PCAARRD Addresses Witch Broom’s Disease in Cassava

Media Release:

CASSAVA Phytoplasma Disease or CPD, also known as ‘Witch Broom’s Disease,’ is a type of virus, which stunts cassava plant growth and development. It becomes a serious threat to cassava industry if symptoms appear as early as two to three months, as all plants may die.

A newly-funded project is expected to address the problem of EDCOR Development Cooperative (EDCOR) on CPD. EDCOR, one of the big producers of cassava in San Guillermo, Isabela, supplies cassava to one of the leading corporations in the country through the plantations of its 237 members.

However, the municipal agriculture office reports that in 2018, total cassava sales dropped from Php2.1 million in 2017 to only around Php768,000. Production area likewise dropped from 1,170 hectares in 2017 to only 513 hectares in 2018.

EDCOR General Manager Daniel Medina and Chairman of the Board Honorio Sanchez attribute the poor performance of cassava production to disease infection. However, EDCOR needs the ability and the mechanism to recognize and monitor the disease in their plantation and the information on disease management protocols.

The project will design, develop, establish, and implement an embedded system for smart detection, recognition, and mapping of CPD using Aerial Unmanned Vehicle (AUV) and deep learning technology. The latter is applied to image processing and recognition. This project will be implemented for two years by the Isabela State University (ISU) in partnership with EDCOR Development Cooperative.

According to project leader Dr. Irma T. Plata of ISU, the project will tap two platforms to monitor CPD-infected plantations: the CPD web-based monitoring system and the CPD-mobile based monitoring app. These platforms will provide and disseminate data, information, monitoring results, and reports related to cassava infected areas to EDCOR cassava farmers, community, and stakeholders.

Specifically, the information system and services will include among others: data, maps, and specific locations of cassava plantation infected by CPD; photos from the actual field; estimated possible loss of production and yields; SMS notifications to farmers; and experts recommendations and management options for farmers to consider and or adopt.

Moreover, with the system, early detection of the disease is possible by using and analyzing the results of the CPD pattern analysis.

“This partnership is very good, and this is what we need. This is the partnership that we should be engaging in. We should not do research for the sake of research, without a definite taker of the technology,” said ISU President Dr. Ricmar P. Aquino during the recently held project inception meeting at ISU, Echague, Isabela.

Dr. Aquino acknowledged the funding support from the Department of Science and Technology (DOST) through its Collaborative Research and Development to Leverage Philippines Economy (CRADLE) Program.  He also thanked DOST’s Philippine Council for Agriculture, Aquatic and Natural Resources Research and Development (PCAARRD) for the opportunity and trust in ISU’s capability.

PCAARRD, through its Agricultural Resources Management Research Division (ARMRD), will supervise, monitor, and evaluate the project. ARMRD Director Dr. Juanito T. Batalon, during the meeting, expressed trust in ISU’s ability to deliver the commitments and expected outputs of the project. He encouraged cooperation between and among agencies and partners who are involved in the project.

CLSU and Cobb-Vantress Phils, Inc. Collaborate for CRADLE-supported Project

CENTRAL Luzon State University’s (CLSU) and Cobb-Vantress Philippines, Incorporated are collaborating on a project to develop “Machinery for Decontaminating Rice Hull as Litter Floor for Broiler Breeder Production.”

This project is funded through the Collaborative Research and Development to Leverage Philippines Economy (CRADLE) Program of the Department of Science and Technology (DOST).

CRADLE is one of the components of the DOST’s Science for Change Program, which aims to create a synergistic relationship between the academe and industry in terms of research and development (R&D). The industry identifies the problem that needs solution and the academe conducts the necessary R&D to solve the problem.

During the project inception meeting organized by DOST’s Philippine Council for Agriculture, Aquatic and Natural Resources Research and Development (DOST-PCAARRD), project leader Dr. Marvin M. Cinense presented Cobb Vantress and CLSU’s joint effort in packaging the project.

As a supplier of breeding stock for major integrators in the Philippines, Cobb-Vantress targets to produce 2.0 million parent stock every year. To attain this target, it needs enormous amounts of rice hulls as litter material for chickens in scratching and mating area.

The company needs 3,500 to 4,000 bags/month at 10-12 kilogram per bag. During rainy season, supply of these materials is inadequate, leaving them the option to store the materials while supply is high. However, the stored materials encounter contamination issues. The contamination of litter materials may lead to poor performance and health risk to their stocks.

In response to this problem, CLSU’s project will design and fabricate a decontaminating machine with four parts: rice hull cleaner, decontaminating/mixing machine, dryer, and bagger. The research team will evaluate machinery’s performance and the litter materials after decontamination.

PCAARRD through its Agricultural Resources Management Research Division (ARMRD) will monitor and evaluate the implementation of the project. Dr. Batalon, expressed hopes that this two-year project will answer the problems and needs of the industry. (DOST-PCAARRD S&T Media Service)
