Aimed to develop a new biopesticide to control the pepper root rot and root-knot nematode disease complex in Vietnam, the study focused on the identification of the new biopesticide component, the development of production technology and the evaluation of its effect on the reduction of pathogens in the pepper growing soil. The results showed, that...

Root disease caused by various soil-borne pathogens affect the production of black pepper (Piper nigrum L.) in Vietnam. The present study aimed at evaluating the efficacy of a consortium of a nematode-trapping fungus (Arthrobotrys oligospora) and antagonistic microorganisms (Bacillus velezensis, Streptomyces enissocaesilis, and Trichoderma asperell...

This biofertilizer manual is the product of the Biofertilizer Project in FNCA (Forum of Nuclear Cooperation in Asia). Eight countries, China, Indonesia, Japan, Korea, Malaysia, Philippines, Thailand, and Viet Nam participate in this project. The Editor-in-Chief is Dr. Pham Van Toan, the Project Leader of Viet Nam. The activities of this project are...

Background Fusarium root rot disease in Indian mulberry (Morinda officinalis How.) (FRRBK), caused by Fusarium proliferatum (FP), is widespread and responsible for serious economic losses in Viet Nam. The efficacy of a new bio-product named MICROTECH-1(NL) is compared with other commercial products for suppression of FP under in vitro, pot, nursery...

Aimed to apply the nematophagous fungi in controlling plant parasitic nematodes on coffee and black pepper in Vietnam, nematode-trapping fungi strains were isolated, selected, tested in laboratory, greenhouse and field. Three of 153 isolated nematophagous fungi strains from soil samples collected from Dak Lak and Gia Lai provinces were selected, la...

Biofertilizers are products containing living microorganisms having the ability to convert nutritionally important elements from unavailable to available form and enhance the plant growth through biological processes. The book chapter summarized the research, development, application, and regulatory requirements of biofertilizer in Vietnam and cont...

With the aim to apply the beneficial microorganisms to peanut (groundnut (Arachis hypogaea)) growing in sandy soil of Binhdinh province in Vietnam, the paper was conducted to study the isolation, selection of N-fixing, phosphate, potassium solubilizing and slime producing microorganism from sandy soil and peanut root samples, and evaluate the capab...

Biofertilizer research for rice in Vietnam has focused on the isolation and selection of strains that can fix nitrogen, solubilize inorganic phosphates, stimulate plant growth, and breakdown soil organic matter. This paper assesses the consistent positive effect of BioGro on grain yield and agronomic parameters, including the rates and times for it...

Sarcocystis singaporensis is a parasitic protozoan native to southeast Asia, which cycles between the reticulated python and rodents of the genera Rattus and Bandicota to sustain its life. Since 2001, a formulation containing live parasites in various life stages is being commercialized for rodent control in various Southeast Asian countries after...

This chapter concentrates on the potential effects of transgenic cotton on the soil ecosystem of three major cotton growing areas in Vietnam: the coastal lowlands region, the central highlands (eastern and western Truong Son Mountain Range) and the south-eastern region. Soils in these three regions are very different, so it will be necessary to ass...

This book (13 chapters), the fourth in a series (the first, second and third books focused on Bt maize in Kenya, Bt cotton in Brazil, and risk assessment and management of transgenic fish, respectively) that provides scientifically peer-reviewed tools that can help developing countries strengthen their own scientific and technical capacity in biosa...

This chapter discusses the following procedures for risk assessment in Bt cotton using the non-target risk assessment model developed by scientists of the GMO ERA Project ("International Project on GMO Environmental Risk Assessment Methodologies", which is a continuation of the GMO Guidelines Project, which was launched by scientists of the Interna...

There are widespread attempts by scientists and commercial producers to improve yields of crop plants with plant growth-promoting rhizobacteria (PGPR). Importantly, there is now statistically significant evidence (e.g., Nguyen et al., 2003) that benefits from inoculation can be obtained under field conditions, so reducing the need for high inputs o...

Many international forums have identified the need for comprehensive, scientific methods for the pre-release testing and post-release monitoring of transgenic plants to ensure their environmental safety and sustainable use. In response to this requirement, the International Project on GMO Environmental Risk Assessment Methodologies develops biosafe...
