Raising flowers in the family is easy to appear to attract red spiders, recently many people are saying that if you find that the red spiders are found to be tricky, do not spray, spraying is not good for the body, to use water to operate, then what is the effect of water flushing? Can it be used as a method of insecticide? Today Xiao Qi told you in detail, if you plant more flowers, don't try, it is easy to flood, if appropriate, why is the greenhouse not a large area to use?
Red spider it is afraid of water, most of the bugs are afraid of water, such as ticks, they are afraid of water, but you go to use water flushing effect is not obvious, if you go to the faucet against the flower flush, is able to wash down the white whitefly, tick shell insects and red spiders and the like, but where to rush? Rush to the surface of the pot soil, rush into the crevices of the pot soil, and when you are finished, the insects will climb to the branches, and use water to flush, even if you take it to the outside to wash, it will be a small amount of red spiders on the surface of the pot soil or the front and back of the leaves and the branches.
Because the red spider is very small, you can not wash thoroughly when you flush with water, there will definitely be residues, you go to wash three times or four times there will be residues, maybe after the flush is obviously reduced, but he breeds ten or twenty, and even the later three or five days of time are full, because this is a physical method of deworming, not insecticide, the so-called deworming is just to flush the insects to another place, do not let him on this plant, if he has eggs, the eggs are also difficult to wash off.
If you have one or two pots of flowers, there is a pot of insects and the trick is not obvious, you go to wash it with water, a small amount can be washed clean, but if it is a large number of flowers, there is a pot of flooding after you go to flush, it is not clean at all, and the eggs rush to other places can easily lead to other plants crawling full, in the end as long as the red spider is recruited, the leaves will inevitably be damaged, which will affect plant growth. Now most flower friends are on the balcony indoor flowers, there is no place to flush, and the indoor ventilation is often poor, some even seal the balcony, then as long as a residual insect egg, the reproductive speed is quite fast, and so he reproduces the plant will be damaged, simply not worth the loss.
Whether it is indoors or outdoors raised plants, found that the insects are sprayed in time, after the drug he can be completely killed by the drug, will not reproduce, if it is raised indoors, you can go to find a watering can to mix with the drug, take it outdoors to spray a drug, stay outdoors for an hour or two, wait for the drug smell to evaporate clean you then move indoors, generally three times can be completely killed, common red spider medicine has avidinidium worm, imidacloprid and other mites can be, red spider resistance is relatively strong, You keep using a drug and it develops resistance.
So we can use it at intervals, such as the first time we use imidacloprid to kill, the second time we use arvidine to kill, a variety of drugs are used in rotation, it is not easy to produce resistance, so that the red spider we raise can quickly kill, no longer reproduce, then the newly grown leaves are good, if you have been breeding, your whole plant may be completely yellow leaves, and finally the whole plant will die.
Raising flowers and insecticides must use insecticides, now insecticides are low-toxicity, there is no problem in getting outdoors, if the plants are raised to recruit some large insects, such as the kind of green insects produced by moths, this can be artificially removed, found in time to clean it up, as long as there is no egg will not reproduce, but those small whitefly, red spiders and other mites, as far as possible to spray, spraying is the most effective effect. Do you know now? Don't blindly light credit water flush, it can be washed clean, can not wash clean your plants will multiply in a large area, in the end all the plants are out of the question, more than worth the loss.
