PhilRice seeks biocontrol vs worms
THE Philippine Rice Research Institute (PhilRice) has partnered with the Center for Agriculture and Biosciences International (CABI) in identifying a potential biocontrol agent that may help stave off infestations of fall armyworm (FAW).
Evelyn Valdez, PhilRice senior science research specialist, said their team has been monitoring FAW infestations in Cagayan Valley (Region 2), Central Luzon (Region 3) and Cordillera Autonomous Region. Samples of fungusinfected FAW were collected during their site monitoring.
“With our current knowledge gap regarding its effects on rice and rice-based farming systems in our country, we recognize the significant threat it poses to our food security. Given that farmers primarily resort to expensive and potentially harmful synthetic pesticides for control, exploring biocontrol methods emerges as a more sustainable solution,” Valdez said.
“We have requested the expertise of CABI to help identify a potential biocontrol agent. We will send them the samples for further analysis after we have isolated and assessed the specimens,” she added.
Previously, FAW primarily targeted corn, but it has now found its way to rice, infesting 18- to 28-day-old seedlings with the larvae feeding on the leaves. The first infestation in Cagayan spread in 13 municipalities.
The name “armyworm” comes from how these insects gather in large groups during the larval stage and can destroy large areas of crops. The Food and Agriculture Organization reported that some countries reported a yield loss ranging from 3 to 5 percent in 2020 and 2021 due to FAW infestation.
Feng Zhang, CABI regional director for East and South-East Asia, emphasized the need for collaborative research initiatives to address pest and disease challenges in agriculture.
“Addressing the challenges posed by emerging pests and diseases in rice cultivation demands united efforts. Only through collective action can we effectively safeguard rice production and ensure food security for communities worldwide,” he said.
