Downy mildew, blight, and late blight are considered to be the diseases that spread the fastest, cause the most serious harm, and are the most difficult to control, especially on cucumbers, melons, grapes, potatoes, peppers and other crops, causing huge losses every year. Today, I would like to recommend to you an excellent agent for preventing and treating these diseases--fluorobacteria and propamocarb, which can prevent, treat and eradicate downy mildew, blight and late blight.
1. Introduction to pharmaceuticals
Fluoride·propamocarb is a fungicide compounded from 62.5 g/L fluopyram + 625 g/L propamocarb hydrochloride. Fluopyram is an amide fungicide with strong permeability and good inhibitory effect on all major forms of Oomycete pathogens.
Propamocarb hydrochloride is a multi-action site fungicide with systemic properties and high activity both inside and outside the plant. It can strongly inhibit the formation of spores and zoospores, inhibit the growth and proliferation of pathogenic hyphae, and has preventive and therapeutic effects on diseases.
When the two are mixed, they have both protective and therapeutic effects. It has stable and good control effect on diseases caused by Oomycetes, especially on diseases caused by downy mildew and phytophthora.
2. Main features
(1) Broad bactericidal spectrum: This drug has a good preventive and therapeutic effect on diseases caused by various pathogens such as Aspergillus, Aspergillus, Phytophthora, Pseudomonas, and Fusarium, such as downy mildew, late blight, epidemic, sudden collapse, and black shank disease.
(2) Strong permeability: This agent has strong permeability and can penetrate from the front of the leaves to the back of the leaves to kill the pathogens on the back of the leaves.
(3) Thorough treatment: This agent has a very good inhibitory effect on the release and movement of zoospores, hyphae germination and growth, and sporulation at all stages. It has protective and therapeutic effects, and the treatment is more thorough.
(4) No cross-resistance: This agent mainly exhibits bactericidal activity by acting on specific proteins between the cell membrane and cytoskeleton. This bactericidal mechanism is completely different from all currently known Oomycete fungicides. There is no cross-resistance.
(5) Long duration of effect: This agent can exist in the body of crops for a long time to achieve the purpose of continuous sterilization. The duration of effect is longer, and generally the duration of effect can reach more than 15 days.
(6) Flexible application: Because the agent has strong permeability and systemic conductivity, it can be used for spraying and root irrigation.
3. Use crops
The agent can be widely used in cucumbers, tomatoes, eggplants, peppers, watermelons, zucchini, grapes, apples, pears, strawberries, potatoes, lettuce, tobacco and other crops.
4. Prevention and control objects
Mainly used to prevent and control damping-off, downy mildew, blight, black shank, late blight and other diseases.
5. Use technology
When raising seedlings of tomatoes, cucumbers, peppers, eggplants, watermelons and other crops, you can use 1000 times of 687.5/liter Fluorobacterium Propamidiocarb suspension to irrigate the roots. It can effectively prevent and control the occurrence of downy mildew, epidemic diseases and other diseases throughout the seedling stage, and has a long-lasting effect.
In the early stages of diseases such as downy mildew and late blight on cucumbers, melons, grapes, tomatoes, and potatoes, 687.5/L fluorobacteria·propamocarb suspension can be sprayed 900 to 1000 times. Spraying once every 7 days for 2 to 3 times can quickly control the expansion and spread of the disease, and ultimately eradicate the disease completely.
