Weeding Treatment CangkulTangkil (cangkul kecil)Bajak singkal Harrow Herbisida

Manage of Pest and Diseases

• ORGANISME PENGGANGGU TANAMAN Binatang, serangga, jamur, bakteri

• PENGENDALIAN PREVENTIF : - Tanam saat kondisi lingkungan tidak menguntungkanOPT - Rotasi Tanaman - Penanaman lebih dari 2 tanaman (avoid monoculture) : > meningkatkan jumlah organisme > sbg tanaman repellent - Penggunaan mulsa plastik hitam perak

Hindari monokulturTerapkan Intercropping

Rotasi Tanaman

Mekanis (habitat, sex feromon trap, yellow stiky trap)

Pengendalian hama secara biologis yakni pengendalian hama dengan menggunakan/memanfaatkan musuh alami/predator

Pada tanaman kubis : predator Plutela adalah Bacillus thuringiensis, Diadegma sp

Biologis

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.
