Biological control of weeds

Tjitrosemito Soekisman, . (2013) Biological control of weeds. [Proceedings Paper]

The establishment of oil palm plantation in Indonesia had been widely extensive and predicted due to the increasing demand of palm oil and the area harvested will reach 20.4 M ha in 2050. It is fantastically huge in area therefore it is imperative to utilise the area efficiently in terms of space time and labour as well as other capital fund in environmentallyfriendly way. Good agricultural practices must become the basic activities particularly integrated weed management approach that emphasizes the use of biological control mean to control weeds. Classical biological control has been the matching natural enemies with introduced weeds and the practices have given good results such as in the case of Salvinia molesta or prickly pears. The converted solar radiation into plant biomass however benefits only to arthropods would have been more efficient for human interest if it can benefit directly by human being. The utilisation of grass carp to control water hyacinth for example will provide fish for people in the surrounding lakes weeds under the canopy of established oil palm can be utilised to raise livestock converting weed biomass into meat. It is advocated that whenever possible to utilise animals that benefits human being directly.

Abstract

The establishment of oil palm plantation in Indonesia had been widely extensive and predicted due to the increasing demand of palm oil and the area harvested will reach 20.4 M ha in 2050. It is fantastically huge in area therefore it is imperative to utilise the area efficiently in terms of space time and labour as well as other capital fund in environmentallyfriendly way. Good agricultural practices must become the basic activities particularly integrated weed management approach that emphasizes the use of biological control mean to control weeds. Classical biological control has been the matching natural enemies with introduced weeds and the practices have given good results such as in the case of Salvinia molesta or prickly pears. The converted solar radiation into plant biomass however benefits only to arthropods would have been more efficient for human interest if it can benefit directly by human being. The utilisation of grass carp to control water hyacinth for example will provide fish for people in the surrounding lakes weeds under the canopy of established oil palm can be utilised to raise livestock converting weed biomass into meat. It is advocated that whenever possible to utilise animals that benefits human being directly. Of course weed such as Chromolaena odorata which is not edible shall be controlled by its natural enemies such Cecidochares conexa or Pareuchaetes pseudo insulata but grasses and palatable weeds such as Asystasia micrantha may be better to feed livestocks.
