A newly published study led by researchers from the University of Georgia and several partner institutions reveals a discovery that could lead to new control strategies for a tiny-but-persistent agricultural pest that causes enormous soybean losses. Microscopic soybean cyst nematodes...

Field performance of 40 varieties in a southern RKN-infested field, 2020

• By Michael Emerson, Travis Faske and Jesse Kelly • The southern root-knot nematode (Meloidogyne incognita) is the most important yield-limiting plant-pathogenic nematode that affects soybean production in the mid-South. It is found in nearly all soybean-producing counties in Arkansas...

New soybean variety has SCN resistance conferred from 1930’s discovery

A new soybean variety – with resistance to soybean cyst nematode derived from the breeding line PI 89772 – is being released by Syngenta in small quantities in 2020. Syngenta is sharing seed with university researchers and farm cooperators...

Test in spring for SCN, soybean’s silent killer

Test for soybean cyst nematode in the spring before planting, says University of Missouri Extension plant pathologist Kaitlyn Bissonnette. Data from MU researchers shows SCN field populations are becoming more virulent on commercial soybean cultivars, she says. SCN quickly began spreading...
