THERE are plants that emit what scientists call semio chemicals that could be used to control or prevent pest infestation in farming. These semio chemicals include repellents, attractants and hormones.

According to Dr. Susan F. Calumpang of UP Los Baรฑos whom we met at the UPLB-Media TechKnow Talks recently, one endemic plant that has potential for controlling green leafhopper in rice is the wild ginger locally known as Tagbak and botanically called Kolowratia elegans. This emits an odor that repels the green leafhopper which is the principal vector or carrier of the tungro virus disease in rice. Tungro is a major problem in rice farming.

Dr. Calumpang specializes in chemical ecology which is the study of chemicals that affect insect behavior. She is a member of the UP College of Agriculture’s Crop Protection Cluster and assistant to the UPLB Vice Chancellor for Research and Extension. Her studies could eventually result in the development of pest control products derived from plants and techniques that can be used in place of conventional chemical pesticides.

By the way, the “4 Easy Ways To Reduce Insecticide Residues In Veggies We Cook” that we posted in this blog on October 3, 2016 was based on the study of a team led by Dr.Calumpang. Did you know that the next day, October 4, there were 3,985 pageviews in our blog and out of this number, 2,851 were viewers of Dr. Calumpang’s 4 Easy Ways?
