Stink Bugs in Grain Sorghum

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 →

Rain and Square Loss

Scouting fields this week we are finding each field is different from the next. Much of this has to do with how the rain affected the field. 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 →

Rain and its Impact on Crop Fertility

We have received rain in great amounts over the past few weeks. This morning, my rain gauge is full, and it’s still raining. Many fields have received over 10 inches of rainfall over the past few days. 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 →
