Spider mites, such as pouring soil can be prevented.

Nematodes in the soil.

2. Laundry detergent.

15 grams, 15 ml of 20% caustic soda, kilogram of water, mix the three and spray well, check a day or two later, red spider.

The mortality rate of full-fledged and full-fledged mites is 94%-98%.

3. Take 50 grams of plant ash.

Add 2500 grams of water and stir thoroughly, soak for two days and nights to filter, add 3 grams of laundry detergent to adjust evenly and spray daily.

Once, for three consecutive days, and then sprayed for three days every other week, it can eliminate the second generation of pests, and can also control aphids, red spiders, and scale insects.

Wait. Stinging and sucking pests. Put it in the taxi to control maggots.

The body of the spider mite is the size of a pinpoint, deep red or purplish-red, and only small red dots are visible to the naked eye, under a magnifying glass.

Under the ability to see oranges.

Red, transparent, globular eggs. Its nymphs often congregate on the dorsal and bud of some flowers, sucking the juice with their stinging mouthparts.

Damage to plants. The initial symptoms of flowers are leaf loss of green, leaf edge upturning, so that wilting, falling off, resulting in early atrophy of flower buds, and in severe cases, plants. Death.

You look closely at the webs and leaves to see if there are small red spiders the size of pinpoints, and if there are, there are red spiders, which suck the sap of plants on the young leaves and spin silk webs, causing poor plant growth. Acaricides such as avermectin can be used and sprayed after dilution according to the multiples required by the packaging.

Insect pests can be sprayed with 40% dimethoate 1000 times liquid, leaf blight is easy to occur when the humidity is too large and the ventilation is poor, the air humidity should be appropriately reduced and attention to ventilation and light transmission. After the onset of the disease, spray 200 times of Bordeaux liquid, or 500-600 times of 50% carbendazim wettable powder for prevention and control.

Bamboo is a small plant with high ornamental value, mainly potted leaves, light body, chic, elegant and quiet, it is a favorite foliage flower, especially in the study, desk, bedroom, living room to place a pot of cinnabar potted bamboo;

Slender as a feather leaf, if it meets flowers, although the flowers are small and white, but the stars are dotted, in the emerald green bushes, it looks elegant and lovely, and its fragrance is very strong.

Place the bamboo in a ventilated and transparent place, cut off the diseased part, and the plant will gradually improve without medication.

It's very simple, you can use the tobacco from cigarettes to soak in water, and use it directly to spray pests after 24 hours, or you can go to the flower and bird market to buy professional pesticide powder, there are many types, and it is easy to use.

Hey, according to the Chinese theory of curing diseases and curing the roots, I suggest that you go directly to Wenzhu's

Bamboos are usually less susceptible to spider mites, and can also be infected when nearby flower spider mites breed in large numbers. Here's how to judge:

Spider mites are millimeters long, pear-shaped, and generally red; The larvae mites are nearly round, the overwintering generation of young mites is red, and the non-overwintering generation of young mites are yellow. When such a small insect appears on the bamboo, it can be suspected to be a red spider. Spider mites form loose silk webs on plants and move between them.

The way of red spider damage is to suck the juice into the leaves with their mouthparts, so that the chlorophyll is destroyed, and the leaves appear gray and yellow spots or patches, and the leaves are orange, fall off, and even lose light. Therefore, if the leafy branches of the bamboo turn yellow and fall off, and there are the conditions described in the above two items, it can be determined that it is a red spider.

The slightly yellowing leaves of Wenzhu should not be a red spider, I have raised Wenzhu for many years and have not seen a red spider, but I dare not conclude that he will not grow, but other flowers in my family have red spiders but have not been infected. Wenzhu has strict requirements for water, and if you water too much, it will rot the roots, causing the plant to die, and if you water less, it will dry up, so it is not very easy to control, but he is also a very good flower. When watering, you should see wet and dry, rather dry than wet, dry air will also be yellow and dry, you can spray some water to increase humidity, because the air is too dry in this season, keep the air moist, not the potting soil moist.

It's okay to cut off the dry ones. According to your description, there shouldn't be a big problem!

(1) How to judge the length of bamboo.

Spider mite. One: See if there are spider webs on the leaves, if there is spider web-like spider silk, it means that Wenzhu has red spiders.

Two: see if there are red dots on the leaves, about a millimeter of size red dots, move it will move, if there are and the number will be more, this is the most important to identify whether there are red spiders.

Three: The damaged leaves have small yellow spots, and in severe cases, the leaves look like fire-grilled leaves.

2) Chemical control should be applied to 4000-5000 times of mite danger (800-1000 pounds of water per bottle of 100 ml) uniform spray, 40% dicofol EC 1000 1500 times, 20% mite kill net wettable powder 2000 times, 15% pyridoxine EC 2000 times, 1 8% zitogenol EC 6000 8000 times, etc.

If it is the spider, you will see that the leaves of the plant are wrapped in a layer of white web, my bamboo has grown red spiders before, the leaves are all white webs, and the leaves begin to wither yellow after a period of time, but it is good to spray it with laundry detergent water, and now it is growing very well, and I thought I couldn't feed it before.

Bamboos are a common potted plant, and in the process of maintenance, there will be some preparation problems, such as yellowing of leaves, cobwebs, etc. If not treated in time, it will affect the growth and ornamental value of the plant.

First of all, the yellowing of the leaves can be caused by improper watering, too wet or too dry soil. The amount of watering should be increased or decreased appropriately according to the actual situation, and the reaction of the plant should be observed and adjusted in time. At the same time, it can also fertilize bamboos to provide sufficient nutrients and promote the healthy growth of plants.

Secondly, the growth of spider webs is usually caused by the infestation of spider mitomies. Plants can be sprayed with specialist insecticides, or biological methods such as placing spiders parasitic on lizards near bamboo, using the lizard's predatory abilities to eliminate spiders. However, it is important to note that you should pay attention to safety when using pesticides and protect yourself and the surrounding environment.

In short, for the yellowing of leaves and the growth of spider webs, we can effectively treat and prevent them through scientific methods to ensure the growth and beauty of bamboo.

Bamboo long spider webs spray leaves or should choose different methods to control. For the case where the bamboo plant is covered with cobwebs, spider web medicine is an effective option. However, if there are only slight young leaves on the leaves, it is not enough to spray directly with a spider web drug, because the drug may cause harm to the plant, so other feasible methods need to be considered.

For the situation where the bamboo is covered with spider webs, spider web medicine is an effective control tool. Insecticides such as organophosphates, carbamate and pyrethroids in spider web medicine can effectively kill spiders on bamboos and their webs. The use of spider web medicine is more common on indoor bamboo, as fewer cobwebs form indoors.

However, for bamboos with only slightly young leaves, the use of cobwebs is not the best choice because the medicine may cause damage to the plant. In this case, the manual removal method can be used. Wipe off the young leaves, and if necessary, try adding detergent to the water to thoroughly clean the cobwebs from the young leaves.

In addition, a high-pressure water gun can be used to clean the cobwebs on the stems and petioles. This effectively controls the spread of spiders.

In short, for the cobwebs on bamboo plants, different control methods need to be selected according to the actual situation. Spider web medicine is a powerful way to control the overgrowth of spider webs in bamboo, but in the case of slight young leaves, manual removal is required to ensure the normal and healthy growth of the plant. The ultimate goal is to reduce the harm of spiders to bamboos as much as possible and protect the healthy growth of bamboo.
