How to control spider mites in home flowers?

Soak the tobacco in water and pour the soil.

Prevention and control methods: drug control can generally spray a mixture of 10% phenylpyridoxin (1000 times the solution) + emamectin benzoate emulsifiable concentrate (3000 times the solution), and biological control can generally use the protection of its natural enemies (such as small flower bugs, bundle tube food mite ladybug, phytosui, large lacewing) to control the number of red spiders. Other effective drugs to control spider mites:

Ickami, Jin Manzhi, Ke Mites, Pyrida Mite, etc.

1. How to prevent and control spider mites.

1. Protect the natural enemies of red spiders.

There are many types and numbers of natural enemies of red spiders, such as heterochromatic ladybugs, small flower bugs, bundle tube mite ladybugs, deep-spotted mite ladybugs, plant mites, large lacewings, small lacewings, etc., and protecting them can play a positive role in controlling the number of red spiders.

2. Strengthen management.

Spider mites are a pest that likes to move in high temperatures, and its development cycle, reproduction rate is also related to temperature, usually when the weather is relatively dry, hot will break out in large numbers of red spiders, so we must strengthen the management of the field in the high temperature and dry season.

3. Drug prevention and treatment.

Spray with a mixture of 10% phenylpyridoxin (1000 times liquid) + emamectin benzoate emulsifiable concentrate (3000 times liquid), and good control effects can generally be achieved after application.

Red spiders are mites and need to be treated with the drug Red Kill**!

Every time the flowers change season, they are all "red spiders", in fact, it only takes 1 trick to completely eliminate insect pests.

Spider mites are one of the common pests of potted flowers, you can dig a circle of trenches on the surface of the soil layer, put a certain proportion of systemic insecticides according to the size of the pots, and bury them with soil. Drugs include carbofuran, aldicarb and so on. Just water it to ensure that no more flower pests grow in a year.

The insect is small, red in color, and not easily visible to the naked eye. Hi sucks the juice on the back of the leaves. After the killing, the leaves turn yellow, and many small white spots appear, which soon wither and fall off.

It often breeds in high temperature and low humidity environments. Commonly used (1) 40% dimethoate emulsion 1000 times liquid spraying; (2) 80% dichlorvos 1000-1500 times liquid spraying.

When using pesticides, it should be noted that (1) some plants are allergic to pesticides; (2) Do not use pesticides too strongly.

Flowers give birth to red spiders, which are used to expel and kill red spiders with things that are common in the home.

1.Laundry detergent prevention and control method, laundry detergent is alkaline, you can add an appropriate amount of water, prepare a solution of 1:500 to spray the damaged plants, red spider in the alkaline action, will slowly die.

2.Chili pepper control, the appropriate amount of top spicy chili pepper, mashed, add water to form a chili pepper solution spraying, red spider has never eaten chili pepper, it will be spicy.

3.Tobacco, tobacco has an insecticidal effect, preferably dry tobacco, it is spicy enough, and spider mites are also afraid of it.

4.Spicy knotweed, neem bark Spicy knotweed, neem bark, these two have been insecticidal since ancient times, many pests are afraid of it, this little red spider is of course not a problem, and others have lime water, sprinkle ground ash, etc., can be a good way to prevent the harm of red spiders to flowers.

It can be controlled with imidacloprid and pyrethroids, and the effect is better.

Red spider, also known as cotton red spider, commonly known as big spider, big dragon, sand dragon, etc., scientific name leaf mites, the species of our country are mainly cinnabar leaf mites, belonging to arachnids, ticks, leaf mites. It is widely distributed and has a miscellaneous diet, which can harm more than 110 kinds of plants.

1) This insect is very small, less than 1 mm, round or oval, orange or reddish-brown, because of the small size is not easy to find, once it is found to be a pest, often the flower damage is relatively heavy. This insect pest method is to pierce the mouthparts into the leaves and suck the sap, so that the chlorophyll is destroyed, and the leaves appear gray and yellow spots or patches, and the leaves are orange, fall off, and even fall light.

2) Commonly used pesticides are cartes, dicofol, etc. In 400 ml of water, 4 drops of mites or quick killing or flower insects can be dropped into 4 drops (equivalent to 2000 times the liquid medicine), shake well after adding the medicine, and then spray, spraying requirements evenly, especially pay attention to spraying the back of the leaves. When spraying, it is best to move potted flowers outdoors, such drugs are toxic and should be used with caution.

According to the species and performance of red spiders, the critical period of pesticide application should be mastered, the early damage should be completely eliminated, and the recurrence of rampant occurrence in the later stage should be controlled. In early spring or winter, spray 3 to 5 Baumé of stone sulfur mixture on the plants and add laundry detergent until the agent is added to enhance the spreadability. It can kill overwintering eggs or adult mites and reduce the base of the insect population.

From late April to early May, when the overwintering eggs hatch at their peak, apply or dry the rhizosphere with 5 to 10 times of 40% dimethoate EC and 30 times of 18% hypertonic dimethoate EC. In the infested period of red spiders, potted flowers, bonsaides, and roots are treated with aldicarb, phosphine and other granules, and the dosage depends on the size of the plant. After burial, it is necessary to pour enough water to improve the efficacy of the medicine.

Or directly pour systemic agents such as dimethoate emulsifiable concentrate. But stay away from water sources to avoid pollution. During the large occurrence period, you can spray 500 to 600 times of 20% dicofol EC, 2000 times of 20% dicofenol EC, 1500 times of 5% Nisolan EC, 1500 times of 50% monocrotophos EC, 1500 times of 40% hydrothion EC, 1500 times of 40% dimethoate EC, 3000 times of 10% Uranus EC, etc., which can greatly reduce the density of insect population.

