Growing safe vegetables with biological pesticides.

The Institute of Agricultural Environment has just completed a model for using several new-generation biological pesticides with the advantages of broad spectrum of action, rapid efficacy, and stable effectiveness to control pests in safe vegetable production.

The aforementioned preparations include V-Bt; Matrine and Azadirachtin for controlling diamondback moth, cabbage worm, and green caterpillar; Azadirachtin and Abamectin for controlling thrips and aphids; Abamectin + mineral oil and Matrine for controlling flea beetles, leaf miners, and tomato and bean fruit borers.

When sprayed at the appropriate temperature range of 25-30 degrees Celsius, the effectiveness of pesticides is significantly higher than when sprayed at lower temperatures (10-15 degrees Celsius); as air humidity gradually increases from 60% to 90%, the effectiveness of the pesticides also increases.

After three years of implementation, the project has now produced 31 types of safe vegetables on a scale of 70.5 hectares in Hanoi, Hai Duong, and Vinh Phuc, supplying the market with over 1,741 tons of clean produce. The amount of pesticides used is significantly lower than in the control group and can replace 65-75% of chemical pesticides. Fertilizer and labor costs have also decreased.

The product's quality is guaranteed because it contains no pesticide residue, resulting in a higher price and greater economic benefits for farmers.
