What pests and diseases are orchids easy to attract? How to prevent pests and diseases in orchids?

The most important insect pest of bluegrass is scale insects, some bluegrass has scale insect pests, all leaves are covered with dense scale insects, it looks very scary, scale insects are not effective in insecticides, generally only use bamboo or blades to scrape off the insects on the leaves, or soak them in edible vinegar with small cotton balls, and then gently rub them on the leaves, which can kill the scale insects on the leaves.

In general, it is easy to provoke some insects such as ordinary heartworms, and it is also relatively common to be like some honey worms.

Spring and autumn days are prone to beetles, red spider classes, powdery mildew, etc., for different lesions, we must find early **, so as to avoid cross-infection, resulting in the death of the entire flower and plant potted plants, and finally it is too late to regret it. If there is powdery mildew or spider mites in orchids, the first thing to do is to use insecticides to sterilize and disinfect them to kill the young eggs of the pest and curb the spread of the pathogen at the source.

It is a pest and disease that is particularly easy to attract aphids, so it is important to take care to prevent tooth insects when planting bluegrass.

Orchid grass is easy to attract mealworms and leaf roller worms.

In this case, you need to spray a little carbendazim.

Hello, bluegrass has a strong vitality and is not liked by insects, but some beetles will bite the young leaves of bluegrass when there is no food.

This orchid grass is easy to attract that little flying insect, so you usually have to spray some potions on the blue grass to prevent this little flying insect.

What pests and diseases are susceptible to? Orchid grass is less susceptible to pests and diseases because its flowers are not very leafy and not very tasty, so insects do not like to patronize it.

Bluegrass is easy to attract those pests, bluegrass, easy to suffer from those pests, so go to the animal husbandry to buy some pesticides and spray him.

Hey, hello, it's not easy to find a tobacco, it's better to find tobacco in the city.

As a domestic potted plant, it is very common for orchids to have diseases, although they are not normal. Friends who have raised orchids know that orchids are most prone to various diseases, especially in spring and summer. We also try various drugs to prevent and treat, but the drug is always after the disease, even if the disease is controlled, the seedlings will be damaged to varying degrees.

So, is there any way to raise orchids to stifle diseases before they break out? There must be a way, but it is also something that few Lan You have said. Because most people only look around for a cure when the orchid is already sick.

In his previous experience in raising orchids, he has also tried various methods to treat diseased orchids, and some of them have achieved good results.

Boss Cai asked again: Then since he is a miracle doctor, how can he talk such nonsense?

This is true for humans, and the same is true for plants. When I was domesticating the orchids in the lower mountains, I also followed them all the way and recorded that some orchids had never been diseased from the time they came down the mountain until they burst into pots and seedlings. Orchids grown under the same environment will have disease records for others.

What is it that makes these orchids so resistant to disease? This is the focus of this article, and it is also the "secret technique" of raising orchids that I have been pursuing. Of course, it's only a preliminary brow, and I hope to share it with Lan friends.

Raising orchids is very interesting, if you carefully observe (follow for a long time) a tree or a batch of orchids, you will find such an interesting phenomenon - the strong are always strong. The strength of an orchid from planting, the first sprout, and the first stubble will directly affect its chance of getting diseases in the later stage.

The stronger the seedling, the more robust the new seedlings usually sprout, and the less likely it is to get disease. This comparison is made in a unified management environment, so it is certain that strong orchid seedlings have their own disease resistance. In the same management environment, other orchids have diseases, and it is impossible for these robust orchid seedlings not to be attacked by germs, but many of them win overwhelmingly in the fight against germs.

As a result, even occasional anomalies recover quickly.

Raising orchids is prone to pests and diseases, and 2 minutes will tell you how to prevent them.

Pay attention to the necessary preventive medication, and administer the medicine before or at the beginning of the disease. Prophylactic medication can be given regularly once every six months from May to October, when the disease is prone to occur. When using the drug, it is necessary to pay attention to the alternating use of several drugs, and the concentration is controlled at about 800 1,000 times.

It is important not to use a drug at high concentrations for a long time to make the bacteria resistant.

Keep the soil clean and don't add nutrients that haven't been fermented. After watering, ventilate more so that the excess water evaporates quickly.

1. Peculiar vegetables. Peculiar vegetables have their own peculiar smell, and their smell can play a role in insecticide. 2. Tea seed cake.

It is the residue left over from the tea, because it contains a lot of saponins and glycosides, which have a good contact killing effect on pests after soaking in water. How to use: Soak the tea residue in water overnight, pour the orchid pot with courage, or spray the orchid plant, which has a good control effect on aphids and red spiders.

