This paper reviewed general occurrence situation of wheat scab in eastern Jiangsu, and summarized its occurrence characteristics in last decade. The disease prevalence was elaborated from the aspects of fungal source quantity, chmatic conditions, cultivation modes, variety resistance and pesticide resistance. The author put forward a series of measures and countermeasures, including strengthening resistance monitoring and early warning, promoting and cultivating disease-resistant varieties, compressing planting area of direct seeding rice, canting out chemical control scientifically, and realizing unified prevention and control, in order to provide a scientific basis for the control of wheat scab.展开更多

文摘With the increasing prevalence frequency and aggravating harm degree in the 21st century, wheat scab had become a recurrent disease in eastern wheat area of Jiangsu Province. This paper reviewed general occurrence situation of wheat scab in eastern Jiangsu, and summarized its occurrence characteristics in last decade.

The author put forward a series of measures and countermeasures, including strengthening resistance monitoring and early warning, promoting and cultivating disease-resistant varieties, compressing planting area of direct seeding rice, canting out chemical control scientifically, and realizing unified prevention and control, in order to provide a scientific basis for the control of wheat scab.
