What to do when the Madagascar jasmine gets bugs? Pest and disease control - do not use insecticides carelessly
As the Madagascar jasmine (Stephanotis floribunda) grows more and more popular, more and more people are growing it, but those who do not pay attention to the cultivation methods and precautions for the Madagascar jasmine will find that the plant they are growing has bugs. If handled improperly, not only will the bugs not be cleared away, it may even lead to the death of the Madagascar jasmine. So what should be done when the Madagascar jasmine gets bugs? Below are several correct methods, as well as precautions for pest and disease control of the Madagascar jasmine.
What to do when the Madagascar jasmine gets bugs
When learning about why the leaves of the Madagascar jasmine turn yellow, many people tend to overlook one point, and that is pests, which are also one of the reasons for yellowing leaves. So what should be done when the Madagascar jasmine gets bugs? There are mainly three steps we need to take: the first step is to find out the cause of the pests; the second step is to kill the pests; and the third step is to do a good job of pest and disease control for the Madagascar jasmine.
1. Causes of the Madagascar jasmine getting bugs
Usually the causes of the Madagascar jasmine getting bugs are the following: insufficient ventilation, a harsh growing environment, too much watering, insufficient fertilizing, and so on. You can troubleshoot according to the correct planting methods and your own actual situation, because a healthy Madagascar jasmine will not grow bugs. Things like being shaded by surroundings, insufficient light, and too much watering can all lead to the Madagascar jasmine getting bugs.
2. Pest removal
After determining the cause, what should be done when the Madagascar jasmine gets bugs? Reasonable measures need to be taken to remove the bugs that have already appeared. The removal mentioned here is not just clearing away the visible bugs, but also includes some invisible eggs. The following methods can be used to clear them.
a. If the leaves become deformed, sticky, curled, and yellow, there is a very high probability that aphids have appeared. They may also attract ants. The accurate method of treatment is to use cotton soaked in alcohol to dab at the aphids, then spray the aphids with relatively strong mint leaves, and afterward move the Madagascar jasmine outdoors, and move it back indoors after ventilating.
b. If the Madagascar jasmine has scale insects that are oval in shape and have white wax on them, they generally appear on the leaf stems of the plant. You can use a cotton swab dipped in alcohol to kill the insects, and then just pay attention to pest and disease control for the Madagascar jasmine.
c. Go to a flower shop to buy specialized flower medicine, and then spray the Madagascar jasmine that has bugs. Do not use common household insecticides, because although this can kill the eggs, it will also cause the leaves to turn yellow, because the concentration contained in them is too high.
3. Do a good job of pest and disease control for the Madagascar jasmine
After all the previous work has been completed, we also need to pay attention to doing good prevention and control work, because if you ignore it after clearing away the bugs, they may still appear again in the future, so it is very necessary to prevent trouble before it happens.
Generally, the causes of pests and diseases in the Madagascar jasmine are mainly leaf diseases such as leaf spot and leaf blight caused by Cercospora, as well as root rot and stem rot caused by Fusarium. Right after the disease first appears, drugs such as carbendazim can be used for control.
The main point of root rot control is that the drainage of the substrate must be good, and watering should maintain an alternation of dry and wet. Then place the plant in a bright place with a slightly higher temperature, and pests and diseases can be very well prevented from happening again.
What to do when English ivy gets bugs, English ivy pest and disease control / 2 pests, 3 diseases
English ivy is a plant with very high ornamental value. It can be seen almost everywhere in people's lives and makes a great contribution to urban greening. However, no matter how high its ornamental value is, if it encounters pests and diseases it will still show yellowing and withering. Regarding what to do when English ivy gets bugs and how to carry out English ivy pest and disease control, the editor below will take everyone through it.
I. What to do when English ivy gets bugs / Find the cause and treat it accordingly
Regarding the question of what to do when English ivy gets bugs, if you encounter it, you first need to check what kind of pest or disease it is, find the symptoms, and then treat it accordingly. Below there is information on the onset characteristics and control methods of various pests and diseases, which everyone can take a look at.
II. English ivy pest and disease control
1. Scale insect pests
In English ivy pest and disease control, scale insect pests are a relatively common kind. They mainly harm the leaves of the plant and will slowly suck the sap of the leaves. When this pest appears, many yellow spots will appear on the leaves, and as time goes on the leaves will fall off early.
Control method: This pest mostly appears in humid environments, so when growing English ivy you must pay attention to ventilation. When treating this pest, we can use a 1000-fold dilution of 40% omethoate for spraying to kill them.
2. Red spider mite pests
The red spider mite is a pest with a very small body, less than 1mm, and it is generally very hard to find with the naked eye. This pest mainly harms the stems of English ivy. It will slowly absorb the plant's sap, and as time develops it will cause the plant itself to lose nutrients, resulting in leaf drop and the plant withering and dying.
Control method: This pest has an extremely strong reproductive capacity, so as soon as it is found it must be dealt with immediately. We can use 10% fenbutatin oxide and pyridaben emulsifiable concentrate to spray the whole plant, generally once every 7-10 days, and after 2-3 times this pest can basically be completely eliminated.
3. Phytophthora blight
Phytophthora blight mainly harms the leaves of English ivy. In the early stage of the disease the leaves will gradually turn brown, and as time goes on they will shrivel and rot. This disease also has extremely strong contagiousness and will also contaminate the soil.
