Plant rotation as a means of controlling wilt disease of Lupinus luteus L. on the basis of mycological investigations

Wanda Truszkowska

Abstract


Having observed in 1969 an epidemic of Fusarium wilt disease of lupin, the communities of fungi occurring in a given cultivated soil were examined. In the years 1970-72, the numbers of the Fusarium oxysporum f.sp. lupini population were found to change, in the others under the influence of lupin having been cultivated in the following crop rotations : 1) rye, potatoes, oats or 2) rye, maize, oats. Provoking changes in the qualitative and quantitative composition of the fungal populations in cultivated soil by means of different cultivated plants, with the aim of altering the conditions of the pathogen, should be practised in order to protect the lupin crops against Fusariuni wilt disease.
