Efficiency of tachigaren (active compound: hymexazole) against Aphanomyces root rot of sugar beet
1990
Ahrens, W. (Fachhochschule Weihenstephan (Germany, F.R.))
Climatic chamber trials with sugarbeet seed, differently pelleted with Tachigaren (active compounds: 70 per cent hymexazole), satisfactorily explained differences in Tachigaren effectiveness, which occurred in field trials. Tachigaren has a persistency of about three weeks. But when sown in a warm thoroughly soaked soil, plant losses increase when those conditions, favouring Aphanomyces black-leg, continue as it arise already eight days earlier in the Tachigaren-free pelleted seed. - A delayed emergence of one to two days occurs only at low soil temperatures. This is caused by shortening and thickening of the hypocotyle. In disease-free soil, 40 days after sowing at the latest, the initial differences in emergence are compensated
