Iron tree disease is manifested as a small light brown spot at the beginning of the leaf infection, and then spread to a similar round or irregular shape, the lesion ** is dark brown to gray-white, the edge is reddish-brown, the lesion is black dots, due to the connection between the lesions, it forms a patch, causing the leaf to die and break.

In high temperature, dryness, poor ventilation, leaves are susceptible to scale insects, control can be removed with a brush brush or timely spray with 50% dimethoate emulsion or 50% monocrotophos or 80% dichlorvos emulsifiable concentrate 1000 times.

After <> insects grow on the iron tree, you can use scissors to cut off the infected leaves to avoid further deterioration of the situation, you can also spray the diseased area of the iron tree with diluted alcohol to avoid the rest of the healthy branches and leaves from being infected by the disease, and you can also spray 21% killing emulsifiable concentrate on the iron tree to remove the insects on the plant, so that the iron tree grows healthily.

1. Cut off the diseased leaves.

Iron trees are susceptible to the erosion of scale insects during the growth stage, which will hide on the back of the leaves of the iron tree and eat the branches and leaves of the plant, so that the iron tree is infected with black spot disease and other diseases.

2. Spray alcohol.

3. Spray the agent.

When breeding iron trees, you need to regularly observe the growth state of the plant, if you find that the branches and leaves of the iron tree are harmful insects, you need to kill 21% of the emulsifiable concentrate on the iron tree, so as to avoid the rest of the healthy branches and leaves are infected by the mountain disease, and wait for the leaves of the iron tree to no longer yellow and black, which means that the pests are removed.

Iron tree insects need to be properly pruned after the plant, cut off the part of the plant that suffers from insect infestation, and also need to spray the plant properly to eliminate the residual pests on the plant, and also need to ventilate the plant regularly to improve the ventilation of the plant growth environment, so that the plant can grow healthily.

1. Prune the plants

Iron trees need to be pruned after they are insected. First, choose scissors with a sharp edge, and then use scissors to cut off the most affected parts of the plant to prevent the pests from eating more healthy branches and leaves. At the same time, after pruning, it is necessary to apply carbendazim solution to the pruning wound of the plant to help the wound heal as soon as possible.

2. Spray the agent

Iron trees also need to spray the appropriate amount of insecticides for the plant after the insects, to eliminate the pests on the plant, and at the same time need to pay attention to the number of spraying when spraying the plant, generally in the case of serious plant insect infestation, it is best to spray the plant every morning, noon and evening, for about three days.

3. Ventilation treatment

Iron tree insects may be poor ventilation of the plant growth environment, providing a better growth environment for pests, so in the later stage to prevent iron tree insects, it is necessary to regularly ventilate the plant to improve the ventilation of the plant growth environment, so that the plant can resume normal growth as soon as possible.

4. Later maintenance

In the later maintenance of iron trees, it is necessary to provide appropriate water for the plants, keep the soil in a moist state, and also need to provide appropriate nutrients for the plants, improve the growth rate of the plants, and pay attention to the amount of fertilizer when providing nutrients for the plants, so as not to cause fertilizer damage to the plants due to excessive fertilization, and cannot grow normally.
