At present, affected by the continuous rainy weather, the groundwater level is high, the soil moisture in the shed is high, especially the bacterial diseases are high. For example, cucumber bacterial horn spot, tomato canker, eggplant soft rot, and so on.
Identify bacterial diseases
The pathogenesis of bacterial diseases is obvious, and the main manifestations are: necrosis and decay, wilting and deformity. Necrosis, decay and deformity are all the consequences of bacteria destroying the tissue of parenchyma cells.
On the leaves of its reticular veins, the lesions are polygonal with yellow halos around the lesions. Lesions on hypertrophic tissues or fruits, mostly round. In some cases, promoting lesions occur and tumors form after being killed, and this phenomenon mostly occurs on roots or stems. Bacterial diseases have no hyphae and spores, and there is no mold on the surface of the lesions, but there is bacterial pus (except for the root cancer bacteria) overflowing, and the surface of the lesions is smooth, which is the main basis for diagnosing bacterial diseases.
Timely prevention and treatment of pesticides
The agents for the prevention and treatment of bacterial diseases are mainly copper preparations and antibiotics, and it is recommended that when preventing and treating bacterial diseases, the two agents should be mixed, and the contact killing and systemic properties should be combined. The prevention and control agents include quinoline copper, copper oxide, Zhongshengmycin, etc., and it is recommended to take it step by step during the prevention and control.
Reduces the chance of wound infestation
The main infection of bacterial diseases is carried out from wounds, so in order to strengthen the prevention and control of bacterial diseases, attention should be paid to controlling the infection of wounds, one is to avoid pest bites, and the other is to avoid artificially caused wounds.
Pay attention to the insect-proof net set up at the vent of the shed and hang the sticky insect board in the shed, and use the medicine in time when the insect infestation is serious. Operations such as wiping buds, beating heads, removing branches, hanging vines, and picking fruits should be arranged in the morning on a sunny day, so that the wound can dry as soon as possible and avoid operation in the case of dew. When releasing the wind, it should also be avoided that the wind speed is too large, so that the vegetable branches and leaves will cause too many wounds due to swaying and friction. After the wound of vegetable plants, early spraying of copper preparations and streptomycin for prevention.
