Bacterial bacterial blight is a bacterial disease in rice. It occurs from the seedling stage to the heading stage, but the incidence is highest in the highest tiller stage, young panicle differentiation stage, and early heading stage. The disease will affect rice heading grouting, increased empty grains, reduced grain weight, resulting in damage to rice yield.
Symptoms: yellowish-green or dark green spots occur at the tip or edge of the leaf, and the veins in the posterior vein expand to become yellowish-brown. The boundary of the lesion is sharp; the lesions are irregularly corrugated on the disease-resistant varieties; The leaves are green, the water loss is fast, and the inside volume is blue and dry. After the death of the diseased plant was grayish white.
The first diffuse source of germs 1. Non-rotated sick rice (miscellaneous) grass; 2. By wind and rain, dew, irrigation water, insects and human factors; 3. Diseased seeds for long-distance transmission.
Comprehensive prevention and control measures 1. Selection of disease-resistant varieties, cultivation of disease-free and strong; 2. Treatment of straw, to eliminate the source of bacteria: 3. Strengthen the management of flood prevention and string prevention; 4. Increase the pests of rice planthoppers and other pests Kill; 5. To strengthen management, pay attention to the proportion of nitrogen, phosphorus, potassium fertilization, timely field; 6. Pharmacy timely prevention and treatment.
There must be three points in choosing the drug selection at the same time: 1. It must be a complete product with three certificates; 2. The product must be the product of bacterial blight of rice that is confirmed by the Ministry of Agriculture's registration; 3. It must be renewed and effective. Label specifications, date clear, quality qualified products. In our province, we only know that 20% of the leaves are used earlier. Here, we recommend it carefully: 50% of Green O-cyanuric acid, an excellent agent for controlling bacterial blight in rice.
Green O - cyanuric acid Green O - cyanuric acid role in the prevention and control of bacterial blight in rice: 50% Luomao - cyanuric acid (former name: Jin Xiaokang) is the prevention and treatment of bacterial blight caused by the registration certificate of the Ministry of Agriculture The good medicine. After trials in Kunming, Honghe, Wenshan, Yuxi, Chuxiong, Dali, Baoshan, etc., in our province, the results were very good and safe. It is a highly efficient, broad-spectrum, low-toxicity and environmentally compatible cross-century new pesticide. The pesticide spraying and the surface of the crop can slowly release the acid of sub-oic acid. In the water, the acid of sub-oAA is four times higher than the activity of hypochlorous acid and has strong ability of killing bacteria; the mother of sub-oic acid is released through internal absorption conduction. The formation of triazine dione and s-triazine has a strong ability to kill bacteria, germs and viruses; it has both the role of systemic protection and disease treatment, and it can effectively kill a variety of pathogenic bacteria. Can promote vegetative growth of crops.
Experts from China Agricultural University recommend that green bromide-cyanuric acid can also be used to treat bacterial leaf streak, stripe leaf blight, rice blast, and sheath blight on rice, and it can cure dead roots and rotten seedlings in vegetables and gardening. and many more. Due to the three-dimensional agricultural three-dimensional climate in our province, it is still necessary to follow the procedures for demonstration, demonstration, and re-application.
