Rye (Secale cereale L.) has been shown to be effective in minimizing the damage caused by root-knot nematodes (Meloidogyne incognita (Kofoid and White) Chitwood) when grown as a cover crop and then incorporated into the soil prior to planting. It has been suggested that the release of low molecular weight organic acids during the decomposition of rye is the cause of the nematicidal effects. This study was conducted to quantify the concentration and persistence of formic, acetic, propionic, butyric, and valeric acids in soil solution following the incorporation of fresh rye foliage. Formic and acetic acids were detected by means of ion exclusion chromatography, primarily in the first 24 h following addition of rye, and at concentrations <450 μmol/l. The effect of the rye treatment on the root-knot nematode population was determined by growing tomato plants (Lycopersicon esculentum Mill.) in the rye-amended soil and assessing the nematode damage to the root systems. Despite the low concentrations of organic acids detected, the rye treatment resulted in a significant suppression of root-knot nematode activity. To determine the fate of these acids in soil, an addition of each acid was made to a field soil resulting in a soil water concentration of 1500 μmol/l for each acid. Soil solution samples were collected every 2 h for 10 h and analyzed for the five added organic acids by means of ion exclusion chromatography. The concentration of all acids declined by 54–97% over the 10 h incubation. Although low molecular weight organic acids may be one of many factors that contribute to restriction in root-knot nematode damage, these acids do not appear to be solely responsible for the nematicidal effect of the rye.}, number={3}, journal={APPLIED SOIL ECOLOGY}, author={McBride, RG and Mikkelsen, RL and Barker, KR}, year={2000}, month={Nov}, pages={243–251} }

A greenhouse study was conducted to determine the duration of the effectiveness of rye decomposition in controlling root-knot nematode damage in relation to the time between rye incorporation and cotton planting. Fresh, chopped-rye foliage was mixed into pots of soil and root-knot nematode eggs were added to the rye + soil mixture or a non-amended soil at 0, 1, 3, 5, 7, 9, 11, 13, 15, 17, 19, and 21 days following rye incorporation. This resulted in a sequence of pots containing nematode eggs exposed to rye at different stages of decomposition. Cotton plants were transplanted into the pots after the addition of nematode eggs and assessed for damage after 28 days of exposure. Although the effectiveness of the rye treatment declined over the 21 days of the incubation, the root-knot nematode populations were significantly reduced by the rye treatment for all planting dates. This suggests that it is not necessary to plant cotton immediately after plowing in a rye cover crop, thereby providing some flexibility in the cotton planting date, minimizing any associated phytotoxicity to the young cotton plants.}, number={3}, journal={APPLIED SOIL ECOLOGY}, author={McBride, RG and Mikkelsen, RL and Barker, KR}, year={1999}, month={Dec}, pages={231–235} }
