Goncalves da Silva, Maysa Siqueira published the artcileVolatile fatty acids from whey volatilome as potential soil fumigants to control Meloidogyne incognita, Application In Synthesis of 123-29-5, the main research area is whey volatilome potential soil fumigant control Meloidogyne incognita.
Organic residues emit volatile organic compounds (VOCs) that are toxic to plant-parasitic nematodes (PPNs). In this study, we demonstrated that whey produced by cow milk emit VOCs that are toxic to Meloidogyne incognita second-stage juveniles (J2), causing immobility above 80% and significant (P < 0.05) mortality compared to controls. The anal. of the volatilome done by gas chromatog. coupled with mass spectrometry revealed 28 compounds, predominantly carboxylic acids and esters. Four of those volatile fatty acids (VFAs), namely acetic acid, octanoic acid, Et octanoate, and isovaleric acid, were chosen to further studies. The four tested VFAs were toxic to M. incognita J2, with lethal concentration values required to kill 50% of the nematode population (LC50), ranging from 134.30 to 236.08μg mL-1. However, on eggs, only acetic acid and Et octanoate were consistent with J2 hatch inhibition, reaching 80% at a concentration of 1000μg mL-1. In a greenhouse assay, when the VFAs were applied as soil fumigant, M. incognita infectivity and reproduction were significantly (P < 0.05) reduced compared to the neg. control (water). Among them, Et octanoate application reduced (P < 0.05) the number of eggs to the level of the com. fumigant dazomet. Overall, the volatile compounds released by whey were toxic to M. incognita J2 and contained a great diversity of mols. Among the VFAs, Et octanoate stood out and showed the potential to be used in future field studies. Crop Protection published new progress about Carboxylic acids Role: AGR (Agricultural Use), BIOL (Biological Study), USES (Uses). 123-29-5 belongs to class esters-buliding-blocks, name is Ethyl nonanoate, and the molecular formula is C11H22O2, Application In Synthesis of 123-29-5.
