Rain continues – and it could be the worst year for thrips – AgFax

Walker Cotton Technical Services, Larry Walker, Flintville, Tennessee:

“Thanks to crop rotation, cotton acres have increased a bit. Cotton harvest has started slowly. The last seven days (from June 8th) have been raining and the previous three weeks have been believed. It was too dry. I’d like to see a forecast of dryness for the next three days, but the forecast says it’s raining until Friday (June 11th). I have to dry things, so if the rain stops, I’ll be busy this weekend.

“Dr. Will McCarty has always said,” The average is just an extreme average. ” That is, the “average” precipitation for the last five weeks. It has been raining little for three to four weeks, but it has been raining consistently for the last seven to ten days.

“Due to the size of the cotton planters and their ability to cover many acres, many cottons were planted dry. The germination rates of these plants were good.

“Currently, we are concerned that 80% to 90% of cotton is in the two-leaf stage, some of which are newborn cotyledons from last week’s rain. We have to lower the thrips threshold a bit. , Thrips begin to move from larger cotton to softer cotyledonous plants. Thrips populations are not yet high, but at this point in the season they want to protect young cotton. Cotton is the first week of June. When it blooms, we begin to take the future timeline seriously. At this point, we don’t want to slow down the cotton anymore at this point in the season, as we will need a lot of rain in August.

“We are behind last year. One of the major differences last year is the rainfall in August. It usually rains about 3 inches in August, but August 2020. It rained 6 inches. It’s not two years on the same timeline. Instead of stressing whether you’re on the same path as last year, deal with the harvest in front of you. ..

“We decided to get the residual herbicide out early. In 2020, we couldn’t kill a few amaranths with dicamba, but Liberty is still working well, but weeds. I don’t want to put all the pressure on Liberty to control it. Currently, dual methachlor is used for 3 to 4 leaf cotton.

“We planted MG III beans early because it was the driest April of the five years. When the big freeze came, they were just growing to cotyledon size, but they didn’t freeze. The beans are now in bloom (June 8th) and the growers expect good prices for harvest at the end of August.

“We used the residue from burning the beans and applied an excess of herbicide. We don’t expect it to be necessary to attack them again with dicamba. This can relieve some of the pressure on dicamba. Good news that you can do.

“Corn survived the dry season and really responded to the rain of the past week. I’ve heard that it ranges from 3 inches of rain to 4 ½ inches, depending on the region.

Blake Faust, consultant for Southern Heritage Cotton, Forrest City, Arkansas:

“We all finished planting rice in May. Our cotton acres have decreased by about 20%. It ranges from between the cotyledons and the first leaves to the oldest leaves in the 7th node.

“Weather is not good this year. Rice planting has finally begun and temperatures have dropped. Some growers have postponed planting until the end of the cold season, but their acres are now better off. Seems to be growing. The cold caused some replanting. Most of the replanting was done on a flat planting floor, but the cotton planted behind the cotton is in top condition. It seems. It was a constant battle between rain, heat and the sun. Now we can really take advantage of the heat and the sun.

“We spray a lot of thrips, especially where the herbicide is depleted. The cool climate slows down the cotton a bit and is also a cause of thrips.

“The beans are in pretty good condition. Some acres haven’t been planted yet and the oldest beans are on R3. They look very good now. Some growers pick up sprayers in the fields. I’m having a hard time putting it in, but soybeans are doing well overall.

“Corn is doing great. Last night (June 7th) a storm struck Lee County and a lot of corn is tilting this morning. One of the good things about the wet ground is most of it. The corn didn’t break. Our oldest corn was just starting tassel, the youngest corn was around V2 or V3. The youngest corn was planted around May 28th.

“Rice was a challenge. Most of our rice is on heavy ground and it’s almost impossible to kill many of its grasses. Many have acquired regimental applications and some combinations and are pretty good. I’m working. It rained a few inches today (June 8th), but I have to spray fertilizer to cause a flood. To the point where I have to fertilize in the mud. Come.

“This year, the area of ​​our roller chairs has decreased, but we still have 30% of the roller chairs.

“It took some time for peanuts to settle this year, but they haven’t bloomed yet. Almost everyone is doing a pretty good job with the herbicide program. The producer was able to apply another herbicide. The peanuts are in fairly good condition. “

Richard Griffing, Griffing Consulting, LLC, Monterey, Louisiana:

“This year was terrible-it was the worst start I’ve seen. We’re wet, wet, wet, and not even planted. This is quite late for us. Probably 90% have been planted. In the last 10 days (from June 8th), half of these lands have been planted, but this rain often requires replanting. Many rice acres have been lost and cotton acres have decreased due to the inability to plant. We will have a lot of late soybeans.

“Cotton ranges from cotyledons to cotyledon squares. Most of them are in the first true cotyledon to cotyledon stage. Many people who could not plant cotton went to preventive planting this year.

“Soybeans range from unplanted to R3. Last year this time they were all R3 or R4, so this year is very late. Unfortunately, these slow-harvesting soybeans have corn earworms. You’ll see a lot. We’re starting to set up traps to monitor mo.

“The corn is pretty well. It’s all bunched and currently pollinating (June 8th). We think we’ve lost some nitrogen and we have to apply a lot of urea to maintain it. I didn’t. I lost the heat unit on a cool cloudy day, but now it looks fine.

“It has been raining 30 inches since April 7th (as of June 8th). At this point, it is probably 12 inches above the average rainfall from April 1st to the present. There are times, but it’s been raining every day for the past week. It just keeps the fields sloppy and moist. Today’s rain is unlikely, and today (June 8) is so far. It’s sunny here. You can get back to the field in a few days like this.

“One of our main problems was that we had to apply the burndown twice. Due to the short planting period, once in January or February, then about a month ago. Second time. It rains a few days after planting and the same thing happens the next week. We were late for pre-emergence chemicals, so cotton, soybeans and rice eliminate many weed control confusions. I needed. The corn was fine.

“There are a lot of milo this year, but most of them are late. It’s not good because of insect problems. It ranges from just coming out of the ground to the booting stage. This morning (June 8th) I found the first sugar cane aphid in Milo. The population hasn’t been bad so far, but it will grow rapidly. “
