Rose love to attract insects, give you 3 strokes, let it get rid of the "medicine jar" title...

If you want to say that the most popular bugs in flowers should be the rose, the rose blossoms for a long time, and the fragrance of the flowers is very strong, at this time there will inevitably be some small flying insects or disease problems. Today, Huahua comes to give you a few tricks to deal with the common diseases of Chinese rose, so that it can get rid of the title of "medicine jar".

1. Black rot

Black rot is a common disease of Chinese rose, and many rose flowers die because of this disease. The phenomenon of black rot is that there are some small dark brown spots on the leaves, and slowly these spots will grow bigger and bigger, until they spread to the whole rose, and finally the rose will begin to lose its leaves.

We can prevent the black rot of rose in advance, and it is best to spray Dysen zinc every half a month in spring and summer, which can reduce the chance of black rot. If it has already appeared, do not panic, first remove all the leaves with black rot, and then spray with carbendazim and other disinfection solution, so that there will be no problem for a week.

two。 Powdery mildew

Powdery mildew is also a common disease of rose. Powdery mildew is similar to black rot, that is, the leaves are covered with powdery mildew, and in serious cases, the whole leaves will be pasted, so how can rose flowers without photosynthesis grow exuberantly.

When powdery mildew first appears on the leaves, it is usually concentrated on the edge and back, and then slowly spreads to the whole leaf, sometimes even on the petals. Powdery mildew usually occurs more frequently in spring and autumn, when it appears, we can spray it with the same disinfection solvent as for black rot, but because powdery mildew adheres to the leaves, some viscous liquids such as detergent can be added to the solution to help remove it.

3. Thrips

The disease and insect of thrips do great harm to the rose. As soon as it appears, the leaves of the rose will slowly atrophy and become deformed, and the growth rate of the rose will be affected after a long time. Thrips begin to breed most of the time in spring and flood the rose flowers in summer and autumn.

In spring, we can spray some imidacloprid every half a month in the evening to prevent it. If it is found that the leaves are still twisted and shrunk in summer and autumn, it will take a long time to spray imidacloprid to eliminate it.

The rose flower looks good, but you still have to be patient to help it eliminate the disease, so as to bring the fragrance to everyone. If there is a better method of deworming, leave a message and share it with Huahua.
