How To Prevent Tree Peony Pest Infestations？

How to prevent tree peony pest infestations？

1、 Agricultural prevention and control

Strengthen maintenance:

Keep the growth environment of peonies clean, regularly remove dead branches, leaves, weeds, etc., and reduce the lurking and spawning sites of pests.

Maintain ventilation and transparency, avoid excessive humidity, and reduce the occurrence of pests and diseases.

Reasonable fertilization and watering:

Fertilization should mainly use organic fertilizers, supplemented by chemical fertilizers, to avoid excessive application of nitrogen fertilizers and improve the disease resistance of peonies.

Watering should be done in moderation to avoid water accumulation and prevent root rot, which can attract pests.

Timely pruning:

Regularly prune the branches and leaves of peonies to maintain ventilation and transparency of the plant, while cutting off diseased and insect infested branches to reduce the breeding of pests.

2、 Biological control

Protecting and utilizing natural enemies:

Ladybugs, sand flies and other natural enemies are important natural controllers of peony pests and should be protected and utilized.

It is possible to provide habitats and food sources for natural enemies by planting plants that they like.

Microbial control:

Utilize beneficial microorganisms such as bacteria and fungi to control pests, which can disrupt their physiological functions or inhibit their reproduction.

3、 Physical prevention and control

Artificial hunting:

For a small number of pests that are easy to catch, manual killing can be used.

For example, using the false death or phototaxis of pests to hunt during the day or night.

Light induced killing:

Utilize the phototaxis of pests and use lights to lure and kill them at night.

4、 Chemical control

Scientific medication:

When necessary, low toxicity and efficient pesticides can be used for prevention and control.

Pay attention to using pesticides correctly according to the instructions, avoid excessive or repeated use, and avoid unnecessary harm to the environment and plants.

Precise pesticide application:

Choose the appropriate timing and method of pesticide application based on the occurrence pattern and characteristics of pests.

For example, applying pesticides during critical periods such as the hatching and nymph stages of pests can improve control effectiveness.

5、 Soil treatment

Soil disinfection:

When changing soil in spring and autumn each year, the soil can be disinfected first to prevent pests and bacteria from harming peonies.

Deep plowing of soil:

By digging deep into the soil, it is possible to disrupt the habitat of pests and reduce their population.
