A substance called Biosafe extracted from natural ingredients has been successfully synthesized by Nha Trang University researchers. The substance has been effectively applied to several types of plants. This product won the consolation prize at the 9th Provincial Technical Innovation Contest (2020 - 2021).
According to Engineer Pham Dinh Van, Head of the researchers, to provide mango farmers with safer and more sustainable solutions, the group has conducted a research and successfully developed multi-functional Biosafe of natural origins. The product has been used in a sustainable way of farming, replacing partly or completely chemical pesticides on mango trees.

Biosafe has been also researched and successfully applied to chili, water melon and Cucumis melo in Ninh Hoa Town; pomelo in Dien Khanh District, avocado in Lam Dong Province, pepper in Dak Lak Province and Phu Yen Province; and Asparagus in Phu Yen Province.
Biosafe is synthesized from such main ingredients as extracts from biologically active substances from herbs, seaweed; calcium and micronutrients from eggshells; protein and nutrients from fish; potassium and micronutrients from plants.
The product is used to spray on leaves and roots of fruit trees or vegetables. The nutrients contained in the product are easily and quickly absorbed through roots or leaves; and biologically active substances protect plants from pests and diseases; enhancing health growth and boost yields.
The method is simple, cost-effective and affordable for farmers. The main ingredients of the product are completely of natural origin, so it is safe for users, environmentally friendly, meeting safety and sustainability standards in agriculture.
The researchers have applied the product to Australian mango trees grown on 2 farms, namely HoBoMo Farm in Tan Hung Village, Ninh Hung Commune; and Dozen’s Farm, DAFUTA Company, Ltd. in Buon Lac Village, Ninh Tay Commune in Ninh Hoa Town.
HoBoMo Farm, 50ha, has 8ha of or Australian mango or 2,000 trees. The control group receives conventional farming treatment while the experimental group is under the new farming method with the use of Biosafe replacing chemical pesticides and partly fertilizers.
The results show that the experimental group saves 30 - 40% of pesticide cost/ crop with higher yield, up 20 - 30%, higher fruit quality, up 10 - 20% compared with the control group. The research has been done on 50 Australian mango trees aged 6 - 7 of control group and experimental group with 25 trees/ group. Dozen’s Farm, 55.3ha, has mainly Australian mango trees, mostly aged 1 to 1.5. DAFUTA has signed a contract to buy Biosafe for use on the entire farm.
Engineer Pham Dinh Van said, “the research has expanded its scope to evaluate economic and technical efficiency of Biosafe with the hope that Biosafe will be used widely, improving efficiency and productivity in agriculture."
