The news this week was the China approval of Enlist E3 soybeans (soybeans tolerant to glufosinate, glyphosate and 2,4-D) for import. China also approved the import of Syngenta’s MGI soybeans. Those soybeans are tolerant to Callisto, glufosinate and Balance herbicides. My understanding is this MGI trait in soybeans still needs EU approval so unlike the Enlist E3 soybeans they will not be offered for sale this year. Continue reading
Most farmers had their fair share of seed quality issues during fall 2018, including many seed bean producers. The commercial seed supply is expected to be impacted some by weathering at harvest, with severity depending on maturity group and field location. Continue reading
The fungus Macrophomina phaseolina is a soil-borne pathogen that infects nearly 500 species of plants including soybean, cotton, and corn and causes the disease charcoal rot. What does this mean for West Tennessee farmers? Continue reading
Once you’ve sample your field, had it tested, and you have soybean cyst nematode (SCN), you’ll want to consider SCN-resistant varieties, but there are certain populations of SCN that can reproduce on certain SCN-resistant varieties so how do you know what resistant variety is best for your field – you find out the HG Type of your population – a costly test that UT is offering for free this year to TN farmers. Continue reading
The most recent inquires have been on what is the likely yield loss from dicamba drift to non-Xtend soybeans? These have come from fields that showed dicamba drift injury to the soybeans this summer and now are staying green delaying harvest this fall.
These questions have been frequent the last few years. Research funded by the United Soybean Board was conducted in the Mid-south and Midwest this summer to help answer the question. Continue reading
With the extended wet weather in late September, growers in many parts of the southeast are dealing with varying degrees of seed quality issues in soybean as they move through harvest. Continue reading
The last two weeks we’ve published articles highlighting the free soil testing for 2018, which is screening for the ‘silent yield robbers’: pathogenic nematodes and charcoal rot. This article gives a brief description on how pathogenic nematodes differ – their effect on yield and different management options. Continue reading
