Modern Biotechnology in agriculture has been done. As a new technology that uses the techniques of molecular biology and genetic engineering, able to manage plant health, optimize production and reduce pesticide use.
Specific to biotechnology, crop protection (Perlintan Biotech), is now experiencing rapid growth and provides many benefits in maintaining and increasing production. Biotech Perlintan consists of three main aspects, namely diagnosis or identification of plant pests (OPT), OPT interaction with the host plant and environment, as well as pest control.
Through molecular biology techniques, the pest can be identified and detected more accurately for the benefit of proper diagnosis and quick. "The techniques of molecular biology is very helpful in understanding the development of a disease infection in its host plant as well as the influence of environmental factors on the incidence, severity and spread of a pest attack," explained Prof. Dr. Ir Siti Subandiyah, at the Senate Hall, when inaugurated as Professor of the Faculty Agriculture UGM, Wednesday, June 23 last, in a written statement UGM, in Jakarta, Thursday, June 24.
In addition, also produced by genetic manipulation of natural enemies, antagonists bodies, and structure of biological communities resulting in biotic and abiotic environment are able to suppress the development of more effective pest.
"The most significant constraint on the production of fruits in the field is a pest problem. The problem of this pest is causing the decline of production in quality and quantity," he said.
According to Siti Subandiyah, various plant diseases previously unknown pathogen, because identity can not be isolated on artificial medium to be revealed by using molecular identification techniques.
Of investigating the sequence of DNA bases-the raw sequences (conserve), such as the 16S ribosome to the body of prokaryotic or eukaryotic ribosomal 18S to the body, Gena mikrosatetelit in bacteria and fungi, or Gena coat protein on the virus group, can be used to identify the bodies that can not be cultured in medium artificial.
Selection and assembly of species / cultivars of citrus in Indonesia, he said, should immediately be increased, especially with the ever-expanding HLB disease that is difficult to control.
Type / orange cultivars grow quickly with high fitness will be able to compete with the relatively slow development of Las in the host tissues.
"The combination of rootstock with oranges mandarin / tangerine as the stem of which was tested in vitro in Faperta rootstock GMU show there are more promising to replace the Rough Lemon rootstock type (RL) and Citrus Junos (CJ) who has always used in Indonesia, "he explained
