Rape is generally rape, which is widely planted in the world and widely planted in China, and is bred in multiple generations to be hybridized into multiple varieties which are suitable for different growth conditions and have different characteristics, and is mainly used as an oil crop.

In the rape planting process, various diseases and insect pests are easy to occur due to some pests, bacteria and the like, and the easily-occurring diseases mainly include sclerotinia, downy mildew, black rot and the like.

Sclerotinia rot of colza: the disease is mainly the pest stems, and also the leaves, flowers and pods. The disease spots on the stems are light brown initially, slightly concave and then turn grey-white, when the humidity is high, the disease parts become soft and rot, and white floccules (mycelium of bacteria) grow on the surfaces. The cortex rot, the medulla vanishes to form a cavity, large black sclerotium grows in the cavity, and sometimes sclerotium grows on the surface of the stem like mouse dung. The disease starts to occur in the flowering period of rape and is harmful until the mature period. Leading the plants to early wither, the seeds to be shrunken, and the yield and the harvest to be reduced.

Downy mildew of rape: the disease can occur in the whole growth period of rape, and causes leaf death and inflorescence fertilizer swelling deformity, and the disease can be harmful leaves, stems, flowers and pods. The symptoms are that the front surface of the damaged leaf is light yellow and unobvious disease spots which are polygonal, and white downy mildew grows on the back disease part of the leaf. The seeds cannot be firm or are poor in fruit setting, and the yield and quality of the rapeseeds are reduced.

Rape mosaic: the symptoms of rape mosaic disease are characterized by the occurrence of bright veins on young leaves after the disease, all or part of the veins being pale yellow (slightly transparent to light) followed by flowers She Zhengzhuang (i.e. yellow green versus dark green). Few leaves become malformed, plants are dwarfed, the fruits are fewer, and the number of loose grains is increased. The onset is heavy, and the whole plant is dwarf malformed. Water-spotted, brown to blackish-brown dead streaks tend to develop on the stems. The pod is bent, and heavy plants often die in early stages;