Control method: If you encounter this disease, you must deal with it as early as possible, otherwise once the pathogen spreads it will be very difficult to deal with. When treating this disease we must first disinfect the soil, then use a 800-fold dilution of 25% metalaxyl wettable powder to irrigate and treat the plant.
4. Leaf spot disease
Leaf spot disease, as the name suggests, is a virus that harms leaves. In the early stage, very small dark spots will appear on the leaves. If not dealt with for a long time, the spots will gradually expand, and they will also spread to the leaf stalks and stems, finally causing the entire English ivy plant to rot.
Control method: The best time to treat this disease is in the early stage of onset. If too much time passes it will be very difficult to cure thoroughly. The most direct treatment method is that we can use a 500-fold dilution of 20% zhongshengmycin suspension concentrate to spray the plant.
5. Gray mold disease
Gray mold is a disease that many plants are easily infected with. When it occurs, the main feature is that brown or black spots appear on the edges of the leaves. If not treated for a long time, a gray mold layer will gradually form, causing the English ivy to rot and die.
Control method: This disease is easiest to solve in the early stage of onset. We can directly cut off the infected leaves, then use a 500-fold dilution of 75% chlorothalonil for sterilization, generally once every 10 days. After 1-2 times it can be completely cured.
Regarding the question of what to do when English ivy gets bugs, after reading the above I believe everyone already knows how to solve it. In fact, in the process of growing plants, the most important thing is still care. As long as care is proper, pests and diseases rarely appear. The editor has introduced English ivy pest and disease control up to here, hoping to bring everyone some help.
What to do when ivy gets bugs, ivy pest and disease control / Finding the cause is key
Ivy is not a very delicate plant, and its ability to adapt to the environment is relatively strong. However, during the growth process, if you do not understand the cultivation methods of ivy, it will inevitably be troubled by pests and diseases. If the ivy we grow gets bugs, what should we do? Mastering certain methods of ivy pest and disease control is very important.
What to do when ivy gets bugs
1. Leaf roller moth
Symptoms: The larvae of the leaf roller moth hide inside the leaves of ivy and feed on the mesophyll. Transparent gray-brown membranes appear on the veins and upper epidermis, excrement of the leaf roller moth appears on the leaves, and afterward the leaves become dry, yellow, and fall off.
Control methods: (1) Use bundles of grass or piles of grass to trap overwintering mature larvae; (2) before the larvae curl the leaves at the end of the 2nd instar, spray a 1000-fold dilution of 80% dichlorvos emulsifiable concentrate, or a 1500-fold dilution of 60% dimethoate emulsifiable concentrate.
2. Red spider mite
Symptoms: The leaves of ivy become dry, yellow, and whitish. On the leaf surface appear adult mites that are red, pear-shaped, with one black elongated spot on each side of the back. They usually occur in early June or July. If not controlled in time, they will endanger the growth of ivy. They are one of the most harmful pests in ivy pest and disease control.
Control methods: (1) When the leaf color of ivy is found to be abnormal, pay attention to observing and checking the underside of the leaves, and if red mites are found the diseased leaves should be removed; (2) Spray a 2000-fold dilution of 20% clofentezine wettable powder, or a 2000-fold dilution of 15% pyridaben emulsifiable concentrate.
3. Aphids
Symptoms: Aphids will appear in the young leaves and young stems at the top of the ivy plant. If aphids grow on the leaf stems, the plant will show slow growth, yellowing, and even deformation. They are one of the most common pests of many plants.
Control methods: (1) When only a small number of aphids are present, a brush can be used to brush the aphids off, and the curled and withered leaves should be cut off; (2) Spray with a solution made by diluting 50% malathion emulsion to 100 times.
Ivy pest and disease control
1. Anthracnose
Symptoms: It often occurs during the autumn rainy season. When the disease occurs, gray-white lesions appear on the leaves, reddish-brown nearly round lesions appear on the cotyledons, and rust-colored small spots appear on the young stems, which later expand into short striped rust spots.
Control methods: (1) The concern with the onset of anthracnose is excessive humidity and insufficient ventilation, so watering should be stopped and the ivy moved to a ventilated and well-lit place; (2) Spray a 500-fold dilution of 50% carbendazim wettable powder.
2. Sunscald
Symptoms: The upper leaves and new leaves of ivy turn light gray, and gradually wither and fall early. The cause is generally moving ivy from a shady place into the sunlight, causing the ivy to be scorched by the burning sun.
Control methods: When cultivating, do not place ivy in a dark environment, and never move it directly from darkness into the sunlight for exposure. Usually it should be placed in a bright place for growing, and pay attention to the cultivation methods of ivy.
3. Phytophthora blight
Symptoms: Most of the leaves of ivy turn brown and rot, dark green water-soaked areas appear at the base of the stems and vines, and the diseased branches begin to wither. The cause is generally excessive humidity and a stuffy, hot environment, or soil carrying pathogens.
Control methods: (1) Pull out diseased leaves or diseased plants, and reduce the frequency and amount of watering; (2) Spray or irrigate with a 800-fold dilution of 25% metalaxyl wettable powder or a 600-fold dilution of 58% metalaxyl and mancozeb wettable powder; (3) During the plum rain season, drainage should be done in time, and attention should be paid to flood prevention work.
