Terminating Insect Sprays in Mississippi Soybeans

DSC_0216

We are quickly approaching that time of year where some of the earlier planted fields are turning color and others are approaching R6 vey quickly. Often times many of the insect pest we deal with “pile in” about this time and growers face the tough decision to treat when it may not pay back or try and race them to the end. We have devoted a lot of time and effort in recent years to evaluate and validate thresholds in soybeans under the current growing practices in Mississippi. Through these research efforts we have made several changes to insect thresholds and termination points for insect pest of soybeans in MS. . . . → Read More: Terminating Insect Sprays in Mississippi Soybeans

2014 Preliminary Side Inlet/Intermittent Irrigation Results

This week I thought I would share with you the progress of our rice irrigation studies. This summer we have three producer “on farm” irrigation trials. Each producer agreed to irrigate his field conventionally through levee gates, via side inlet, and an additional side inlet utilizing intermittent flood. The producer originated irrigation on the conventional and . . . → Read More: 2014 Preliminary Side Inlet/Intermittent Irrigation Results

Bollworms in Dual Gene Bt Cotton: Control and Expectations

DSC_0056

Over the last 7 days we have had numerous reports of high bollworm numbers in some BollGard II, TwinLink, and WideStrike fields in the Mississippi Delta. We have seen fields in the past that reach treatable levels but some reports are much higher than we have seen in recent years. At this time there does not appear to be any specific varieties that are adversely affected more than others. It appears to be a function of high pressure in isolated areas at this time. . . . → Read More: Bollworms in Dual Gene Bt Cotton: Control and Expectations

Insect Trap Counts, August 14, 2014

After 4 weeks of high bollworm moth catches averaging more than 75 moths/trap/week, this week has dropped down to an average catch of 35 moths/trap. This should mean that once current worm populations are controlled, a substantial reinfestation is not likely. However, tobacco budworm moth catches did not go down much this week, so late soybeans and non-Bt cotton could have mixed . . . → Read More: Insect Trap Counts, August 14, 2014

When is it safe to Apply a Grain Sorghum Harvest Aid and what to Expect?

Sorghum Heads

Many growers in the Mid-South apply a herbicide shortly prior to sorghum harvest to facilitate combine efficiency and suitable grain moisture. This season, this issue is even more critically important because of severe harvest problems potentially created by White Sugarcane aphid infestation. This article will discuss appropriate timing and potential outcome of such harvest aid applications.

Insect Trap Counts, August 8, 2014

Bollworm trap counts continue to be high in the Delta for the fourth consecutive week. Tobacco budworm counts are also fairly high in the Delta. However, the traps in the hills did not indicate as much pressure. Continue to be alert for damaging pressure from these insects in sensitive crops throughout . . . → Read More: Insect Trap Counts, August 8, 2014

Last Effective Bloom Date in Cotton

The last effective bloom date is the last date that a white flower will accumulate enough heat units to mature into a harvestable boll.  Generally speaking it takes 850 heat units for a white flower to mature into a harvestable boll.  Using 30-year historical weather data from the National Climatic Data Center, the last effective bloom . . . → Read More: Last Effective Bloom Date in Cotton
