Do orchids give birth to bugs? What should I do if there are insects in the soil of the orchid?

Orchids can give birth to insects, but insect diseases are easy to prevent, and mycosis is difficult to treat, orchids.

If scale insects are found.

and other pests, dimethoate can be used.

Or the enemy is killed according to the instructions, it is best to mix it, 2-4 times a year. General mycosis can also be treated such as black spots, can be killed, methyl debuzin, white fungus and other fungicides according to the instructions, the growth period of 15-20 days regular cross** and preventive spraying, if found bayaline soft rot (rotten coccosis) it is a terminal disease in the orchid can not **, once found to remove in time. Therefore, when buying bluegrass, we must pay attention to the purchase of low-quality diseased grass, which will affect other precious bluegrass.

Sterilization treatment should be carried out (exposure to the sun is sufficient) to prevent the occurrence of diseases. Orchids are most susceptible to white silk disease in rainy and high temperature seasons, and can be used with Tobuzin 800 times liquid or Bordeaux solution.

Spray prophylaxis. If the disease is severe, Tobuzin can be released 500-750 times, and sprayed every 7-10 days. Among the insect pests, scale insects occur the most, and this insect is attached to the base of the leaf, if scale insects are found, they should be removed in time.

To avoid scale insect infestation, it is available from April"1059"2000 times liquid control.

In order to inhibit the occurrence of orchid diseases, in addition to the usual dry and humid potting soil should be properly controlled, mud pots should be used as much as possible in the selection of pots, and less glazed pots should be used. Especially for the newly dug orchids with poor growth, they must be planted in mud pots.

Seed. Doing so makes the potting soil dry out easily, which can promote the growth of orchids and reduce the incidence of disease.

There are a bunch of small black spots on the leaves of orchids, and you can prevent this problem by paying more attention to it.

In fact, it is very simple, go to the flower shop to see and buy a bag of plants, a pack of watering cans to spray plant leaves, orchids are very good to raise, like scattered light, and can be dried and watered thoroughly in a bright place indoors.

Orchids are at their peak in spring and autumn, with spring buds beginning in March, and then in autumn from October to December, and dormant in summer and winter. In order to germinate more new shoots, it is necessary to maintain the right temperature, sufficient light conditions, and a reasonable combination of fertilizer and water.

1. Orchids germinate and grow in spring and autumn.

Orchids are very popular potted plants, and orchids enter the germination period from March in spring, and the growth period begins. In the summer, it is dormant and in October and December, when new shoots sprout again, known as autumn buds.

2. Measures to promote germination and growth.

1. It can be watered every two or three days in spring and autumn, and once a week when it is dormant. Every time you water, prevent water from splashing on the leaves to avoid black spots. The best watering quality is rain and snow water, and you can also pour fermented rice water.

Therefore, shade should be done appropriately in spring, summer and autumn, for example, before 9 a.m. to 6 p.m., and the curtains should be opened in the morning and after 6 p.m. to allow them to receive scattered sunlight. In winter, you can move indoors to a place where you can diffuse light and avoid direct sunlight.

3. When germinating in the spring bulb season, potassium dihydrogen phosphate foliar fertilizer can be sprayed first to promote its growth. When entering the peak growth period, thin liquid fertilizer can be applied every half month. This is conducive to the full absorption of nutrients by the root system, to achieve flower bud differentiation, and to facilitate the purpose of flowering.

1. Shellworms. Scale insects are the most common pests on orchids. Wild orchids in nature are also often infested by scale insects.

There are many kinds of scale insects, and the most serious ones are generally the shield scales. Striped mealybug, blue scale, brown round scale, red scale, black-spotted clam.

In addition, there are a variety of scale insects that can harm orchids, and scale insects mostly occur when the orchid is too wet and not ventilated. It ventilates and reduces moisture. And the following drugs are sprayed to kill, but the scale shell after its death is still attached to the orchid plant, and it must be manually removed if necessary.

25% quithion emulsion, add water 500 times.

