This
is difficult to to read unless you have a background in writing
scientific journal articles. The reason I included this summary is for
those of you who do have this background and it interests you and I
summarized it for the layperson. Highlighting is mine.
For me, this suggested the possibility of using composted poultry manure to help reduce populations of root knot nematode. By the way, Carbofuran is the chemical name for a highly toxic pesticide. I worked with this insecticide while a student at the University in some trials back in the 1970s with the entomology department at Colorado State University. The product I worked with was called by the manufacturer Furadan.

Another take-home lesson from this research article is that when this insecticide/nematicide (pesticide) was applied to watermelons the plant was not able to transport this product to the melon itself in any measurable amounts using highly sophisticated gas chromatography- mass spectometry.

From reading this abstract or short summary below of the article we don't know the levels at which the insecticide was measured (ppb, ppt, etc). We also don't know if any related compounds were detected or even measured.
The good news? Composted chicken manure may be a good substitute for pesticides when trying to control nematodes in the gardens, fruit trees or landscapes.

Nematicidal Effects of Carbofuran and GC-MS Analysis of its Residue in Pineapple Fruits
Concerns over the safety of food items from fields treated with
nematicides had risen in recent times. In this study, two field
experiments arranged in a Randomized Complete Block Design were
conducted to assess the efficacy of poultry manure and carbofuran in
suppressing nematode population and determine the residual presence of
the nematicide in pineapple fruits. Three poultry manure rates (0, 20
and 25 metric tonnes per hectare) and carbofuran treatments (0, 3.0 kg
a.i/ha and 3.4 kg a.i/ha) were applied to two naturally infested
pineapple fields. Twenty core soil samples per plot were collected from
plants rhizosphere at 3, 6, 9, 12, 15 and 18 months after planting.
Fifty grams each of chopped pineapple samples from the
carbofuran-treated and untreated plots was extracted with 20ml of ethyl
acetate solution for fruit analysis to determine the residual presence
of carbofuran using Gas Chromatography-Mass Spectrometry (GC-MS). The
study indicated that poultry manure and carbofuran significantly (P≤
0.05) suppressed nematode population in both locations and promoted crop
yield. The GC-MS test showed that carbofuran and its metabolites were
not detected in the pineapple fruits, suggesting that carbofuran is not
likely to constitute dietary risks to consumers of fruits from treated
plots.
