Disease Control of Strawberry in Greenhouse
The pathogen of strawberry powdery mildew is single-shelled shell genera. With the help of airflow or rainwater, the optimal temperature is 25-30°C. The pathogenic bacteria can infect a variety of crops, and triadimefon pesticides have generally been resistant to them. Both fruit setting and late harvest are susceptible to disease. The key to open cultivation: the prevention period is the flowering period before flowering. Preventive medication: Baitai 1500 times or 25% to 100-gram 1000-1500 times, Longkei 500-600 times plus a new high-fat membrane spray to form a protective film to prevent the spread of bacteria through the rain, 7-10 days once. The prevention period of the small bow shed cultivation period was around December and around the second year of May. The early stage of disease prevention and prevention used drugs: 1000 times for Wuyiencin, 3000 times for Tsuibe, 50% for 1000-1500 times, 2000 times for Kaize. 500 times the standard mixture, Longke 500-600 times. Pay attention to the use of pharmaceuticals and do not use the same variety of pharmaceuticals more than 2 times. The pathogenic bacteria of Botrytis cinerea is most susceptible to disease when it is humid and the temperature is around 25°C. The incidence of fruit set and late harvest is the most serious. To prevent the main, the best period of application for the first strawberry inflorescence flowering more than 20% and the second inflorescence just flowering. Pharmacy selection: Kai Ze 1200 times or 1000 times or 50% Nongli Ling so 1000-1500 times, 500-600 times Longke bacteria, continuous control 2 times, alternating medication. When the disease is heavy, Kai Ze can choose 1200 times Baitai 1500 times or Kai Ze 1200 times, 50% make Bai gong 1000-1500 times, and Dragon bacillus 500-600 times.
