(Euphorbiaceae), which is native to Mexico, was first recorded at Okinawa-honto Island, Japan in 2004. The authors recognized E. graminea growing in a wide range of Miyako-jima Island and invading sugarcane fields. To confirm the E. graminea distribution in the Miyako-jima region and to elucidate its expansion process, we conducted a herbarium survey, re-examination of earlier works related to weeds in sugarcane fields, and field surveys of 2017–2018 and 2019. The first record of the species in the Miyako-jima region was in 2007. Subsequently, within about five years, it expanded its distribution quickly and invaded sugarcane fields. Within about five years, it spread to almost all areas, except for a few islands. It was found in 20–30% of all the sugarcane fields in 2019. Our results suggest that E. graminea has become a major weed in sugarcane fields of the Miyako-jima region. Considering the rapid expansion of its distribution in the Miyako-jima area, it is expected to be necessary to monitor the alien species carefully in sugarcane fields of other regions of Okinawa Prefecture.","PeriodicalId":17635,"journal":{"name":"Journal of Weed Science and Technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78014549","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Because the error between the estimated and observed number of days for a certain soybean leaf stage was 0.4–1.9 (RMSE of 0.11–0.56), the model was approved as practical for determining the time of applications of herbicides. In the fields where bentazon and glufosinate were applied at the 2- and 5-leaf soybean stages, respectively, the per centages of area infested by Ipomoea coccinea or I. lacunosa tended to decrease in comparison with those where the herbicide applications were delayed or not performed. The effects of sequential herbicide applications in two successive years to reduce the infested area were unclear, because 52–81% of the total area of the soybean fields was not treated at the scheduled time due to bad weather. Ipomoea lacunosa was more difficult to control than I. coccinea because it grew rapidly and were missed easily at the application time of herbicides. In particular, there was a greater percentage of area infested by morning glory species, in comparison to the previous year, with increase in delay of application of bentazon. Therefore, timely control of bentazon at the 2-leaf stage of soybean is important for control of morning glory.","PeriodicalId":17635,"journal":{"name":"Journal of Weed Science and Technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90424732","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
