Understanding its population dynamics and the influence of meteorological variables becomes important for decision-making in an integrated management context. The hypothesis is that the emergence of A. palmeri is influenced by thermal time and extreme weather events that occurred in the previous 45, 30 or 15 days. Objective: The work was aimed to detect the influence of meteorological variables and extreme weather events on the emergence of A. palmeri under field conditions. Methods: A field experiment was carried out in order to record seedling emergence of A. palmeri in two growing seasons, 2017/2018 (S1) and 2018/2019 (S2), in Argentina. Associations between weed emergence and thermal time (in growing degree-days GDD), meteorological variables or extreme weather events recorded at 15, 30 and 45 days before to each evaluation time were studied by regression, principal components and multiple correspondence analyses. Results: Thermal time was closely associated to the progress of cumulative emergence in both seasons, but the emergence periodicity was conditional with rainfall. The high precipitation during the spring determined a short lag period (121.8 GDD) in S2. Contrarily, the largest lag period (236.6 GDD) was detected in S1 related to a drought that concentrated the emergence in the beginning of the summer when the rainfall increased. Conclusions: Thermal time allows the cumulative emergence prediction; however, extreme weather events like drought induce quiescence, concentrating the emergence in a short period.","PeriodicalId":29845,"journal":{"name":"Advances in Weed Science","volume":"1 1","pages":""},"PeriodicalIF":2.1,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70674916","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Objective: Evaluate the reaction of 10 weeds frequently found in Alagoas to P. coffeae under greenhouse conditions. Methods: Two experiments were carried out in a completely randomized design, with 11 treatments, constituted of 10 weed species and the control ( Dioscorea cayenensis ) with eight replications. Plants were inoculated with 2,000 nematode specimens, nematode populations were evaluated in roots and soil 60 days after inoculation and the reproduction factor (RF) defined as RF = final population/initial population was calculated. Results: Euphorbia hyssopifolia showed RF=0 and was considered as non-host, whereas Chenopodium album, Amaranthus sp., Panicum maximum , Eleusine indica , Senna occidentalis , Emilia coccinea and Richardia brasiliensis , showed RF<1, being rated as poor hosts. Ricinus communis and Macroptilium lathyroides showed RF>1 only in the second trial and were classified as good hosts. Conclusion: Ricinus communis and M. lathyroides are potential sources of nematode inoculum for dry rot disease development.","PeriodicalId":29845,"journal":{"name":"Advances in Weed Science","volume":"1 1","pages":""},"PeriodicalIF":2.1,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70673769","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Several biological characteristics make these plants thrive in the environment and cause significant yield losses in many crops. Among the seven most important Amaranthus species in the Americas, four have populations with resistance to more than one mode of action ( A. hybridus , A. palmeri , A. retroflexus , and A. viridis ). While multiple herbicide-resistance in Amaranthus species is widespread, chemical control remains as one of the most important tools against those weeds. In this review, we compiled data from multiple sources on the efficacy of different herbicides across the most common modes of action that are used in Amaranthus management. Both PRE and POST herbicides are discussed, as well as the key factors to be considered when using each one of them. Residual PRE herbicides bring several advantages when managing Amaranthus species. These herbicides can avoid weed interference in the initial stages of crop development and provide a more favorable situation for weed control in POST. In addition, including PRE herbicides allows for the addition of alternative modes of action that are not available as POST treatments. Most POST herbicides have limitations regarding weed size and herbicide resistance status. Applying POST herbicides at the early growth stage of weeds is crucial to obtain efficacy. Finally, weed management sustainability depends on herbicides. Therefore, herbicide use should be combined with other weed control methods to avoid herbicide resistance evolution.","PeriodicalId":29845,"journal":{"name":"Advances in Weed Science","volume":"1 1","pages":""},"PeriodicalIF":2.1,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70675051","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
