Pest Update and 2020 Insect Thresholds

Posted on by

This week we have been finding low numbers on insect pests in cotton, grain sorghum and soybeans. Cotton ranges from 1/3 grown square to mid-bloom. While most fields are below threshold, we have found a few fields with 30-40 cotton fleahoppers per 100 plants. Continue to monitor for cotton fleahoppers until bloom and treat when they exceed an economic threshold of 15 per 100 plants. Blooming cotton has had significant bollworm moth flights this week but so far, egg numbers have been low. Bollworms are important pests and should… Read More →

Sugarcane Aphids Found in Sorghum

Grain sorghum fields in the Mid-Coast vary in maturity from soft/hard dough to pre-bloom. These fields should be scouted weekly for insect pests. Today, we found sugarcane aphids in fields near Bayside. While these fields are not at a level needing treatment, the population should be monitored twice weekly to ensure they don’t get out of hand. Sugarcane aphids can cause grain yield losses until a few weeks prior to harvest, but the crop is more sensitive to the aphids earlier in the season. As the sorghum grain… Read More →

Grain Sorghum Across the Board

Posted on by

Sorghum fields range in maturity from 4-5 leaf to bloom. This is the result of planting across 5-6 weeks. As a result of this we need to be on the lookout for a wide variety of insect pests. Headed sorghum should be checked for stink bugs and headworms. Scout for these pests using a small bucket, beating the heads into the bucket and count what remains. Follow this link for a brief video demonstrating how to scout sorghum after bloom. LINK My economic threshold for headworms is 1… Read More →
