CONTROL RESISTANT APHID POPULATIONS AND PROTECT SOYBEAN YIELD POTENTIAL The well-documented development of resistant insect pest populations dates back to the early 1900s. Farmers in Iowa and Minnesota can attest to th e p ro p e n s it y fo r res is ta n ce d eve l o p m e nt a f te r a t te m p t i n g to c o n t ro l t h r e s h o l d - l eve l populations of soybean aphids between 2000 and 2008 with pyrethroids. 鈥淥ne season, heavy aphid populations were reported as far south as Missouri,鈥 said Dennis Holland, market development specialist with Corteva Agriscience. 鈥淭hat was really unheard of at the time, but cooler summer temperatures can accelerate aphid populations in any given year.鈥 Aphids can cause up to 50% yield loss, especially when infestations reach the commonly advocated threshold of 250 aphids per plant between early growth stages (pod fill) R1 to R5.1 鈥淪everal growers I鈥檝e spoken with who made applications with a single mode-of-action pyrethroid product scouted those 铿乪lds three to 铿乿e days later and still found aphid populations meeting threshold,鈥 Holland said. 鈥淭horough scouting is keytoverifytheeffectiveness of any insecticide application, even late into the plant鈥檚 reproductive growth stages.鈥 is more readily available and preferred. This is especially common during heavy infestations. North Dakota State University aphid research con铿乺ms a yield increase with Ridgeback insecticide.2 鈥淚t鈥檚 also tank-mix-friendly with fungicides, which could reduce trips across the 铿乪ld when treating for aphids and foliar diseases.鈥 Holland said. 鈥淒on鈥檛 forget the importance of good coverage. Even though 10 gallons per acre is recommended for a ground rig, I鈥檓 not opposed to using 15 to 20 gallons.鈥 Some weather forecasters expect the La Ni帽a weather pattern to weaken and shift toward El Ni帽o later this growing season, possibly bringing weather that swings between cooler and warmer temperatures. 鈥淚f this shift occurs, maintain a vigilant scouting regimen and be ready to call your local retailer to discuss all the benefits and added value Ridgeback insecticide offers through its unique mode of action,鈥 Holland concludes. GO WITH MULTIPLE MOA, FLEXIBILITY Aphid populations can sometimes increase after foliar applications because resistant aphids survive and reproduce. This exacerbates the cycle of resistance and increases the need for a more effective insecticide. 鈥淭his is where Ridgeback insecticide can be a great product solution 鈥 in regions where soybean farmers battle infestations of aphids,鈥 Holland said. 鈥淏ringing an additional mode of action, sulfoxa铿俹r (Group 4C) is 铿乪ld-tested and proven to control soybean aphids, as well as Japanese beetles, spider mites and other pests, while also strengthening resistance management stewardship.鈥 Ridgeback庐 insecticide with Isoclast庐 active works by contact and ingestion.
