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.

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

Crunch Time for Insect Management in Cotton
Author: Scott Stewart, IPM Extension Specialist No Comments

The next 2-3 weeks is traditionally the most critical window for managing insect pests in cotton. We are setting the bolls that will make or break our crop, and it is harder to recover from significant boll injury than it is to compensate for the loss of early season. This mid-flowering window is the time when immature plant bugs, stink bug, and bollworm infestations may all coincide. Moth traps are beginning to show the onset of our traditional bollworm flight. 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 .

Proper Nozzle Selection for Pesticide Applications
Author: Shawn Butler, Graduate Research Assistant No Comments

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

Think before pulling the trigger
Author: Scott Stewart, IPM Extension Specialist No Comments

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

WEATHER HAMPERS WHEAT HARVEST; COTTON NEEDS HEAT UNITS

Weather continues to take a toll on Tennessee crops. Some fields have been planted multiple times because of standing water and, in some areas, wheat is still standing due to wet fields. Rains have cooled temperatures, which has a negative effect on the cotton crop through a decrease of needed heat units. Continue reading at Crop Progress 7 13 14 .

2014 Growing Degree Days as of July 12
Author: Tyson Raper, Cotton & Small Grains Specialist Comments Off

2014bloomBlooms are beginning to become easier to find in West TN cotton fields. It appears first bloom (the period in which 50% of plants have begun flowering) has arrived roughly 7-14 days behind schedule. Our plots here and around Jackson have definitely jumped in the past few days with warmer temperatures and moderately clear skies. Still, the 7 day forecast looks more like May. With that in mind, I’ve collected and graphed the growing degree days (no cut-off temp, base 60) in Jackson, TN for the past 14 years. Continue reading

Current Options for Plant Bug Control in Cotton
Author: Scott Stewart, IPM Extension Specialist Comments Off

Many consultants are reporting a real upswing in tarnished plant bug numbers in cotton this week. This includes our own cotton here in Jackson. Much of the cotton is at bloom, plus or minus a week, and tarnished plant bugs appear to be just about the only pest in most fields. A few people have reported seeing some brown stink bugs, but I’m not too worried about them until this cotton has a few more bolls on it. The common question has been … what should I spray? Below I’ve listed some options with Continue reading
