Sudden Death Syndrome (SDS) has started showing up in soybean fields in Tennessee. The cool, wet season Tennessee has experienced, similar to last season, has been conducive for the disease to develop in susceptible varieties. Continue reading
There have been several reports of fall armyworms in wheat beans. Fields with weedy grasses or volunteer wheat are especially prone to infestations. The larvae start out on grasses and move to soybean (usually after a herbicide application takes the grass out). However, fall armyworms can sometimes make an appearance even if the fields are not grassy. Continue reading

COTTON IN NEED OF HEAT UNITS
The past week was very favorable for field work. Rains varied greatly across the State, providing some crops with needed moisture while leaving others stressed. With temperatures remaining cooler than normal, however, cotton growers are still concerned that the crop will not receive adequate heat units. A good general rain is still needed in some parts of the State. Continue reading at Crop Progress 7 27 14.
By request, I am providing a list of active ingredients and trade names (see below). This does not include all examples. Feel free to make comments about other “generic” trade names you may be using. Please keep in mind that formulations may vary considerably, and thus, rates may need to be adjusted accordingly. Also, not all products be labeled for the same crops. It is your responsibility to follow instructions on the insecticide label. The information below is also available in UT’s insect control recommendations for field crops. Continue reading

RAINS HINDRENCE FOR SOME, WELCOMED BY OTHERS
With no end in sight for some producers, rains have drowned out some crop acreages and prevented planting of others. The wet weather is, however, helping soybean and corn development but heat units are still needed for the cotton crop because of its sensitivity to adverse environmental conditions. Continue reading at Crop Progress 7 20 14 .
As we get further into the year, bugs begin to enter our fields, disease onset starts to occur, and weeds continue to flourish, our chances of making tank-mixed applications increase. This ultimately makes spray nozzle selection more challenging as most products require different droplet sizes. Continue reading
These are a couple of new pests we need to be on the lookout for. Let’s start with the good news. Continue reading
This article really pertains to insect management to all crops, but I’ll highlight a couple of relevant scenarios. A lot of the comments relate to a common theme. Insect management is often reactive. Spraying too early decreases effectiveness, often increase overall control costs, and unnecessarily select for resistance. Many of our most commonly used insecticides offer Continue reading
