Corn seedling blight, also known as root rot, is a fungal disease caused by Fusarium oxysporum in maize seedlings. In recent years, the occurrence of corn seed blight has increased and gradually increased, seriously affecting corn yield. The terrain is low, the soil is poor, the clay or saline-alkali land is seriously affected, and the sowing is too deep and easy to occur. In addition, improper fertilization leads to soil phosphorus deficiency, which is also beneficial to the infection of corn seed blight. In the early stage of the disease, the heart of the corn seedlings is often curled and wilted, and in severe cases, the dead seedlings are caused. In production, the main prevention methods for the disease are: 1. Choose high-quality, disease-resistant varieties. Before sowing, use 2.5% chlorfenapyr suspension coating agent 10 g water 100 ml, mix 5 kg, or soak for 40 minutes with 40% ketomycin 600 times or 70% thiophanate 500 times, dry Sowing after. 2. Reasonable rotation, formula fertilization, and strengthen field management. Reduce the amount of nitrogen fertilizer application, increase the application of organic fertilizer, pay special attention to the application of phosphorus and potassium fertilizer to promote root growth, cultivate strong seedlings, and improve plant disease resistance. 3. Chemical control. In the early stage of the onset of maize seedling blight, the base was sprayed with 70% thiophanate 800 times solution, 20% triadimefon 1000 times solution or carbendazim 3000 times solution, and sprayed twice. 4 Wire Video Intercom System,Analog 4 Wire Intercom System,4 Wire Video Doorbells,Doorbell System For Villa,4 Wire Intercom System Zhuhai Mingke Electronics Technology Co., Ltd , https://www.mingke-tech.com
