New Release of 'Suzumidori Neo': A Transpiration-Activating Material Protecting Crops from Extreme Heat

PhytoChrome, Inc. (Shinjuku, Tokyo; Representative Director: Keisuke Uchida) will launch 'Suzumidori Neo,' a transpiration-type biostimulant product that enhances plant heat tolerance by activating transpiration, on July 1, 2026.

While carrying on the technology of 'Suzumidori,' which received the Japan Society for Bioscience, Biotechnology, and Agrochemistry Award in 2019, the device has been redesigned from a conventional tag type to a 'plate type' to pursue ease of use in the field. The new device, which starts by simply snapping it, significantly improves convenience in agricultural settings.

Background: Serious Crop Damage from Extreme Heat Summer temperatures have risen in recent years, leading to an increase in damage such as muggy seedlings, wilting, and quality degradation nationwide. In greenhouse horticulture and open-field cultivation, in particular, reduced transpiration due to stomatal closure has become a cause of poor growth, making the 'strengthening of high-temperature countermeasures' an urgent issue for producers.

About the New Product 'Suzumidori Neo' 'Suzumidori Neo' is a biostimulant product equipped with the company's proprietary transpiration activation technology, in which the plant leaf component '2-hexenal' opens stomata to promote transpiration.

Features of the New Device - Simple Start with a 'Snap': Internal structure optimized so that simply snapping it begins the diffusion of active ingredients, significantly reducing work time compared to previous models. - Equipped with a Replacement Indicator: Visibility of the usage period prevents forgetting to replace and supports stable effect delivery. - Improved Handling with Plate Type: Easy to hang and fix, evolving into a shape that is easy to use in both facilities and open fields.

Product Overview - Product Name: Suzumidori Neo - Content: 10 packs (for 10 ares) - Period of Use: Approx. 3 months - Price: 6,050 JPY (tax included) - Release Date: July 1, 2026 - Distribution: Sequential rollout, primarily through existing distributors.

Future Developments Starting with the release of 'Suzumidori Neo,' the company will strengthen its comprehensive high-temperature countermeasure solutions by combining biostimulant product groups, such as the high-temperature countermeasure material 'Heat Impact' and microbial material 'N-Catch.'
