When the alarm comes to the high incidence period of red spiders, don't blame your flowers for not growing well.

It is found that there are white dots and red dots behind the leaves, and there are some things that look like spider silk, which makes people panic. There is no need to estimate what insect pest it is. It must be an outbreak of red spiders! Encountered flower friends will find that the red spider is small, but powerful, over and over again, difficult to deal with and difficult to manage!

What is the origin of the red spider?

If red spiders break out in flowers and plants, it first shows that there is something wrong with your planting environment. "High temperature, dryness, and lack of ventilation". With the collection of these three elements, it is very likely to induce red spiders to go out.

Are red spiders really related to spiders? Why have you never seen a spider in a flowerpot, just red and white dots? Be careful! Red spiders are not "spiders". They belong to the order Arachnida. It is very important to recognize this, which is why pesticides are not effective! It is like seeing an illness for many years and suddenly knowing that there has been no right remedy to the case!

Red spider, also known as spider mite, herbivorous mites, has a haustorium in its head and absorbs chlorophyll and other sap from leaves. It has strong reproductive ability and fast iterative speed. In addition to the amazing bisexual reproduction without a day off all year round, solitary reproduction can also be carried out, that is, no male mites can lay eggs and hatch, which can be described as "Xiaoqiang" in the micro world.

The red spider may be having a "family dinner" on your plant!

The white dots and red dots on the back of the leaves are red spiders growing at different stages. Maybe a red spider family is having a "family feast" on your green plant! You will see four growth forms of red spiders at the "family banquet": eggs, larvae, nymphs and adults. It is also said that red spiders have five growth stages: egg stage, larval stage, early nymph, late nymph and adult. Imagine that this scene is quite lively, sucking juice, spinning and netting, and being busy with spawning and hatching, pity the flowers and plants at home, and unwitting flower friends.

The truth of the red spider's immortal body!

Why are red spiders so difficult to catch up and kill? The following four truths can be summarized:

Truth one, red spiders are small, reproduce fast, adaptable, and easy to develop drug resistance.

Truth 2, red spiders are mostly harmful to the back of the leaves, which are easily ignored. If the chemical spray is not comprehensive, it will not play a role in killing mites at all.

Truth 3, a large number of red spiders spinning web defense agents greatly weaken the efficacy of the medicine.

Truth 4, an acaricide is not easy to cover multiple growth forms of red spiders at the same time.

No matter how strong the opponent is, there are weaknesses!

Although it sounds quite powerful, there is a saying that even a perfect person has his flaws, and even a strong person has his weakness. Red spiders, no matter how powerful the enemy also has its weakness, we need to use wisdom to give them a fatal blow. At the beginning of the article, it is also introduced that the three major causes of red spiders are "high temperature, dryness, and lack of ventilation." therefore, first of all, timely adjustments should be made to the environment, "cooling, moisturizing, strengthening ventilation" and changing the external environment.

In addition, for small seedlings and small pots, flower friends who are affected by a small number of pots can try to rinse and soak. Red spiders are afraid of water. As soon as you find it, rinse it with water twice a day in the morning and evening, focusing on the back of the leaves, for about a week. Remember to rinse each leaf and check it from time to time. While soaking, as shown in the following picture, tie up the basin and soil with plastic bags, and completely soak the damaged flowers and plants in water.

This method is suitable for small seedlings and small pots, and there is no problem for three or five pots to do so. however, you have to say that if there are a large number of pots, the incident occurred in a courtyard planted in the ground, or if the plants are large woody vines, this method will not work. Can only sit back and wait for death?

The nemesis of the red spider, test the miracle medicine for yourself!

If not much, rinse the red spider. Once the situation develops to a large scale, and a plant is damaged to 20%, it is necessary to come up with the must-kill recipe summed up by the Squirrel. The following are three kinds of mite control drugs tested by yourself, and the effect is quite good. This can also be regarded as the ultimate mace for killing mites. Spray must persevere, fishing for three days and drying the net for two days is not good, intermittent will produce drug resistance instead. In addition, acaricides must pay attention to the proportion, it is better to be light than strong, otherwise it will cause drug damage and make things worse.

The three nemesis of red spider: avermectin, acaroid mite + Jinmanzhi, dacarine

Avermectin, after application, the adults, nymphs and larvae of mites will be paralyzed after contact with avermectin, and the peak of killing usually occurs only three days after application, but it will hit the red spider on the day of application and stop feeding immediately to prevent further damage to the leaves. Avermectin can last for 7 to 15 days, and the control effect can reach more than 90%. It is the first choice to destroy red spiders.

Aika mite + gold full branch, this needs two kinds of medicament to use together. First of all, use Aika mite, which is sticky in the bag and needs to be extracted with a syringe. 1 ml of Aika mite needs to be diluted with 2500 ml of water, that is, about 600ml of water per drop. Three days later, begin to use Jinmanzhi, using 1 ml to 1500 ml of water. Also need to pay attention to spray in place, the back of the leaf is the most important, you can tilt the flowerpot to rotate the pot spray, at the same time, the front of the leaf, branches, basin soil surface should be sprayed, for serious leaves can be removed, but must not bare leaves only bare rod. And remember to spray and wash your hands with soap.

Dacarine, acaricidal spectrum can be used for all kinds of mites, has a good effect on the whole growth period of red spiders, and has obvious quick killing effect. Dacarine is not affected by the change of temperature, no matter it is used in early spring or autumn, it can achieve the effect of killing mites. However, the efficacy will be affected by light conditions and unstable, spray is best in the evening and night.

Most of the red spider spray is a 7-day cycle, such as Monday spray, Tuesday stop, Wednesday stop, Thursday spray, Friday stop, Saturday stop, Sunday spray. Only by going through such a process can the larvae hatched by the adults and eggs of the red spider be chopped all over the door.
