Marcelo, I’ve a load of wheat in harvest and I am beginning to see yellow rust pustules (incidence lower than 5%). Is using azoxystrobin + cypyroconazole advisable at this phenological stage?
Reply from Marcelo Carmona: Marcelo, since it’s a comparatively new selection, because of the excessive variability of the pathogen and the collapse of some genotypes, it’s essential to ask the seedbed how it’s at the moment behaving for this 12 months 2023. In any case, this rust may be combated in inclined varieties from tillering till the beginning of grain filling.
Mixtures of strobilurins and triazole are nonetheless efficient in opposition to yellow rust if utilized in a well timed method. Within the occasion that yellow spots (together with yellow rust) additionally happen in portions that require utility (15-20% leaf infestation), it’s endorsed to make use of efficient triazoles (cyproconazole shouldn’t be more practical on this space) and, if crucial, broad-spectrum mixtures -Carboxamides (in opposition to rust and stains), as strobirulins don’t work on yellow stains both.
