What are the insect pests in the monthly season? What are the common diseases of the moon season?

Long-tube aphids.

The main characteristics of damage are flower plants such as moon season and rose. In order to damage the flower buds, new shoots, and young leaves, suck the juice, so that the branches grow slowly and the flower type becomes smaller. The excrement of insects can also induce coal pollution disease and affect the growth and development of the month.

2) Control method In the dormant period of the moon and season, cut off the aphid branches, spray 1000 times of stone sulfur mixture or pine borer, 1000 times of acemethamidophos. In spring and autumn, during the occurrence of aphids, spray 2000 times of pyrethrin solution or 50% 1000 times of aphid mist.

There are more such pests in the moon season, and all of them will die with a little "small white grain".

The common diseases of the moon season are as follows:

1. Black spot disease.

Dark spots are one of the most common and classic diseases of the moon season, and there is no fatal effect on the moon season. Even in the most severe cases, the leaves fall out, but only affect the phased growth and flowering of the plant, and the branch pulling and flowering can resume in a short period of time.

2. Powdery mildew.

Powdery mildew is the second most common classic disease in the monthly season, second only to black spots in frequency, but it is far more lethal than black spots. Powdery mildew begins to occur in new shoots and shoots (including buds), and in severe cases, new shoots and shoots become melanistic and necrotic, or even die of the whole plant.

3. Seasonal rust.

The effect of rust on the moon season is similar to that of black spot and is not fatal.

4. Black rot.

Black rot does not occur often, but it is not easy after the onset of the disease, and the slightest carelessness will lose branches or even scrap the whole plant. If the planting environment is damp and not ventilated, it is very prone to disease, and there are cuts left by pruning, and the incidence will increase. The disease will be black from the part or end of the branch and gradually spread, ** in time to die in the month.

5. Rhizobia.

Rhizobia is not common, and it is not fatal to a single plant in the monthly season, but it is highly contagious, and the plant will age and weaken after infection, with few leaves and no flowers, which is equivalent to scrapping. Of course, the greatest lethality is the fear formed in the psychology of the flower grower. Once infected with rhizobia, the branches are aging and weakened, and there are almost no new branches and no flowers, and the phenomenon of dead seedlings appears.

The underground part has fewer roots and fewer new fleshy roots.

Although the moon season is not so delicate compared to the rose, it is impossible to raise the moon season flower without pests and diseases, so when taking care of the moon season in daily life, you need to understand the pests and diseases that it often encounters, and you can solve the problem easily when you know the disease. Daily maintenance of monthly flowers to regularly water fungicides, found that the diseased leaves should be cut off in time, spray fungicides every week, spray about 3 4 times in a row, you can complete fungal diseases.

Here are a few common pests and diseases and how to deal with them.

1. The most common infestation of moon flowers is aphids, which usually gather on buds and leaves, and will suck sap and wilt branches and leaves. In the early stage of aphids, if the number is small, it can be rinsed with water, but it is necessary to avoid long-term moisture of the leaves, otherwise it is easy to be infected with fungal diseases.

Aphid control is very simple, and you can see good results by spraying it once with insectoprid.

2. Red spider is a common disease of the moon season, red spider mainly sucks the juice of the moon flower leaves, causing the moon season leaves to lose green and yellow, affecting photosynthesis, red spider reproduction speed is very fast, the harm to the moon season is very great. Spider mites mainly occur in poorly ventilated environments, when it is found that the leaves have pinholes and large color uneven spots, it is necessary to pay attention to check the back of the leaves, when there are red, black or white dots on the back of the leaves, then it can be concluded that it is a red spider.

Spider mites are more afraid of water, and after getting them, they can be scrubbed with water or rinsed with a water gun.

It is best to use drugs**, the drugs have to use acaricidal drugs, such as pyridoxine, Ica mite, etc., and the general insecticides have a weak effect on spider mites.

3. Moon season black spot disease, at first, the leaves appear small brown spots, and then gradually develop and expand, into black-brown spots, and finally cause the whole leaf to turn yellow and fall off. It is most common in summer.

The prevention and control methods are mainly prevention, and in the spring, it should be sprayed every half a month to prevent zeb. At the same time, the diseased leaves should be removed in time, and then the whole plant and the surface of the potting soil should be sprayed with zeb + mycloconazole. It can also be sprayed with mancozeb, carbendazim, etc., and it is recommended that 2 kinds of drugs be used together for better results.

Spray every 3-5 days, 2-3 times in a row to complete the **.

