In Paraguay
, the
recommendation is to water the plants daily with
small amount of
water. Any kind of
watering system can be used. However,the most recommended, but not the
most used, is the
leaking system wich offers the following advantages:
- The water is distributed
efficiently.
- Low use of energy.
- It is automatic.
- There is the possibility to make transplant in
any kind of land.
3) Fungi and plagues.
In rare occasions are
reported attacks by these agents.
- Fungus: The damage is
almost always minimum, therefore, it is not necessary the use ofchemical agents. In exceptional cases, when the
damage is significant, benomil and metil-tiofenate are used.
- Plagues: there has not
been any report about significant plague attack in the world. The use of chemical agents has not been
recommended in any case until the year 2009.
