Pay attention to the prevention of rice spikes
The panicle-necked cricket, commonly known as hanging neck and neck ridge, is one of the main diseases of rice in our county in the later period. The disease has suffered heavy losses in some towns and villages last year. At present, Hayabusa and high-quality conventional rice are more serious. Hybrid rice (Ganyou 725, Gangyou 177, Fengyou Xiangzhan, etc.) in rice blast disease-prone areas has already developed leaf carp to varying degrees, laying a wealth of bacteria for the occurrence of panicle blast. source. To this end, all localities must earnestly change their work style, overcome the paralysis, take strong measures, and timely control and control the epidemic of panicles and cervix to ensure a high yield of rice. First, the trend It is estimated that this year's panicle blasts are moderately heavy and occur locally, with an area of ​​50,000 mu. in accordance with: 1, varieties of poor resistance. All the varieties cultivated in our county this year have no strict resistance to rice blast, laying the foundation for the occurrence and epidemic of rice blast. After investigation, the incidence of rice blast disease in our county is more and more serious. With a large number of susceptible varieties and a wide planting area, it is also a source of infection for the occurrence and epidemic of rice blast. 2, ample bacteria source. Last year, the incidence of rice blast in our county was large and the damage was heavy. The diseased rice straw remained large. According to the survey, the average seed carrier rate was 6.9%, and the average carrier rate of rice straw was 10.1%, which created favorable conditions for the occurrence of rice blast disease. 3. The occurrence of heavy leafhoppers. At present, there is an epidemic situation in Yexian County, where there are 16 towns and townships, an area of ​​8,000 mu, and a large accumulation of bacteria in the field, which lays the foundation for the late-stage cervical plague. 4, the climate is suitable. According to the meteorological department's forecast, more rainfall in July this year will benefit the occurrence, prevalence, and damage of panicles and necks. Second, prevention advice 1, control of the appropriate period: the rice's tillering peak and booting heading is the most susceptible stage. If the temperature is in the range of 20-300C, especially 24-280c, and the relative humidity is above 90%, the weather will continue to be cloudy and rainy, and panicle blasts and epidemics will occur most easily. The panicle-necked canopy is a disease that can be prevented and cannot be treated. Once it has become a disaster, it can only be applied during the period from the break to the beginning of earing (before 10% of the ear). The south towns (such as Zhonghe Film, Luodu Film, etc.) are controlled from late June to early July, and other townships are controlled from the end of July to the middle of July. The key crop control plots such as field plots, rice blast disease areas, susceptible rice varieties, conventional rice, and seed production bases were planted with the second medicament 5 to 7 days after the first application. However, it must not be later than the heading period to ensure the control effect. 2. Prevention and control of key points: The frequent occurrence of panicle blasts in the past years and the occurrence of leaf blast and disease-affected varieties in the planting areas are the focus of prevention and control. 3, drugs and usage and dosage: Mu 75% Fengdeng 20-30 grams or 40% Fuji No. 1 100 ml watered 45-50 kg conventional spray. Third, pay attention to matters 1. Adhere to the principle of prevention, strictly control the prevention and treatment time, and whether the application during the break-opening period is the key to success or not, and whether the application at the full heading stage is a measure to collect more revenue and less income. 2, to avoid spraying when spraying. 3, require enough medicine, enough water, spray evenly on the ear layer. 4. During the period of prevention and treatment, it rains. After the rain stops, immediately remove the dew and take the pesticide.
