Tomat merupakan salah satu komoditas hortikultura yang mempunyai nilai ekonomi yang tinggi serta mengandung zat-zat yang bermanfaat bagi tubuh manusia seperti vitamin C, vitamin A dan mineral. Dewasa ini produksi tomat mengalami penurunan akibat serangan penyakit layu Fusarium yang ditandai dengan pucatnya tulang-tulang daun, terutama daun-daun sebelah atas dan terkadang daun sebelah bawah. Penyakit ini disebabkan oleh patogen Fusarium oxysporum f.sp lycopersici. Pertumbuhan dan perkembangan patogen ini perlu dikendalikan secara efektif dan efisien. Salah satu upaya yang dapat dilakukan yaitu dengan menggunakan senyawa kimia yang berasal dari tumbuhan, yaitu daun sirsak, nimba dan cengkeh dengan berbagai dosis. Dimana daun tersebut mengandung senyawa yang bisa menghambat pertumbuhan dan perkembangan patogen Fusarium oxysporum. Penelitian ini menggunakan Rancangan Acak Lengkap pola Faktorial dengan 12 perlakuan. Hasil penelitian menunjukkan bahwa jenis fungisida nabati tepung daun nimba dengan dosis 50 g/polibag bisa menghambat pertumbuhan dan perkembangan Fusarium.
