Nodes Above White Flower

Counting Nodes Above White Flower (NAWF) is a good way to monitor a cotton field’s maturity after bloom. The process is done by finding the first position white flower and counting the number of nodes (branches) above the branch with the white flower. The last node to count is the highest node with an unfurled main stem leaf (at least 1-inch wide). NAWF is useful for management of your cotton crop. By tracking NAWF, you can see how the crop is maturing compared to an expected growth curve. … Read More →

Pest Update and 2020 Insect Thresholds

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 →
