Weather warmer recommended vegetable farmers control greenhouse disease
As the weather warms up, the greenhouse temperature at the shed is more suitable for the occurrence and expansion of vegetable diseases. In addition, the growth of pathogenic bacteria caused by the planting of sorghum has caused serious diseases such as tomato leaf mold, gray mold and cucumber target spot disease, and gray mold. The characteristics of the disease manifested as the rate of diseased sheds, the rate of diseased plants, the rate of diseased leaves, and the rate of disease-causing fruit rose rapidly, and the incidence was severe. Among them, the incidence rate of cucumber gray mold was higher. In view of the serious nature of the current disease, vegetable farmers should strengthen prevention and control, control the spread of momentum, and ensure fruit and vegetable harvest. Prevention: Agricultural control: 1. Remove diseased fruits in time, destroy them, and reduce proliferation. 2. The use of ground film cultivation, watering under the membrane, reducing the air humidity in the shed can effectively control the gray mold. 3. Renovate snoring timely and remove the old leaves from the bottom. 4.Smoothly clean the shed film, keep the shed film clean, increase the light transmittance, and improve the transparency of the shed. Chemical control: 1. Control gray mold can be sprayed with 70% pyrimethanil (Meican) water dispersible granules 1500 times, or 50% dofefamil (Widemilk) WP 500 times, or 50% iprodione suspension 1500 times, or 50% bocomycin water dispersible granules 2000 times. 2. In the early stage of disease prevention and control of cucumber target spot, 10% difenoconazole water dispersible granules 1500 times solution plus 80% carbendazim wettable powder 500 times solution spray, or 50% diflufenacetin ( Ricocon) Wettable powder 500 times spray. 3. To control tomato leaf mildew can be used 10% difenoconazole water dispersible granules 1500 times, or 50% more Fufumilweiwei (Reedy mildew) WP 500 times, or 2% samamycin water 400 times spray agent. The above-mentioned agents with different mechanisms should be used alternately, or drugs with different mechanisms should be mixed and used. According to weather changes, apply pesticides 5-7 days, three times in a row.
