Cool, wet soils and improper drainage can lead to slow germination and establishment of soybean seeds making them more susceptible to attack by soil-borne seed and seedling pathogens. Using soybean seed treatment products can help reduce disease infections, which can result in more uniform plant stands, improved yield potential, and fewer replant situations.
An early planting date can increase soybean yield potential and is often recommended for high-yield soybean production. Reduced tillage and narrow row spacing are also key practices for obtaining maximum yield potential. However, soybean yield potential can be compromised by environmental stresses and a complex of soil-borne pathogens early in the season, which negatively affect root health and seedling vigor.
Germination and emergence are rapid at temperatures above 77 °F, but seeds can germinate at lower temperatures. Cool (less than 60 °F) and moist soil conditions can slow germination and establishment of soybean seeds, making them more susceptible to soil-borne seed and seedling pathogens such as pythium, phytophthora, and fusarium. Warm, moist soil environments favor the pathogen rhizoctonia.
Effects of unfavorable early-season planting conditions can be minimized by using products from Acceleron Seed Applied Solutions. Acceleron Seed Applied Solutions products for soybean contain multiple modes of action to provide broad spectrum control of diseases and insects and promote improved plant health through more rapid and increased emergence of seedlings under suboptimal soil conditions. Acceleron Seed Applied Solutions products for soybean can protect seeds and seedlings from certain diseases and insects for up to 30 days after planting. Three tiers of seed treatment products are available.
Acceleron® Seed Applied Solutions BASIC for soybean seed contains an exclusive fungicide combination featuring fluxapyroxad, pyraclostrobin, and metalaxyl, which provide excellent control of rhizoctonia, pythium, fusarium, and early-season phytophthora. Fluxapyroxad adds an additional fungicide mode of action for more complete, consistent protection from rhizoctonia and fusarium.
Acceleron® Seed Applied Solutions STANDARD for soybean seed contains the fungicide combination plus the insecticide imidacloprid for protection from early-season diseases plus protection from early-season soybean aphids and bean leaf beetle.
Acceleron® Seed Applied Solutions ELITE for soybean seed contains the fungicide combination plus Poncho®/ VOTiVO®. This product offers protection from the early-season diseases and insects mentioned above plus additional insect protection and protection against soybean cyst nematode (SCN) and other nematodes.
Acceleron® Seed Applied Solutions products for soybeans can be paired with ILeVO® to help provide additional protection from sudden death syndrome (SDS) and includes a biological mode of action for SCN, root-knot, and reniform nematodes. ILeVO can be used with SCN-resistant and other soybean products to manage nematodes in newly infested fields or fields with established infestations. ILeVO is the only seed treatment that provides early-season SDS control (both the root rot and foliar phases) and a true nematicide that kills nematodes in the seed zone.
Acceleron® E-007 SAT is a dry seed finisher that allows for faster drying of treated seeds and reduces the stickiness of treated seeds, thereby improving seed flow through seed handling and planting equipment.
Acceleron® B-200 SAT is a biological product for soybeans that contains plant-derived flavonoids. Flavonoids attract and stimulate the growth of beneficial microbes in the soil, which promotes their colonization on soybean roots, nodule formation, and nitrogen fixation. This results in enhanced nutrient availability and uptake, which can lead to a healthier crop and increased yield potential.
