Hello! This symptom should be too many thrips on the flowers, sucking the nutrients of the leaves, leaving a mouth mark, thrips like to hide in the buds, you carefully look at the petals and the back of the leaves to see if there are thrips. If there are thrips, it is recommended to inject acetamiprid or ethyl spinosad and so on.

This is mainly eroded by some small fungal insects, and you can spray it with some anthelmintic drugs or sterilizers.

Aphids. It is a pest of stinging and sucking mouthparts, and often gathers on leaves, young stems, flower buds, apical buds and other parts to suck sap.

Harmful symptoms: make the leaves shrink, curl, deformed and unable to stretch.

After winter, adult aphids begin to parasitize and reproduce on new shoots, young leaves, and flower buds in early April, and winged aphids begin to appear in mid-April. Aphid reproduces twice a year, in mid-May and mid-to-late October. The temperature is around 20, and the climate is dry, which is conducive to reproduction.

Drug prevention and control: the active ingredient is imidacloprid, acetamiprid, thiamethoxam.

This month's disease is that there are insects.

You can go and spray with some sterilizers and insect repellents.

There is also some compound fertilizer to enhance the resistance of plants.

1. Rust: In the early stage of infection, small yellow-brown spots will appear on the leaves, and if not treated in time, the spots will grow larger and larger in the later stage, which will eventually affect the growth. You can spray powder rust solution every half a month, or sodium dirust solution, and generally spray it a few times.

2. Black spot disease: At the beginning, small black-brown spots will appear in the middle part of the leaves, and the infection will gradually affect the whole leaf in the later stage, which is generally common in the rainy season.

The white powder needs to be removed in time, and the leaves can be cut off directly if the situation is serious, and a little antimycomycin solution can be sprayed on the plant, and sprayed once every half a month.

4. Other diseases: In addition to the above-mentioned diseases, frost coal disease, mosaic disease, etc. may also occur, and the leaves need to be cut off first, and then sprayed with pesticides.

Insect pests are also more serious, red spiders and aphids are very common, are the main pests that harm it, you can remove it manually, or prepare some homemade pesticides, if the number is very much spray oxidized dimethoate emulsion solution, it can play a good effect.

Common pests and diseases in the moon season include aphids, divine worm disease and thrips. The prevention and control methods are introduced as follows:

1. Aphid disease

Aphids are stinging and sucking mouthparts pests that suck the sap of the plants after they reproduce on the plants that bloom in the moon, causing the leaves to become curled and slowly wilt and turn yellow. Spring and autumn are the high incidence period of aphid disease, and imidacloprid, acetamiprid, and thiamethoxam are used to spray and kill insects.

2. Thrips

Thrips are also an insect that feeds on plant sap, and the young leaves are sucked by thrips and cannot grow, and the tip dies severely. In addition to winter, the other three seasons are high incidence periods, and the prevention and control of thripping disease is usually done with ventilation, and the same agent can be used to kill aphids.

1. Black spot disease

In the early spring, you can spray the stone sulfur mixture and sweep the fallen leaves, keep a clean and tidy environment, you can avoid this disease, and you can spray Syngenta Huile at the time of the onset of the disease, and spray it every 5 days.

2. Powdery mildew

There is powdery mildew in the introduction of common pests and diseases and control methods in the moon season, the leaves will shrink and curl and other phenomena with powdery mildew in the moon season, and there will be white mildew on the surface, which mostly occurs in March and September in the autumn, the breeding process needs to maintain a ventilated environment, reduce the use of nitrogen fertilizer can avoid this disease, once suffering from this disease, you can use Guoguang black and white disease to spray every 7 days or so.

1. Aphids

Aphids are mainly distributed in the leaves, young stems and flower buds of the moon season, if not carried out in time, the leaves will curl the phenomenon, in the spring 3 May is the peak period of this insect infestation, it is necessary to reduce the temperature, maintain a dry growth environment, if this insect pest can be sprayed with imidacloprid.

2. Thrips

Thrips is one of the nocturnal insect pests, relying on sap sucking for a living, the damage to the moon season is relatively large, March is the peak period of this insect pest, it is necessary to spray Syngenta Huijian and other agents, in March and May is the peak period of this insect infestation, need to do a good job of control.

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.

1. Rust: In the early stage of rust infection, yellow brown spots will appear on the leaves, and if not treated in time, the spots will become larger and larger in the later stage, thus affecting the growth and development of the moon.

2. Black spot disease: black spot disease dies in the month and season, and black spots will appear in the middle of the leaves, which will gradually affect the whole leaf in the later stage, and black spot disease generally appears mainly in the rainy season. An appropriate amount of carbendazim solution can be sprayed on the leaves of the moon.

3. Powdery mildew: When you suffer from powdery mildew in the month, white powder spots will appear on the leaves, and other leaves will be infected, so the powdery powder needs to be cleaned up in time. In severe cases, the blades can be cut off directly.

You can spray an appropriate amount of anti-fungal drugs on the plants every half month**.

4. Insect pests: During the growth period, it is also easy to breed diseases and insect pests, such as red spiders and aphids. When pests are found on the petals of the flowers, they can be manually removed or sprayed with alcohol to repel the insects.

If the insect infestation is more serious, you need to spray more oxidized fruit emulsion to carry out**, which can achieve a good insect control effect.
