Common garden plant pests and diseases Garden plant pests and diseases

<> the growth process of garden plants has been plagued by pests and diseases, pesticides are often used in the past pest control work, but there is no strict control of pesticide quality and dosage, the awareness of comprehensive prevention and control is relatively lacking, resulting in the pest control effect is not ideal, some pests and diseases appear repeatedly, but also pollute the atmosphere, soil and water environment, endanger urban residents.

of good health.

1.Pests and diseases are diverse

At this stage, some cities are too aesthetically pleasing, ignoring plant growth habits, blindly introducing exotic varieties, and wantonly matching different kinds of plants, so that the types of pests and diseases increase significantly, and the phenomenon of cross-infection occurs frequently, and it is difficult to control the problem of pests and diseases in a targeted manner, and the technical means used cannot be effective. Once the outbreak of pests and diseases spreads in a short period of time, it will quickly infect the surrounding healthy plants, causing disease in the roots, stems and leaves of plants, decaying plant communities, and greatly reducing the ornamental value.

2.The harm lasts for a long time

Transplanting plants into city streets and parks, using artificial means to intervene in plant growth, resulting in these garden plants being less resistant than naturally growing plants, plus high-rise buildings.

Blocking, automobile exhaust pollution, etc., will slow the growth of garden plants, and the probability of pests and diseases is higher. The suddenness and concealment characteristics of pests and diseases determine that when garden plants are eroded by pests and diseases, it takes a long time to be discovered, and the best treatment time is missed, and garden plants continue to be harmed.

3.Stubbornness of pests and diseases

In fact, some stubborn pests and diseases are difficult to be completely eliminated, and garden plants are frequently attacked by pests and diseases during the growth period, and the growth state is poor and the mortality rate is achieved.

On the high side. This requires the use of advanced instruments and equipment for the maintenance of garden engineering to dynamically monitor the growth of plants, and detect pests and diseases as soon as possible, otherwise the recalcitrant pests and diseases will cause damage to the plant growth system, cause disease and death of plants, affect the play of plant functions, and reduce the overall benefits of garden engineering.

In garden plants, the biggest characteristic of the occurrence of pests and diseases is the development of spreading. Once pests and diseases occur, they will spread to the entire garden in a short time. So be sure to pay attention to prevention.

Generally, the growth rate is relatively fast, the spread rate is relatively fast, and there are more types of pests and diseases, which will affect crops and soil.

Answer: In some green spaces, the garden plants are of single species, densely planted, and pests and diseases are easy to spread, so it is difficult to control them. Cities are densely populated and are not suitable for conventional, polluting pest control methods.

Summary. Hello, the main types of pests and diseases of common garden plants are:

1 American white moth, the American white moth mainly uses larvae to feed on plant leaves, its feeding amount is large, and when the damage is serious, it can eat all the leaves of the host plant and eat the bark.

2. Boxwood silk leaf borer, the host of the insect is limited to the boxwood family, and the adult flight ability is weak, and the long-distance transmission mainly depends on artificial seedling transportation.

3. The larvae of the poplar fan boat moth are harmful in spring and summer. The larvae feed on the leaves of poplars and willows, and in severe cases, they eat up the leaves, affecting the growth of trees.

4 Stinging moths, if stung by their stingers, will be very painful, and the venom is acidic.

5. Acacia inchworm, which is also a relatively common pest and disease.

Please list the main pests and diseases of 5 common garden plants.

Hello, the main pests and diseases of common garden plants are 1 American white moth, American white moth mainly uses larvae to feed on plant leaves, its feeding amount is large, and when the damage is serious, it can eat all the leaves of the host plant and eat the bark. 2. Boxwood silky leaf borer, the host of this insect is limited to the boxwood family, and the adult flying chain return is weak, and the long-distance transmission mainly depends on artificial seedling transportation. 3. The larvae of the poplar fan boat moth are harmful in spring and summer.

The larvae feed on the leaves of poplars and willows, and in severe cases, they eat up the leaves, affecting the growth of trees. 4 The stinging moth is sleepy, and if it is stung by its stinger, it will be very painful, and the venom is acidic. 5. Acacia inchworm, which is also a relatively common pest and disease.

What plants do they mainly harm, and it would be nice to say one plant for each insect.

Can you be in more detail? For example, one plant corresponds to one insect.

The American white is often infested by birch and boxwood silky leaf borer, and the host of this insect is limited to boxwood trees, and the poplar fan boat moth mainly infests willows. The stinging moth is mainly trees such as Sijiqing, and the national acacia inchworm repentance and prudence is the main attack on the filial piety locust tree.

Garden plants need to be strengthened in the usual maintenance, to be reasonably pruned, so that it has a good ventilation environment, and to remove the diseased leaves in time to avoid infection, during the maintenance period should be timely fertilized, and to be watered appropriately, after the occurrence of pests and diseases need to use the corresponding drugs.

Common diseases of garden plants.

Powdery mildew: When garden plants are growing, powdery mildew will occur due to the growth environment of high temperature and humidity, especially boxwood, pentagonal maple, cochin, hawthorn, osmanthus, poplar and other plants, after the onset of the disease, the leaves will have white powder, and then will become light yellow or black small particles.

Coal pollution disease: garden plants will also have the occurrence of coal pollution disease, which occurs more commonly on flowers and trees, and affects photosynthesis after the onset of the disease, and will reduce the ornamental value and economic value, and generally crape myrtle, peony, citrus sedan chair, camellia and other plants are more susceptible to infection.

The main insect pest of garden plants.

When garden plants are growing, there are often insect pests such as elm purple flower insects, which are extremely unfavorable to the growth of plants, larvae and adults will harm the leaves, and will be adsorbed on the leaves to eat the leaves at ordinary times, resulting in a large number of leaves falling off.

Garden plant pest control.

Garden plants need to be strengthened in the usual maintenance, to be reasonably pruned, so that it has a good ventilation environment, and to remove the diseased leaves in time to avoid infection, during the maintenance period should be timely fertilized, and to be watered appropriately, in the occurrence of pests and diseases after the key needs to be used
