原来以为是羞答答的玫瑰静悄悄的开，可惜是玫瑰生病了，我看到叶子后面有一层密密麻麻的橘红色小虫子，这是什么毛病，买什么药啊？谢谢咯！

照片有点看不清楚。 有可能是rust, google 一下rose rust 看看是不是。
楼主应该给玫瑰剪枝了，就算没rust ，冬天也应该给玫瑰剪枝了，且不留任何叶子，最后喷lime sulphur。

白丁問句：這個季節再剪還來得及麼？
春天都來了

谢谢大家的指教，我去了帮您死了，也看到rose gun,有好多症状，比如black spots啥啊，就是没有rose rust, 而另外一种什么什么gun, 其中标明了rust, 还有写了for rose and other plants, 买哪种好涅？

白同学，我也有同样的疑问涅，但是我家爷爷说这周三帮我剪枝条，我都不晓得咋办咯！

這個我大概知道，玫瑰冬天要剪的禿禿的
不然來年花就開不好
一定要捨得下狠手
你看看公園裡的玫瑰現在啥模樣？
照著剪就好了
就是不知道這個季節還行不，我覺得現在都春天了

谢谢指点，顺便说一下，我比你白！

之前的童鞋说8月剪枝嘛。但是因为我的玫瑰6月的时候，就病病了，所以当时就全剪光了。现在都长了叶子还有花骨朵了呢。

Rose rust is a VERY serious affliction that is capable of killing smaller roses quickly if left unchecked. Rust is a fungus that has bright reddish brown, sometimes even bright orange powdery looking spots that resemble warts. These appear in colonies underneath the leaves and on the wood. As the infection worsens, the color can appear on the upper surface of the leaves as well. As the spores age they turn to dark brown and then to black pustules and in the process, the leaves are killed and will wilt and then fall off. Rust is pretty easy to spot. Spores only remain viable below temperatures of 85 degrees F. These colonies grow and spread into each other and can eventually cover entire large areas of the plant. It is most likely to occur in the spring in areas when it is very wet for a period of time. In the USA it is most prevalent in the Pacific Coast regions, but can occur in other areas. In areas with hot summers and cold winters rust is not much of a problem. When you first see an outbreak of rust it is very important that you cut off the infected leaves and canes that have the rust present and carefully take them away from the area and dispose of them in the garbage. DO NOT put this into your compost pile. The spores overwinter on leaves that fall to the ground and not on the wood. Dead spots are left on the canes where rust has once been. These areas can be the entry point for other fungal infections, and so the canes should be cut off below where the damage is.
Treatment:
Prune before bud break in the spring to reduce the quantity of spores still present on old leaves and stems. Remove these prunings from the garden and destroy them. Sulpher and lime sulpher applied in early spring when the plants are still dormant seem to work well. Chemical control after leafing out is difficult, because the spray has to be directed upward to the underside of the leaves. But that said, the same fungicides as are used to treat blackspot do have a preventative effect. According to Peter Beales,"...if an attack is diagnosed at an advanced stage, oxycarboxin, a chemical available under several trade names, is quite effective. Some sources say that too much potassium in the fertilizer will favor the production of rust. Another reason to not overfertilize. For what it is worth Rosa multiflora rootstock has shown itself to be relatively immune to rust.
