Stink Bugs in Grain Sorghum

Posted on by

The Stink Bug is a primary insect pest of grain sorghum from bloom until hard dough. The insect feeds directly on the seed, reducing seed weight and yield. The most common stink bug in grain sorghum of the Mid-Coast is the Rice Stink Bug. Scout sorghum after bloom using a small bucket and beat heads into the bucket and see what is being captured in the bucket. Look here for a brief video. Economic thresholds (ET) have been evaluated and can be determined using tables or equations, but this… Read More →

If the water got off the field or did not stand for too many days, the crop was better off. Fields that held water are more likely to have square losses. Many of these fields have lost the larger squares leaving fruit smaller than match-head square. An example of this is shown. I removed the leaves showing the lower four squares have… Read More →

One question I have received is: “What is this rain going to do with our fertilizer?” The nutrient of greatest concern should be Nitrogen.  This is because of denitrification and the water solubility of Nitrogen. “Gaseous loss of nitrogen takes place by denitrification or ammonia volatilization. Denitrification is a process through… Read More →
