Asparagus stem blight control method

Because of its rich nutritional value and health care function, asparagus has become a popular vegetable for people to eat in recent years. At present, the asparagus planting area in our province is also expanding year by year. Asparagus stem blight is one of the major diseases in the production of asparagus. Stem blight mainly affects the tender stems and lateral branches of asparagus. In the early stage of the disease, firstly, water-stained pale cyan spots appeared on the main stem near the ground. As the disease progressed, the lesions gradually expanded, and the color of the lesions gradually turned grayish brown or white. The margin of the lesion is sometimes white fluffy, with black spots on the lesion. When the disease is severe, the stems are hollow and easily broken, and the upper leaves and leaves die. In order to enable asparagus to grow robustly, the control methods for stem blight of asparagus are briefly described as follows:

1. Selection of Disease-Resistant Varieties Since the disease resistance of stem blight is different among different asparagus varieties, it is possible to select the disease-resistant or disease-resistant strains of Asparagus officinalis No. 1, No. 2, or Jinglualu No. 1 according to local conditions. Variety.

2. Do a good job in field management, including close planting to prevent excessive density, rational fertilization, organic fertilizer application, nitrogen fertilizer control, reasonable irrigation, water pouring, prevention of flood irrigation, and timely drainage after rain. Create a well-ventilated and light-growth environment for asparagus.

3. Do a good job of removing diseased plants and old stems in time during the growth of asparagus in the field. In the early winter, when the asparagus stems in the field are withered, the diseased plants are removed and the surface debris are removed. In this way, both the source of bacteria in the field and the ventilation and light transmission between plants can be reduced.

4. In the early stage of onset of disease control, 50% carbendazim wettable powder 600 times, 75% chlorothalonil wettable powder 600 times, or 70% thiophanate-methyl wettable powder 800 times can be used. Or 80% mancozeb WP 800 times, or 40% myclobutanil wettable powder 2000 times, or 10% difenoconazole water dispersible granules 1500 times spray control. Generally every 7 to 10 days 1 times, continuous alternate, rotation control 3 to 4 times. Http://Content/7383be3d-9a69-4f15-baa6-d4ba5c422c52?cType=2
