In a conference aimed to no-tillage farmers in Rosario, northeastern Argentina, Federico Massoni, an agronomist at Argentina’s National Institute of Agricultural Technology (INTA), has alerted for the challenges that the new corn crop (2016/2017) will present as Argentine farmers get back to corn with the elimination of export taxes. For Massoni, a lot of producers have been negligent with Bt corn varieties.
“We have to be very serious about the refuge areas. In Brazil, they have played with it and the result was very terrible. With the massive comeback of corn, we can see a widespread Spodoptera if we play with it and don’t do refuge areas as it has been made recently,” alerted Massoni.
Aníbal Cerrudo, an expert from the same institution, declared that the investment on chemical control needs to comeback. “Now that the government got out of the way, the farmers have the ball and need to invest on chemical control. Recently, they did not do it, but the changes of possible profitability may make the difference. Let’s remind that the La Niña will be strong,” said Cerrudo.
The southern-most state in Brazil is Rio Grande do Sul and it is also the last state to finish the soybean harvest in the country. The works have now reached nearly 20 percent of the planted surface with higher than usual yields. According to local agronomists, the harvest tends to go faster in the coming weeks because of forecasts of favorable weather. In some areas, there are a few reports of Asian Rust, but not enough to tell any significant losses.
The soybean grower Naildo Lopes who farms at Nova Mutum, North of Mato Grosso, and advises owner of nearly 99,000 acres in the region said to AgroSouth News that there is a big danger of losses originated from the Soybean Looper and the Whitefly. Nova Mutum just had slightly over two inches of rain in the last 20 days. “If the weather continues like this, we will see more problems with the Looper and the Whitefly combined with fungus and the Asian Rust. It is not worthy to do any control if your neighbor is not doing it. The losses can be greater than they already are,” Lopes told. The Mato Grosso Institute of Agricultural Economics already reduced the crop projection for the state in over one million tons.
The second biggest soybean producing state of Brazil, Paraná, has banned the planting of the second soybean crop through an ordinance published yesterday. The goal of the measure is to curb the proliferation of the Asian Rust over the crops. The punishments for those who break the norm start with a warning, can become a fine and, if it is repeatedly, the destruction of the crops.
Farmers from the Brazilian state of Paraná, the second biggest soybean producing state in the country, have manifested worries about a legislation that is likely to ban the planting of the second soybean crop. The law that is being discussed in the state proposes the prohibition to avoid the dissemination of the Asian Rust, after some Embrapa studies were released revealing that the lack of rotation was the reason for the outbreak. The fallowing in Paraná currently starts in June 15 and goes until September 15, but the government intends to anticipate it to May. According to some local cooperative unions, that would reduce the cost of application of some fungicides. Farmer Nelson Bortoli, on the other hand, said that a lot of municipalities in Paraná depend on the income coming from the second soybean crop.
The Association of Soybean Growers of Mato Grosso (Aprosoja) has made a new alert on the likely propagation of the Asian Rust during the 2015/16 crop in that state. The situation was identified as more extreme in the regions of Sinop, Vera, Cláudia, and Campo Novo dos Parecis. “The rainy period was sufficient to make the soybean germinate. We have found some recently germinated soy and plants in full grain filling in the west of the state. This should not be happening at this time,” says agronomist Eduardo Vaz in an statement of the entity.
According to some experts, Rust may be coming from Paraguay and Bolivia, taken by the wind. “In Bolivia, they start to plant in July or August. The Rust comes there firstly and also bring it here before [what is expected]. Allied with the winds from the South, this can compromise the production in Mato Grosso. We recommended double attention,” adds the statement.
The planting of the summer season of corn has already started in the state of Paraná in southern Brazil. Farmers covered 14 percent of the total surface of approximately one million acres. Local agronomists say that weather conditions have been favorable and the crop has developed well. In the meantime, 96 percent of the second corn crop was harvested in the state.
The Mato Grosso Institute of Agricultural Economics (Imea) released data that reveals that the expenditures with herbicides account for 12 percent of the total cost for soybean growers in the Brazilian state of Mato Grosso. The number jumped from eight percent in 2010. The institute says that in the last five years the cost has increased because of a higher use of glyphosate to fight weeds.
On Corn, the costs with herbicides jumped from five to 10 percent of the crop. Another issue pointed out by Imea is the lack of product rotation and the use of RR technology. “Having a soil coverage permanently reduces the incidence of weeds. When a producer adopts the right management, he/she reduces the problem of weeds on population quantity as well as individual resistance,” said Embrapa researcher Dionísio Gazziero in a reporter signed by Leonardo Gottems at news portal Agrolink.
Torrential rains have delayed the second corn crop harvest in several state of Brazil. In the case of Mato Grosso do Sul, according to the local Association of Corn and Soybean growers, the harvest reached 12.4 percent of the 4.04 million acres planted. Compared to the average of the previous years, there is a delay of nearly seven percent. But, according to local agronomists, the rains and frosts in that state did not affect yields yet and have not generated losses.
Floods and torrential rains have affected the southern states of Brazil in the last few days generated concern over wheat areas. In some areas of Rio Grande do Sul, the southern most state, relative air humidity reached 100%. The accumulated volume of rains is 20 percent above average for the state. According to experts, the wheat crops are relatively well because they are at the vegetative stage. No signs of diseases were reported yet, but worries remains.
In the case of Paraná, some parts of the crop are at the flowering stage and the rains are three times above the normal for the period. The percentage of the wheat areas considered in good conditions fell from 94 percent to 90 percent, according to official data.
