Reduces 30-68% of rice black bug (RBB) population in seven days preventing yield loss of 80% due to bug burn. Microbial pathogen attacking RBB with its green toxin-producing spores that paralyze the pests then kill them. Economical, easy to mass produce using locally available substrates, and environment-friendly.

The PhilRice`s Rice Technology Bulletin No. 44 Metarhizium: Microbial Control Agent for Rice Black Bug provides a step-by-step on how to mass produce the fungus and how to apply it in the field.

Good alternative to commercial fertilizers for vegetables, upland rice, and corn helping farmers save on production cost while causing no harm to humans and environment. Reduces fertilizer use up to 80%. Provides plant resistance to diseases.

The how-tos in VAM production and application are discussed in PhilRice`s Rice Technology Bulletin No. 61 Biofertilizer Production: Vesicular Arbuscular Mycorrhizae (VAM).


Philippine Rice Research Institute (PhilRice) is a government corporate entity attached to the Department of Agriculture created through Executive Order 1061 on 5 November 1985 (as amended) to help develop high-yielding and cost-reducing technologies so farmers can produce enough rice for all Filipinos.
