For optimum yield potential, soybeans must be protected from insects, diseases, and nematodes. Slow germination and stand establishment of soybean seeds in cool, wet soils can make them more susceptible to attacks by insects, nematodes, and soil borne seed and seedling pathogens. Controlling these pest and pathogens and increasing nutrient uptake can improve germination and emergence, enhance plant vigor, and increase yield potential. Soybean seed applied products can reduce disease infections and protect seed from insects resulting in more uniform plant stands, better yield potential, less incidence of replant. Soybean seed protection is always important but where continuous soybeans are being contemplated, seed protection is even more important.
Disease: 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. These pathogens can invade plant roots causing tissue decay, pre-emergence damping off, and early post-emergence seedling death. Pythium species may cause decay before germination and seeds become soft and rotten. Infected seedlings may die prior to emerging from the soil or shortly thereafter. Phytophthora sojae also causes a wet, soft rot of the seed or seedling tissue, similar to that of Pythium. Symptoms of Rhizoctonia solani infection appear on seedlings as dry, dark reddish-brown lesions just above the soil surface.
Insects: Early-season insects such as soybean aphids and seed corn maggots, as well as later-arriving bean leaf beetles, can reduce yield potential. From emergence throughout the growing season, plant parasitic nematodes can penetrate and feed on soybean roots, reducing the plant's ability to utilize water and nutrients and may create an entry point for other pathogens.
Effects of unfavorable early-season planting conditions can be minimized by using Acceleron® Seed Applied Solutions.
Acceleron Seed Applied Solutions products for soybean feature multiple modes of action that provide broad spectrum control of diseases and insects and promote improved plant health through more rapid and increased emergence of seedlings under certain cold soil conditions.
Acceleron Seed Applied Solutions products for soybean can protect soybean seeds and seedlings from certain diseases and insects for up to 30 days after planting. Protecting soybean against attack by soybean aphids and bean leaf beetles is a good tactic to prevent the viral diseases soybean mosaic virus and bean pod mottle virus that can be transmitted by pests.
Additional Products: 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.
