Flower enthusiasts must be very anxious! As for what to do when Ixora gets pests, it is actually very simple. We first determine which kind of pest it is, and then solve it accordingly. Regarding pest and disease control for Ixora, the editor will discuss insect pests and diseases separately.

(1) Pests and Diseases of Ixora, 3 Insect Pests

Scale insects, red spiders, aphids

1. Scale insects

Damaged parts: This insect is one of the main pests of Ixora. It mainly harms tender leaves and sucks the sap of the flowers.

Symptoms of infestation: Ixora leaves change from green to grayish green, and finally to yellow. In severe cases, the branches and leaves are covered with scale insects, causing the entire plant to wither and die.

Solution: When there are few scale insects, they can be directly scraped off or picked off with a toothpick; if the density of scale insects is high, use 550% malathion, 40% dimethoate 0.1% solution, etc. for spraying and killing. Once scale insects occur, the harm is very great, so in daily life everyone mainly focuses on prevention.

2. Red spiders

Damaged parts: One of the main pests of Ixora. It mainly harms the underside of leaves and survives by sucking the sap of Ixora leaves.

Symptoms of infestation: The plant will become nutritionally imbalanced, and symptoms such as yellowing and even falling off of Ixora leaves may appear.

Control method: After confirming this pest, rinse the whole plant thoroughly with a large amount of water, then spray a specialized pesticide, such as 20% dicofol emulsifiable concentrate 2000 times solution, and spray several times.

3. Aphids

Damaged parts: Indoors, aphids are the main pest of Ixora. They mainly harm leaves and pierce and suck the sap of newly sprouted branches and leaves.

Symptoms of infestation: Leaves become stiff, which affects the normal growth of the plant after early spring. After flowering, the flowers are very small, or flowering is abnormal.

Control method: When there are few aphids, tobacco powder and plant ash can be sprinkled on the insects and leaves, and after about 1-2 hours, rinse clean with water; when there are many aphids, use 2.5% derris emulsifiable concentrate 1200 times solution for spraying and killing.

(2) Pests and Diseases of Ixora, 3 Diseases

Leaf spot disease, anthracnose, sooty mold

Regarding pests on Ixora leaves, after reading the above content, I believe everyone knows how to deal with it! However, in addition to being damaged by insects, diseases also constantly harm Ixora. It is understood that there are mainly 3 kinds of diseases of Ixora: leaf spot disease, anthracnose and sooty mold. The specific symptoms and control methods are as follows:

1. Leaf spot disease

Damaged parts: Leaf spot disease is a fungal disease. It mostly occurs in late autumn when the weather turns cold. It is one of the main diseases of Ixora and harms the plant's leaves.

Symptoms: Pale yellow and red-yellow spots appear on the leaves, and after expansion they become round or oval; if the environment is relatively humid, black granular matter may appear on the lesions, and in the later stage the leaves dry up and fall off.

Control method: After discovering this disease, everyone should promptly remove diseased leaves and residual water to avoid excessive water. In severe cases, use emulsifiable concentrate 1000-1500 times solution for control, or 50% carbendazim wettable powder 500 times solution, spraying 2-3 times every 7-15 days, and results can be seen after several applications.

2. Anthracnose

Damaged parts: This disease is one of the main diseases of Ixora. It mainly harms leaves. The pathogen overwinters on diseased parts or diseased leaf residues.

Symptoms: Nearly round or irregular round lesions appear on the leaf edges. As the disease worsens, the color of the lesions turns dark brown and spreads around. At this time, the center of the lesion is grayish white and the edge is dark red, which is easy to identify.

Control method: When diseased leaves are found, remove them immediately to reduce the source of disease; before onset, spray 25% carbendazim wettable powder 500 times solution, about once every 10 days, and after 3-4 sprays it is basically improved.

3. Sooty mold

Damaged parts: Another disease of Ixora. The parts it harms are branches and leaves.

Symptoms: Dark brown dirty spots appear on branches and leaves, then gradually expand, forming a large area of black soot-like fungal layer, affecting the plant's photosynthesis and thereby causing Ixora to be unable to grow normally.

Control method: When diseased branches and leaves are found, everyone can wash them with 1000 times carbendazim solution or burn them. This disease focuses on prevention. Usually everyone should strengthen indoor ventilation to reduce the air humidity in the greenhouse so as not to cause the disease to spread.

Regarding pest and disease control of Ixora, the editor has introduced it here. I believe everyone will know what to do when encountering pests or diseases in the future! Overall, during the growth process of Ixora, pests and diseases are unavoidable, so to avoid unnecessary trouble, flower enthusiasts should keep in mind the above symptoms and control methods.
