expert: the disease is harmful, causing wheat to reduce production and even
wheat stripe rust is what is the disease? Shanghe County plant protection station station master Du Baojiang told reporters that wheat stripe rust mainly occurs on wheat leaves, followed by leaf sheath and stem And panicle. When infected at seedling stage, there will be many layers of wheeled yellow summer spores on the leaves. In the early onset of adult plant leaves, the summer spores are small long strips, fresh yellow and oval, parallel to the veins and arranged in rows, like a stitch like stitches rolled by a sewing machine.
wheat stripe rust propagated in the wind. It could propagate from air to air at a distance of several hundred meters to more than 1000 kilometers away from the air. Not only that, the disease spread quickly, the spore heap of the pathogen was 8 to 10 days, each spore heap could produce 1800 spores each day, overlapping generations and intersecting with each other. Moreover, with the increase of temperature in the field, spore flow will be formed under the action of wind.
Du Baojiang pointed to an infected leaf and said, "this leaf is infected with wheat stripe rust". If there is no disease control, the spore stack on leaves will be more and more, which will affect the photosynthesis of plants. He said that when wheat is infected with this disease, it will affect its development and grain filling, and make wheat grain thin and thin, which will affect its quality and yield. Under normal circumstances, wheat will be reduced by 10% to 30% after the disease, and the yield will be reduced by more than 50% or even if it is serious.
the dozen acres of wheat field were seriously affected by disease. Before we checked here, we found that more than 140 leaves had been infected at the same time in the range of 1 square meters. According to Du Baojiang, the basic prevention and control is being carried out for the first time. After the end of prevention and control, it will find out again. If the end of prevention and control still can not reach the ideal effect, two prevention and control will be carried out.
Department: after prevention and control will not have a greater impact on the production of summer grain
this, Wang Fengguang, deputy director of the Ji'nan Municipal Agriculture Bureau, said: at present, the counties and cities are tightening the prevention and control of diseases, the first basic prevention and control will end in 7, if the prevention and control effect is not ideal, the two prevention and control will be carried out in the key areas. Prevention and control will not have much impact on the production of summer grain this year.
reporter learned from Ji'nan agricultural bureau that wheat stripe rust diseases were found in all districts and counties of the whole city, and the Da rate was 100%. In May 2nd, the relevant units forwarded an emergency notice on the prevention and control of wheat stripe rust. At the same time, 4 steering groups were set up to mobilize the staff of the county and urban frontline workers to understand the situation and guide the disease prevention and control. The Ji'nan municipal government urgently issued 6 million yuan of funds for drug procurement.
at present, our city has completed 30.45 tons of emergency pesticide procurement, 22.5 tons of fungicides, and all the pesticides have been distributed to counties and townships. Shanghe, Licheng and other counties and counties have arranged special matching funds, and adopted unified rule and group prevention and control. We strive to use 3 days to complete the first round of basic prevention and control. Wang Fengguang said.
it is understood that the prevention and control work will be carried out through the combination of the specialized control and the self-control of the farmers, and the daily prevention and control capacity of the socialized service organization is over 500 thousand mu. After the end of the basic prevention and control, we will further organize the investigation and conduct the two focal protection for the place where the disease occurs repeatedly. Make sure that no dead ends are left out so that diseases can be effectively controlled. Wang Fengguang said: the prevention and control of disease need not only the rule of prevention and control, but also encourage the farmers to carry out spraying by themselves. Combined with the current disease situation and the prevention and control work, it will not have much impact on the production of summer grain after the end of the control.
