Small diseases and insects do great harm to the rose. I love to catch it.
Red spider this kind of disease and insect pest, hehe, I can only say that its flooding momentum is as fierce as a surging river. Some flower friends once complained that it was not long before a pot of rose was bought, and the money to buy medicine to cure the red spider was several times that of the original rose. This is not an exaggeration at all, because the disease of the red spider is also jokingly called "the invincible Xiaoqiang".
Red spiders usually start their activities in spring and then breed in large numbers in summer and autumn. In areas where temperatures are mild all the year round, red spiders can be active all the year round. Red spider is actually a kind of worm, the color is red. But by the time you find the leaves full of these red bugs, it's already too late.
So prevention is the first step. Red spiders like the hot and dry environment, high temperature in summer and dry in autumn, so these two seasons are the most active seasons for red spiders. It is understood that rose planted in a closed balcony, indoor or greenhouse is more likely to catch the disease, obviously, lack of ventilation is a major factor leading to the disease.
What are the initial symptoms of this disease? At first, there will be some white dots on the leaves, then the leaves will turn yellow, and then the leaves will fall off like sun-drying. This is the pre-incubation period of its young eggs. Some people will say, I didn't know it was red spider disease. No matter what it is, if you find something unusual in the leaves, you should cut it off immediately.
Cutting off diseased leaves is to eliminate the source of diseases and pests, reduce the harm of reproduction and infection of other branches and leaves, and increase the ventilation and permeability of branches and leaves to effectively reduce the speed of germ reproduction. After cutting off the diseased leaves, spray with 20% diclofenac EC 1000ml 1500 times, 100ml acaric EC 4000ml 6000 times, 73% acarate EC 15003000 times.
The frequency of medication can be 5-7 days, at least 3 times continuously, it is better to use a variety of drugs alternately, in case the therapeutic effect of a certain drug is limited. If you don't have any medicine on hand for the time being, a more violent way is to flush it with water. Putting the plant upside down and then washing the leaves with showers or water pipes can also wash away some of the bugs.
