CROP UPDATE<\/strong><\/p>\n\n\n\n

Earlier planted corn<\/em><\/strong> is mature and harvest has begun this week in the county. Hope our growers have a good harvest season as we get into it. It is still wet across much of the county, but field activity is hopping in fields that growers can run equipment. <\/p>\n\n\n\n

Many things are happening now. Let’s keep a few items in mind at this time.<\/p>\n\n\n\n

As corn<\/em><\/strong> is drying down, stink bugs<\/strong> are moving from it to other crops. In cotton<\/em><\/strong>, be scouting for stink bugs and\/or damage. There is a dynamic threshold used based on week of bloom in cotton<\/em><\/strong>. When scouting, pull random sample of quarter size diameter bolls and avoid field edges. Pull 1 boll per acre, no less than 25 bolls per field. Sort bolls into 2 piles – those with external lesions and those without. Crack and inspect bolls with external lesions for internal damage (warts on the boll wall, stained seed or lint). If threshold is not met, check the remaining bolls for damage. Treat for stink bugs when the threshold is met.<\/p>\n\n\n\n

While we are talking about cotton<\/em><\/strong>, remember to be scouting in the plant canopy for foliar diseases. Conditions are right for target spot<\/strong> and areolate mildew<\/strong> to be infesting cotton fields. If allowed to progress, either of these diseases will cause premature defoliation. Timely scouting and treatment can protect the potential yield in cotton fields.<\/p>\n\n\n\n

Peanut<\/em><\/strong> growers should be on a good fungicide program for white mold<\/strong> and leaf spot<\/strong>. There are many options and fungicide programs available to growers, and a great, interactive decision tool (click to see Peanut Rx 2021<\/a>) to help, also. Growers with questions can call the Extension office for more information.<\/p>\n\n\n\n

Soybean<\/em><\/strong> rust has been confirmed in Tift, Toombs, and Burke County sentinel plots. Soybean<\/em><\/strong> producers across south Georgia are advised to use a fungicide to protect against rust if they haven\u2019t reached R6\/full seed growth stage or have not already sprayed within the last 21 days.<\/p>\n\n\n\n

We have had reports of fall armyworms (FAWs) in pastures<\/em><\/strong> and hay fields<\/em><\/strong>. Keep a regular check on fields. Treat when larval populations of these insects exceed 3 larvae per square foot.<\/p>\n\n\n\n
