Rookie breeding pest chapter: thrips or fat pest? Foolishly confused, the rose died
Rose, to many flower friends, should be an old acquaintance, now the weather is sunny, then heavy rain, this rose is a famous medicine pot, such a toss, all kinds of diseases immediately ran out. Yesterday there was a rose flower friend message, but also attached a picture, we look at this leaf, the first feeling is what causes the leaf roll?
At first glance, is it caused by fat? The new leaves are slightly curled, reddish brown, and will gradually wither. Let's take a look at the pictures of fat harm. The first feeling of the two pictures is still relatively similar. When I first saw it, I also thought it should be fat damage, and then continued to chat deeply with flower friends. I made a mistake. It turned out to be thrips.
Thrips, also a common pest of roses, usually live in young leaves, causing their top to die, resulting in no growth. If it feeds on the back of the leaf and excretes brown material, it will make the back of the leaf deformed, and the sides of the midvein will also appear gray or taupe stripes, deformed and bent, which can still be seen from the picture.
How to treat? It can be treated by spraying medicaments, and the effective ingredients containing pyranthion, acetamiprid, thiamethoxam, etc. can be selected. But use it according to the instructions. This flower friend has thickened the medicine, so the curly leaves in the first picture appear, which looks like fat wounds.
How to fertilize roses in summer? The first is the choice of fertilizer. Summer weather is hot, rose absorption capacity is not so good, if the choice of chemical fertilizer, roots can not absorb it will easily adhere to the root surface, resulting in rotten roots. Therefore, it is best to choose a good liquid fertilizer in summer.
Flowers know rose dedicated organic nutrient solution is pure plant fermentation, the effect and home rotten branches are the same, rose absorption is better, long-term use can improve the rose disease resistance, pest prevention or treatment, really sick and then late, sometimes also cure it.
