Release time: 2023-05-08
Recently, Jianghuai, HuangHuaihai and other major wheat producing areas have heavy rainfall weather, the weather forecast in the next 10 days will still have a number of rainfall processes, wheat SCab epidemic risk increased。A few days ago, the Ministry of Agriculture and Rural Affairs issued an urgent notice, requiring all localities to continue to do a good job in the prevention and control of SCAB and ensure a stable wheat harvest on the basis of the initial results achieved in the early prevention and control。
Adhere to partition classification guidelines。Jianghuai, southern Huanghuai and other common SCab recurrence areas，Wheat entering the late grout or milk-ripening stage，Strengthen the determination of wheat ear carrier rate in late filling period，Necessary remedial and control measures should be taken for areas with more than 20% bacteria carrying rate.In the early stages of heading and flowering or filling，Combine "one spray and three prevention"，Catch the rain before prevention or repair after rain prevention，Effectively reduce disease occurrence, reduce toxin pollution。Huanghuai northern, North China and other SCab occurrence areas, pay close attention to weather changes, once the rainy weather, combined with the "one spray three prevention" to seize the "window period" of earing and flowering, the implementation of "see flowers and medicine" prevention and control measures, strictly prevent the epidemic of the disease。Adhere to scientific selection of medicinal drugs。According to the principle of using less drugs and using good drugs，The high efficiency agents and their compound preparations, such as cyanopropyl, propylothiazole and flumazolamide, were selected，And self-propelled wide application machinery, plant protection drones and other efficient application machinery，Implement small aperture nozzle spray，Ensure that the droplet size is appropriate and the liquid is evenly distributed，Improve the effect of disease prevention and toxin control。We will do a good job in field drainage management。Organize the clearing of the furrow in time, so that the rain stops the dry field, reduces the field humidity, and avoids the prevalence of diseases aggravated by the field high humidity and sultry microclimate。Make sure the wheat is dry and stored。The wheat is harvested in time at maturity, dried and dried to ensure that it is dry and stored in the warehouse, so as to avoid the excessive humidity of the wheat grain resulting in the re-infection and propagation of scab, producing toxins and affecting the quality of wheat。
It is reported that the Party committee and government at all levels attach great importance to the agricultural and rural departments to strengthen the organization and launch, plant protection agencies to strengthen the guidance services, the broad masses of farmers have responded positively, and have implemented the wheat SCab "see flowers and medicine" and "repair and prevention after rain" area 3.At 5.3 billion mu, the prevention and control has achieved phased results。At present, only sporadic detection of ear disease was found in local fields along the Yangtze River, southern Henan and southern Shaanxi, and the occurrence area was 2.95 million mu, which was significantly lower than that of the usual year and decreased by 44%。
