There are many types of plant diseases, and there are also many types of drugs for preventing and controlling diseases. However, most of the drugs have relatively simple functions. Not only do they need to be sprayed many times, but they cannot completely eradicate the diseases fundamentally, wasting a lot of manpower and material resources, and increasing production investment costs. Today, I recommend an excellent fungicide formula: Difenoconazole·Propiconazole, which prevents and treats diseases cleanly and thoroughly, and the effect is very outstanding.
1. Formula Introduction
Difenoconazole·Propiconazole is a compound fungicide mixed with difenoconazole and Propiconazole. Both are triazole fungicides, and both are ergosterol inhibitor drugs. They have good systemic absorption, strong permeability, and fast bidirectional conduction speed in the plant body. After mixing the two, they have better protection, treatment and eradication of diseases. Especially when the disease is serious, the effect of controlling the disease is more prominent. It is the best fungicide formula to control the expansion and spread of diseases.
2. Main features
(1) Better safety: Propiconazole has strong systemic conductivity, but also has a strong growth inhibitory effect. If the dosage is not controlled properly, it will cause phytotoxicity and seriously inhibit the growth of plants, which makes many dealers and farmers tremble with fear. However, after being mixed with difenoconazole in a certain proportion, the inhibitory effect on crops is not so strong, and the safety is greatly improved.
(2) Better rapidity: Difenoconazole·Propiconazole compound also has good systemic conductivity and permeability. The agent can be absorbed by leaves, stems, roots and other parts. Generally, it can be transmitted to any part of the plant in 1 to 2 hours and kill the bacteria. The disease can be fully controlled in 1 to 2 days, especially in the case of severe disease, the effect is more obvious.
(3) Longer lasting effect: After the agent is absorbed by the plant, it is relatively stable in the plant body. Therefore, the lasting effect of the drug is very long, generally 20 to 30 days, which can significantly reduce the number of times the drug is applied.
(4) Regulating plant growth: Although Difenoconazole·Propiconazole is not as effective as Propiconazole in controlling crop growth, it also has the effect of inhibiting growth, especially in preventing and controlling plant leggy growth. It is also relatively safe. At the same time, the agent is eventually decomposed into amino acids, which provide nutrients for crop growth, enhance leaf photosynthesis, and increase yield.
(5) Wider fungicide spectrum: Difenoconazole·Propiconazole has a wider range of disease control and can be widely used to control dozens of diseases such as powdery mildew, anthracnose, target spot, vine blight, and leaf spot on melons, fruit trees, grain crops, cash crops, flowers, and Chinese medicinal materials. The control effect is better than that of a single agent, and it is not easy to develop drug resistance.
3. Usage method
(1) Control of wheat sheath blight: Use Difenoconazole·Propiconazole, spray at 1500 times when the disease first occurs; spray at 1000 times in the middle of the disease. The amount of water sprayed per mu should be no less than 60 liters by hand, no less than 10 liters by tractor, and no less than 1~2 liters by airplane. Spray the medicine evenly at the internodes at the base of wheat stems.
(2) If used for curative control of grape anthracnose (mid-stage): spray Difenoconazole·Propiconazole 3000 times, with an interval of up to 30 days.
(3) Control of peanut leaf spot: dilute Difenoconazole·Propiconazole 2500 times, spray at the early stage of the disease, and spray continuously 2 to 3 times with an interval of 14 days.
(4) Control of watermelon vine blight: spray Difenoconazole·Propiconazole 5000 times during the watermelon swelling period.
(5) Control of tomato anthracnose and pepper leaf spot: dilute Difenoconazole·Propiconazole 2500 times, spray at the early stage of the disease.
(6) Control of strawberry powdery mildew: spray Difenoconazole·Propiconazole 4000 times at the early stage of the disease.
(7) Rice blast and false smut: Apply the drug at the rice blast stage and heading stage, 20-25 ml/mu, spray on stems and leaves.
(8) Apple leaf spot: Apply the drug at the early stage of the disease, 30-40 ml per mu, and 50-60 ml per mu when the disease is serious, 7-14 days apart, and use it 2-3 times continuously.
Precautions
1. It is particularly effective in controlling newly infected pathogens. Therefore, timely spraying of difenoconazole after rainfall can eliminate the initial source of bacteria and maximize the fungicidal characteristics of difenoconazole. This will play a good control role in the development of diseases in the later stages of growth.
2. Avoid using it with copper preparations. It can be mixed with most insecticides, fungicides, etc., but a mixing test must be done before application to avoid negative reactions or drug damage.
3. Avoid pathogens from developing resistance to difenoconazole. It is recommended that difenoconazole should not be sprayed more than 4 times per growing season. It should be used alternately with other pesticides.
4. In the early stage of the disease, use a low dose with a long interval. When the disease is serious, use a high dose with a short interval; during the epidemic period when the plants grow vigorously, the temperature is suitable, the humidity is high, and there is a lot of rain, a high dose can be used with a short interval, and the number of medications can be increased to ensure the effect of disease prevention and yield increase. It has no inhibitory effect on vegetables.
5. It is toxic to fish and should not pollute water sources. Avoid storage at temperatures below 10°C and above 30°C.
6. Pay attention to safety protection when using the medicine. If the liquid medicine splashes into the eyes, rinse the eyes with clean water for at least 10 minutes immediately; if taken by mistake, go to the hospital for symptomatic treatment immediately. This medicine has no special antidote. The remaining liquid medicine and washing wastewater cannot pollute fish ponds, pools and water sources.
7. The safe interval on watermelons is 7 days, and the maximum number of uses per season is 3 times.
