Dong Nai applies biotechnology for plant conservation.

Trang Dai safe vegetable

According to the research, while biological medicines of plant conversation are less poisonous with human and cattle, they are rapidly destroyed in natural environment; short isolated time; high-selectivity; less harmful to useful creatures on fields; strong effects, low active elements; simple processing… During last time, Dong Nai Bureau of Plant Conversion has applied some effective biotechnologies which are models of integrated pest management (IPM) in rice cultivating. The model is prominent in limitation of using chemical medicines, preserve of useful creatures on the field to control pests. Moreover, applying the models limited pest’s effects, contributed to decrease cost of plant conservation medicines, ensure productivity, bring economic effects to rice farmers. Especially, Dong Nai also carries out production of safe vegetable according to IPM process that uses biological pesticides when the epidemic occurs to make safe products for consumers. Until now, Trang Dai Safe Vegetable has been issued certificate of brand name by Bureau of Intellectual Property. At the present time, this model has been conducting on the other plants such as durian, segment fruits and pepper.

To epidemics, which cause damage to plant’s productivity and happen frequently, many areas use biological medicines of plant and insect conservation to prevent. This limits using chemical medicines, save health of human and environment. Some products used on a large scale are Trechoderma for preventing root’s damage to durian, segment fruits, and pepper. Bemetent is a product which is made from insect mixture well to treat beetle (got 83.18 to 98.84 percent after spraying 2 to 5 times). Bureau of Plant Conservation encourages farmers in using this product in rainy season to treat beetle harmed to grapefruit instead of chemical medicines. In using insect for prevention, Dong Nai Bureau of Plant Conservation conducts multi-breeding of parasitic bees-Asecodides hispinarum to kill effectively beetle harmed to coconut and bonsai.

Use biological medicines of plant conservation for preventing pests on grapefruit.

Until now, farmers has used chemical medicines to prevent pest which is very popular in grapefruit garden with high investment cost but cause environmental pollution, harm to human, reduce useful insects in the garden. Mineral oil originated from organic is also considered as biological medicines which gave effective results to prevent pests on segment fruits. Dong Nai Bureau of Plant Conservation also warns farmers of applying to kill pests, red spider, pseudococcus Risso damaged to fruit trees and industrial trees. Besides, Agrifos is also used to treat rotten roots, sap dropping on durian; Bemetent treats green grasshopper on vegetable; Tiktack treats yellow medium-sized edible snail on rice…

To properties of biological medicines, according to directions of agricultural development in the next time, it is very necessary to apply positively biotechnology for plant conservation in the whole country in general and Dong Nai in separate. However, according to Bureau of Plant Conservation, biological pesticides are difficult to preserve, and quality is not stable according to processing method, other pesticides has slow and undiversified effects, and rely on temperature and moisture in environment, Therefore, encouraging farmers in biological products to conserve plant has to go along with opening short-term training classes for instructors.
