Meeting season is in full swing, and there are several educational opportunities fast approaching (see below). Pesticide re-certification points and CCA points will be available at all these meeting. Additional details will be provided soon! Continue reading
The 2016 Weed Control Manual for Tennessee (PB1580) and the 2016 Insect Control Recommendations for Field Crops (PB1768) are now available online. As always, hard copies will be made available at various county and state production meetings and at Extension county offices. But they are always a couple of clicks away at UTcrops.com.
Planting wheat after sorghum can be done successfully. Wheat stands are most uniform when the sorghum crop is killed with glyphosate and at least a month or more has passed between sorghum harvest and wheat planting. Continue reading
Although stink bug populations remain generally light, there are now some reports of populations exceeding the treatment threshold of 9 per 25 sweeps. Remember you should probably double this threshold once a field reaches R6. Calls are also trickling in about defoliation Continue reading
The questions of the week have been … when/if should I put an insecticide out with my harvest aid for sugarcane aphids in sorghum, or if you are still a week or more from making a harvest aid application, should you hold off with the insecticide until making this application. First, I’ll refer you to a good article from Mississippi State University from last week. This article also addresses if, when, and what harvest aids can be applied. Continue reading
Although a common comment this week has been that sugarcane aphid (SCA) infestations are not spreading rapidly, with most infestations concentrated on field edges, we are steadily treating more and more sorghum fields. You can assume SCA are present in essentially all fields in West Tennessee, but fields requiring treatment are scattered across the area (see below). It hasn’t always been true, but a common theme is that many of the fields treated within the last few weeks with a pyrethroid insecticide are those that have required treatment for aphids.

Early planted sorghum is maturing and producers will need to decide soon if they want to spray a harvest product to aid in combining. A harvest aid kills the grain sorghum plant (glyphosate) or dries up leaves (sodium chlorate) and allows easier cutting where stands are thick, removes food source from heavy sugarcane aphid infestations, or is a way to clean up grasses or vines. Aim herbicide is labeled to desiccate vines in sorghum but is not an effective crop desiccant. Continue reading
