EFFECT OF CHEMICAL TREATMENT OF SEEDS ON THE HEALTHINESS OF ASPARAGUS SEEDS AND CROWNS

The effects of 11 chemicals in different combinations used for seed dressing on the occurrence of pathogenic fungi on asparagus seeds and infestation of one-year-old crowns by Fusarium were evaluated over a period of four years.

Fungi of the genus Fusarium contaminated 3–7 percent of untreated seeds.
Fusaria were not isolated from seeds treated with benomyl in acetone and with triadimenol + imazalil + fuberidazol in any of the four years of the experiment.
The latter chemical reduced seed germination rate by over 15 percent.

Seed dressing did not protect one-year-old crowns against infestation by Fusarium, although occurrence of root rot was slighty smaller when seeds had been treated with benomyl and carbendazim.
