CATDOLL : CATDOLL: How to kill spider mites?

Question 1: How to use the simplest method to completely eliminate flower spider mites? Pepper water: Take 50 grams of red dry pepper, add 1000 grams of water and boil for 15 minutes, filter and spray the supernatant. It can prevent and control whiteflies, aphids, spider mites, etc. Fengyoujing: Dilute 600D800 with Fengyoujing and spray. It can prevent and control aphids, scale insects, spider mites, moths, butterflies and other larvae. Garlic: Take 250 grams of purple garlic, soak in water for 30 minutes, mash to extract juice, dilute with water about 10 times and spray immediately, it can prevent and control aphids, spider mites, earthworms, etc. Red spider mites are highly resistant to drugs and are prone to recurrence. They can be bombed in turns by multiple methods.

Question 2: How to eliminate red spider mites? In home flower cultivation, you can use the following methods to prevent and control red spider mites:

(1) Soak citrus peels in 10 times the amount of water for a day and night, filter and spray the peels on the plants. This can also prevent and control aphids. If you use it to water flowers, it can prevent and control nematodes in the soil.

(2) Mix 15 grams of laundry detergent, 15 milliliters of 20% sodium hydroxide, and 7.5 kilograms of water, then spray. Check after 1D2 days. The mortality rate of adult and nymphal red spider mites is 94% to 98%.

(3) Take 50g of wood ash, add 2500g of water and stir thoroughly, soak for two days and nights, filter, then add 3g of washing powder and mix thoroughly before spraying, once a day for three consecutive days, and spray again for three days after one week. This can eliminate the second generation of pests and can also prevent and control piercing-sucking pests such as aphids and scale insects. Putting it into the soil can prevent and control maggots.

(4) Light a plate of mosquito coils and place it in the pot of diseased plants. Then tie the pot tightly with a plastic bag. After about an hour of fumigation, both eggs and adults can be killed.

. Red spider mites are mites, also known as spider mites, commonly known as red spider mites or fire dragons, short-bearded mites, and are common diseases on flowers. They specifically harm flower leaves and flowers, and have a wide distribution range. Their hosts are very common: including herbs, woody plants, fruit trees, and wild elms, photinia, and pine needles in bonsai. The body of the red spider is very small, only the size of a needle tip, less than 1 mm, round or oval, with a body color of orange-yellow, reddish brown, etc. The flesh is only a small red dot, and the orange-red transparent spherical eggs can only be seen under a magnifying glass. The body of the red spider is segmented, but the segments are not obvious. It is wingless. The red spider goes through four stages in its life: egg, larva, nymph, and adult, but does not go through the pupa, which is an incomplete metamorphosis. Red spider mites have a strong reproductive capacity, and generally more than 10 generations can occur in a year. They start to cause harm in March and April every year, and the damage is serious in June and July. In the case of high temperature, high humidity and poor ventilation, red spider mites reproduce very quickly. Its nymphs often gather on the back of leaves and buds of some flowers, sucking juice with piercing-sucking mouthparts to harm plants. In the early stage, the leaves lose their green color, and the leaf edges roll up, causing them to scorch and fall off, causing the flower buds to shrink early, and in severe cases, the plants die. In addition to crawling by themselves, the spread of red spider mites is also important through wind, rain, and operation. Most species of red spiders live on the lower surface of leaves, and a few live on the upper surface of leaves. Female adults or eggs overwinter in the cracks of bark or soil on branches and trunks.

