In order to produce safe vegetables, the above-mentioned production regions have grown vegetables in four safe basic conditions of soil, water, fertilizer and insecticide. During the past time, the use of biological insecticide was particularly as effective as the chemical one so the farmers have been encouraged to use the bio-insecticide instead of the chemical one. The interest difference between this model and normal average ones is VND 302,000 per hectare and as high as VND 738,000 per 1,000 square meters in Bien Hoa City.