In order to avoid the development of pests to develop resistance, drugs should be applied alternately or in combination.

Spider mites are a pest that harms crops, mainly attacking plants such as vegetables, flowers, etc., causing plants to weaken, leaves to yellow, and even death. In order to control spider mites, the following measures need to be taken:1

Maintain ecological balance: protect natural enemies such as mites, spiders, birds, etc., and control the population of spider mites. 2.

Improve environmental hygiene: Keep indoors, greenhouses and fields clean and hygienic to reduce the breeding and spread of spider mites. 3.

Adjust the ambient temperature: The suitable temperature for red spider spiders is 25-30 degrees Celsius, and the reproduction and growth of red spiders can be prevented by cooling or humidifying. 4.

Use of chemicals: In the case of severe infection, pesticides can be used, but they should be used in a precise way and in sufficient dosage to avoid harm to the human body and the environment.

It can be controlled with pesticides.

Plants with spider mites are sprayed with chemical pesticides separately to ensure that the source of the insect is eliminated and the transmission between them and other plants is interrupted. The effective agents are: butaflufenoxilate, bifenazide, ethoxazole, thiobenone, spirodifenolate, avermectin, gramamine and other alternate mu such as use.

99% mineral oil 200 times plus avermectin 2000 times, or 5% thiobenone emulsifiable concentrate 1500 times liquid spray, or 43% bifenazide ester suspension 2000 times; 7 days of prevention and treatment, 2 3 times of continuous prevention, a variety of agents alternate use of better effect.

Whenever possible, acaricides of mineral origin, such as mineral oil, are preferred. Mineral oil is relatively susceptible to pesticide damage, so caution should be exercised in high temperature, drought, weak tree, flowering period, physiological fruit drop period, veraison period and other pesticides. However, red spiders have no way to develop resistance to mineral oil, and mineral oil can also treat scale insects, soot disease and other pests and diseases.

Notes:

Spider mites are basically not done with Nahong has systemic conductivity, and the drug will not have an effect if it does not directly touch the eggs of the worm, and the place where the red spider occurs the most is the leaf peduncle on the back of the leaf, which is more difficult to spray, so the pure spray must be meticulous and thoughtful to ensure full infiltration, otherwise it will be useless.

There are two peak periods of red spider occurrence in a year, from April to June and from August to October, so prevention in advance when the peak is about to come will have a double effect with half the effort, such as early April and early August, which can be focused on prevention and control.

Many flower lovers are particularly annoyed by red spiders, especially those who raise plants such as moon season, hydrangeas, jasmines, gardenias and clematis, and often deal with red spiders. Spider mites are a species of leaf mites, which breed in poorly ventilated or dry environments, and raise flowers on enclosed balconies or windowsills, and plants and flowers are particularly susceptible to red spiders.

And the red spider is difficult to remove, one is because it has an extremely strong reproductive ability and a fast reproduction rate, reproducing a generation every three days; Second, because their eggs will lurk under the soil, and they will easily break out after the spring is warm; Third, because it is easy to develop resistance, it is difficult to remove ordinary insecticides.

Finally, we have to remind flower friends: when we raise flowers, we must pay attention to regularly check the state of the plant, once we find that there are some small yellow spots on the leaves of the plant, the leaves become rough, especially some small yellow or brown spots on the back of the leaves, it is likely to breed red spiders, and we must treat them in time.

1.Humid environment: Spider mites prefer to grow and reproduce in humid and noisy environments. If the walls, floors, ceilings, etc., in your home are damp, then spider mites may breed in these places.

2.Moderate temperature: Spider mites also need the right temperature to grow and reproduce. During the warmer indoor seasons, such as summer and spring, spider mites are more likely to breed and reproduce.

3.Presence of parasitic bumpers: Spider mites mostly live on insects and plants, and if there are a large number of these hosts near your home, the number of spider mites will also increase.

4.Lack of cleanliness: If the room is not clean enough, the breeding population of spider mites is more likely to increase. If the house is not cleaned for a long time, and clutter such as tableware is left indiscriminately, it will provide a place for spider mites to breed.

In order to control the breeding of red mites, it is first necessary to improve household hygiene, keep the environment dry and clean, and clean regularly. For items such as plants and indoor furniture, keep them dry and ventilated, clean and dust them regularly. If the RB breeds too much, it can be controlled with a special insecticide for the RB.

How to prevent and control it, because red spiders generally occur frequently in high temperature and arid environments, it is necessary to pay attention to timely prevention and control at high temperatures, and also change the maintenance environment. It can also be used to help eliminate its natural enemies, such as small bugs, heterochromatic ladybugs, phytosis mites, and bundle-feeding mite ladybugs. In addition, if the insect infestation is more serious, it is recommended to spray**, you can use 10% phenylpyridoxin emulsifiable concentrate 1000 times, or mix with emamectin benzoate emulsifiable concentrate 3000 times, so that the spraying effect will be better.

How does it affect the plant.

Spider mites have a wide range of sub-code greeting and mixed feeding habits, and can harm more than 110 kinds of plants. It is mainly a legumeaceae, solanaceae, cucurbitaceae and lily family. In spring, when the temperature rises and the plants begin to germinate, the female adult mites that are late in winter, the red spider begins to damage the plants, first to the leaves, and later to cover the entire leaves, and will also spread by the wind.

Usually July to August is the peak period, resulting in yellowing and whitening of fully ripe leaves, which seriously affects normal growth and may even lead to death.
