What should I do if there are insects on the moon flowers?

Common insect pests and treatment methods of moon flowers:

The large moth is a very miscellaneous pest, which harms ornamental plants such as plum blossoms, plums, roses, yueji, camellias, osmanthus, pomegranates, cherry blossoms, crape myrtles, peach blossoms, and irises. The larvae eat the leaves with holes or missing cuts, and in severe cases, all the leaves on the plant are eaten, and only the leaf veins remain.

The hatchling larvae first gnaw on the host plant and first gnaw on the plant tissue fragments and connect them with filaments to form a sac, which can be formed after 3 to 4 hours. The female is in the sac. After the sac is formed, the larvae begin to feed.

When the larvae feed and move, the head and thorax protrude out of the sac and carry the sac. The insect grows and the pouch lengthens and expands. July of the year is the most harmful.

In November, the larvae overwinter. During overwintering, the larvae tie silk loops to the branches or veins of the plant.

The pesticide control is to spray 1000 times of 90% trichlorfon stock solution or 1000 times of 80% dichlorvos emulsifiable concentrate in early and mid-July, and the effect is very good.

Green blind bug symptoms

The green blind bug harms many flowers and trees such as yueji, chrysanthemum, dahlia, bunch of red, hibiscus, hibiscus, pomegranate, peach blossom and so on. Adults and nymphs prick the young leaves, leaf buds and flower buds of plants such as Yueji with mouth needles. The stinged leaves show black spots and holes a few days later, and when the damage is severe, the leaves twist and shrink.

When the bud is stung, black-brown sap oozes from the victim. After the tender tip of the leaf bud is damaged, it is charred black and cannot produce leaves.

Pesticide control is in early and mid-April when a large number of nymphs hatch, with 80% dichlorvos emulsifiable concentrate 1000 times, or 40% dimethoate emulsifiable concentrate 1000 times, or 50% pine borer emulsifiable concentrate 1000 times, or more or 50% phosphine emulsifiable concentrate 2000 times, or 20% pyrethrin 2000 3000 times liquid, or 50% dibromophos emulsifiable concentrate 1000 times liquid spray control. When spraying, pay attention to spraying hidden places such as the back of the leaves, and nearby weeds should also be sprayed at the same time.

Archaeoptera spp.

Symptoms Leaf mite is a common leaf mite on roses. The mouthparts suck the juice on the back of the leaf, first injuring the lower leaves, and then gradually expanding to the upper leaves. The affected leaves appear gray-white dots or white patches, and in severe cases, the leaves die and fall off.

Pesticide control 1) During the dormant period of the winter moon season, Baume 3 5 degrees stone sulfur mixture can be sprayed to kill the overwintering mites on the branches;

2) Spray 40% dicofol EC 1000 times, or 50% parathion EC 1500 2000 times during the hazard period. Be careful to spray the back of the leaf sufficiently.

The insect pests of the moon season are generally nothing more than aphids and green insects, aphids can be trapped, and green insects can be manually killed. It is best not to use pesticides. That is, polluting the environment, causing bad odors, and not conducive to management.

When watering, put a few drops of wind oil essence in the water can cure insects, try it.

If you don't want to use pesticides, spray saline, which has some effect, I learned from the calendar.

1. Soak in water with tobacco, soak overnight, and spray on the branches and leaves the next day.

2. Add some laundry detergent to the laundry detergent and spray.

Or a mix of the two.

There are many varieties of moon flowers, and the flowers are colorful and colorful, and they are very beautiful to plant at home or on the balcony. But what if there are bugs on the flowers? Next, I will introduce the main solutions for you, let's take a look!

Causes and prevention methods of insects growing on seasonal flowers

1. No ventilation.

The moon flowers are generally placed in a ventilated place, and generally there are pests and diseases in the moon season, which is largely due to the fact that there are many other plants planted around, or placed in the corner of the balcony, which is not ventilated and breathable. Therefore, it should be placed in a place where the moon flower can breathe air freely. It would be best if there was a terrace, which could be planted on the terrace or in a small flower bed.

2. Wenru shouts too much or waters too much.

Most of the causes are high temperatures, too much watering, or poor ventilation. Aphids, in particular, are most likely to grow when the weather is warm, and there are some soil contaminated by insect infestations. You can prune the branches, cut off the leaves and branches that have insects, throw them away, and wait for it to grow new branches and buds.

3. Aphid disease.

Generally, when the temperature is higher in autumn and when the weather warms up in spring, it is easy to grow aphids. If you have more, you can only use insecticides, such as imidacloprid and so on. It is best to prune off the leaves that are full of bugs.

Prune the branches in the winter as well.

4. Red spider.

If it's not particularly serious, you can try it with soda or dish soap spray, and I heard from flower friends that mosquito scented can deal with red spiders, but I haven't tried it yet. If it still doesn't work, you need to use an insecticide. There are flower insecticides and the like.

There are also carbendazims and the like, taking turns to spray and kill.

5. Powdery mildew.

If patches of white powdery stuff appear on the leaves of the moon, water will not wash them off. Diseased leaves are removed and sprayed with white fungus, and it is said that the effect of scrubbing sulfur powder with water is also good. There is also black spot, where small brown dots appear on the leaves and then gradually increase, which can be diluted with chlorothalonil and sprayed multiple times.

Prune off sick branches and leaves in time.

6. Scale insects.

The beetles that have been flowered in the moon season mainly include the white wheel scale, the Japanese turtle wax scale, the red wax scale, the brown soft wax waiter scale, the blowing cotton scale, the chaff shield scale, the snake eye scale, etc., and its harmful characteristics are to suck the sap of the young stems and young leaves of the moon season, resulting in poor plant growth, mainly caused by high temperature and high temperature, poor ventilation of the old oak locust, and poor light. It can be sprayed with 2000 times of 25% chlorfen decompotable powder at the peak of nymph hatching.

Tips

These kinds of pests and diseases are more common in the moon season, and there are some pests and diseases, you can also spray several more insecticides and fungicides, if you really can't do it, put it on the open-air balcony for a period of time, anyway, it can't die in the sun, it will be more robust in the wind and rain, and it will be more robust. Or change the pot of the moon flowers, change the soil, and replant them.

1. Drug spraying.

Different insects need to use different drugs, such as stinging moths, they need to be sprayed with trichlorfon or pyrethrin emulsifiable concentrate, scale insects need to be sprayed with parachlorpin wettable powder, and aphids need to be sprayed with oyster forest.

2. Cooling and ventilation.

Insect growth in the moon season is likely to be caused by high ambient temperature or humidity, so after this phenomenon, we need to immediately improve the maintenance and management for it, it is best to cool and ventilate the plant, to avoid it from growing in a hot and humid environment, so as to effectively avoid it from breeding pests.

3. Strengthen lighting.

It is a sun-loving plant, so it is also necessary to strengthen the light at this time, it is best to maintain it in a sunny place, to ensure that it has no less than 6 hours of light exposure every day, but in summer to prevent it from being exposed to strong light.
