Blacklands and Upper Gulf Coast Crop Update
|
4/9/2021 (audio file) Upper Gulf Coast dry but no significant pest problems, a few aphids and mites. Southern Blacklands very dry, corn wilting, Brazos River Bottom somewhat better. Corn leaf aphid, esp. in drought stressed corn, sugarcane aphid not found yet. Thrips abundant. Hill County; stripe rust in wheat, most acres treated, hail damage yet to be assessed. Commerce; stripe rust spraying occurring, time to spray for leaf rust. Aphids being sprayed, perhaps not needed. (6:52)
4/1/2021 (audio file) Central/Northeast Texas: Stripe rust in wheat - target flag leaf with fungicides, watch for leaf rust, wheat aphids increasing, winter grain mites still below threshold. Brazos bottom: things look good but need rain. Wharton, Jackson, Matagorda counties; crops looking good. (6:25)
2020 Episodes
7/9/2020 (external link) Cotton nearing end of season, pests very low. Sorghum: many fields harvested, others with sugarcane aphids but not at high levels, yields positive. Soybeans at R3 - R7, very few stink bugs. This might be the last recording of the season, but we will come back if pests flare up. (3:45)
7/2/2020 (external link) Pest pressure light, bollworm and stink bug locally variable. Cotton potassium deficiency and root rot. Sorghum looking good, sugarcane aphid variable. Stink bugs still below threshold in sorghum and soybean (4:22)
6/25/2020 (external link) Cotton: some at cutout, some not. Bollworm egg lay increasing, stink bugs still below threshold but numbers growing. Sorghum: sugarcane aphids common, some blooming sorghum still needs midge treatment, stink bugs still below threshold. Soybeans: stink bugs light but will increase. (5:40)
6/18/2020 (external link) Cotton: some fields over egg threshold, imidacloprid + bifenthrin not a good choice for killing eggs, stink bugs increasing. Sorghum: Some fields sprayed for midge, headworms and stink bugs increasing. Soybeans at R3 - R5, loopers present, stink bugs increasing. (4:57)
6/11/2020 (external link) Bollworm egg lay picking up, some fleahoppers in cotton, stink bugs increasing in all crops, blooming sorghum needs to be scouted for midge, sugarcane aphids increasing. (4:54)
6/4/2020 (external link) Rain, pests low in cotton and beneficials abundant; bollworm and stink bug thresholds. Grain sorghum fairly quiet, look for midge at bloom, sugarcane aphid present but not high, stinkbugs and headworms low. Blister beetles in sorghum. Soybeans, look for stinkbugs at pod fill. (7:30)
5/28/2020 (external link) Rain and soggy, extended sorghum season will pose problems, sugarcane aphids showing up, sorghum midge pending and rice stinkbugs building. Cotton; fleahoppers abundant, a few fields still susceptible; looking for bollworms and stink bugs in flowering cotton. Redbanded stink bug has a lower threshold. (8:34)
