After identification and diagnosis, the author thinks that this is nodule cancer, and the seedlings should be treated before planting.

1. Soak the roots of suspicious seedlings with 1% copper sulfate solution for 5 minutes, rinse and plant.

2. The plant with root cancer is removed and the wound is smeared with 0.1% mercury solution before planting.

3. When planting, ferrous sulfate is used to mix the soil to change the acidity of the soil.

4. According to the law of its disease, mechanical damage can be avoided when grafting, planing and transporting seedlings, and the chance of invasion can be reduced by pathogens. When planting and breeding seedlings, they are not planted together or close to rose, peach, citrus and other flowers and trees, because the pathogen can infect these flowers and trees at the same time.
