In Brazil a mixture of fungicidas is applied

The U.S.A., today without problems, in alert

PUERTO IGUAZU, Missions. - In Brazil, where the disease managed to produce very important damages in Bay and I kill Grosso (306 and 131 million dollars, respectively, to affect between the 15 and 30% of the seeded area), the actions before the disease point at mixtures of triazoles and estrobirulinas.

According to Tadashi Yorinori, of Embrapa of Brazil, for all the country the cost of the application against roya is located in 576 million dollars. One is a number hardly superior to the value of the joint loss that the disease caused east year in Bay and I kill Grosso (about 470 million dollars).

In Paraguay, that has many problems in its Eastern zone of production, also good results with estrobirulinas are being observed and triazoles and, in addition, are tried to enable the producers. "it is taught to apply fungicidas when the disease is in the low part of the plant", Wilfrido Morel Paiva expressed, of the Regional Center of Agricultural Investigation.

Meanwhile, although still it does not register the disease, the United States it is prepared with a plan that includes monitoring tasks, investigations in genetics of varieties, validation of experiences of other countries as far as the use of fungicidas and seedtime of cultures trap to detect the presence of some espora of the pathogen of roya.

Still there is much discussion on how much it could delay in arriving the disease at that country, but some specialistic ones already say that with a hurricane that is transferred catching esporas from the zone of the Caribbean it would be enough to take esporas until the States of the South.

The projections also indicate that if roya Asian of the soybean enters that nation and causes damages that reach to 50% the possible losses would ascend to the 7200 million dollars. "My impression is that roya uses the North like a bridge to go to the south of the country. It is that in theory there are favorable climatic conditions during practically all the summer in humid Pampas ", indicated Antonio Ivancovich, technician of the INTA Parchment and coordinator of a program of roya of the soybean. "Anyway the incognito is how much it will take in entering in the sojera zone. It is time question; it is spoken of less than five years and can be one, two, three or four ", it added the specialist.
