Timing of fertilizer application can impact the release of nitrous oxide

Demands for more sustainable agriculture have meant that biological alternatives are increasingly required to control pests and diseases in crops. This is the case of phytonematodes.
It is estimated that between 8,8 and 14,6% of all agricultural production in the world is lost to nematodes. This causes losses of around US$157 billion per year (Sasser & Freckman, 1987; Koenning et al., 1999; Abad et al., 2008; Nicol et al., 2011). Currently, more than 100 species of these animals are known. There are more than 50 genera associated only with soybean cultivation.
In Brazil the situation is no different. Data from the Brazilian Society of Nematology (SBN) indicate that losses are estimated at R$35 billion per year, of which R$16 billion in soybeans alone.
Experts in the field claim that there are more than 200 natural enemies of these parasites, including fungi and bacteria, from which biological nematicides are extracted, which can be one of the strategies used in the integrated management of the pest.
Seeing the need to bring innovative, effective and economically viable tools to assist rural producers' daily lives, Simbiose developed technology that uses bacteria Bacillus amyloliquefaciens – discovered in the Brazilian Cerrado – as the product’s active ingredient.
“NemaControl was developed based on the search for a microorganism that was capable of associating with the plant and combating nematodes through different mechanisms”, says Marcelo de Godoy Oliveira, CEO of Simbiose.
"The Bacillus amyloliquefaciens it colonizes the plant's root system from the moment it is inoculated into the seed or applied via the planting furrow and, thus, feeds on the root exudates”, he explains.
Nematode control occurs when Bacillus amyloliquefaciens it starts to produce and release toxins and antibiotics into the soil, protecting the plant's root system.

This is an agreement signed between the State Government, municipalities, associations and companies in the grain chain and the Federal Public Ministry with the aim of ensuring the commitment of the productive sector not to sell products originating from illegally deforested areas.
