Research and development and social implementation of results will be carried out to address various issues centering on plant protection, such as increasing the risk of invasion of new pests and weeds from overseas, reducing the burden on the environment and workers associated with pest and weed control, and pest control in accordance with export partner country standards.

Development of a new selective medium to effectively isolate and distinguish bacterial leaf spot and leaf blight pathogens of cruciferous family
National Agriculture and Food Research Organization(NARO) has developed a selective medium for isolating pathogenic bacteria that cause seed-borne bacterial leaf spot and leaf blight disease, which is a major global problem in cruciferous vegetable production. This technology can be used as an accurate and efficient seed inspection method, contributing to the stable production of cruciferous vegetables and the export of vegetable seeds, which is an important industry in Japan.
Read MoreEstablishment of a pest control method using ultrasound for noctuid moths
National Agriculture and Food Research Organization (NARO) in collaboration with MEMS CORE Co., Ltd. and Kyoto Prefectural Agriculture, Forestry and Fisheries Technology Center has established a pest control method using ultrasound that repels moth pests. Many moths, including noctuid moths, escape the ultrasound generated by predatory bats to avoid being eaten by them. This research result is based on this behavioral maneuver. Therefore, it is possible to prevent noctuid moths from flying into crop fields for laying eggs by irradiating a wide area around the field with ultrasound. This can greatly reduce the number of insecticide applications for noctuid larvae that damage crops.

National Agriculture and Food Research Organization (NARO) in collaboration with Utsunomiya University and Kyoto University, has developed a statistical model to estimate allele frequencies in field populations by means of expressing the variation in the amount of DNA derived from each individual contained in the DNA sample extracted from multiple organisms at once as a probability. It is possible to accurately grasp the prevalence of drug-resistant pests and alien species with fewer inspections than individual diagnosis, by applying this result to genetic diagnostic techniques such as quantitative Polymerase Chain Reaction (PCR) and quantitative DNA sequencing.

The Agricultural and Food Business 28022C Consortium represented by National Agriculture and Food Research Organization (NARO) have established a new and practical control system ("wten"(dabuten*) pest control system) for spider mites, which are difficult-to-control pests on fruit trees, with natural enemies as core that can be used in greenhouse cultivation of grapes and oranges. This control system uses the appropriate application of biocontrol techniques such as conservation of indigenous natural enemies, and release of commercialized natural enemies. NARO created a Standard Operating Procedure (SOP) and published it on its website in order to promote the popularization of this control system.
Read More Prediction of 3D position of pests by modelling their flight pattern
National Agriculture and Food Research Organization (NARO) has developed a method to predict the pest flight position. This method can detect the three-dimensional position of flying pests from the image captured by the camera and predicts its movement. It is expected that this research result will contribute to the development of a new pest control system to exterminate pests, such as irradiating a high-power laser at the predicted position.
Read MoreDevelopment of new detection and identification technology for Diaporthe destruens
National Agriculture and Food Research Organization (NARO) has developed a new technology to detect and identify Diaporthe destruens causing foot rot disease of sweet potatoes. It is possible to distinguish and identify a related fungal species of the
Diaporthe batatas that causes dry rot disease of sweet potatoes. In recent years, the outbreak of foot rot disease has been confirmed and caused widespread damage in Japan. This newly developed technology has provided a quick and accurate diagnosis of foot rot disease. This contributes to prevention of widespread of damage caused by disease by means of quick and accurate diagnosis of foot rot disease.

A series of SOPs for fruit tree spider mite control system with natural enemies as core is published (apple edition / Japanese pear edition / fundamental & reference edition)
The Agricultural and Food Business 28022C Consortium represented by National Agriculture and Food Research Organization (NARO) have established a new practical pest control system of fruit trees with more effective use of natural enemies of spider mites. This control system is called "wten(dabuten)"* control system and uses the appropriate combination of two natural enemy utilization techniques such as conservation of indigenous natural enemies, and release of commercialized natural enemies. NARO has published three Standard Operating Procedures (SOPs) on NARO website to promote the popularization of this control system; the first SOP deals with explanations of the fundamentals, the second and third SOPs specialize in apple and pear production, respectively.
