1. Symptom recognition is mostly caused by adult stage, mainly affecting stems and leaves. Stem stalks occur, and many fusiform or elliptical lesions appear in the nodes, which gradually expand to several centimeters. The diseased part was grayish white, accompanied by a large amount of amber gum overflowing. After the diseased part was yellow-brown, the small black spots were scattered on it. Finally, the longitudinal part of the diseased part was chaotic, but the vascular bundle did not change brown, causing the stem to die. The incidence of the leaves is mostly caused by a semi-circular disease at the edge of the leaf, or a V-shaped extension from the edge of the leaf. The diseased part is large and the diameter can reach 20-30 mm.
Even bigger, occasionally up to half a blade. The lesions are light brown or yellowish brown, and faintly visible rounded lines are visible, with many small black spots scattered on them. In the later stage, the lesions often rupture, and the fruits of seriously ill plants can sometimes be affected. The melon strips are mostly infected in the flowering stage of the young melons. The umbilical part of the diseased melons is fine. After the longitudinal sectioning, the upper flesh is light brown and softened to be heart-shaped.
2 The pathogen Ascochytacitrullina Smith said that the genus Diospora is a subfamily fungus, and the small black spots on the leaf lesions are mostly conidia of the pathogen. The conidia are buried under the epidermis, and then the pores are exposed, spherical or oblate, dark brown, endogenously many conidia, short round or cylindrical, colorless, initial unit cells, and later become twins. The small black spots on the stems are sometimes the bacterium capsules. The ascospore shell is spherical, black, and many endogenous straight or curved colorless and transparent rod-shaped ascus. There are 8 ascospores in the ascus, and the ascospores are colorless and twin.
In addition to infecting cucumbers, the bacteria also infect various melon crops such as watermelon, melon and loofah.
3. The pathogens of the disease are overwintered in the soil by conidia or ascospores with the diseased body, or by conidia attached to the surface of the seed or adhering to the frame and the shed skeleton for wintering. When the seed is germinated after sowing, the seedlings infect the seedlings to cause onset of the cotyledons. Pathogens in diseased soils in the soil directly infect the field plants in the following year. After the onset of the field, the conidia produced by the disease department are spread by wind and rain, irrigation water and farming operations, and the seeds can be transported long distance with the seeds. After the spores germinate, they can invade from the pores, water holes or wounds.
The pathogens are warm and wet. 20-25 ° C, relative humidity of 85% or more, soil moisture is prone to disease. The melons are heavy, the plants are too dense, the ventilation is poor, the growth is weak, etc., and the disease is developing rapidly.
Prevention and control of cucumber blight
Cucumber blight has occurred in various places of protection and is becoming more and more serious.
