The rose sticks to this bug, which is more lethal than the red spider.

Rose has always been elegant and beautiful, but once there are pests, there is nothing we can do. The first ones to bear the brunt are red spiders and Xiao Hefei, which spread widely and fast. in addition to these two kinds, there is also a kind of insect that can not be ignored. it is more lethal than the red spider, but often we don't think so.

Apart from the red spider and Xiao Hefei, what kind of insect pest has so much "lethality"? Different from other pests, this kind of insect is small and difficult to find at first, but it has basically bred a large area when it is noticed. The troublesome bug is aphids. Everyone may be familiar with it, so how to control aphids quickly and effectively to ensure the healthy growth of plants?

First of all, let's talk about what aphids are, wingless parthenogenetic adults, long 2.2mm, green, yellowish green and brown. Tail cone-shaped, with 6-7 curved hairs. The winged parthenogenetic aphid is 2mm in length, black in head and chest, light green in abdomen and small in size. Aphids are very small and difficult to identify.

Therefore, as long as we find that there are dense bugs on the twigs or buds of the rose, which are basically at rest, and their bodies are similar to common aphids, we might as well treat them as aphids first, so as not to hesitate to cause aphids to break out.

Aphids can reproduce 10-20 generations a year and survive in winter. They can survive through eggs at the base of leaf buds or flower buds, and some parthenogenetic aphids survive the winter on rose plants. They reproduce with the increase of temperature in spring and spread everywhere, and will decrease appropriately in the summer high temperature season, but it will happen again in September.

Generally speaking, it takes about 10 days to complete the reproduction of a generation when the temperature is low in early spring and late autumn, but it only takes 4-5 days in summer, so even if the number of aphids decreases in summer, we still can't take it lightly.

Aphids mainly suck the juice of rose leaves, especially to the young leaves and shoots of rose. The leaves of the damaged plants are withered and yellow and fall off, and their excreta can also induce coal fouling disease and cause deformities of flowers, leaves and buds. Aphids are also the main pests of virus transmission.

Now that we have figured out the aphids, the prevention and control of aphids is a lot easier. If aphids occur in the rose planted on the balcony at home, a small amount of aphids can be caught manually, and then the flowerpot is tilted under the faucet to wash the rose branches. Or it is also a good way to use yellow plastic plates to induce adhesion after being oiled.

Drug control can be selected when the number of aphids is large, and it can be treated by spraying 1500 times diluted liquid and spraying 1-2 times. If it is not convenient to use medicine, you can also prepare it by yourself. There are several ways. Let's talk about it briefly below.

(1) use 50 grams of fresh chili or dry red wine chili peppers, add 30-50 grams of water, cook for about half an hour, and sprinkle the damaged plants with its filtrate.

(2) 3-4 grams of detergent, 100 grams of water, stirred into a solution, sprayed with a spray can for 2 times for 3 times, the prevention and control effect is excellent.

(3) use "wind oil essence" to add water 600 murine 800 times solution, spray with sprayer, make the insect body sell potion. The effect of killing aphids is more than 95%, and there is no drug damage to the plant.

(4) the washing powder, organic liquid fertilizer and water specially used for rose are mixed into a mixture of 1 ∶ 2 ∶ 800, which can be used to spray plants, which can kill insects and fertilize two birds with one stone.

Aphids are easier to control than red spiders, and there are many methods, most of which are easy to be wiped out. As long as you observe carefully and use the right methods, you will not be afraid of aphids.
