Why does the new shoot of the rose need to be sprayed with pesticide immediately?
This pot of rose initially had leaf spot disease, so I gave it a major pruning. Why did I prune it? Because its leaf spot disease was extremely severe. If I didn't prune it, I estimated that the whole plant might not have been saved, so I gave it a severe pruning.
After pruning, the leaves that grew out were very healthy and vigorous, showing no signs of leaf spot disease. However, we cannot let our guard down at this point. We still need to continue treating it because these bacteria could be lurking around, waiting for the right opportunity to continue attacking the rose.
After the rose with leaf spot disease grows new buds, we need to promptly carry out another round of preventive measures to ensure it remains healthier and safer, not prone to recurrence. The current prevention method is to do another round of fungicide treatment.
We still use the same medicine as before to spray it once, which is the metalaxyl in the rose care package. This is a fungicide specifically designed for leaf spot disease and powdery mildew, with very strong fungicidal properties.
Both diseases are caused by bacterial infections and are specifically targeting roses. We dilute it with water at about 1000 times and spray it directly. I have prepared it in advance, already mixed with metalaxyl.
Now, spray this on the leaves, making sure to cover both the front and back of each leaf to effectively eliminate these bacteria and prevent them from attacking the rose again. Also, spray the surface of the pot.
Completely eliminate these bacteria. Don't just look at how well it is growing now. If you don't take this step, the rose will be even harder to treat if it gets sick again. When we find that our rose has developed a severe leaf spot disease, we should not think of treating it with medicine because it won't have much effect, even if it is completely cured.
The plant's vitality in the later growth will also be very poor because those branches will have a long recovery period before they can continue to grow. Pruning directly is the most ideal approach. After pruning, new leaves will grow out.
The above explanation about why the new shoot of the rose needs to be sprayed with pesticide immediately hopes to bring a little help to your life!