4. Powdery mildew in the early stage, the leaves infected with the germ are curled at the edges, and white powder can be found on the back of the leaves, which will spread to the entire leaves, stems and buds if not timely, and a large area of white powder will appear. It is highly common in spring and autumn, and poor ventilation is the main cause of powdery mildew, so attention should be paid to keeping the environment ventilated and the inside of the plant well ventilated during the breeding season.

When it is found that the leaves are infected with powdery mildew, the leaves should be removed in time and then sprayed with fungicides. Zinc dyzeb + mycloconazole for the treatment of black spot can also be used for powdery mildew, and it is recommended to use stone sulfur mixture for outdoor planting, and the effect of powdery mildew is better.

Spider mite: Once a spider mites appear on the flowers, you need to immediately cut off the dense branches and leaves of the pests, and then spray it with avermectin and drugs such as mite, baafen, and insect mite. Aphids:

When the quantity is relatively small, you can remove them directly by hand. When the quantity is relatively large, it needs to be sprayed with imidacloprid and avermectin alternately for **.

Mosaic mites and their control

Leaf mites are also called red spiders, and there are two main types of leaf mites that harm the moon season: one is cinnabar leaf mites, which are insect red, and the other is two-spotted leaf mites, which are insect yellow to yellow-green. Generally, leaf mites will parasitize on the back of the leaf to suck the juice, and there will be many small yellowish-white spots on the front of the leaf, and then the leaf will slowly turn yellow and finally fall off.

In severe cases, the entire flower bud and branches will be full of leaf mites. It can be evenly sprayed with Hongshi sulfur mixture at the stage of insect stinging, and sprayed with avermectin and cremect, baafen, and insect mite net in the early stage of occurrence.

Flower aphids and their control

Aphids will gather on the buds, young leaves, and flower buds of the moon season to suck their juice, and in severe cases, there will be honey oily black secretions, which will reflect the quality of the flower and the growth of the moon season. When aphids lay eggs in autumn and winter for overwintering, imidacloprid and avermectin can be used alternately for control.

Thrips and their control

When thrips live in young leaves, they will die at the top of their old age, making them unable to grow. If it feeds on the back of the leaf and excretes brown material, the back of the leaf will be deformed, and the sides of the midrib will also appear gray-white or gray-brown stripes, deformed and curved. You can spray the agent for **, choose the one containing imidaclopsam, acetamiprid, thiamethoxam and other active ingredients.

Mosaic peaks and control

The larvae eat away at the leaves of the moon season, produce holes, feed quickly, and in severe cases, they will gnaw all the leaves and even tender shoots. It can be sprayed with drugs such as phosphine and perchloroemectin benzoate in the early stage of insect pests.

Rose stalk bee and its control

It occurs every year, and lays eggs under the inner diameter epidermis in April and May, and after incubating the eggs, it burrows into the stem, and then cuts downward along the cambium spiral to feed until it reaches the lower part of the branch, and when it matures, it will make a pupal chamber in the branch, which is barrel-shaped. An effective control method is to prune the diseased shoots and prune downwards until the larvae are found, and then they are eliminated.

Seasonal flowers are short-fronted locusts and control

The short-fronted locust will bite the leaves into many holes, and two generations occur in one year, laying eggs in winter for the winter, and hatching eggs in May and June. It can be sprayed with 50% thiophos 1000 times, the mortality rate is very high, and the effect is very good.

The above is my summary of the insect pests and control methods of the moon flower, I hope to help you.

Insect pests can be used to treat aphids, if you have red spider disease, then you can use pyridoxin to deal with it, scale insects are a common insect pest in the month and season, and there is also a carbendazim, which can solve most of the insect pests that are affected by the moon season, and can be effectively controlled.

1. Pyridoxrid

What medicine can be used for the insect pest of the moon season according to the specific insect pest of the month season to target the medicine, insectoprid is specially used for the first month of the aphid a kind of agent, the aphid is very harmful to the month season, and the reproduction rate is extremely fast, the leaves of the month season may be eaten up by the aphids if the treatment is not timely, and the aphid is the best agent to solve the aphids.

2. Da mite

Spider mites are also a common insect pest, they generally grow on the front and back of the leaves, mainly by sucking the cell sap in the leaves, this pest can be solved with pyridoxine, the drug is very strong, the damage to plants is very small, and the pest has a certain target.

