As a common indoor potted plant, the efficacy of peony orchid is very strong, it is not only good-looking, but also not vulnerable to diseases and insect pests, but also has good value in edible. But in indoor farming, for some reasons, peony orchid will inevitably be infected with disease and be disturbed by insects. So, what should I do if the peony orchid grows worms? Here are five kinds of peony pest control, let's go and have a look!

First, peony hanging orchid long worm, spray with medicine

The breeding method of peony orchid is not difficult, only need to pay a little attention to water and fertilizer, and give it enough light, it can grow very well. But in the breeding process, because of the basin soil stagnant water, poor ventilation and other conditions, it will suffer diseases and insect pests. As for the peony hanging orchid worm how to do, in fact, it is very simple, indeed insect pests, and then aimed at spraying can be solved.

II. Disease and pest control of peony orchid

1. Aphids

Indoor potted plant is the most common pest, which also endangers the health of peony orchid. The insect mainly harms leaves and buds and absorbs a lot of juice, resulting in poor plant growth. Because aphids multiply, they are usually found densely packed, not only frightening, but also very disgusting.

Prevention and control methods: if the number of aphids is very small, you can take artificial aphid control, brush off the aphids with a brush and bury them in the basin soil; if there are many aphids, you need to spray related agents, such as 1000 times of omethoate or 1000 times of dichlorvos, sprayed once every 10 days and sprayed for 3 times in a row.

2. Scale insects

In addition to aphids, in the case of dense plants and poor ventilation, peony orchids are also vulnerable to scale insects. The insect will attach to the leaves and make the leaves lose their luster, resulting in the yellowing of peony orchid leaves, and in severe cases, the whole plant will die.

Control method: move the plant to a ventilated place, cut off the diseased leaves to reduce the source of insects; then spray 40% omethoate diluted into 1000 times solution or 50% malathion diluted into 1500 solution for control.

3. Red spider

In addition, the red spider is also one of the peony hanging orchid diseases and insect pests, although it is very rare, but once the occurrence of great harm. It is understood that the insect mainly harms the leaves of the plant, causing small yellow and white spots on the leaves of the peony orchid, then gradually turning red and extending to the whole leaf, even causing the leaves to curl, wither and fall off.

Control methods: after the discovery of red spiders, 1500-2000 times trichloropropanol EC can be sprayed every 7 days, 2-3 times, and the effect is good.

4. Root rot

When it comes to peony orchid diseases and insect pests, the most common is root rot, which is mainly caused by stagnant water in basin soil and poor ventilation. Symptoms: root rot, leaves withered and yellow, until death.

Prevention and treatment methods: when the above diseases are found, 50% carbendazim wettable powder can be sprayed 500 times, or it can be irrigated directly once a week; when the disease is serious, pull out the peony orchid, remove its rotten roots, and change the soil and basin to replant.

5. Leaf blight

Under the conditions of high ambient temperature, high humidity and poor ventilation, peony orchid will also suffer from leaf blight. Disease symptoms: peony hanging orchid leaves first turn yellow, and then become brown disease spots, and finally spread to the whole plant.

Prevention and treatment method: when the above symptoms are found, 70% of the concentration of Dysen zinc is diluted into 600 times solution to spray for prevention and treatment, once every 15-20 days, 2-3 this can be effective.

Generally speaking, in the process of cultivating peony orchids, as long as we put it in a ventilated place and be careful not to pour too much water, it will not suffer from diseases and insect pests.

In my spare time, carefully take care of the flowers and plants full of infinite vitality, the process of harvest is always accompanied by the optimistic spirit of self-entertainment, dull, dry and hot swept away, leaving only refreshing and fragrant.

