“…Albuquerque et al (2008) reports a lack of knowledge about herbicide selectivity in castor bean crops, which has hampered crop expansion into larger production areas. Vitorino et al (2012) states that many herbicides are used for controlling castor beans in other crops, implying that limitations may exist in finding products to control eudicotyledonous weeds while simultaneously being selective to castor beans.…”

“…Among the herbicides that would control castor bean infestations in the successions crop are those used for pre-emergence: atrazine singly or in a mixture with simazine or metolachlor THEISEN et al, 2006), diclosulan and2,4-D (ALBUQUERQUE et al, 2008), flumetsulan and imazaquin (RAMOS et al, 2006;ALBUQUERQUE et al, 2008), imazapic (CARDOSO et al, 2006ALBUQUERQUE et al, 2008), imazapyr (ALBUQUERQUE et al, 2008, sulfentrazone RAMOS et al, 2006) and isoxaflutole (RAMOS et al, 2006;ALBUQUERQUE et al, 2008;MASCARENHAS et al, 2010;MACIEL et al, 2011); as well as dicotyledon herbicides used for application as a post-emergence: pyrithiobac-sodium, lactofen, fomesafen (SOFIATTI et al, 2008), trifloxysulfuron-sodium (FERREIRA et al, 2009a and saflufenacil (MONQUERO et al, 2011).…”

“…In general, for many agricultural crops, integrated weed management has contributed to more effective and sustainable weed control (ACCIARESI et al, 2003;MACHADO et al, 2006;GALON et al, 2007;RONCHI et al, 2008;PACHECO et al, 2009;FERREIRA et al, 2010;BIANCHI, 2010). This integration uses several control techniques to minimize weed interference in crops, keeping weed populations at levels below those that cause economic damage, while also mitigating negative effects on the environment (RONCHI et al, 2010).…”

ABSTRACT. Castor bean crops are agriculturally relevant due to the quality and versatility of their oil, both for the chemical industry and for biodiesel production. Proper weed management is important for both the cultivation and the yield of castor bean crops; therefore, the intention of the present work is to review pertinent information regarding weed management, including the studies regarding weed interference periods, chemical controls for use in different crop production systems and herbicide selectivity, for castor bean crops. Weed science research for castor bean crops is scarce. One of the main weed management challenges for castor bean crops is the absence of herbicides registered with the Ministry of Agriculture, Livestock and Food Supply (MALFS). Research for viable herbicides for weed control in castor bean crops should be directed by research and/or rural extension institutions, associations and farmers cooperatives, as well as by manufactures, for the registration of these selective herbicides, which would be primarily used to control eudicotyledons in castor bean crops. New studies involving the integration of weed control methods in castor bean also may increase the efficiency of weed management, for both small farmers using traditional crop methods in the Brazilian Northeast region, as well as for areas with the potential for large scale production, using conservation tillage systems, such as the no-tillage crop production system. Keywords: weed competition, herbicides, selectivity, Ricinus communis. Estratégias de manejo de plantas daninhas na cultura da mamoneira RESUMO.A cultura da mamoneira apresenta destacada relevância principalmente devido à qualidade e versatilidade de seu óleo tanto na indústria química como para produção de biodiesel. Considerando a importância do manejo de plantas daninhas para o cultivo e produtividade da mamoneira, o presente trabalho teve como objetivo abordar as principais informações disponíveis sobre o assunto, entre as quais foram destacados os estudos de períodos de interferência das plantas daninhas, controle químico em diferentes sistemas de produção e seletividade de herbicidas à cultura. Verificou-se que os resultados de pesquisa sobre o manejo da cultura da mamona são escassos, nos mais variados aspectos da ciência das plantas daninhas. Uma das principais dificuldades para o controle de plantas daninhas na cultura da mamona é a atual ausência de herbicidas registrados no MAPA. As informações existentes descrevem perspectivas viáveis que necessitam ser direcionadas por instituições de pesquisa e/ou extensão rural, associações e cooperativas de produtores rurais, assim como por empresas fabricantes, para o registro de herbicidas seletivos, principalmente para o controle de espécies eudicotiledôneas. Novos estudos envolvendo a integração de métodos de controle de plantas daninhas em mamoneira também podem aumentar a eficiência no manejo, tanto para pequenas propriedades da tradicional região do Nordeste brasileiro, assim como para áreas com potencial de p...

Tillage is the most important age old practice, which is usefull to create favourable seed bed for sowing of seeds. It also plays a significant role in weed species persistence and its distribution in agriculture fields. Summer plough kills the weed seeds by exposing it to the sun light. Deep tillage helps for the development of enforced dormancy by burring the newly shredded seeds in the deeper layer of soil. Till now no herbicide is available to kill the weed seeds, tillage improves nitrogen mineralization thus in turn enhance the germination of weed seeds. After weed seed’s germination, controlling can be done easily with either spraying of herbicides, mechanical and manual means. Now a day’s conservation tillage or zero tillage concept is getting picking up. So it is highly important to study the effect of reduced tillage on weeds. Most of the research evidences found that under reduced tillage condition, weed seed accumulation is higher in upper layer of the soil. Annual weed population is predominant in reduced or no tilled soil. In no tillage system before planting soil was applied with non-persistent non selective herbicides to control weeds effectively.
