Volume XXVII No. 3

This will be the last newsletter that we will be able to mail to you unless you have returned the post card we sent with the first newsletter in January. If you have lost the post card but wish to remain on the newsletter, give us a call at 956-968-5581 and ask for Amelia. She will then add you to the list for the 2003 season. Hope to hear from you soon.

GENERAL SITUATION: Field moisture currently is adequate to more than adequate for planting cotton and grain sorghum in most locations around the LRGV. Some pre-plant irrigations have been made to a limited number of fields which were or are going to be planted to seed corn. Reports of some fields being too wet to work equipment also have been received over the last couple of weeks.

Crop planting continued this week. Corn planting is about to wind down and sorghum planting is increasing. No additional reports of cotton planting were received this week. It is still a little early to plant cotton, especially with the predictions of more cold and possibly wet weather to come this weekend and early next week.

The overall moisture situation is considerably different than the farmers in the LRGV have seen in a number of years. The spring of 1997 was wet starting in early March and it rained until early May. This year seems to be headed in the right direction with good soil moisture both at the top and bottom sides of the soil profile.

Boll weevil activity remains. Weevils have been reported in traps from all across the LRGV and likely will continue to do so until cotton begins to reach squaring stage. During periods of cool weather, similar to what we just experienced, weevil numbers will be low. Warmer periods such as Monday and Tuesday of this week will see higher captures of weevils.

If you are aware of old cotton stalks near your operations, you still should try to eliminate them. Call the Texas Department of Agriculture or talk to the neighbor whom you know has the stalks in his field and try to get them destroyed. Even at this late date, removal of those stalks will help since it is still at least two months before general cotton plantings will have squares. So, if possible, clean out the old stalks to lower the number of weevils that will go to newly squaring cotton. In short, there is never a bad time to remove old cotton stalks, it is just that destruction of stalks immediately after harvesting still is the best timing because it does the most damage to boll weevils.

PEST CAST continued

Bollworms could also be on the increase this season. The same rain clouds that dumped all of the moisture on the LRGV did the same in northern Mexico. Mexican corn growers have more than doubled their corn acres this year. Dr. Jesus Vargas, Research Entomologist with the Rio Bravo, Mexico experiment station, has indicated that over 100,000 acres of corn have been planted in northern Tamaulipas, Mexico this spring. Corn there may result in increased bollworm moths migrating here and laying eggs in our cotton. The increased egg lays could be seen in April or slightly later depending on when the bollworms in their corn emerge as new moths this spring.

The old saying that “nothing comes for free” is certainly true with the moisture now available. Most folks we have talked to will gladly deal with any increase in insects just to be able to have the water. Certainly, no one is complaining about a few stuck tractors or other potential risks associated with good quantities of rainfall. We are all glad to have it.

Grain sorghum is up and growing all over the LRGV this week. A little sorghum was yet to be planted, but most was in the ground by the end of this week. Insect activity was very light in sorghum, but could change.

Yellow sugarcane aphids (YSA) were noted on a couple of plants in scattered sorghum fields this week. YSA can do considerable harm to very young seedling sorghum, even if only one YSA per plant is found. Young sorghum needs to be monitored to stay abreast of any changes in pest and beneficial numbers. Even though sorghum has not brought in much money, it was not planted just for the bugs either. So, keep alert for potential insect problems starting with the new plants.
