9 Hindari monokultur Terapkan Intercropping Rotasi Tanaman

11 Pengendalian hama secara biologis yakni pengendalian hama dengan menggunakan/memanfaatk an musuh alami/predator Pada tanaman kubis : predator Plutela adalah Bacillus thuringiensis, Diadegma sp Biologis

12 Natural control of leaf folders Numerous natural enemies 46% eggs eaten by predators 18% eggs parasitized Many larval parasites and generalists predators © KLH 2002

13 Generalist predators Generalists predators, like spiders, crickets, beetles live in perennial habitats surrounding rice fields. KLH

14 Parasitoids There are > 400 species of hymenopteran parasitoids in rice based ecosystems Most of them are highly host specific. Their unique roles may not be easily substituted. Example. Rice bug egg parasitoid, Gryon nixoni. KLH

15 Understanding the rice landscape… …Integrated Pest Management (IPM)

17 PESTISIDE AND SPRAYING Kimia = Pestisida - Insektisida - Fungisida - Nematisida Aplikasi pestisida harus dilakukan dengan seksama - Pestisida = racun - Gunakan sesuai kegunaan - Gunakan sesuai dosis - Pahami perilaku hama/penyakit - Resistensi - Lakukan dengan aman (pakaian, masker, arah angin, dll)

18 Equipment in Pest and Diseases Spraying Power Sprayer Knapsack Sprayer

19 Boom Sprayer

20 …a success story in Vietnam Reducing pesticide use…

21 In Vietnam, based on decades of ecological research in rice fields, we found spraying during the first 40 days after sowing was not necessary. So, farmers were motivated through an innovative communi- cation campaign.
