Compared with insect pests, this plant has many "diseases". Here, we will introduce various diseases in detail. The first disease is called Sclerotinia sclerotiorum. To treat this disease, we must first disinfect the soil. Then, we have to spray the sclerotia cleaning agent one thousand times, and then spray it again ten days later, which is probably the third time around beginning of spring. There is also the need to pay attention to environmental control, such as strengthening ventilation and so on, which has a good effect on reducing diseases.

The second is "leaf blight", which can also be seen from its name. Once the disease occurs, it spreads very fast, so it is also very harmful. After infection, the leaves will turn yellow-brown, and once the temperature is too high, it will cause large-scale decay. To deal with this disease, carbendazim can be used 600 to 800 times to prevent and treat it. There is also strengthening management, such as paying attention to ventilation and controlling the amount of watering. But in order to reduce the occurrence of this disease from the source, we can sterilize the seeds when sowing.

The third kind is "root rot", which threatens its roots, making it yellow-brown, soft and rotten, and even broken when pulled out. This disease often occurred in June+10 in 5438, that is, in late autumn. To prevent and treat this disease, you can also choose carbendazim spray, and you must pay attention to controlling humidity, and the amount of watering must not be too much.