20% dimethoate EC, add 500-800 times of water; 40% dimethoate EC.

then add 1oo0---500 times of water; For 60% dimethoate soluble powder, add 1oo0---2000 times of water.

Cotton oil soap with a 1:50 solution, spray 2-3 times continuously.

50% trichlorfon with 250 times solution.

50% malathion, with 800-1000 times the solution.

50% phosphine, with 800-1000 times the solution.

50% 1605 emulsifiable concentrate, with 2000---3000 times of liquid; 50% emulsifiable concentrate of methyl 1605 is used with 1500-2000 times of liquid.

90% fluoroacetamide raw powder, with 1000-l600 times liquid.

25% imidothion emulsion, with 400 times the solution.

50% dibromophos emulsifiable concentrate, with 500-1000 times liquid.

In addition, it can also be washed with tobacco stalks or garlic mashed and soaked in water, which can also have a certain effect.

2. Mites. This type of pest is a mollusk, round, milky white egg, lays 1---2 eggs per day, hatches in 5 days, and develops into an adult worm in 1 week. Common species are: spider mites, mites. These pests can be killed with the following drugs:

Kaile San 35% powder, diluted 1000 times.

Mites must die wettable powder, diluted 1000 times.

Exterminate mites with 2000 times the liquid.

Dilution of acarpine 1000 times.

Kill carb, with 1000 times the liquid.

In addition, drugs such as acaricide, 1605, malathion and so on can also be applied.

3. Thrips. Thrips are often harmful to orchid leaves, sucking epidermal tissue, causing small white spots to appear on the leaf surface, in addition to harming orchids, it can also harm citrus and some plants of the Araceae family.

Thrips can be used for lindane. 1605?Dimethoate and other drug sprays.

4. Aphids. Aphids, which are harmful to crops and horticultural flowers, can also be harmful to orchids. Aphids are the most common pests, and there are many species, which often occur when the weather is dry. Common ones are: peach aphid, lily aphid, cotton aphid, black aphid.

Aphids can be sprayed with drugs such as Tep, 1605, Malathion, Lindane, Insect Phosphorus, Dimethoate, Rotenol, etc.

In addition, there are ants. Slugs. Snails and other small animals are harmed. It can be booby-trapped with bait and mixed with arsenic with bran. trichlorfon, etc., sprinkled in places where they are often active; It can also be in the wet. Where they hide, sprinkle quicklime or table salt.

1. Causes of long worms.

During the pickling period, if the environment is not suitable or the method is not appropriate, it is easy to cause various insect infestations. Once the disease occurs, it will affect the growth and beauty of the plant, so it needs to be sprayed to prevent and control. Of course, different pests and diseases can be sprayed with different drugs, and the corresponding drugs should be selected according to the specific pests.

2. Solutions to various pests and diseases.

1.Scale insects: Scale insects are the most common pests.

Once triggered, they affect the leaves and fruits, causing the leaves to turn yellow. If left untreated, the whole plant will slowly wither. Spray 255 phosphorus 1000 times solution as soon as possible.

2.Spider mites: Spider mites are small and difficult to spot.

It will suck up the sap from the leaves, causing the leaves to turn yellow, and in severe cases, they will fall off and wilt. When found, the diseased leaves should be removed in time. If a large area is damaged, spray 40% dimethoate EC 1500 times to kill.

3.Yellowing: This disease occurs mainly on leaves and causes them to turn yellow.

If left untreated, the leaves will fall off early. When the disease occurs, dichlorvos should be sprayed to eliminate it. About once a week, two or three times can be cured.

4.Anthracnose: This disease causes disease spots on the leaves of plants, which eventually cause the leaves to dry up and fall off.

When the disease occurs, it should be eliminated with 600-800 times of Guoguang Song Weiyintai wettable powder.

1. Pesticide prevention and control. When it is found that there are small insects crawling outside the flower pot, it is already serious at this time, and you can use pyrethroid pesticides, such as cypermethrin, cyhalothrin, etc., and you can also use avermectin, matrine, etc.

2. Change the planting material.
