Learning

The damage is a lot and we have been learning because there are things that one does not know. It is very important that you explain how to set the traps, the damage that these surrounding blackberries do, that you have to eliminate weeds, the fruits that remain on the plants. All of this must be applied because one wants to give people the best and because of ignorance sometimes we do things wrong ”.

The technical head of Prodesal San Clemente, Macarena Lillo and Fernando Durán, in charge of one of the 6 operating units of the commune, explained that the summer rains caused a complicated situation in many areas: “It was like a perfect storm, with high humidity Then the temperatures rose, with the rains they could not continue harvesting and there was a lot of fruit in the orchards as hosts and thus they reproduced more. There was a lot of damage because of what the intermediaries did not want to buy and the situation was very complicated, so it is important that the authorities come and that the farmers see that there is concern and that they have to prepare for the next season ”.
