The hard-earned plants have all become the lunch of the pests, who does not have heartache! In order to compete with the pests, the babies must first understand and identify them, the so-called self-knowledge and know the other ~ the following followed by the flowers and flowers together with the pests' old nest!
Pest species
According to the location and way of pests harming flowers, they can be divided into the following categories.
1. Leaf-eating pests:
When such pests are harmed, they eat the leaves of flowers in large mouthfuls, causing leaf damage, and in severe cases, the leaves can be eaten all of them.
Common such pests include yellow thorns, scarab beetles, etc., as well as harmful animals such as snails and rat women, which bite leaves and young shoots.
2. Stinging insect pests:
Such pest mouthparts, such as syringes, can pierce into the floral plant tissue (leaf or tender tip), suck the nutrients of the flower plant tissue, make the leaves dry and fall off, and the affected leaves appear to be green, white or brown.
These pests are small, varied and sometimes difficult to detect. Common are aphids, mesozoans, whiteflies, thrips, leaf mites and so on. Some of these pests can secrete honeydew, and some can be divided into waxy substances. It not only pollutes the leaves and branches of flowers, but also easily leads to coal pollution disease, and it looks like a thick layer of pulverized coal has grown on the leaves and branches.
The mites in this type of insect can spit out wire knots, and when they are severe, the nets can adhere to the leaves and branches, which are easy to find, and at this time, it is also a period of considerable pests.
3. Drill borer pests:
This type of pest borer moth infests the branches and stalks of flowers. Hollow out the stems and branches and cause them to die.
Such as Chrysanthemum, Dahlia Borer, Rose Stem Bee and so on. Some are harmful to the blade, and the blade can be seen in the tunnel of the borer, causing the blade to dry up and die.
4. Soil cultivation pests:
These pests live throughout their lives in the shallow and superficial layers of the soil.
Flower infestations often cause the leaves to see tunnels or die of borers, such as ground tigers, golden needle worms, and caddisflies.
Inspection and identification
1. Check the worm feces:
Check for insect droppings around the ground and on the branches where the flowers and trees are placed. For pests that burrow into the branches, check the fecal holes for fecal and wood chips scattered on the ground. Most of the insect dung and wood chips discharged by the tianniu are filamentous; the wood beetle is granular and sticky into strings.
2. Check excrement and secretions:
It can be checked for oil stains in the branches and leaves of flowers and trees, and it is found that these substances are generally produced by pests such as honeydew and wax, mainly aphids, aphids, and whitefly prick sucker pests.
3. Check the eggs:
Large eggs and egg masses can be seen with the naked eye, and tiny eggs can be seen with large mirrors. Eggs are generally laid in branches, leaves, bud axils, etc., such as red spider eggs are mostly laid on the back of leaves; canopy caterpillar eggs are laid on branches; aphid eggs are mostly in the bud axils; locust eggs are found in the soil.
Due to the different living habits of various pests and the different spawning sites, they are sought in their spawning sites in order to further identify pest species hazards to show early control.
4. Branch inspection:
For some pests that will fly when frightened, they will be found by flapping or shaking the branches and leaves. Red spiders are small and difficult to distinguish with the naked eye, but they can be placed on white paper in representative branches and leaves, and then patted to determine whether there are red spiders on the white paper.
5. Check the victimization:
Check the leaves and branches of the flowers and trees for any places that have been bitten and damaged, such as holes, missing carvings, screens, etc.; or have curly leaves, or have foreign body growth, dead tips or dead branches on the branches.
6. Check the pests in the soil:
First check the soil surface for any abnormalities. For example, the slugs walk on the topsoil, and there are protruding marks on the surface of the soil. Some adult scarab beetles lurk under the topsoil of the flower rhizome and can be found by pulling out the topsoil.
Prevention and control methods
Grass and wood ash soaking method:
Use 500g of grass and wood ash, mix with water 2.5kg, soak for a day and night, filter out impurities, and spray the affected plants with filtrate, which can effectively kill aphids.
Vinegar leaf rubbing method:
With 50ml of vinegar (rice vinegar), the cotton ball is soaked in vinegar, and then the vinegar-stained cotton ball is gently rubbed on the leaves of the flowers and trees, which can not only kill the shell worm, but also make the leaves that have been damaged by the shell worm return to green and bright.
Alcohol leaf wiping method:
Gently and repeatedly wiping the leaf surface of the infested mesenchymal with alcohol can remove the mesophyllum, and even the larvae that are invisible to the naked eye can be completely killed.
Iodine application:
If the main stem of the woody flower is rotten, the rotten part can be scraped off first, deep into the xylem, and then coated with iodine wine, and then applied again every 7-10 days, not only can be completely cured, and over time, the main trunk mammo is prominent, and the more it shows the prominence of Canggu, which is very interesting.
Soda spraying method:
The control rate of powdery mildew in flowers such as moonflower, chrysanthemum, hydrangea, wood hibiscus, melon leaf chrysanthemum and other flowers can be finely sprayed with 0.1% baking soda (nahco3) solution.
Washing powder solution spraying method:
The specific preparation method is to mix well with 1g of washing powder and 100-180g of water. Spray once a week, continuous treatment 2-3 times can control the infestation of mesozoans and aphids. However, it should be noted that neutral washing powder should be used, and if you find that the young leaves have burns, you can spray some water in time to rinse off the residual liquid.
Mothball burial method:
2 mothballs are sewn into a small cloth bag and buried in the roots of flowers and trees to prevent dry insect pests such as tianniu.
Wind oil essence spray method:
The liquid spray diluted by wind oil essence is 600-800 times, which can control aphids, red spiders, mesozoan nymphs and moth and butterfly larvae, etc., and the insect control effect is 90%.
Sweet and sour solution spraying method:
Spraying potted flowers with 2g of sugar, 3g of vinegar and 95g of clear water mixture can kill a variety of pests and germs, and has a good effect on yellowing caused by iron deficiency in camellia and rhododendron.
