Blast disease is an important disease of rice caused by Pyricularia oryzae. The use of antagonistic fungi from the rhizosphere of rice plants has the potential to control plant pathogens. One of them is from the genus Aspergillus. This research aims to test the ability of Aspergillus genus fungi in suppressing the intensity of P. oryzae attack on ciherang rice varieties. The research methods were isolation and identification of rhizosphere fungi, propagation of P. oryzae, antagonistic test of rhizosphere fungi against P. oryzae in vivo, and reisolation of fungi from rice plant tissues. This research used a completely randomised design (CRD) consisting of 9 treatments and 3 replications. Data obtained from this research were statistically analysed using analysis of variance (ANOVA) and Tukey's honest significant difference test at the 5% level The results showed that Aspergillus sp1 and Aspergillus sp2 fungi could significantly reduce the intensity of blast disease attack caused by P. oryzae isolates from Moncongloe and Simbang regions..

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.

Gangguan patogen Pyricularia orizae dapat mengakibatkan beberapa hal yaitu turunnya kualitas padi yang disebabkan oleh rusaknya bentuk fisik dan menurunnya proporsi produksi. Oleh karena itu penelitian ini bertujuan untuk mencari upaya dalam penanggulangan produksi padi agar tetap optimal. Oleh karena itu, diperlukan suatu alternatif pengendalian yang lebih ramah lingkungan yaitu dengan penggunaan fungisida nabati. Fungisida nabati berasal dari tumbuh-tumbuhan yang diproses dalam bentuk ekstrak atau dibuat menjadi konsentrat namun tidak mengubah struktur kimia, sehingga residu fungisida nabati lebih cepat terurai. Tumbuhan yang dapat dimanfaatkan sebagai fungisida nabati antara lain yaitu sirih hijau ( Piper betleL.). penelitian dilakukan secara eksperimen dan disusun berdasarkan Rancangan Acak Lengkap (RAL), yang terdiri dari 5 perlakuan dan 5 ulangan, data yang diperoleh dianalisis secara statik dengan analisis ragam dan uji lanjut dengan Duncan's New Multiple Range Test (DNMRT) pada taraf 5%. Hasil penelitian identifikasi patogen P. orizae dan pemberian ekstrak daun sirih dapat menghambat pertumbuhan P. orizae di Lab dan di rumah kasa pada konsentrasi masing-masing (0 mm, 23,8 mm, 39 mm, 38,2 mm, dan 34,8 mm), dan rumah kasa (60.0 mm, 55.0 mm, 55.0mm,55.0mm, dan 50.0mm), tinggi tanaman pada minggu ke 15 (86.2 cm, 81.1 cm, 93.5cm, 86.4 cm, dan 95.7 cm), dan rata -rata jumlah klorofil dari masing-masing perlakuan (29.07 mg/L, 29.74 mg/L, 33.55 mg/L, 31.79 mg/L, dan 36.33 mg/L).
