"Wheat stripe rust is a major pest and disease controlled by the national joint prevention and control, which seriously threatens the safety of summer grain production." It mainly harms wheat leaves and leaf sheaths, generally reducing yields by 20%-30%, and almost no grain harvest when the most serious. Zhou Zhen, a relevant expert of the Municipal Digital Agriculture Rural Development Center, said. Recently, wheat stripe rust has occurred in many places in our province, posing a threat to the production of wheat in our city, and hereby appeal to the city's agricultural and rural departments and the majority of farmers and friends to monitor diligently, prevent and control it as soon as possible, and make every effort to prevent and control wheat stripe rust.
According to reports, wheat stripe rust, commonly known as jaundice, has the characteristics of wide occurrence area, fast epidemic rate and large damage loss. This year, stripe rust was seen early and had many disease points before winter in our province, and after spring, it was affected by the superposition of local pathogens and foreign pathogens, coupled with climatic conditions conducive to the infection and spread of pathogens, and the scope of occurrence was further expanded. However, this disease can be prevented and controlled, as long as monitoring, early investigation, early detection, and timely adoption of unified prevention and control, joint prevention and control, can effectively control the spread of this disease, to ensure a bumper summer grain harvest.
It is reported that in order to minimize disease losses, the Municipal Digital Agriculture Rural Development Center planned early, deployed early, and acted early, took effective measures, strengthened monitoring and early warning, and did a solid job in the prevention and control of wheat stripe rust. Since the spring, the Office of the Municipal Agricultural Plant Major Biological Disaster Emergency Response Headquarters has issued two consecutive documents to actively respond to the prevention and control work; the Municipal Agriculture and Rural Affairs Bureau attaches great importance to it, holds two consecutive meetings, makes solid arrangements for deployment, encrypts the frequency of monitoring and reporting, pays close attention to the monitoring census, and dispatches experts to provide guidance; the relevant responsible persons of the agricultural department have repeatedly investigated spring agricultural production, checked the occurrence and prevention and control of wheat stripe rust, and the municipal plant protection station organized agricultural technicians at all levels to sink to the front line and carry out wheat stripe rust investigation, monitoring, and prevention and control technical guidance services Fully mobilize township agricultural technicians, farmer technicians, socialized service organizations, and large planters to participate in disease investigations, and accurately grasp the development of diseases. Agricultural technicians in all districts and counties have taken active actions, adopted the method of packing villages and pieces, strengthened field monitoring and investigation, and comprehensively mobilized the masses to carry out mass prevention and group control.
Zhou Zhen told reporters that the strict prevention of wheat stripe rust mainly implements the prevention and control strategy of "investigation with medicine, dotting and protecting the surface" and "finding a point, preventing and controlling a piece; finding a piece, preventing and controlling the whole field", and timely controlling the incidence center; when the average disease leaf rate in the field reaches 0.5%-1%, organize large-scale emergency prevention and control, and achieve full coverage of prevention and control in similar areas. At present, it is found that stripe rust is mostly concentrated in the middle and lower leaves, the investigation is difficult, the source of bacteria is uncertain, from the investigation situation, it is likely that the invasion infection has been transmitted very early before seeing the disease. During the investigation, attention should be paid to the middle and lower leaves, and the amount of drug solution should be increased in the onset center of blockade, and the amount of liquid medicine must be penetrated. It can be used with 30% hexazole suspension 10-12 ml, 25% pentrazole water emulsion 25-35 ml, 12.5% enazolidin wettable powder 30-50 g or 25% propycyclazole emulsion 20-30 ml, 25 kg spray control with water; in the production, triazolone, fluconazole, ether ester, pyrazole ether ester, pyrimidine nucleoside antibiotics, enthome pentazole and other agents can also be selected. Severe plots are re-administered every 7-10 days. Pay attention to the safety of medication during prevention and treatment, do a good job of protection, and prevent the occurrence of poisoning accidents.
