Studies to reduce the Fusarium inoculum to avoid Fusarium ear infections in cereals applying alternative substances (Part II) (FUSAStop II)
Project
Project code: JKI-A-08-1303
Contract period: 01.04.2021
- 31.01.2022
Purpose of research: Applied research
The occurrence of numerous Fusarium species often leads to plant damage in various crops and is associated with the formation of mycotoxins in the plant tissue. In addition to damage to yields, this also results in qualitative losses and considerably limits both the use for human nutrition and for animal use. Control can only be achieved through an integrated strategy, taking into account the influencing factors of prevoius crop, crop rotation, tillage, choice of variety, inoculum density, weather and use of fungicides.
In order to minimize the risk potential at the risk locations, attempts are being made to significantly reduce the inoculum. Here it is important to treat the organic material present on the surface of the soil and contaminated with fusarium fungi in such a way that fungal growth is largely inhibited and the reproduction and formation of fruiting bodies with flyable ascospores / conidia is prevented. Saline solutions such as magnesium chloride, potassium iodide, zinc oxide and other “low risk” substances are to be investigated as test substances. For these substances, an effect on spore germination and possibly on the formation of spores is described in the literature.
The first studies will investigate the effectiveness of these low risk products against Fusarium species in an in vitro screening process. The effectiveness against numerous Fusarium species that occur on cereals and maize is determined. The inhibition of mycelial growth and spore germination are used as measurement parameters. In addition, the influence of the substances on mycotoxin formation (deoxynivalenol, zearalenone, fumonisin) in the medium is to be investigated.These investigations are intended to carry out surveys of fungal growth and sporulation on the corn stubble, as well as to control the Fusarium sp. included in the wheat ear.
