It should be said that the most popular insect attracting flower is the rose. The rose blooms for a long time and has a strong fragrance. At this time, there will be some small flying insects or diseases. Today, Huahua will give you some tips to deal with the common diseases of rose flower and make it get rid of the title of "medicine jar" from now on

1. Black rot

Black rot is a common disease of rose flowers, and many rose flowers die because of this disease. The phenomenon of black rot is that some small dark brown spots appear on the leaves first. 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. In spring and summer, it is best to spray mancozeb every half a month, so as to reduce the probability of black rot. If it already appears, don't panic. First remove all the leaves with black rot, and then spray them with disinfectant solutions such as carbendazim. In this way, there will be no problem for a week

2. 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 white powder. In serious cases, the whole leaves will be pasted. In this way, how can rose flowers without photosynthesis grow vigorously

When powdery mildew first appeared on the leaves, it usually concentrated on the edge and back, and then slowly spread to the whole leaves, sometimes even the petals. Powdery mildew usually occurs in spring and autumn. When it occurs, we can spray it with the same disinfection solvent as the treatment of black rot. however, because powdery mildew is adhered to the leaves, we can add some viscous liquids such as detergent to the solution to help remove it

3. Thrips

Thrips, a pest, do great harm to roses. As soon as it appears, the leaves of roses will slowly shrink and become deformed. After a long time, the growth rate of roses will also be affected. Thrips breed most of the time from spring. In summer and autumn, they will be flooded with roses

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

Rose flowers look good, but we should patiently help them eliminate diseases, so as to bring fragrance to everyone. If there are better insect repellent methods, leave a message and share with Huahua