Spend into the bedroom efficacy of multi-efficacy one: filter air in the summer room air conditioning utilization rate is very high, doors and windows are closed, air circulation will be bad. Therefore, it is appropriate to raise some flowers that can filter the air in the bedroom. Most flowers carry out photosynthesis during the day, absorb carbon dioxide, release oxygen, breathe at night, absorb oxygen and release carbon dioxide, while cactus, tile pine and other types are just the opposite. Keeping these air-filtering flowers in the same room with other flowers can effectively balance the content of indoor oxygen and carbon dioxide and keep the indoor air fresh. Efficacy 2: detoxification orchid, aloe, tiger tail orchid can absorb a large number of indoor formaldehyde and other pollutants, eliminate and prevent indoor air pollution. Especially hanging orchid, put a pot in the room, within 24 hours, its leaves will "eat" harmful gases such as carbon monoxide in the indoor air, and its effect is even better than the air filter. Milan, orchids, cloves, cactus, Tianzhu and so on can effectively purify the air. Camellia can resist the damage of harmful substances such as sulfur dioxide, and crape myrtle has strong resistance to indoor sulfur dioxide, hydrogen chloride, chlorine, hydrogen fluoride and other toxic gases. Plum has the ability to monitor the pollution of sulfur dioxide, hydrogen fluoride, hydrogen sulfide, ethylene, benzene and aldehydes in the environment. Once sulfide appears in the environment, markings will appear on its leaves, or even withered and yellow. Because flowers have these functions, the room that has just been decorated is more suitable for raising these flowers. It should be pointed out that there is a limit to these functions of plants, so it is necessary to open windows frequently to make air convection. Efficacy 3: kill germs such as rose, sweet-scented osmanthus, violet, jasmine, lemon, rose, carnation, lily of the valley, crape myrtle and other aromatic flowers with significant bactericidal effect. Crape myrtle, jasmine, lemon and other plants can kill protobacteria such as diphtheria and dysentery in 5 minutes. The fragrance of rose, carnation, lily of the valley, violet, rose and sweet-scented osmanthus has obvious inhibitory effect on the growth and culture of Mycobacterium tuberculosis, pneumococci and staphylococci. It should be noted that although flowers have a lot of benefits, do not treat the bedroom as a "greenhouse". Most flowers release carbon dioxide and absorb oxygen at night, and most of the rooms are closed at night. coupled with the carbon dioxide exhaled by the soil, the human body and pets in the flowerpot, it will increase the concentration of carbon dioxide, cause hypoxia and affect health. Experience of spending the summer on flowers: uncle Xie, 61, retired and raised flowers for 40 years. Tips: pay attention to the location.

The leaf surface can also be sprayed with water properly. For acid-loving flowers, it is best to pour 0.2% to 0.3% of black alum to prevent chlorosis caused by iron deficiency. Some fleshy root flowers, such as orchids, can not stand the sun exposure, can be relatively dry at noon when spraying some water on the leaves moderately. Some of the more drought-tolerant flowers, such as cactus and crassulaceae, should drink less water, and their roots are prone to rot if there is more water. Veteran florist: Ms. Zhang, 37, a civil servant, has cultivated flowers for 14 years. Tips: pay attention to moisturizing and sunscreen. The key to growing flowers on the balcony of the building lies in the humidity, that is, moisturizing and sunscreen.

In addition, after drying the brewed tea, sprinkling it on the surface of the potted soil can also prevent flowers from growing insects. Summer flowers skillfully maintain jasmine summer is the full bloom of jasmine, sufficient water and fertilizer is conducive to flowers and leaves to flourish. Spraying foliar surface with clear water on a sunny day can obviously stimulate flowering. Orchid summer is the peak growing season of orchids, which should ensure water and nutrients. When the disease occurs, topiramate can be sprayed every 10 days. Cuckoo summer cuckoo growth is slow, in a semi-dormant state, avoid hot sun exposure and excessive fertilization, should be shaded. Water once or twice a day, and spray water to the leaf surface and the ground to moisturize and cool down. Peony avoid heat and humidity, summer plants should be placed in a ventilated and cool place, do not need too much watering, keep the basin soil moist, so as to avoid rotting roots. Rose likes fertilizer and water, so it is necessary to ensure an adequate supply of fertilizer and water, apply rotten bean cake water every half a month, and stop fertilization in mid-July. Black spot and powdery mildew are easy to occur in summer. the former is sprayed with Bordeaux solution and the latter with carbendazim every half a month. Milan likes light and heat, and Milan grows vigorously in summer. Thin alum fertilizer should be applied every 10 days before and after flowering, and water should be sprayed to the leaves frequently. The flower world is exuberant (picture)
