What are the diseases and insect pests of Cymbidium? How to prevent and cure?

The common diseases of Cymbidium are blight, soft rot, root rot, anthracnose, leaf blight, soot, virus, etc.; insect pests are mainly shell insects, snails and so on.

(1) Prevention and treatment of epidemic disease. It can be sprayed with 80% Zn-mn Naipu 500 times solution. The diseased plants can also be sprayed with 2000-fold 8-hydroxyquinoline sulfate, or the diseased plants can be soaked in o-phenylphenol sodium solution for 1 hour and can be treated repeatedly within 3-7 days if necessary.

(2) Prevention and control of soft rot. To take preventive measures, the effect of spraying with 40% Kuadening 400x solution is good, or more than 68.8% chain microelement or 18.8% chain microelement 1000 times solution can be sprayed every 7 to 10 days for 3 to 4 times in a row. These drugs can be used alternately to prevent the plants from developing drug resistance.

(3) Prevention and control of root rot. Use 1 tablespoon of benzoate with 4 kg of water, soak or sprinkle the roots.

(4) Prevention and treatment of anthrax. Spray with Dafudan 500 times liquid or Dasheng-45 wettable powder 500 times liquid, or with mancozeb 1000 times liquid, once a week, 3 times in a row.

(5) Control of leaf blight. The method of prevention and treatment is the same as anthrax.

(6) Prevention and control of soot disease. In order to prevent soot disease, we must first control and eliminate the occurrence of aphids, whiteflies and shellfish. These insects do not exist and soot disease naturally does not exist.

(7) Prevention and treatment of viral diseases. At the current level, there is no treatment, once suspicious plants are found, they should be isolated or destroyed immediately.

(8) Prevention and control of insect pests. The scale insect parasites on the edge or back of the leaf to absorb sap, causing the plant to wither. In severe cases, the whole plant will wither and die, and coal fouling disease will be induced at the same time. Late May is the peak incubation period, and 40% omethoate emulsion 1000 times can be sprayed and killed. Snails can be killed manually or by bait such as snail killing.

Control of diseases and insect pests of Cymbidium grandiflora

Cymbidium because of large flowers, colorful and colorful, decorated in flower racks, balconies, windowsills and other indoor space, can create an elegant home living environment. Today, I would like to introduce the price of Cymbidium and the prevention and control of diseases and insect pests of Cymbidium.

Generally speaking, for high-quality Cymbidium with more than 4 arrows, the wholesale price of the base is expected to be 150-200 yuan per pot, 3-4 arrow mid-grade products 100-150 yuan per pot, and low-grade products less than 100 yuan. In addition, according to the growing period of Cymbidium, the price is different, the flower is the most expensive, the bud is the second, and the seedling is the cheapest. Of course, the price of Cymbidium is also different in each region. There are 3-4 flower branches in Beijing.

Control of Diseases and insect pests of Cymbidium

1. Fungal anthracnose

Mostly occurs at the top of the leaf, the spot edge is dark brown, the middle gray, mostly caused by high temperature, high humidity, poor ventilation, disease spot should be cut off in time, and cooperate with spraying. Common medicament has 1000 times mancozeb, 1000 times can be killed.

The following fungicides are commonly used to control other fungal diseases: 1000-fold chlorothalonil, 800-fold pyrethromycete, 800-fold metalaxyl.

2. Bacterial diseases

The commonly used agents are 6000-fold agricultural streptomycin sulfate, 300ppm agricultural streptomycin and 800x Jinggangmycin. During continuous cropping and long-term cultivation, soft rot will occur seriously. In the seedling stage, the disease will not occur, generally to the third year, when the flower bud reaches the height of 20 to 30 centimeters, it is found that the corms will suddenly rot, which will also occur in the mountains. At this time, it can only be destroyed, otherwise it is easy to spread the disease to healthy plants. If the surrounding environmental hygiene and drug control are carried out in time, the disease will be inhibited.

3. Insect pests

The main pests are slugs, spider mites, commonly used pesticides: slug nemesis (trapping), trichloroinsecticidal mites. When there is poor ventilation from June to September, slugs occur seriously, mostly hidden in the back of leaves, and harm the root system at the same time. Lime can be sprinkled in the cracks in bricks, and then water can be sprayed to kill a large number of adults. At the same time, longevity flowers and leaves and granule nemesis can be used to trap and kill. Leaf mites occur on the back of the leaves, so medication should start from the back of the leaves.

The above is for everyone to introduce the price of Cymbidium and Cymbidium pest control, hope to help you, more household knowledge, please pay attention.
