1. Penicilliosis

Penicillium is a bacterial disease that erodes the leaves of lilies. Once infected, it will cause the leaves to grow some white spots, which will slowly grow larger and develop into patches, and finally the bacteria will invade the base plate of the bulb. Once there is no base plate, the bulb will lose its own value, causing the plant jihad to be slow, and the bacteria will spread to each other. We have to store the seeds at the lowest temperature. Those infected with germs must be soaked in an aqueous solution of carbendazim, chlorothalonil and carbendazim for more than half an hour, and then can be planted.

2. Rhizoctonia

The main infection of this pathogen is to harm the leaves in the soil, the leaves will appear light brown spots, if mild, it will only have a slight effect, but if the infection is very serious, it will affect the growth. Then the leaves of the underground part will rot and wilt. At this time, we should use soil disinfectants to disinfect the infected soil, and make sure that the disinfected soil can not be infected. Otherwise, it is tantamount to no disinfection.

3. Phytophthora

Phytophthora is a kind of bacteria that can make the plant wither suddenly, it will cause the plant to rot, and the stem will also have the phenomenon of soft rot, which will turn dark brown after decay, and then expand in all directions. we can use soil disinfectants to disinfect the soil first, and then use fungicides to control foot rot, the drainage of the soil should be good, and it is also necessary to prevent crops from being wet all the time after watering. The temperature of the soil should be kept to the lowest in summer to prevent high temperature from breeding germs.

4. Pythium

Pythium is a range of bacteria, it can damage not only a single plant, but also all plants in a range, the diseased plants will inhibit their development, resulting in short plants, yellowing leaves and dry flower buds. If you pull out the plants, you will see obvious light brown rot spots on the roots, which may have become completely soft and rotten. We should spray soil disinfectants to disinfect the soil.
