THE City Government told proponents of the controversial Bacillus thurigiensis eggplant or the ”Bt talong” to make things clear first before they could run the second round of testing they are mulling. Leonardo Avila III, acting chief of the City Agriculturist Office, said the City Government in general did not change its stance in opposing the open field test of Bt talong in any parts of the city, even inside the University of the Philippines in Mindanao, in Mintal, this city. The UP Los Baños as well as the UPMin along with funding agencies are the proponents of the introduction of Bt talong in Davao City.
