ARE NE­MA­TODES ROB­BING YOUR FIELDS OF YIELD?

NE­MA­TODES ARE SILENT KILLERS

in a farmer’s field, caus­ing dam­age that can’t al­ways be seen and rob­bing yield along the way. When try­ing to com­bat these dif­fi­cult pests, farm­ers need so­lu­tions that of­fer im­pact­ful re­sults.

“Dam­age to plants oc­cur when ne­ma­todes feed on roots, which can heav­ily im­pact plant growth. Un­for­tu­nately, this

doesn’t al­ways de­velop above-ground symp­toms,” says Jim Schwartz, di­rec­tor of PFR and Agron­omy for Beck’s Hy­brids. “Even if above ground symp­toms do oc­cur be­cause of sig­nif­i­cant in­fes­ta­tion, they are of­ten spo­radic and im­i­tate other pro­duc­tion re­lated is­sues, like drought stress or fer­til­ity de­fi­ciency. Con­trol­ling ne­ma­tode pop­u­la­tions early can greatly di­min­ish the po­ten­tial for yield loss.”

Preva­lent in both corn and soy­beans, there are many types of ne­ma­tode species. Ecto par­a­site species ex­ist in the soil and may move around and “graze” on roots. Endo par­a­site species spend most of their lives feed­ing in­side the roots. Dif­fer­ent species are more pop­u­lar in dif­fer­ent soil types, for in­stance, ec­topar­a­sitic species are more com­mon in sandier soils. No mat­ter the species, all ne­ma­todes can lead to mois­ture and nu­tri­ent up­take re­stric­tions and lead to yield-rob­bing dis­eases, like root rot.

Each year, ne­ma­todes are re­spon­si­ble for more than $3 bil­lion loss due to crop dam­age*. While many ne­ma­tode species feed on both corn and soy­beans, soy­bean spe­cific species do not typ­i­cally feed on other plant types. Soy­bean cyst ne­ma­tode (SCN) in­fes­ta­tions can cut yields as much as 30 per­cent and not only cause stunt­ing, yel­low­ing, early death, re­duced nodu­la­tion and lower yields, but can also serve as an en­try point for other dis­eases. SCN is the num­ber one cause of yield loss in soy­beans and is preva­lent in ma­jor­ity of the soy­bean acres in the United States.

Schwartz says the most crit­i­cal time to con­trol ne­ma­todes is in the first 3045 days the seed goes in the ground. Ne­ma­sect™ con­trols ne­ma­todes within 24 to 48 hours and im­pacts both egg and ju­ve­nile ne­ma­tode pop­u­la­tions for up to 60 days. But this rev­o­lu­tion­ary ne­mati­cide doesn’t stop there. With its mul­ti­ple modes of ac­tion, it also acts as a pow­er­ful in­sec­ti­cide and has ac­tiv­ity on many soild welling in­sects.

“Dam­age to plants oc­cur when ne­ma­todes feed on roots, which can heav­ily im­pact plant growth. Un­for­tu­nately, this doesn’t al­ways de­velop above­ground symp­toms.”

Man­age­ment prac­tices like crop ro­ta­tion, elim­i­nat­ing win­ter an­nual weed species, plant­ing re­sis­tant va­ri­eties, plant­ing early, min­i­miz­ing growth stresses, and us­ing seed treat­ments can all aid farm­ers in the fight against ne­ma­todes. Farm­ers should take ad­van­tage of the tools at their dis­posal to con­trol dam­ag­ing ne­ma­todes and pro­tect yields, es­pe­cially when one of­fers the ef­fec­tive­ness of Ne­ma­sect.

A rev­o­lu­tion­ary ne­mati­cide and in­sec­ti­cide, Ne­ma­sect comes stan­dard as part of Beck’s Es­ca­late¨ seed treat­ment on corn and soy­beans. The best part? It comes at no ad­di­tional charge, so it’s putting even more money back into farm­ers’ pock­ets. Farm­ers can be con­fi­dent their crops have an added de­fense against ne­ma­todes and in­sects, and can look for­ward to ad­di­tional yield pro­tec­tion. *So­ci­ety of Ne­ma­tol­o­gists. “In­for­ma­tion on Ne­ma­tol­ogy.” 2018.
