Abstract

Cagayan Valley, which includes Isabela, Cagayan and Nueva Vizcaya, is one of the leading corn producing regions of the country. In 1999 it led the whole country in terms of total corn production. Now, this increase in yield from improved production techniques and the use of Bt corn is gravely threatened by the new corn plant hopper pest, Stenocranus pacificus Kirkaldy. As of last year, this new pest has been monitored in Jones and Echague, Isabela and at Tauo, Cagayan. As of this year, two towns in Nueva Vizcaya and eleven towns in Isabela are invaded. Lessons learned from the 2004 invasion in Mindanao by this pest have been utilized. The BPI thru the Crop Protection Division, the Crop Protection Cluster of UP Los Baños thru the National crop Protection Center (NCPC) and Monsanto Inc. are actively assisting the DA RFU 2 to combat this pest. Surveillance and pest management outreach programs are being extended to local government units.
