disease.
Do not mix with copper-based or alkaline agents. If copper-based or alkaline agents have been sprayed, wait one week before using this product.
Application method: Apply the pesticide before or at the early stage of disease. Depending on the severity of the disease, apply the pesticide 3-4 times, spraying once every 5-7 days.
1. Grape downy mildew
When the disease first appears, it is necessary to spray with a 70% wettable powder solution diluted 400-700 times, about 3 times, with an interval of about 7 days.
2. Citrus anthracnose
In the early stages of the disease, spray with a 70% wettable powder diluted 600-800 times.
3. Tomato
(1) Early blight of tomatoes: Early blight usually occurs when tomatoes are just beginning to bear fruit. Use 125-190 grams of 70% wettable powder per mu, diluted with water and sprayed. Spray once every 5-7 days, and the effect can be seen after 2-3 sprays.
(2) Late blight of tomatoes: After late blight appears, diseased plants should be removed before spraying. Use 150-220 grams of 70% wettable powder, spray about 2-3 times, with an interval of 5-7 days between each application.
4. Cucumber downy mildew
After transplanting cucumbers in open fields, they are prone to disease in humid and warm environments. Before spraying, remove diseased leaves and use 150-215 grams of 70% wettable powder diluted in water for spraying. A total of 3 sprays are required, one spray every 5-7 days. To strengthen prevention, spray once after rain.
5. Apple leaf spot disease
This disease easily infects young leaves. When the disease occurs, spray with a 600-700 times dilution of 70% wettable powder, spraying 3-4 times consecutively, once every 7 days, and spraying again in autumn.
6. Tobacco-borne red spot disease
In the early stages of the disease, spray with a 500-700 times diluted solution or 90-130 grams of 70% wettable powder, about 3 times, with a longer interval, about 10 days.
7. Mango anthracnose
During the mango flowering period, when rainfall is abundant and disease is more likely, begin spraying with a 500-fold dilution of 70% wettable powder. Spray a total of 4 times, with an interval of 10 days between each spray.
