Plant Protection Institute of Jiangsu Provincial Academy of Agricultural Sciences in November 1987 5-6 in Nanjing held a flat broom grass comprehensive control system research report. At the meeting there were 20 representatives from cooperating units of agricultural research, plant protection and land reclamation system in Jiangsu and Shanghai. At the meeting, the delegates reported the results of their studies on the biological characteristics of Balasagrass and its supporting techniques, and put forward some questions that still need to be studied. The deputies pointed out that through the survey from 1986 to 1987, the damage area of flat barn grass in paddy fields in Jiangsu and Shanghai was about 340,000 hectares, with the density generally ranging from 20 to 150 per square meter and over 350 severely, mainly Distributed in Huaibei and the coast