3. The cocoon must be treated

Scale insect is a kind of insect pest that all plants are very susceptible to infection, and the moon season can not escape its invasion, this insect mainly eats leaves, stems and other tender places of plants, scale insects can be seen with the naked eye, so if you don't want to use medicine, you can use tweezers to pop it, and if the number is too much, you can use the scale to kill the scale insect with scale.

4. Carbendazim

This is a very wide range of drugs, it can ** and defend against a variety of diseases of plants, carbendazim powder mixed with water and sprayed on the leaves of the moon, it has almost no damage to the plant, and the efficacy is very strong, it can effectively control the insect pests of the moon, it also has a certain preventive effect, can reduce the invasion of the later insect pests on the moon.

Here are a few common diseases in the moon season:01 powdery mildew02 Pests03 Yellow leaves04 rotten rootsThe reason for rotten roots, I think everyone knows that overwatering is the most common, because some friends do not have a good grasp of the amount of water, and it is easy to water too much if they are not careful, resulting in rotten roots and yellow leaves. Personally, I suggest that if you really don't know how to grasp the amount of water, you can use a flower and grass moisture detector to measure it, or use a watering can to water slowly along the soil, and see that the bottom of the pot is gradually drained out, which means that it has been watered thoroughly.

The main diseases of moon flowers are powdery mildew, black spot and so on; The main insect pests are aphids, scale insects, red spiders, leaf rollers, longhorn bees, leaf wasps, saw bees, etc.

1) Prevention and control methods of powdery mildew.

1) Strengthen cultivation management: Frequent inspection, and immediately cut off and burn diseased branches and leaves. Control watering Apply less nitrogen fertilizer and prune carefully to ventilate the inner chamber of the canopy well.

2) Punishment prevention and control: Spray 1000-2000 times of powdery rust solution or 70 times of methyl tobuzin 1000-1500 times solution during the onset period. In early spring, the sulfur mixture is sprayed before the well is constructed, and 0 1 - 10 can also be usedPrevention and control of UJ wet sulfur powder suspension.

Usually spray once every 5-7 days, and spray 1 every 2-3 days when you are seriously ill

Times. The method of making a suspension of sulfur powder is to wrap the sulfur powder in a coarse cloth and knead it in clean water to form a suspension of sulfur powder.

2) Prevention and control methods of black spot disease.

1) Select varieties with strong disease resistance.

2) Remove dead branches and leaves.

3) Choose a ventilated and light-transparent environment for cultivation and strengthen fertilizer and water management.

4) Pharmaceutical prevention and control with 200-300 times of Bordeaux liquid, spray once every two weeks for prevention. Spray 30-5 before germination. Stone sulfur mixture.

At the onset of the disease, spray 7 days of methyl toprux 1000 times, or 75 days of bacterium clear 1000 times, or 50 carbendazim 800-l000 times, or 50 dyceonium solution. At the beginning of summer, 10-14 days spray 1 Bordeaux liquid 1 time.

3) Aphid control methods Frequently inspect the plants, and kill or remove and kill the aphids in time after they are found. When it is severe, use 40 dimethoate l 200 times solution, or 90 crystal trichlorfon 1000 times solution, or aphid pine milk 1500 times solution, or 2 5 rotenan orange 1000-l 500 times liquid spraying.

4) Prevention and control methods of scale insects When scale insects first appear, use a toothbrush or bamboo skewer to remove them. In large areas of severe insect growth, pruning can be done by renewing the pruning and burning the insect branches, or changing the cultivation site. In the nymph stage, spray with 1000-1500 times of 40 dimethoate, or 800-1000 times of 50 malathion emulsion, or 1000-2000 times of 50 of phosphine; In the dormant period with 30-5.

Stone mixture spraying, and pay attention to the protection and use of natural enemies, such as Australian ladybugs, large and small red ladybugs, etc.

5) The prevention and control method of red spider first remove fallen leaves and weeds, or implement nursery irrigation to extinguish the fire and overwinter the insect source. Spray 0 2 during the occurrence period. —0 30 stone sulfur mixture or 40 dicoplasmidol emulsion 2000 times, or spray 20 triclodifol alum 800 times.

6) The control method of stem borer pests is combined with pruning, crushing the eggs and killing the hatching larvae at the oviposition crack, and cutting off the tender shoots of diseased branches and insect pests in time. During the larval hatching period, spray 20 times of 3000 times of chrysanthemum cheese, or 2500 times of 40 dimethoate to protect the use of parasitic wasps.

7) The control method of leaf curl insect is to manually kill the larvae, or spray it with 40 dimethoate 2500 times, or 90 crystal trichlorfon l 000 times.
