Pest control of Dryopteris Dryopteris

The growth period of Dryopteris is not easily affected by diseases and insect pests. However, if the growth environment temperature is too low, ventilation, poor light, and air humidity is too high, it is very easy to be infected with Botrytis cinerea and blight, accompanied by red spiders, shell insects, slugs and other pests, resulting in leaf wilting, drooping and even death.

Prevention and control methods:

In order to avoid the above situation, we should often check the leaves to ensure that the leaves are not too wet, pay attention to ventilation and ventilation, when there is stagnant water in the basin soil, stop watering, there are dead seedlings, and dump them together with the basin soil in time. Pesticide control can use 1000 times of 70% methyl topiramate wettable powder, 1000 times of nematodes, 4000 times of agricultural streptomycin spraying Dryopteris Dryopteris, its pest control and plant quality can achieve a good effect.

The above is the introduction of the matters needing attention and the prevention and control of diseases and insect pests. If you want to know more, please pay attention to the four Seasons Plant Network!

Diseases and pests of Dryopteris Dryopteris and its control

The Diseases of Dryopteris and its Control of Root Rot

Root rot is one of the diseases of Dryopteris Dryopteris. The occurrence of root rot is mostly related to the environment. Excessive air humidity or stagnant water in flowerpots may lead to root rot. The harm of root rot is greater, the occurrence of root rot will lead to root rot, the root is an important part of the plant, rot may spread to this plant, need to pay special attention.

When root rot occurs in Dryopteris Dryopteris, it needs to be controlled in time. Trim the roots, or spray them with medicine. The chemicals that can be used include mancozeb solution, Ningnanmycin solution and other agents, which can be sprayed after dilution.

Grey mold, blight

These two diseases are also common diseases of Dryopteris Dryopteris, and the causes are also related to the environment. Generally, diseases are easy to occur in the case of low temperature and poor ventilation.

Botrytis cinerea and roadside disease occurred in Dryopteris Dryopteris, timely measures should be taken to control it.

Insect pests of Dryopteris and its control of aphids and red spiders

When the growth environment is poor and can not meet the growth needs of Dryopteris, Dryopteris may produce the harm of aphids or red spiders.

When these pests occur, some insecticides can be used to kill insects.

Shell insects, slugs

Pests such as shell insects and slugs also occur frequently because of environmental reasons, which can lead to the withering and even death of the Phoenix tail fern.

Pruning Protection of Dryopteris Dryopteris

During the growth period, the Phoenix tail fern will grow too fast, resulting in too dense leaves and weak growth. when the light is poor, there will be a phenomenon of decay, which can be pruned in time to remove the dead leaves, dead leaves and yellow leaves of the Phoenix tail fern. Avoid decay and keep the plant beautiful.

Matters needing attention in the Culture of Dryopteris Dryopteris

In the growth process of Dryopteris Dryopteris, there will be aphids, red spiders and other pests, as well as root rot to harm the health of plants. Need to use chemicals to prevent and control, and do a good job of daily management.

Winter yellow leaves

When the temperature is too low, the Phoenix tail fern will appear a lot of yellow leaves, at this time should be careful, do not rush to cut off the yellow leaves, yellow leaves can also transport their own stored nutrients to the new leaves.

The above is about the breeding methods and matters needing attention of Dryopteris Dryopteris, but Dryopteris not only can be raised in soil, but also can be cultivated in water. Let's take a look at the hydroponic culture of Dryopteris.
