Please give guidance due to the continuous improvement of the degree of wheat mechanical harvest, a large number of straw returned to the field, wheat bran blown in the field, the occurrence of wheat scab gradually aggravated.

Wheat scab with what method control? Please give guidance Due to the continuous improvement of wheat mechanical harvesting, a large number of straw returned to the field, wheat chaff scattered in the field, so that wheat scab gradually aggravated. Scab is one of the main diseases that harm wheat. The ear of wheat that is harmed is pink, so it is called scab. It has been observed that most wheat varieties are susceptible to scab under drought conditions. Especially in high water and fertilizer plots, warm wheat and new wheat series varieties were more seriously infected, and the panicle rate of Zhoumai 16 and Bainong Aikang 58 could reach 10%. Scab not only affects wheat yield but also causes wheat grain spoilage and deterioration, and the toxin secreted by the disease pathogen can also poison humans and animals. Wheat scab is a disease which is difficult to control thoroughly. Most farmers do not select disease-resistant varieties when sowing, and if they do not control them in time, they will suffer greater losses. According to the observation of our field in recent two years, wheat scab rarely occurs from jointing to booting stage, mainly damaging wheat ears from heading to full flowering stage. The temperature was high during this period, so it was popular very quickly. Most farmers know less about scab, and they don't pay enough attention to it ideologically. It is difficult to find it without careful observation at the early stage of disease. If it is not controlled in time, it will suffer from continuous rainy weather in full bloom, and a large number of withered white ears will appear in the field within a few days. At this time, it is difficult to control the re-spraying treatment. But the wheat field which control in time has obviously lighter disease. Because the control time is short, see the ear on individual glume white dry, and red spots should be timely spraying control. It is better to spray carbendazim 100g or 50g of difluconazole (Gragolide) and water 30kg per mu to control wheat scab at the early stage of heading because it is a fungal disease according to weather changes. Because scab mainly harms wheat ears, it is necessary to use a good atomized sprayer, raise the spray rod as much as possible, focus on spraying ears to make wheat ears evenly treated, and according to weather conditions, the maximum interval is 7 days, and the second prevention and control is carried out when wheat ears are full and a large number of flowers bloom. If the weather is cloudy and the disease is serious, it still needs to be controlled once at the early stage of wheat filling to achieve better control effect. According to our field observation, only once control in wheat heading to grain filling stage, spraying a large amount also failed to achieve good results. Therefore, the author suggests that farmers must seize the opportunity, improve awareness, fear trouble, overcome the idea of relying on heaven to control diseases as much as possible, in order to achieve yield and income.
