The resistant mushroom puts the banana producers on guard
Ecuadornews:

The problems of multiresistant black sigatoka (fungi) and soil acidification (by synthetic fertilization) in banana plantations in Ecuador are not common, but this does not mean that isolated cases are occurring. What puts the producer on guard
The two topics were analyzed at the World Banana Summit, an event that takes place in Guayaquil.
Dr. Mario Orozco, of the National Institute of Agricultural and Livestock Forestry Research of Mexico, explained to Diario EXPRESO that the black sigatoka plague is about 50 years old on the continent, but it is still the number one problem that affects the production of bananas.
The problem is uphill when the fungus becomes multiresistant, but there are already molecules to fight it. “The countries that have the biggest problem with this are Costa Rica, Colombia and Panama, because they have climates that favor it, which is rain all year round. In Ecuador it is less, because it is dry tropic, although some cases of multiresistant black sigatoka have been found “.
The expert added that the producer should not buy a chemical to kill the fungus, without a prior examination of the situation on the farm. He announced that new molecules are being studied to attack multiresistant fungi, which will be on the market in a short time.
Regarding soil acidification, by synthetic fertilization, Dr. Egbert Spaans, of the Netherlands, indicated that in November of last year they found isolated cases of this problem in Ecuador. “The novelty is that it was thought that these cases could not occur in Ecuador, because the land here is very rich in calcium and magnesium. But it has been seen that they are not exempt from the problem. “
The acidification of the soil prevents the healthy growth of the roots of the plant and the solution is to apply agricultural lime.
The positive thing in the two topics is that they are not extended in the banana plantations of the country, therefore the prevention will allow Ecuador to continue being an important exporter of the fruit to the world.
The drone to spray
The megadron, which in the Ecuadorian market costs 25,000 dollars, is used to fumigate in the day and in the night. It can be located three meters above the plant. (I)
