“…The ability to reduce disease severity is due to the ability of plants to increase the production of phytoalexins-sakuratenin against P. oryzae. Phytoalexins-sakuratenin increased rapidly 2 days after silica application [27].…”

An increase in the cropping index causes the land to be cultivated more intensively and has impact on decreasing Silica content (Si) so that it is necessary to add Si to support the growth of rice plants, especially on intensive land. This research aims to study the effect of biosilica on the growth of the vegetative phase of several very early maturing rice varieties. The research was conducted from September to December 2022 in Gorontalo using a Split Plot Design. The variety as the main plot and dose of liquid biosilica as a subplot. The results showed that the treatment of Inpari 19 variety with biosilica dose of 4.5 L ha−1 had the highest number of stomata and stomata density. Individually, the Cakrabuana variety has the highest plant height, the highest number of tillers and the smallest flag leaf angle. Meanwhile, biosilica at a dose of 4.5 L ha−1 had the highest plant height and the smallest flag leaf angle. In addition, treatment of Inpari 13 and Inpari 19 varieties with biosilica dose of 3.0 L ha−1 gave the best effect on the development of blast disease intensity.

“…Dentre os diferentes mecanismos de defesa promovidos pelo silício também há o aumento da atividade de enzimas antioxidantes, como a peroxidase (POD) e superóxido dismutase (SOD), as quais estão relacionadas com a lignificação, sendo a lignina, uma mistura complexa de compostos fenólicos (Boerjan, Ralph & Baucher, 2003;Fleck, et al, 2011;Tesfay et al, 2011;Asgari, et al, 2018). O silício facilita a produção de enzimas relacionadas à defesa como a catalase, glucanase, peroxidase e a fenilalanina amônia-liase, que são precursoras da síntese de compostos antimicrobianos, lenhina, suberina, tanino, quinonas, flavonóides e fitoalexinas, conferindo assim, respostas de defesa da planta a insetos e patógenos (Gomes, et al, 2005;Ye, et al 2013;Wang, et al, 2017;Ng, et al, 2021).…”

A aveia branca é uma espécie de inverno com inúmeros benefícios aos sistemas de cultivo e na alimentação animal e humana. É reconhecida como alimento nutracêutico pelos benefícios à saúde. Esta condição tem promovido o aumento das áreas de cultivo buscando atender a demanda, porém, favorecendo o surgimento de doenças fúngicas, responsáveis por danos expressivos na produtividade e qualidade de grãos. A ferrugem da folha (Puccinia coronata f. sp avenae) e a helmintosporiose (Drechslera avenae (Eidam) Sarif) são as mais relevantes pela sua agressividade. Estas doenças não são controladas satisfatoriamente pela resistência genética e sua ocorrência e agressividade está relacionada a presença de ambiente favorável ao desenvolvimento dos fungos, hospedeiro suscetível e patógeno virulento. O uso de fungicida tem sido a alternativa mais eficiente de controle, na garantia de produtividade com retorno econômico ao agricultor. Entretanto, o uso de agrotóxicos tem gerado discussões acerca dos efeitos adversos ao ambiente, a segurança alimentar e a saúde pública, condição que reforça a busca por sistemas agrícolas mais sustentáveis. Esta revisão busca apresentar uma profunda discussão acerca dos agrotóxicos e alternativas mais sustentáveis que possam reduzir e/ou evitar a incidência e severidade de doenças fúngicas na aveia. Dentre as alternativas, a discussão engloba duas potenciais tecnologias de manejo, a semeadura envolvendo zonas de escape à restrição ao desenvolvimento dos fungos e uso de indutores abióticos de resistência por silício e potássio.

“…Selain SiO 2 , terdapat beberapa bentuk sumber silika yang mungkin digunakan untuk aplikasi di atas permukaan tanah, di antaranya Ca 2 SiO 4 dan Na 2 SiO 4 . Aplikasi silika pada daun dalam bentuk Ca 2 SiO 4 lebih efektif dalam menekan keparahan penyakit blas yang disebabkan oleh P. oryzae, diindikasikan dengan nilai AUDPC lebih rendah dan berbeda nyata dibandingkan dengan perlakuan kontrol dan SiO 2 (Ng et al 2021). Aplikasi silika dalam bentuk Ca 2 SiO 4 pada jahe belum pernah dilakukan sebelumnya, oleh karena itu aplikasi silika dalam bentuk selain SiO 2 dapat dipertimbangkan untuk uji lanjut.…”

Pyricularia zingiberi merupakan penyebab penyakit bercak daun dominan di Indonesia. Pengendalian penyakit bercak daun masih bertumpu pada fungisida kimia. Kombinasi teknik pengendalian serta ketepatan waktu aplikasi fungisida perlu ditentukan untuk meningkatkan efektivitas pengendalian serta mengurangi dampak negatif penggunaan fungisida kimia. Penelitian ini bertujuan menentukan kombinasi pemberian fungisida dan pupuk silika serta waktu yang efektif untuk pengendalian penyakit bercak daun. Penelitian disusun dalam rancangan petak-petak terbagi, dengan aplikasi pupuk silika sebagai petak utama, fungisida sebagai anak petak, dan waktu aplikasi sebagai anak-anak petak. Pupuk silika (20 mL L-1) diaplikasikan pada tanaman jahe merah umur 4 minggu dan kemudian tanaman diinokulasi dengan P. zingiberi pada umur 8 minggu. Fungisida mulai diaplikasikan sesuai dengan perlakuan (umur 12, 14, dan 16 minggu). Tidak terdapat interaksi antara ketiga faktor yang diuji. Aplikasi silika dalam bentuk SiO2 memberikan pengaruh tidak nyata pada keparahan serta laju perkembangan penyakit. Aplikasi silika meningkatkan kadar fenol dalam tanaman jahe merah. Pestisida nabati berbahan minyak cengkeh menginduksi sintesis asam salisilat, namun tidak signifikan dalam menekan laju perkembangan penyakit bercak daun. Mankozeb lebih efektif menekan laju perkembangan penyakit bercak daun dibandingkan dengan perlakuan lain. Waktu aplikasi fungisida disarankan pada saat tanaman berumur 14–16 minggu atau saat gejala bercak daun mulai terlihat. Monitoring berkala perlu dilakukan.
