More and more people around us are raising flowers and flowers at home, which can not only beautify the environment, but also cultivate self-cultivation, cultivate sentiments, and enrich our amateur life. However, in the process of raising flowers, you will find diseases and insect pests that are not commensurate with the beauty of flowers, such as raising flowers at home, sometimes breeding a lot of small black flying around at home, affecting the mood of raising flowers.
Moreover, raising flowers indoors is also prone to some leaf spot disease, leaf blight, powdery mildew and other unknown diseases and insect pests, and after seeing it, it is helpless, and it does not know and does not know how to treat it. Therefore, if you like to raise flowers, it is also very necessary to master certain insect prevention and prevention of germ infection skills. Today, we introduce several common pests and diseases of flower cultivation and bacterial infections, discover, understand, and treat them in order to get better prevention and treatment effects. Raising flowers will be a great one.
First, leaf spot disease
Leaf spot disease is often seen when raising flowers indoors, and its main manifestation is that the leaves are full of brown spots, and these brown spots will gradually spread around, making the leaves of the plant mottled and beautiful. Slowly the whole plant will develop this leaf spot disease, because they will spread as if they will multiply.
This is caused by leaf bacterial infection, such as raising moon season or other foliage plants at home, poor ventilation, spraying them indoors caused by water in the leaf area caused by the infection of germs, this is a bacterial infection, so use bactericidal drugs.
Home flowers, usually prepare carbendazim or manganese zinc, sprayed twice a month can be effectively cured, and in the home ventilation of the environment or rainy weather, do not give plant spray moisturizing, to prevent the breeding of leaf spot disease, usually give plant spray moisturizing, it is best to put in a well-ventilated place, let their leaf surface moisture dry quickly, to prevent the occurrence of leaf spot disease.
Second, powdery mildew
Friends who raise the moon season on the indoor balcony are certainly not uncommon for powdery mildew, which is most likely to occur in the peak season of plant growth. There is a layer of white flour on the leaf surface of powdery mildew, which cannot be wiped clean, and generally begins to grow at the bottom of the leaf, gradually spreads to other leaves, and finally spreads to the buds, causing the entire plant to completely wither.
Therefore, if you find this powdery mildew, you must not hesitate to treat it quickly, the drug that treats powdery mildew, which is more effective, can use double mold, or you can go to the Internet to search for drugs to treat powdery mildew. Spray once a month, and add ventilation to the plant, you can effectively prevent, if not prevented in time, the harm to the plant is also relatively large.
Third, smoky mildew
Tobacco mold disease is often seen when raising succulents, that is, there is a layer of black and dark things on the leaves of the plant, just like bituminous coal, and it is more sticky to touch with your hands, which is mainly caused by pests and diseases. For example, if an aphid or aphid shell insect is born, they will secrete some slimy, sweet and nourishing things to fall on the leaves, and over time, it will cause bacterial infection, which will cause smoke mold disease.
If there is such a situation, it is necessary to kill the aphids and aphid shell insects in time, if there is such coal ash on the leaves, it is necessary to wipe it with a damp cloth dipped in alcohol in time, as long as the pests and diseases are controlled, this bituminous coal disease will naturally be cured, which is also a bacterial infection problem caused by diseases and insect pests.
Fourth, whitefly
Whitefly will often be seen when raising flowers outdoors, on the back of the leaves of the plant, touched with your hands, just like some small white bugs flying around, the number is very large, and the flight speed is relatively fast, spraying is not easy to kill, because they have wings, it is not easy to spray them, so when spraying, you must think of more ways to do it.
In the outdoor flower, you can spray some drugs to treat whiteflies, such as pyridoline, Avidin worm rice, but when spraying, it is best to have dew in the morning, their wings are stained with water droplets and fly slowly, at this time to spray, the effect will be obvious. Other times, if you don't spray them on the body, it won't have any effect. You can also spray the whole plant before spraying, spray it with water, after spraying, the worms will fall on it, and then spray it after half an hour, at this time they fly slower, and the water droplets can also effectively kill this whitefly.
Fifth, aphids
Aphids are more common diseases and insect pests, if the friends of the moon season must be particularly familiar with aphids, every spring will be densely filled with a lot of aphids, to spray in time, if found one or two can be crushed by hand, if there are more, the drug is very necessary, directly to the outdoors, you can use avidinopurine, imidacloprid, you can also use other drugs to treat aphids.
Because indoor flowering is best to choose low-toxicity flower plants, spraying twice a week can be effectively removed, if you ignore it, the whole plant will soon be full of. They reproduce very quickly and specialize in nibbling on young shoots and leaves. This results in the loss of nutrients in young leaves, and the occurrence of yellow leaves, flower buds falling, and leaf ejection.
Sixth, the red spider
Friends who raise the moon at home must have a special headache for red spiders, if the leaves of the plant appear mottled, dotted with stars, like transparent leaves, or there are spider webs on the plant, this is the red spider, which is a very difficult to remove diseases and insect pests. Because they are more resistant to drugs, conventional drug spraying once or twice is not very effective, can be sprayed with several drugs in turn, the more common avidinopurine, or imidacloprid, golden branch, ethyprazole and so on.
When killing insects, it is best to spray the plant with water, because the red spider is more afraid of water, and after watering they will climb on the plant, so that they can spray the drug to completely kill them. Therefore, if this red spider is seen, it should be treated in time, otherwise it will flood everywhere, increasing the difficulty of killing insects.
Seventh, leaf rot
Leaf rot is also more common in the family, if the leaves of the plant are like black and rotten when raising flowers, some are at the bottom of the plant, some are at the top of the rotten leaves, the leaves are black or black spots appear, etc., and gradually spread to the entire plant, which is leaf rot.
Leaf rot is due to poor indoor ventilation, and the humidity of the potting soil is too large caused, in the family balcony flower ventilation is not too good, if too much watering will cause this situation, this is a root system problem, and manifested in the leaves. If it is found to cut off the diseased leaf, and put it in a well-ventilated place to dry the pot soil, pour some sterilized manganese zinc or carbendazim, etc., gradually improve the maintenance of the situation, so that the root system slowly recovers.
There are too many rotten leaves, you must take off the pot to repair the roots, and then re-pot. Therefore, it is still very necessary to raise some common drugs and sterilization drugs at home. For example, the common bactericidal drugs carbendazim, manganese zinc, methyl tolbuzin, bacillus, etc., the common insecticidal drugs avipyridine, imidacloprid, etc., can be prepared to prevent insects from being invisible, and it is convenient and fast when killing insects.
