Рекомендуется контролировать грибковые заболевания в культурах мелкого урожая

“The most important agronomic recommendation at this time is not to delay fungicide applications when diseases appear that could compromise barley and wheat yields,” says consultant Agustín Bilbao, in southern Buenos Aires. He notes that barley scald has appeared in recent days, with low incidence so far, but that it can dry out the leaves if not controlled in time. “Net blotch has also developed, affecting 70-100% of fields, with severe attacks in some cases. ”Wheat has suffered attacks of leaf rust, stripe rust, and yellow blotch, requiring a first application and with a second application imminent," he warns. “In northern Buenos Aires, advisor Julio Lieutier says that ”wheat suffered attacks of rust and that these days there is a wave of yellow spot that is being controlled chemically by airplane. Net blotch appeared in barley, which already required one application and is now undergoing a second. There have been developments in the products used to control these diseases, and today there are mixtures that offer effective control and long-lasting effects. "Beyond this situation, the overall condition of wheat is very good in the northern and southern subregions, although there are problems in the center of the province of Buenos Aires, where many hectares have been lost due to waterlogging. In northern Buenos Aires, crops developed very good tillering, some plots were re-fertilized with nitrogen, and there were very few instances of temporary waterlogging. In the south, wheat crops have two nodes and are looking to stem, and barley crops are reaching the flag leaf stage, also with very good biomass development. The marketing of the fine crop shows two different behaviors: on the one hand, there are producers who are committing part of their expected production at a fixed price to avoid the seasonal decline as harvest time approaches; on the other hand, there are those who prefer to wait, as a safeguard against the current political and economic uncertainty. For feed barley, USD 180 per ton is being offered for January in southern Buenos Aires, according to Alejandro Vejrup, manager of the Alfa cooperative in Tres Arroyos. For malting barley, prices rise to USD 200-210.