2. Common species: The main types of red spiders that harm flowers include citrus red spider, common red spider, cinnabar spider mite, two-spotted spider mite, etc. The following mainly introduces the characteristics and harm of hawthorn red spider. Hawthorn red spider harms flowers and fruit trees such as elm leaf plum, mallow, cherry, peach, crabapple, and crabapple. The living habits are not very active. They gather on the back of the leaves to cause harm, and spin silk to make webs, causing chlorotic spots on the leaves. In severe cases, the leaves will burn and fall off. The female adult is 0.5 to 0.7 mm long, 0.3 mm wide, and dark red. The male adult is 0.4 mm long, 0.2 mm wide, and orange-yellow. Hawthorn red spiders can generally produce 5 to 9 generations per year, and the fertilized female adults overwinter in the cracks of the bark of branches or the cracks in the soil at the base of the trunk. In the spring of the following year, the overwintering adults come out of hibernation and harm young and tender tissues such as buds. In the hot and dry summer, they reproduce quickly and in large numbers, which is the peak period of the year.

3. Prevention and control methods: To prevent and control red spider mites, you should pay attention to observation at ordinary times. When you find abnormal color of leaves, especially when there are gray-yellow spots on the leaves, you should carefully check the back of the leaves. If individual leaves are damaged, you can remove the insect leaves; when more leaves occur, you should spray the medicine as soon as possible. It is best to use a magnifying glass when checking to facilitate observation; for flower beds, weeds should be removed frequently and dead leaves and leaves should be destroyed to eliminate overwintering insects; when more red spider mites are found, chemical agents should be used for early prevention and control. Preventing and controlling early damage is the key to controlling the rampant pests in the later stage. For chemical control after infection, you can spray 40% trichlorodicofol wettable powder 1500 to 2000 times liquid. The spraying should be uniform, meticulous and thoughtful, so that the leaves, branches and fruits are evenly covered with the liquid. In winter, you can use Baume 3 to 5 degrees lime sulfur mixture to kill the overwintering adults, nymphs and eggs on branches and trunks, especially the egg killing effect is better.

Question 3: How to kill red spider mites? Red spider mites are a common disease.

This insect is very small, less than 1 mm, round or oval, orange or reddish brown. It is not easy to be found due to its small size. Once it is found, the damage to the flowers is often quite serious. This insect uses its mouthparts to pierce the leaves of flowers and suck the juice, which destroys the chlorophyll of the flowers, causing the leaves to show grayish yellow spots or patches, and the leaves become withered and yellow, or even fall off.

The red spider has a strong reproductive capacity, and can reproduce a generation in about 5 days at the fastest. This insect likes a hot and dry environment. Therefore, under hot and dry climate conditions, it reproduces rapidly and causes serious damage. The insects often gather on the back of flower leaves to spin silk and weave webs to cause damage. In addition to crawling by itself, the spread of red spiders is also an important way for wind, rain and handling.

To prevent red spiders from harming flowers, you should pay attention to observing flowers at ordinary times. If you find that the color of flower leaves is abnormal, you should carefully check the back of the leaves. When individual leaves are damaged, you can remove the insect leaves; when more leaves are damaged, you should spray pesticides as soon as possible for prevention and control. Commonly used pesticides include cypermethrin, trichlorodimethoate, dimethoate, cypermethrin, and cypermethrin. For home flower cultivation, you can prepare a flower sprayer. Add cypermethrin, cypermethrin, or cypermethrin to 400 ml of water (equivalent to 2000 times liquid), or add cypermethrin or dimethoate 8 drops (equivalent to 1000 times liquid), shake well after adding the medicine, and then spray. Spraying requires uniformity and thoughtfulness, especially pay attention to spraying the back of the leaves. It is best to move the potted flowers outdoors when spraying. If you spray indoors, do not approach food or utensils. After each use, pour out the excess liquid and wash the sprayer with clean water.

How to treat red spider mites with pepper water

This method is also widely used. If red spider mites appear on flowers, you can spray them with boiled peppers. The effect is also very good, and the raw materials are easy to obtain and generally available at home.

But it should be noted that all these methods should be used in small amounts, not too large amounts. It should be done step by step, and spray the red spider mites several times to naturally remove them. Acting too hastily will be harmful to the flowers!

You can also soak the tobacco leaves in water, control the amount, and use the spraying method!

