Tomato early blight mainly affects the leaves, stems, flowers and fruits of tomato. The typical symptoms are black rounded concentric plaques. The disease is overwintered by hyphae or conidia on sick bodies or seeds, from stomata, The lenticels or epidermis invade directly, forming primary spores, and repeated infestation by airflow and rain. Promptly carry out pesticide control and reduce losses.
At present, the winter and spring tomatoes enter vigorous growth and the fruit is rapidly expanding. The leaves of the base begin to age. The average temperature in the first ten days before May 8 is 20 °C, and the relative humidity of the greenhouse is longer than 70%. The popularity is very beneficial. According to the investigation of the Yongnian County Plant Protection Station, the disease rate has doubled from April 26 to May 8, and the diseased leaf rate has increased tenfold. In the old shed area, tomato continuous cropping area and transplanting In the early areas, the incidence was heavier, the rate of disease was 100%, the rate of diseased plants was 100%, and the rate of diseased leaves was 54.2%. Vegetable farmers should pay close attention to the investigation and control the spread of momentum.
Control method:
1. Strengthen cultivation management. Remove the early diseased leaves in time; pay attention to ventilation, reduce the humidity in the shed; increase the application of phosphorus and potassium fertilizers to improve the disease resistance of the plants.
2. Chemical control.
(1) For the non-onset or mild-onset field, an induced immune disease prevention method may be adopted, that is, an immunomodulatory fungicide having an induction, such as a 25% azoxystrobin suspoemulsion (Amishida) 1500 times solution, 0.5% amino oligosaccharide may be selected. 600 times of the water agent, 0.136% of the protection of 15,000 times of liquid, etc., in the early stage of tomato growth alternately used 2 to 3 times, can effectively control the development of early blight.
(2) China Pesticide Network recommends that the affected field should use 10% difenoconazole water dispersible granules 1500 times solution or 25% propiconazole emulsifiable concentrate 3000~3750 times solution or 21% peracetic acid 300 times solution or 6.5% bacteria Qing (an rot) 300 times liquid spray control.
