Growing Methods and Key Technical Points for Bean Sprouts (Pea Shoots)
First work the plot into a fine tilth, apply base fertilizer, then level it into flat beds, and sow the treated seeds directly with a covering of soil. After the seedlings emerge, top-dress and water promptly to keep the plot moist. Once the bean sprouts have 2 true leaves, promptly apply a quick-acting nitrogen fertilizer, along with fertilizers such as potassium dihydrogen phosphate.

What fungicide works well to control Sclerotinia rot
For Sclerotinia rot, generally apply 4-5 kg of 50% carbendazim wettable powder per mu, mix thoroughly with an appropriate amount of dry soil and spread it on the bed surface, then rake it into the soil, which can reduce the primary infection source. At the early flowering stage, you can use a 500-fold dilution of 70% mancozeb wettable powder; a 1000-fold dilution of 70% thiophanate-methyl, 50% carbendazim or 40% validamycin wettable powder to spray the stem base, old leaves and ground surface of the plants; start applying the fungicide at the early stage of disease onset, once every 7-10 days, and 2-3 consecutive sprays can achieve effective control. <p style="text-align:center"></p> <p style="text-indent:2em;"><span style="color:#FF0000"><strong>1. What symptoms does Sclerotinia rot have?</strong></span></p> <p style="text-indent:2em;">At the seedling stage, red-brown spots appear on the affected stems and leaf stalks, and later they expand and turn white. If the disease occurs at the leaf stage, the leaf margins of the old leaves at the base of the plant are the first to be affected.</p> <p style="text-indent:2em;">The lesions initially appear dark blue-green and water-soaked, and later expand into round or irregular large spots. The center of the lesion is yellow-brown, and the surrounding area is light yellow. Sometimes the outline pattern on the lesion is relatively obvious. In dry weather, the lesion will crack and perforate; in rainy weather, the lesion will expand rapidly and the whole leaf will become rotten.</p> <p style="text-indent:2em;">If the disease occurs on the stem, the pathogen generally appears on the middle and lower parts of the main stem. The lesion initially appears light brown and water-soaked, and later gradually develops into an oval shape. Under humid conditions, the lesion expands rapidly. In the late stage of disease development, the cortex splits longitudinally, and the root stem becomes extremely easy to break.</p> <p style="text-indent:2em;"><span style="color:#FF0000"><strong>2. What is the disease pattern of Sclerotinia rot?</strong></span></p> <p style="text-indent:2em;">The pathogen of Sclerotinia rot is Sclerotinia sclerotiorum. The sclerotia are round or irregular in shape, white at first and black later, and the interior of the pathogen is grayish white. The pathogen has a very wide host range. Besides rapeseed, it also affects many other crops such as sunflower and carrot.</p> <p style="text-indent:2em;"><span style="color:#FF0000"><strong>3. How to control Sclerotinia rot?</strong></span></p> <p style="text-indent:2em;">1. Agricultural control:</p> <p style="text-indent:2em;">(1) Develop disease-resistant varieties: cultivate high-yield, disease-resistant improved varieties according to local conditions.</p> <p style="text-indent:2em;">(2) Seed disinfection: through screening, chemical seed soaking and other methods, eliminate sclerotia and kill bacteria on the seed surface, and sow disease-free seeds.</p> <p style="text-indent:2em;">(3) Timely remove diseased residues: after harvesting the crop, promptly burn and clear the diseased residues in the field and beside the roads to reduce the source of the pathogen.</p> <p style="text-indent:2em;">2. Chemical control:</p> <p style="text-indent:2em;">Use special-effect fungicides such as prochloraz and Shibaike for protective treatment. The best application period for prochloraz is from the full flowering stage to the late full flowering stage.</p> <p style="text-indent:2em;">The above is a detailed introduction to what fungicide to use for Sclerotinia rot and its disease symptoms. I hope it is helpful to everyone.</p>

What fungicide works well to control early blight in tomatoes?
Early blight in tomatoes is a constant worry for growers. So if a tomato plant gets early blight, what fungicide should be sprayed and how should it be controlled? Early blight in tomatoes occurs in northeast China, north China, east China, southwest China and other regions; the most important feature is that whether the disease spots appear on fruit, leaves or the main stem, they all have obvious concentric rings, so it is also called ring spot disease. Fruit spots are mainly near the fruit stalk, stem spots are often at the branching points, and leaf spots occur on the leaf mesophyll. A few key points are summarized below, let's take a look. <p style="text-align: center;"></p> <p style="text-indent:2em;"><span style="color:#FF8C00">1. Symptoms of early blight</span></p> <p style="text-indent:2em;">Tomato early blight mainly harms leaves, but can also harm seedlings, stems and fruit. When seedlings are infected, dark brown spots appear at the base of the stem, slightly sunken with concentric rings. When leaves of mature plants are damaged, it mostly develops from the lower leaves upward. It first appears as water-soaked dark green spots, which after expanding become round or irregular ring-patterned spots. The edges often have a light green or yellow halo, and the center shows concentric rings. When humid, black mold grows on the spots, and in severe cases the leaves fall off.</p> <p style="text-indent:2em;"><span style="color:#FF8C00">2. Occurrence pattern of early blight</span></p> <p style="text-indent:2em;">Tomato early blight is caused by infection by Alternaria solani. The pathogen can overwinter in soil or on seeds, spreads through wind and rain, and invades through stomata, lenticels, wounds or the epidermis, causing disease. The pathogen can infect repeatedly in the field, and the disease is severe during the peak fruiting period. When the temperature is 20 degrees, relative humidity is above 80 percent, or in rainy weather, the disease tends to become epidemic. Continuous cropping land, low-lying land, excessive watering or poorly ventilated plots suffer severe disease.</p> <p style="text-align: center;"></p> <p style="text-indent:2em;"><span style="color:#FF8C00">3. Control of early blight</span></p> <p style="text-indent:2em;"><span style="color:#008080">1. Chemical control of early blight</span></p> <p style="text-indent:2em;">In the early stage of disease, promptly remove diseased leaves, diseased fruit and severely diseased branches, and begin spraying fungicides. To prevent resistance and improve prevention, it is recommended to rotate, alternate or use mixed formulations, spraying once a week for three consecutive sprays. When the disease is severe, remove the central diseased plants and diseased leaves, and promptly adopt a control method combining Chinese and Western approaches.</p> <p style="text-indent:2em;"><span style="color:#008080">2. Agricultural control of early blight</span></p> <p style="text-indent:2em;">(1) Grow strong seedlings: adjust the temperature and humidity of the seedbed well, and separate the seedlings when they reach the two-leaf-one-heart stage, being careful to prevent the seedlings from becoming leggy. This can prevent disease during the seedling stage.</p> <p style="text-indent:2em;">(2) Crop rotation: tomatoes should be grown in a three-year rotation with non-solanaceous crops. Strengthen management: adopt high-ridge cultivation, fertilize reasonably, and after transplanting and seedling recovery, close the rows promptly to promote the growth of new roots. In greenhouses, control temperature and humidity well, and strengthen ventilation management.</p> <p style="text-align: center;"></p> <p style="text-indent:2em;">The above is what the Tuliu.com editor has brought you about what fungicide to spray for tomato early blight. We hope it is helpful to farmers. If you have any questions, you can leave a comment below, and I will reply to everyone promptly. See you next time.</p> <p style="text-indent:2em;"> </p>
