Effect of pyraclostrobin and thiaphenate methyl on seed germination, plant growth and disease control of soybean (Glycine max L. Merrill)

The seedling death due to Scerotinia and incidence of Anthracnose is causing loss in soybean seed germination and later on seed production. Seed treatment with pyraclostrobin (0.1g a.i.), thiophenate methyl (0.9g a.i.) and carbendazime (3 g/kg seed) were tried to study the effect on seed germination, seedling mortality, plant growth and seed yield. The intensity of Anthracnose disease on plant during R3 stage was studied. The seed treatment with pyraclostrobin, thiophanate methyl and carbendazine had increased seed germination by 13 to 25% over control and at later stage seedling death was significantly reduced to 0.61% from 9.8% in control. There was significant increase in plant growth (plant height) and up to 29.6% increase in yield was observed. The incidence of anthracnose was significantly controlled by pyraclostrobin and thiophanate methyl. The seed treatment with pyraclostrobin and thiophanate methyl was proved very effective to improve in seed production controlling Scerotinia and anthracnose.
