Aconite alias Aconitum, salt aconitum and goose flower is the first product in traditional Chinese medicine, which has the effect of returning yang to save adversity, replenishing fire and aiding yang, dispelling cold and relieving pain. In the process of planting aconite, diseases and insect pests are one of the main reasons that affect its yield and quality, so how to control the diseases and insect pests? Let's take a look.

1. White silk disease

The main disease of aconite in this disease usually occurs in the high temperature season in summer and autumn. after the disease, the root begins to rot, the leaves begin to change gradually from the bottom up, and finally most of the tubers rot, the leaves wither and fall off, and the whole plant dies. White filamentous hyphae and brown sclerotia can also be seen on the rhizome of the ground.

Control methods: reasonable rotation with rice or wheat crops, do a good job of disinfection during soil preparation, dig out diseased plants and burn them out of the field in time, disinfect the disease holes with lime powder, and spray carbendazim on the surrounding plants at the same time to avoid the spread of the disease.

2. Downy mildew

It is one of the main diseases of aconite in the seedling stage when it is planted. The incidence is high and the disease is more serious. It is easy to occur during the cold wave of overcast and rain. When the disease occurs, the edge of the leaf is reversed, the leaf color becomes grayish white, and a lilac mildew layer appears on the back of the leaf, which is the pathogen.

Prevention and treatment: when the disease occurs in the seedling stage, the diseased seedlings should be removed thoroughly, and then the leaves and backs of the surrounding seedlings should be sprayed with Bordeaux liquid to avoid the spread of the disease.

3. Powdery mildew

It usually occurs from June to September, when the disease occurs, the lower half of the leaves of the insect plants begin to spread upward, and a layer of white powder will be produced on the stems and leaves, and the leaves begin to twist gradually and die slowly.

Control methods: strengthen fertilizer management, enhance plant disease resistance, pay attention to soil moisture, timely drainage after the rainy season, when the disease is sprayed, the effect is better.

4. Aphids

Aphids are harmful to adults and larvae, and generally begin to attack from March to April. During the peak period of the pest disaster, aphids will gather in the leaves, nibble on the tender stems at the top of the plant, and clean up the young parts of the plant in a short time, resulting in the normal growth of the plant.

Control method: when the pest occurs, it can be sprayed with 80-1500 times of 40% dimethoate EC.
