“…Using GFP-tagged KNB422 and DsRed2-tagged G. fujikuroi, it was observed that the two fungi occurred in the same part of the rice plant, 18) which indicates that they interact in the plant. erefore interaction between KNB422 and pathogens was examined.…”

“…Furthermore, KNB422 grows on rice seeds very rapidly and can also grow well in soil. 13,18) Moreover, the micro ora of the Kureha-soil is usually poor, 13) and, therefore, there may be an ecological niche for KNB422 to occupy the rhizosphere.…”

Talaromyces sp. KNB422, isolated from a rice seedling, is a fungus that is highly e ective against several rice seedling diseases. To clarify its mode of action, the interaction between KNB422 and Rhizopus oryzae, Pythium graminicola, and Gibberella fujikuroi was examined in vitro. In a PDA medium, KNB422 expanded its hyphae over the mycelia of the pathogens. e interaction between KNB422 and R. oryzae and P. graminicola was examined by scanning electron microscopy. e hyphae of KNB422 grew around and then penetrated the hyphae of the pathogens. Furthermore uorescence microscopy revealed that KNB422 grew toward, penetrated into and dissolved the G. fujikuroi hyphae. KNB422 has the ability to parasitize pathogens, such as R. oryzae, P. graminicola, and G. fujikuroi, to prevent their growth.

Non-chemical seed treatments include physical treatments, microbial treatments and treatments with other agents of natural origin like plant powders or extracts. Physical treatments with hot water, aerated steam, or dry heat have successfully been applied to a range of crops against a range of target pathogens and are in commercial use primarily for vegetable seeds. They can be very effective but need to be optimised on a per seed lot basis.Microbial seed treatments may control not only seed-borne pathogens but also provide some protection against pathogenic soil-borne inoculum. However, research on the use of micro-organisms as seed treatments has been limited, and there are only a few examples of commercial use. The latter is also true for botanical seed treatments, despite many reports of bactericidal and fungicidal effects of compounds from plants. The reason may be a lack of research on the one hand but mainly commercial constraints like development and registration costs in relation to market size.The current chapter gives an overview of approaches that have been taken to utilize the above-described non-chemical methods for control of important seedborne pathogens of vegetables and small grain cereals. The examples treated include bacterial (black rot of brassicas, pea bacterial blight, bacterial blotch of cucurbits, black chaff of cereals), fungal (Alternaria diseases of carrot, black leg of brassicas, common bunt of wheat, Fusarium seedling diseases of small grain cereals, the loose smuts of barley and wheat, fungal diseases of rice and sorghum) and important viral diseases.
