At present, it is the heading stage of rice, and it is also the rice disease prone period. It is predicted that this year rice blast disease, sheath rot disease, and bacterial brown spot disease have occurred more than in the same period of the calendar year. Under different species and different management levels, the degree of disease is also different. Since the beginning of this year, since July, the high temperature, humidity, and rain have made rice flourish and the population has closed. This is the main reason for the occurrence of rice diseases. If we do not strengthen prevention and control, pathogens can rapidly spread and provide adequate sources of bacteria for the occurrence of panicle blasts. Please ensure that the majority of rice farmers are fully aware of the seriousness of rice diseases and timely implement preventive and control measures to overcome the paralysis and luck. Ensure safe production. Specific measures include:
The first is to strengthen drug control. 1. Prevention of fungal diseases: rice blast, sheath rot, bacterial brown spot, and sheath blight preventive measures: Use propiconazole to make 100 grams or Fuji No. 1 (Inabasin) plus polymycin, etc. Use according to the instructions. 2. Bacterial diseases in rice include bacterial brown spot, bacterial base rot, and bacterial blight. 3.Measures for controlling fungal and bacterial diseases: 700 g per hectare of sterilized (chlorobromohydrin uric acid) or 800 g of rice disease Rickettsia + 320 ml of bacillus catarrhalis, spraying 300 kg of water Shi, the occurrence of severe plots was sprayed once every 7-10 days.
The second is to strengthen field management. 1. Water management: There should be a saturated water condition in the overly prosperous plots. The normal state should be shallow water irrigation, which is conducive to the down-rooting of rice roots, absorption of nutrients, and at the same time it can play a role in lodging resistance. 2. Controlled regulation: In the full heading stage or milk ripening stage, combined with disease prevention, 30 tons of potassium per potassium dihydrogen phosphate (30 g per ton) can be sprayed, which can increase the vascular bundle cell wall thickness and enhance the lodging resistance. At the same time, It can increase grain weight and achieve high and stable production.