3. Cigarette butts. Tobacco leaves contain nicotine, which has a killing effect on pests. Wait a minute.

To prevent pests and diseases, we must first know the living habits of pests, they generally have to find a host to overwinter in winter, most of the time they live in dead branches and leaves, as well as in the weeds on the ground in the orchid garden. Therefore, it is necessary to tidy up the orchid garden in early winter every year, and remove some dead branches and leaves and weeds on the ground, so as not to leave a chance for pests to overwinter.

Around the Qingming Festival in the following year, insecticides were sprayed in the orchid garden. Various pests have different sensitivities to drugs, so the drugs should be diversified and cross-used. Try to strangle the first generation of pests after overwintering, otherwise the pests are very repious (e.g. aphids and scale insects).

Raising orchids is prone to pests and diseases, and 2 minutes will tell you how to prevent them.

Strictly implement the disinfection measures of seedlings and planting materials, and apply pesticides in a timely manner.

Plant-specific insect repellent should be used and evenly sprayed on the leaves of the plant, and watering should not be done during the medication, otherwise there will be no effect.

Scale insects often occur when orchids are too wet and not ventilated. It can be sprayed with 50% trichlorfon 250 times, 5% malathion 1000 times, and 50% octathion 1000 times. Thrips, diluted and sprayed with lindane, 1605, dimethoate, etc.

Aphids, diluted and sprayed with lindane and dimethoate chloride. Black rot, sprayed with methyl tobuzin, stone sulfur mixture, carbendazim and other agents. Mycosis disinfects the soil and burns the diseased plants.

Bacterial soft rot can be sprayed with Bordeaux liquid, methyl polythion, etc. Leaf spot disease can be sprayed with boric acid solution, dichlorbis, dithion, etc. Orchid.

The main pests and diseases of orchids are:

1) White silk disease: It mostly occurs in the rainy season. Attention should be paid to ventilation and light transmission, good drainage of the potting soil to prevent it, after the onset of the disease, the infected potting soil can be removed, sprinkled with pentachloronitrobenzene powder or lime.

2) Anthrax: It occurs all year round, and it is even more rampant in the hot and rainy season. In addition to improving environmental conditions, the onset of the disease can be treated with 50% methyl tobuzine wettable powder 800 1500 times liquid spray, once every 7 10 days, and then supplemented with l% equivalent Bordeaux liquid, once every half month.

3) Scale insects: in the case of high temperature and humidity and poor air flow, the fastest reproduction. Use conventional methods to prevent and control.

Would love to help! But can you be specific? Orchids are widespread! Breed name?

Due to the fleshy quality of the root, it is easy to reduce the resistance to diseases and insects due to root rot and the gradual loss of conduction function. Also because the leaf sheath of Yilan is tightly wrapped around the leaf base, and the orchid leaves cover each other, the agent is not easy to involve, which brings difficulties to the prevention and control. Therefore, it is necessary to do a good job in the following four aspects:

Strict disinfection: seedlings, substrates, pots, and sites should be disinfected with 600 800 times liquid sterilization and insecticides.

Attention should be paid to ventilation and light transmission, less nitrogen, more phosphorus and potassium to improve the stress resistance of the plant.

Aspirin (acetylsalicylic acid), a 1500 times liquid medical antipyretic analgesic, is sprayed once a quarter to induce the production of resistant eggs in the plant to prevent, kill and inhibit the invasion of pathogens.

Root application for pesticide control. The residual effect period of general pesticides is mostly 7 to 10 days. For this purpose, the pesticide should be applied 3 to 4 times a month.

Pesticide varieties should be alternated, medium concentrations should be selected, and spraying should be comprehensive and thoughtful. The leaf surface, leaf back, pot surface, under the orchid frame and channel, and the environment should be fully sprayed.

Maintain orchids, the most common pests and diseases, and prepare these two things for it, you can control it well.

Insect pest control of orchid flower bonsai: due to poor ventilation and high humidity, orchid flowers are prone to black spot and mold damage. Black spot disease often harms new shoots, and in severe cases, the whole plant dies.

In addition to strengthening ventilation and controlling air humidity, 600 times of 65% zeb wettable powder can be sprayed. Mycosis causes rhizome rot, which can be controlled by spraying 500 times of pentachloronitrobenzene powder. In the process of old cultivation of hermitage, if scale insects damage the leaves, they can be sprayed with 1000 times of 40% dimethoate emulsifiable concentrate.
