“…Dessa maneira, é pertinente concluir que os óleos essenciais possam ser utilizados em tratamentos sanitários de sementes, contudo o efeito desses óleos sobre a germinação e o desenvolvimento das plântulas precisa ser também investigado (Christian;Goggi, 2008). Os estudos para verificar a viabilidade do emprego dos óleos podem indicar estes como possíveis substitutos aos antifúngicos já utilizados e também revelar novas moléculas a serem utilizadas para síntese de novos antifúngicos comerciais (Duke et al, 2010).…”

RESUMO: O desenvolvimento de pesticidas é uma constante no setor agropecuário, visando oferecer produtos menos agressivos ao meio ambiente e novos princípios ativos, evitando o aparecimento de resistência. O estudo de alternativas aos fungicidas utilizados no tratamento de sementes tem nos óleos essenciais um campo para prospecção. Esta pesquisa teve como objetivo avaliar os efeitos dos óleos essenciais provenientes de folhas de C. citriodora e E. camaldulensis , em sementes de milho da variedade AL Bandeirante, de diferentes localidades. A qualidade fisiológica e sanitária das sementes foi avaliada quando se trataram as amostras utilizando os óleos individualmente, a mistura equitativa desses óleos e o tratamento com um antifúngico comercial. Foi observado que o tratamento com os óleos C. citriodora e E. camaldulensis e a mistura dos óleos não afetou a germinação imediata das sementes de Avaré. No lote de Bernardino de Campos, o tratamento com C. citriodora foi prejudicial; com o E. camualdulensis , apesar de não diferenciar estatisticamente dos demais, diminuiu a germinação, o que impediria sua utilização como semente, segundo o padrão normatizado (de 85%) pelo Ministério da Agricultura, Pecuária e Abastecimento (MAPA). O óleo de E. camaldulensis apresentou efeito fitotóxico, diminuindo o comprimento das plântulas; a acetona utilizada como solvente não influenciou sobre a germinação, mas apresentou efeito fitotóxico após o envelhecimento acelerado. A aplicação dos óleos isoladamente foi capaz de diminuir a incidência dos fungos dos gêneros Penicillium e Fusarium , mas para Aspergillus o comportamento foi semelhante ao antifúngico comercial, não apresentando efeito quando comparado ao tratamento testemunha.

“…Niclosamide has become the mainstay of GAS control and eradication programs [8]. Synthetic molluscicides are known for their knock-down effect; however, their negative impact on the environment and the high costs of application have stimulated interest in the search for plant-derived molluscicides which are target specific, and environmentally and toxicologically safe [9][10][11]. Botanical pesticides have long been explored as effective alternatives to synthetic chemical counterparts due to their low toxicity to non-target organisms, their biodegradability, and due to them being less expensive in their crude form, in addition to the prevention of development of resistance against phytochemical mixtures [12][13][14][15].…”

Development and Evaluation of Poly Herbal Molluscicidal Extracts for Control of Apple Snail (Pomacea maculata)

2017

Golden Apple Snail (GAS) is the most destructive invasive rice pest in Southeast Asia. The cost of synthetic molluscicides, their toxicity to non-target organisms, and their persistence in the environment have propelled the research of plant-derived molluscicides. Most research efforts have focused on individual plant extracts for their molluscicidal potency against GAS and have not been proven to be entirely effective in rice field conditions. Selective combination of synergistically acting molluscicidal compounds from various plant extracts might be an effective alternative. In this direction, ethanolic extracts from six different plants (Neem, Tobacco, Nerium, Pongamia, Zinger, and Piper) were evaluated against Pomacea maculata Perry. Of the various combinations studied, a binary extract (1:1) of nerium and tobacco (LC 90 177.71 mg/L, 48 h), and two tri-herbal extract formulations (1:1:1) of (nerium + tobacco + piper) and (nerium + tobacco + neem) were found to be most effective, with LC 90 values of 180.35 mg/L and 191.52 mg/L, respectively, in laboratory conditions. The synergistic effect of combined herbal extracts resulted in significant reduction in LC 90 values of the individual extracts. The findings of this study demonstrate that the selective combinations of potent molluscicidal herbal extracts are effective for management of P. maculata under laboratory conditions.

“…Therefore, new and alternative mosquito control agents are emerging. Plant-derived products including essential oils (EOs) may offer an alternative and effective means of managing populations of mosquitoes [8][9][10][11]. As a part of our ongoing investigation of Turkish medicinal and aromatic plants, we report on the chemical composition of the aerial parts of S. gummiferum subsp.…”

“…The primary method of mosquito control relies on the use of biological and/or synthetic insecticides [6]. Due to long term repeated chemical use, mosquito species have acquired resistance to commonly used insecticides, and especially against commercial pyrethroids [8][9][10][11]. Therefore, new and alternative mosquito control agents are emerging.…”

Mosquitoes are vectors for many pathogens and parasites that cause human diseases including dengue, yellow fever, West Nile, chikungunya, filariasis and malaria which cause high rates of human morbidity and mortality under extreme conditions. Plants are an excellent source for mosquito control agents because they constitute rich sources of bioactive chemicals. They are also biodegradable and environment-friendly. The present study reports on the larvicidal activity of the essential oil of Seseli gummiferum. subsp. ilgazense (Apiaceae) against Aedes aegypti larvae. Essential oil showed 100 and 70% mortality at 125 and 62.6 ppm, respectively, with no mortality at 31.25 ppm. Aerial parts of S. gummiferum subsp. ilgazense were subjected to hydrodistillation to yield 0.6% oil. The essential oil was analyzed by GC-FID and GC-MS techniques. The main constituents in the oil were sabinene (28.8%), germacrene D (9.5%) and α-pinene (7.2%).
