How to deal with insects in the mud of water lilies, and what to do if there are insects in water li

Water lily insect diseases: 1. Aphids.

During the growth and development period, if the water lily is not lit enough and the ventilation is poor, it will not only grow weakly, but also be vulnerable to aphids.

Solution: When insect pests are found, they can be sprayed with dichlorvos 1200 times aqueous solution, or killed with tobacco leaf water (50 grams of tobacco leaves add 5 kg of water and boil).

Water lily insect diseases: 2. Water borer.

The water borer mainly feeds on the leaves of plants with larvae, and when the damage is serious, it often eats up the mesophyll, leaving reticular leaf veins, and feeds mostly at night.

Solution: If the larval protection whip floating on the water surface is found, it should be fished with a net in time and sprayed with 50% 1000 times of pine borer.

Water lily insect diseases: 3. Black spot disease.

Black spot disease mainly affects the leaves of water lilies, with yellowish patches on the leaves at the beginning of the disease, and round or irregular shape in the later stage, turning brown and with wheel lines, sometimes with yellow-green halos on the edges, and a black mold layer with a diameter of 5 to 15 mm. In severe cases, the lesions are connected into patches, and the whole leaf is yellowish except for the leaf veins. The disease is caused by fungi and is severe in the rainy season, when lotus ponds or potted plants are cropped, and when nitrogen fertilizer is applied too much or the water temperature is too high in summer.

Solution: Strengthen cultivation management and remove diseased leaves in time. Plants with more serious disease need to be replaced with new soil and replanted, and nitrogen fertilizer should not be applied. At the onset of the disease, 75% chlorothalonil 600 800 times solution can be sprayed for prevention and control.

Water lily insect diseases: 4. Brown spot disease.

Brown spot disease mainly affects the leaves of water lily flowers, with round spots of millimeter diameter appearing on the diseased leaves, which are light brown to yellowish brown with dark edges. In the later stage of the disease, many small black mold spots grow on the lesions. The disease is more severe in autumn when it rains. The germs mostly overwinter on the carcass.

Prevention and control methods: remove residual leaves and reduce the source of disease. If the disease is severe, 50% carbendazim 500 times solution or 80% zeb 500 800 times solution can be sprayed for prevention and control.

Are there mosquito larvae in water lily pots? In this way, it can effectively kill insects and does not pollute the water quality.

Water lilies grow insects, need to be sprayed on the plant with special drugs in time, so as to completely kill pests and diseases, if you want to prevent it from growing insects, then when maintaining water lilies, you should change the water regularly, and let it have sufficient light every day, and in summer, you need to do a good job of ventilation measures for water lilies.

1. Drugs**

If the water lily grows insects, it will cause the plant to not grow healthily, at this time we need to use drugs according to the type of insects, dilute the insecticide and water in a certain proportion, and spray it on the water lily, so that it can completely kill the pests.

2. Clean water quality

Water lily is an aquatic plant, if the water quality is not clean, it is easy to grow insects, so if you want to prevent it, then we need to regularly replace the water lily with new water to ensure that the water quality is clean and clean, pay attention to the use of tap water for maintenance, then you need to stand for two days, and wait for the chlorine to volatilize before use.

3. Sufficient light

Water lilies like sunlight, if they are maintained in a dark environment for a long time, water lilies will grow poorly, which is also easy to breed insect pests, so when maintaining water lilies, they need to be placed in a sunny place, so as to facilitate photosynthesis of water lilies, and the probability of insect pests will be reduced a lot.

4. Ventilation environment

If the ventilation is poor, the water lily is also easy to breed pests, so when we maintain the water lily, we also need to do a good job of ventilation measures, especially in summer, it is best to maintain it in a cool and ventilated place, and we must avoid the plant in a stuffy environment, so that the water lily can grow healthily.

Hello, dear, water lilies will have small insects, water lily water borer. The water borer, also known as the cotton water borer, damages the leaves of water lilies with larvae, bites the leaves into two pieces of the same size, and then spins the leaves to overlap them together to make a protective sheath and lives in it. For example, with the help of the maintenance of leaves, Li Li can float freely on the water surface.

After protecting the sheath, a new sheath was created. The larvae are more slag searched, disturbing pure activity at night to feed. From August to September, the larvae mature and often close the two leaves, and then spin the silk to form a white oval cocoon flower pupa.

Prevention and control methods: Catch the larvae floating on the surface of the water with nets in time. During the larval occurrence period, it can be sprayed with 50% pine borer 1000 times.

<>1. If we find that the water lilies raised at home have nematodes, we can raise a few fish in the water, but the species of fish should raise tropical fish, because the water lilies like sunlight and need full sunshine, so the water temperature is relatively high, and if you raise cold-water fish such as koi, koi will die because the water temperature is too high. It is recommended to raise guppies and other species, and the ornamental value is relatively high.

2. Oleander is a shrub plant, and the whole plant is highly toxic, so we can take oleander to kill nematodes, but it should be noted that it should not be eaten by mistake, and it is necessary to wear gloves when mashing oleander to avoid poisoning, and it should be absorbed after completion, and the utensils should be properly disposed of to avoid poisoning by others.

3. We can spray pyrethroid insecticides into the water, this kind of insecticides will decompose quickly, so it will not affect the growth of water lilies, we should remember to dilute when spraying insecticides, so as not to ablate the roots of water lilies, and at the same time take protective measures, such as wearing masks and so on.

4. This is the most convenient way to kill nematodes, because ginger and garlic are common items at home, we can mash ginger and garlic, then wrap it in gauze, and put it in water for about an hour to kill nematodes.
