Cucumber cultivation in autumn is very easy to get bacterial leaf spot disease, cucumber leaves and melon strips can be victimized, severe reduction, early prevention and treatment.
Selection of disease-resistant varieties for agricultural control, such as Jinyan No.6, Xiaqing, black oil sticks, etc. Between 2 and 3 years of rotation with non-melon vegetables. Before seed sowing, soaking with warm water at 50°C for 20 minutes, or soaking with 40% formalin 150 times for 1.5 hours, or soaking with agricultural streptomycin 200ppm for 30 minutes, take out and allow germination after sowing. It is best to use sterile soil nutrition seedlings. Apply base fertilizer, increase phosphorus and potassium fertilizers, deepen the land, clean the countryside, and control the disease.
Chemical control can spray 72% of agricultural streptomycin 4000-5000 times, or neophytin 150-200ppm, or 77% can kill WP 400 times, or 50% DT fungicide 500 times, or A Shuangling Manganese Zinc WP 500 times, spray every 7 days or so, even spray 3 to 4 times.
According to the site of fungal infection,it can be divided into superficial fungal infection and deep fungal infection, superficial fungal infection is caused by ringworm infection of the skin, hair, fingers, toe fingers. The incidence rate is high with less harmful. Deep fungal infection is caused by Candida and cryptococcal invasion of internal organs and deep tissue, the incidence is low with big harmful. Classified based on mechanism action classification can be divided into (1) Antifungal agents for sterol synthesis in fungal cell membranes (2) Antifungal agents for fungal cell wall synthesis (3) Antifungal agents acting on nucleic acid synthesis, The Antifungal drugs easily affect the white blood cells and liver function, if in long-term use,it may caused a transient increase in GPT or leukopenia, withdrawal is normal.
