7/25/2015 – Cotton is fruited nicely and is under control on plant bugs. We are getting a fairly large influx or worm moths and eggs, with some worm under stuck blooms. This is prompting us to recommend combination doses of insecticide that include a phosphate and a pyrethroid to control both plant bugs and worms. We are seeing a little red spider in places, and aphids have not been a problem so far.
Milo is beginning to get infestations of sugarcane aphid, and there have been some combination midge and aphid doses go out. There are some fields, however, that have not reached treatment levels of aphids. The milo crop, so far, looks good. We have used on midge either Blackhawk or a pyrethroid and have been pleased with both. Aphids are receiving treatment of either Transform or Sivanto.
Soybeans have had only a few fields reach treatment levels of stink bugs or bean leaf beetles. Many fields received the R3 dose of fungicide and insecticide. Green clover worms have been the predominant looper, but leaf loss has been minimal.
Rice fields are beginning to head in the older fields, with some fields showing tanning of the heads. Some of the fields that headed first received insecticide doses for rice stink bugs, but not all fields have met treatment levels. Varieties other than hybrids will be receiving a fungicide dose at boot split for blast, sheath blight and kernel smut. Sheath blight has been light so far this year in my area.
Older corn was receiving their last irrigation the first part of the week, but rains were prevalent toward the end of the week. We found only a few fields of corn with southern rust. The corn crop looks good over all.

7/24/2015 – Milo – spraying the later milo for head worms – older milo will desiccate first of the week.
Soybeans – have received some much needed rain, but where we missed beans are headed south fast. Late beans that are R 3.5 have threshold of boll worms, and we are spraying those. Wheat beans aren’t blooming yet, and we are still applying weed control measures. Using Roundup, Blazer, and Zidua on most of these for lay by.
Cotton – latest cotton with 14 nodes and starting to bloom – oldest with 20 nodes and 5-6 NAWF. Plant bugs, aphids and worm eggs have been our latest problem. Finding scattered mites, mostly on edges. Cotton looks good where irrigated or caught a rain lately. Still have dry spots where cotton is cutting out. Overall my cotton is two weeks later than normal.
Peanuts – insects have been low, we caught a rain this week right after our second white mold shot. We are about 80 days.
Corn – most corn has reached black layer with good moisture. Still have small acreage that will need more irrigation probably – two more weeks.

7/25/2015 – Soybeans-range anywhere from R2 full bloom to Late R6 early R7. Spraying for bollworms in Younger beans and stink bugs in older beans. Close to termination on irrigation on some of the earliest fields. We’re still cleaning up weeds and grasses, mostly where there were canopy issues. No weed control better than shade!!
Rice-ranges from 2nd mid-season shot to fully headed. Applied fungicides and stink bug sprays. Cleaned up the last bit of weeds and grass escapes within the last week or two.
Grain Sorghum-is fully headed in the milk to dough stage recently sprayed for head worms and sugar cane aphids.
Corn- irrigated most all for the last time and terminated irrigation on most by now. At or close to the black layer with the exception of a few late fields.

Cotton is from 15th node to cutout. Some fields have been sprayed form worms over the weekend. Spider mites are picking up in some fields with treatments being made where needed. Dry, hot weather is hurting more than anything right now. Cotton in two counties around Hattiesburg have received much needed rains over the past several days. Counties on the west side are really getting in trouble. Bugs have been light but lack of rain has hit those areas hard.
Peanuts are from 32-89 DAP. Peanuts for the most part are looking really good. Disease is still almost nonexistent. Insects are light also.
Corn is drying down and hopefully harvest will start in 2 weeks.
Soybeans are suffering on most acres I look at. If they are not irrigated, they are stressed right now. Rain chances increase at the end of this week and hopefully will come.

7/28/2015 – Earliest planted soybeans are at R6+ and safe from insect and disease and are being watered for the last time this week. Later planted beans have been treated for bollworm, loopers and stinkbugs using 7oz. Besiege plus 1gal to 100 a. Lambda-Cy.
I’ve not been bothered by midge in milo this year but have had heavy numbers of armyworms, bollworms and webworms. Treated these acres with Besiege and we’ll see if sugarcane aphids are flared.
We’ve had moderate numbers of plant bugs, as usual and have been able to keep them under control with pyrethroid plus acephate on a 12-14 day interval. Applied ¾ oz. Transform plus .75# acephate where plant bugs and aphids were present. Where spider mites are a concern, we’ve used Portal and Abamex – Portal performed better but more costly. Cotton is fruited well. Who know what these high temps have done to quality.
Have applied one white mold app of Abound in peanuts earlier and Tilt and Bravo for leaf spot. On the next while mold treatment, I’ll use Abound on half of acres and Convoy on the other half.
We’ve had no rain since July 4th.

7/28/2015 – Cotton growth stages range from 1st bloom to cut-out. Oldest cotton continues to have pressure from worms, eggs, spider mites and plant bugs. Overall, older cotton is good but too early to tell on the late planted crop.
We’re terminating some soybean acres this week and have treated some of the later planted acres for bollworms and stink bugs. Frogeye is showing up and we’re treating some acres where only a single fungicide was used earlier. Irrigation is going wherever possible.
Most corn acres have been terminated except for 2 fields that I’ll continue to check for a couple of more weeks. They’ll probably start cutting some samples mid to late next week in this area.
Aphids have been light all year in milo. The oldest is approaching black layer. The late planted milo is heading sporadically and we’ll probably have to treat late season.
