Growing safe vegetables with biological pesticides
The Institute of Agricultural Environment has just completed a model for using a number of new generation biological pesticides with the advantages of wide spectrum of action, fast effectiveness and stable efficiency to control pests in safe vegetable production.
The above mentioned products include V-Bt; Matrine and Azadirachtin to kill armyworms, silkworms, and green worms; Azadirachtin and Abamectin to kill thrips and aphids; Abamectin + mineral oil and Matrine to kill flea beetles, leaf miners, and tomato and bean fruit borers.

When sprayed in the appropriate temperature range of 25 - 30 degrees Celsius, the insecticide's effectiveness is significantly higher than when sprayed in low temperature conditions (10 - 15 degrees Celsius); when air humidity increases gradually from 60% to 90%, the effectiveness of the insecticide also increases.
After 3 years of implementation, the project has produced 31 types of safe vegetables on a scale of 70.5 hectares in Hanoi, Hai Duong and Vinh Phuc, providing the market with over 1,741 tons of clean vegetables and fruits. The amount of pesticides used is much lower than the control production model and can replace 65-75% of chemical pesticides. Fertilizer and labor costs are reduced.
Product quality is guaranteed because it does not contain pesticide residues, so the high price brings economic efficiency to farmers.
