After years of research, Tay Nguyen University has found a way to use bio-products in pepper cultivation.

Accordingly, the school has built up reasonable production models to ensure sustainable cultivation, bringing high economic efficiency, friendly with the environment, bringing new awareness to people in the cultivation of trees. pepper.

The scientists used chitin, chitosan and chitosan oligomer preparations for pepper during the basic construction period.

Bioproducts are extracted from crab shell, insect, fungal cell wall. These are non-toxic, biodegradable and environmentally safe components.

The chitosan and chitosan oligomer components are active in plant growth promoters, increasing the number of beneficial microorganisms, limiting soil damage and enhancing the plant's resistance system to plants.

Apply to production, the compositions are irrigated for pepper three times, each 15 days apart. After three months, the amount of mold and microbes in the soil increased rapidly.

Most of these pathogens and molds are capable of synthesizing enzymes that dissolve cell walls of pathogenic fungi and some insects, which help pepper plants to increase resistance to fungi. Disease in the soil.

During cultivation, application of chitosan and chitosan oligomer resulted in a significant reduction in the number of Fusarium fungi for pepper plants.

In addition to the indirect increase in the number of molds and microbes, chitosan and chitosan oligomer have a direct Fusarium antifungal activity. Fusarium fungus is completely inhibited by culture on chitosan and chitosan oligomer concentrations of 0.1-0.15%.

The above-mentioned biological products also reduce the number of nematodes in pepper roots to eight times the number of non-inoculated orchards.

On the other hand, when spraying the 200mg / l chitosan oligomer on leaves, the chlorophyll content in the pepper leaves increased by nearly 50%. The tree is stimulated to grow the main trunk and branches grow faster.

Actual production has shown that chitin, chitosan and chitosan oligomer preparations when irrigating or fertilizing the soil have been shown to be effective in improving microbial populations in pepper cultivation, contributing to the reduction of Significant number of fungal pathogens on pepper plants.

To absorb the research and experimental results of Tay Nguyen University, the Department of Agriculture and Rural Development of Dak Nong is applying the use of biological products in pepper cultivation in the period of basic construction of Many farmers and farmers have achieved good results. In which, popularly applied in many pepper growing provinces such as Dak R'lâp, Cu Jut and Gia Nghia.

Pepper is a high economic value industrial plant but nowadays, the cultivation of this kind of tree is very difficult. The main cause is widespread devastation of rapid yellowing of dead leaves caused by viruses.

Currently, chemical control measures are ineffective and polluting the environment. The use of probiotics in pepper cultivation has been successful initially, bringing great potential for sustainable production development. In the time to come, scientists will continue to study the biological preparation of pepper cultivation in the business period, to improve production efficiency for farmers.
