Nematodes get the (bio) boot in Brazil
Meloidogyne incognita and Pratylenchus brachyurus won’t be names that roll off the tongue for most of us. At least, not in their Latin form.
But switch into common language and it’s a fair bet that the root-knot nematode and root-lesion nematode will prompt some familiarity. They have the dubious distinction of being the two most damaging nematodes – tiny worms – anywhere in the world.
M. incognita is far and away the most significant, capable of adapting to (i.e. damaging) more than 3,000 different plant species. P. brachyurus is also widely spread amongst different crops, from maize to citrus to coffee, not forgetting soybeans, sugar cane, cotton and yam.
They’re a problem, causing billions of dollars of losses and costs for farmers around the world. And there’s no simple treatment: the nematodes’ ability to colonise so many crops presents difficulty in adopting universal management strategies to deal with them, whether chemical controls such as sprays, fumigation, or seed treatments, or cultural controls in the form of tillage, crop rotation or cover crops.
So is there a third way worthy of investigation? Never one to shirk a challenge, FertiGlobal Brasil started a search for innovative solutions that might help growers reduce the nematodes’ effects on crop yields and quality. Brazil – a true powerhouse in global agriculture – grows in some quantities the crops in which these pests cause so much damage:
- One in three cups of the world’s coffee comes from Brazil
- Seven out of every ten glasses of orange juice originate in Brazil
- Brazil’s the biggest exporter of sugar cane and soybeans
Biological trials
Why use chemicals if (a) they’re not totally effective and (b) if you don’t have to? That’s the Fertiglobal approach to crop production; it’s the approach enthusiastically taken by the Brazilian team in their research.
What you’re about to read is the first we’ve talked in any detail about our new bionematicide. We’re very excited about it and not just because of the results we’ve seen in the very first trials conducted last year.
It’s also that Brazil just happens to be one of the best countries, the best markets, in which to bring new bio-based products to market. Its structured but productive regulatory framework allows farmers to benefit from biological products in the field, thanks to a quick and smooth process that sees the implementation of new policy and swift registrations of new products. There really is no better place to roll out innovations like this, given the volume of crops, the two-crop growing season, and farmers’ willing adoption of new products and techniques.
Catchy names
It’s still a bit too early to give too much away about our exciting new product, so for now let’s just refer to it by prototype 1 and prototype 2, the result of long studies in the lab to identify biological control agents that are capable of delivering an agronomically valuable result against root nematodes.
- In the field trials, we evaluated the bionematicide against the two nematodes, using a common bean crop with natural mixed infestation.
- Applications of the nematicide were made in-furrow or as seed treatment
- An existing bionematicide (containing Bacillus subtilis and Bacillus licheniformis) was used as a microbiological standard
- Nematode populations were assessed at 25 and 50 days after emergence (DAE)
- Yield was measured at harvest (14% moisture)
Results

Our team’s comments
‘What a result!’ was the overwhelming reaction.
For the first field trial to show such promising results was a terrific vindication of the team’s hard work and diligence in developing the product. Add to that their deep and detailed understanding of the active’s behaviour, guiding its deployment in trials and contributing to the success seen in the charts above.
While they speak for themselves, it’s helpful to pick up on a few points:
- Clearly the in-furrow application at the 0.6l/ha rate delivered the best overall biological performance, as well as the highest grain yield.
- Seed treatment performed well against M. incognita in roots but was not robust for P. brachyurus management when used alone.
- Commercially, what’s of most interest is the combined reduction of root infection, egg density and reproduction. It’s this combination – effectiveness in the current crop, and a reduced incidence in the next crop – that present the best agronomic return.
Next steps?
Well, results like these are exciting. Not just for the team in Brazil, but for everyone who supports the FertiGlobal ideal: being active in crop protection without needing to be active in ‘crop protection chemicals’.
It’s been one thing to demonstrate how a healthy crop – achieved through appropriate nutrition – can be a crop that’s capable of defending itself against pests and disease threats. But it’s quite another to move beyond that, and to show that in the cases where healthiness just isn’t enough – such as with nematode attack – we can still deliver the biological solution that works.
Keep watching this space. There are still a few more hoops to jump through before we can tell you that prototype 1 and prototype 2 are ready for Brazilian farmers, but it won’t be far off.
Of course, they’ll come with a better name too.
