Yield Loss in Soybean Caused by Heterodera glycines.
Yields of four soybean cultivars were measured for 4 years in a field infested with Heterodera glycines race 3 and in a field infested with H. glycines race 14. Cultivars included Hutcheson (susceptible to both races), Deltapine 415 (resistant to race 3 and susceptible to race 14), Asgrow 5979 (resistant to both races), and Harwig (resistant to both races as well as most other known races of H....

Effect of Soybean Cyst Nematode (Heterodera glycines) on Yield of Resistant and Susceptible Soybean Cultivars Grown in Ohio.
Soybean (Glycine max) producers in Ohio rarely use soybean cyst nematode (Heterodera glycines, SCN)-resistant cultivars because of concerns over limited yield potential and lack of resistance to Phytophthora sojae. A two-year study was initiated to determine grain yield and nematode population increase on soybean cyst nematode-resistant cultivars in maturity groups II and III in production fiel...
متن کاملInfluence of Planting Date on Damage to Soybean Caused by Heterodera glycines.
Bragg soybeans were planted in nematicide-treated and nontreated plots on 15 May, 15 June, 1 July, and 15 July in 1980 and 1981 to determine the influence of planting date on damage caused by H. glycines. Although earlier studies showed the nematode was sensitive to high soil temperatures (> 34 C), late planting did not reduce damage caused by the nematode. Yields from plots treated with 1, 2-d...
متن کاملDistribution of Heterodera glycines in Ohio.
A 4-year systematic survey for the presence of soybean cyst nematode Heterodera glycines in Ohio soybean fields was initiated in 1992. A total of 667 soybean fields in 63 counties was sampled. Heterodera glycines was present in 91 fields in 40 counties based on soil samples collected, and in one field in each of three additional counties based on soil samples submitted to the Plant and Pest Dia...
