Core introduction to the text: Experience in the aspect of green plant maintenance on the best medication for downy mildew, let's understand it together next.
What is the best medication for downy mildew
Common medications for downy mildew include copper hydroxide, copper resinate, propamocarb, diniconazole, triadimenol, zineb, pyrimidine nucleotide antibiotics, mancozeb, dimethomorph, triadimefon, propiconazole, tebuconazole, myclobutanil, metalaxyl-M, thiram, zineb, pyraclostrobin, maneb, flumorph, aluminum trisulfate, cymoxanil, pyrimidine nucleotide antibiotics, mancozeb, and polyoxin.
What is downy mildew
Downy mildew, also known as yellow leaf disease, scorched leaf disease, and dry leaf disease, is the most common and severe disease that affects crops such as cucumbers, melons, grapes, watermelons, and Pak Choi, and is the most difficult to control.
Once our crops are infected with downy mildew, yield reduction is inevitable, and it is difficult to eradicate. Therefore, choosing an efficient fungicide is the most effective way to quickly control downy mildew. If downy mildew is indeed detected, it is necessary to use a special-purpose drug for spraying to achieve control.
What medication is effective for treating downy mildew
Fluopyram + PropamocarbThis formula is a combination of fluopyram and propamocarb, with the commercial name "Silverfall." Fluopyram is a therapeutic fungicide, while propamocarb is a systemic fungicide.
When used together, they provide both protective and therapeutic effects, with high activity, long duration, strong systemic action, and flexible application timing.
Fluopyram + Propamocarb is a special fungicide for controlling downy mildew. In the early stages of downy mildew, 60-75 ml of 68.75% Fluopyram + Propamocarb suspension can be diluted in 30-50 kg of water and sprayed evenly. This can quickly control the spread of the disease.
Pyraclostrobin + FluxapyroxadThis formula is a combination of pyraclostrobin and fluxapyroxad, with the commercial name "Zengweiyingbei." Fluxapyroxad has protective, therapeutic, and sporulation-inhibiting effects on the pathogen, especially against Oomycete diseases with excellent fungicidal activity.
Pyraclostrobin has excellent fungicidal activity against Oomycete diseases and early blight. When used together, they have systemic apical transport effects and protect new tissues.
For controlling downy mildew in cucumbers, 27-33 ml of 31% Pyraclostrobin + Fluxapyroxad suspension can be diluted in 30-40 kg of water and sprayed evenly in the early stages of the disease.
For controlling downy mildew in grapes, 1500 times稀释 of 31% Pyraclostrobin + Fluxapyroxad suspension can be sprayed, which can quickly control the further harm and spread of downy mildew.
Metalaxyl-M + MancozebThis formula is a combination of metalaxyl-M and mancozeb, with the commercial name "Mold Enemy." Mancozeb in the formula is a protective fungicide. Since it does not contain manganese ions that may cause phytotoxicity to crops, it is safer for crops.
Metaxyl-M is a new systemic fungicide that has both protective and therapeutic effects on diseases caused by Oomycete pathogens. When used together, the synergistic effect is very significant, and it is effective against downy mildew on crops such as cucumbers, grapes, and Pak Choi.
In the early stages of downy mildew, 120-150 grams of 72% Metalaxyl-M + Mancozeb wettable powder can be diluted in 30-50 kg of water and sprayed evenly, which can quickly control the further harm and spread of the disease.
Experiments show that using 68.75% Fluopyram + Propamocarb suspension at 1500 times, 31% Pyraclostrobin + Fluxapyroxad suspension at 1500 times, and 72% Metalaxyl-M + Mancozeb wettable powder at 800 times can control downy mildew in grapes. The efficacy is 90% after 3 days and still reaches over 80% after 20 days. Alternating the use of these three fungicides can effectively prevent the occurrence of downy mildew in grapes.
The comprehensive method described above for the best medication for downy mildew aims to solve your green plant problems.
