The Latest Methods for Preventing and Controlling Pests and Diseases of Aconite

Aconite, also known as caowu, salt aconite, and eerhua, is the “number one traditional Chinese medicine for restoring yang and rescuing from collapse”, with the effects of restoring yang and rescuing from collapse, supplementing fire and assisting yang, and dispelling cold and relieving pain. In the process of growing aconite, pests and diseases are one of the main reasons affecting its yield and quality, so how should aconite pests and diseases be prevented and controlled? Let's take a look together.

1. Southern blight

This disease is the main disease of aconite, generally occurring in the high-temperature seasons of summer and autumn. After onset, the tuberous roots begin to rot, and the leaves gradually change from the bottom upward, and finally most of the tubers rot, the leaves wither and fall off, and the whole plant dies. On the rhizomes on the ground surface, white silky mycelium and brown sclerotia can also be seen.

Prevention and control methods: Reasonably rotate with rice or wheat crops, do a good job of disinfection when preparing the land, promptly dig out and take diseased plants out of the field to burn when found, and spread lime powder on the diseased holes for disinfection. At the same time, spray carbendazim on the surrounding plants to prevent the disease from spreading.

2. Downy mildew

It is one of the main diseases of aconite during the seedling stage when planting, with a relatively high incidence rate and relatively serious condition, and it is extremely prone to occur during rainy and cold wave periods. When the disease occurs, the leaf edges curl backward, the leaf color turns grayish white, and a light purple mold layer appears on the back of the leaves, which is the pathogen.

Prevention and control methods: When the disease occurs at the seedling stage, thoroughly pull out the diseased seedlings, then spray Bordeaux mixture on the leaf surfaces and backs of the surrounding seedlings to prevent the disease from spreading.

3. Powdery mildew

It generally occurs from June to September. When the disease occurs, it starts from the leaves on the lower half of the plant and gradually spreads upward. A layer of white powdery substance is produced on the stems and leaves, and the leaves begin to gradually twist and slowly die.

Prevention and control methods: Strengthen fertilizer management to enhance the disease resistance of the plants, pay attention to soil moisture, drain promptly after the rainy season, and spray triadimefon when the disease occurs, which has a relatively good effect.

4. Aphids

Aphids harm plants as adults and larvae. They generally begin to appear from March to April, and May to June is the peak period of infestation. They gather on the leaves and gnaw the tender stems at the top of the plant, eating the young and tender parts of the plant clean in a short time, causing the plant to be unable to grow normally.

Prevention and control methods: When pest damage occurs, spray with 40% dimethoate emulsifiable concentrate diluted 800-1500 times.
