Abstract

Control of root-rot of asparagus in asparagus fields

The root-rot of the asparagus causes serious, no more tolerable crop failures in the Upper Franconian the amount of sprouts/plants was obtained. Of course, of the damage was mainlyFusarium oxysporum, besides also isolatedFusarium culmorum andRhizoctonia violacea. A chemical control of this disease within asparagus fields is extremely difficult due to the deep-rooted plants. During experiments, Orthocid 50 (0,5 %) as well as Benomyl (0,1 %) were brought into the root area of the plants with a “dung lance”. By using this procedure, several years after the last Fungizid-application, a good result in reference to the produce and the amount of sprouts/plants was obtained. Of course, such an action should be considered as the last possibility of control, because experiences show that by means of proper cultivation actions, which already must be applied when planting new asparagus cultures, the occurrence of the root-rot of the asparagus can be reduced.