Question 4: How to kill red spider mites? This method is safe and environmentally friendly, spraying with Junmei Biological Air Isolation Membrane.

Question 5: Can the killing method kill red spiders?

Question 6: Effective methods to kill red spider mites Since mites adapt to drugs quickly, they also develop resistance quickly. Therefore, no matter how effective the drug is, it should be used only once per crop per year. By switching between different drugs, the resistance of mites can be interfered with. At the same time, when choosing drugs, it is necessary to understand the true chemical composition of each drug to avoid passively and unknowingly repeating the same or the same function of acaricide.

In addition, we should pay attention to winter garden cleaning, collect dead branches, diseased branches, weak branches, fallen leaves, and fallen fruits, and burn them to reduce the source of pests and diseases in the orchard. When cleaning the orchard, you can use 250 times of 45% sulfur suspension, which can kill bacteria and have a good control effect on mites, and the cost of use is lower than other miticides. When insects and mites occur at the same time, it is advisable to use avermectin or rural bromophos.

Third, you should choose a spray gun with good pressure and fine droplets, and mainly spray the mist to the bottom of the leaves, so as to improve the control effect. Finally, in addition to the above-mentioned drugs, there are also miticides on the market, such as: pyridabenz, monocarboxamidine, bromocyclon, spirocyclon, etc., which are all drugs for controlling mites and may have a good control effect on mites. But the problem is that we should adhere to the principles introduced above to achieve scientific use of drugs and achieve better control effects.

Question 7: How to kill red spider mites on flowers? It is best to go to the flower shop and buy a pack of plant insecticides such as Dust Mite or Dust Mite. One pack in a spray bottle, spray the back of the leaves, leaves and branches of the plants, and the rest in the pot soil. Spray three times in a row, about once a week.

Question 8: What medicine is effective in killing red spider mites? Damanling, Ceramide, Nisolan, etc. are all OK, but Ceramide is the best.

Habits:

It mainly harms many vegetable crops such as Solanaceae, Cucurbitaceae, Leguminosae, and Liliaceae.

There are many types of red spider mites on jujube trees. The dominant species in jujube orchards with intercropping of dates and crops is the truncate spider mite, which parasitizes a wide range of plants, including jujube trees, cotton, corn, beans and a variety of weeds and vegetables.

Red spiders lay about 100 eggs once a year, which begin to hatch a month later. The mother spider waits day and night and is willing to be the first food for her children, teaching them how to hunt but at the cost of herself.

There are 13 generations in a year, and the eggs overwinter. The overwintering eggs generally begin to hatch in early March and all hatch in early April. After overwintering, the first to third generations mainly reproduce and harm on ground weeds. After the fourth generation, they harm jujube trees, intercrops and weeds at the same time. The overwintering period begins in mid-to-late October. The eggs mainly overwinter in the bark seams of jujube tree trunks, ground soil seams and weed bases. After the overwintering eggs hatch in early March, they leave the overwintering sites and move to weeds that sprout in early spring. The longest distance that the newly hatched mites can crawl within 2 days is about 150 meters. If they cannot find food within 2 days, they may die of hunger. In late April, when the jujube trees sprout, some of the red spider mites on the ground weeds begin to move to the trees to harm the jujube trees. The main way of transfer is to crawl up along the tree trunk. All active insect stages of the red spider mites can be transferred.

Question 9: How can I completely eliminate red spider mites? Thank you! The simplest and most cost-free method is to find dozens of cigarette butts, soak them in water and apply or spray them on the leaves, once every three days. After several times, the larvae that hatch from the eggs can be killed together. Of course, dimethoate, dichlorvos, and mosquito fly cleaner can kill them several times. Poor ventilation is the main reason for the breeding of red spider mites. After improvement, the effect is obvious.

Pesticides can completely and effectively eliminate red spiders. If there are a small amount, you can use tobacco soaked in water + laundry detergent to spray and kill. In poor ventilation or hot weather, red spiders are easy to breed, so pay attention to observation.
