New biotechnological development improves rice crops
The Universidad Nacional de Colombia (UNal) began the technological transference of Actybac, a biotechnological product which comes from Streptomyces racemochromogenes bacteria, which control bacteria responsible for rice blast, the main rice disease.Bogotá D. C., 02 de agosto de 2016 — Agencia de Noticias UN-
Annual Colombian rice production can reach up to 2.7 million tons from more than 500,000 planted hectares.
The UNal Biotechnology Research Institute has already produced 4 other products to help nurture rice crops.
Currently they are fine-tuning the new development and they think that for the beginning of 2017 they will begin to market the product among rice growers.
The product is new to a list of 4 biotechnological tools with the UNal seal to improve rice, which has an annual production in Colombia that surpasses 2.7 million tons.
The other 4 products developed since 2002 are 2 plant growth promoters using Azospirillum and Azotobacter bacteria, which promote nitrogen fixation; and Fosfobiol and Trifesol, fungicides processed using 2 types of fungus which help in plant tissue formation.
Streptomyces racemochromogenes is the active bacteria in Actybac and has the capability to control 4 forms of pathogenic bacteria responsible for not allowing nutrients to reach the spike and hence not forming grain.
Essentially in their growth process with carbon and nitrogen, benign bacteria produce metabolites which inhibit molecule action which produce growth and propagation of pathogens.
The established dosage of the product to shield grain crops is one liter per planted hectare.
The work of the scientists to produce each one of these natural fertilizers is looking for beneficial soil microorganisms and isolate, identify and quantify their action capability and finally multiply them in reactors to reapply them to the soil for the benefit of plants.
“Microorganisms are naturally in the soil, the problem is that soil has suffered so much abuse that these beneficial populations have been disappearing or decreasing,” said Chemical Engineer and member of the UNal Bioprocesses and Bioprospection Research Group Professor Nubia Moreno.
Although this is not an exclusive factor, as variables such as weather, soil, seed, irrigation and technification impact production, with these 5 biological products yield is increased, on average, up to 10%.
Additionally, the quality of the products has improved, as agrochemical use is reduced, improving food safety.(Por: Fin/HEVC/MLA/APBL
