Acid soils often need liming to aid crop growth and development. Fall applications provide more time for the lime to react with the soil, less stress on the human component, and better field conditions for equipment operation.
Soil acidity problems rarely have dramatic visual symptoms. Affected areas are less hardy or vigorous in growth; the size of . . . → Read More: Lime Need and Value
Phytotoxicity, associated with the application of some specific foliar fungicide products, has been observed in numerous commercial soybean fields again this season. Keep in mind that the symptoms associated with fungicide phytotoxicity will appear quite similar to sudden death syndrome (SDS). However, SDS only occurs in light soil classes. When scouting fields, keep in mind that an entire field with SDS-like symptoms might be the result of fungicide phytotoxicity, thus not a disease after all. . . . → Read More: Fungicide Phytotoxicity: Check the Fungicide Applied Prior to Blaming SDS
We have had numerous calls over the last couple weeks about small, 2-5 day old larvae, under bloom tags in Bt cotton that is near, at, or beyond cutout. All of the research done to this point suggests that cotton is safe from bollworm damage when it reaches node above white flower 5 plus 300 heat units. . . . → Read More: When to Terminate Bollworm Sprays in Late Season Bt Cotton
Bollworm pheromone catches were lower again for the second consecutive week, suggesting that once control is achieved for current larval populations, a major reinfestation is unlikely. Tobacco budworm catches were also lower . . . → Read More: Insect Trap Counts, August 29, 2014
With harvest beginning, it is time to think about the next crop. Fall liming allows time for the soil to react before the next summer crop is planted, and takes advantage of the (usually) drier conditions for field operations.
Soil pH measures soil acidity, the master variable of soil fertility. Technically pH is the concentration of hydrogen . . . → Read More: Fall 2014 Lime Programs
Plan to attend an upcoming Irrigation Termination Turnrow Talk on August 26, 2014 sponsored by the Mississippi Soybean Promotion Board, Mississippi State University Extension Service, and stakeholder organizations of the Delta Sustainable Water Resources Task Force. Soybean producers will have the opportunity to learn how to determine the right time to end irrigation for the season . . . → Read More: Reminder: Soybean Irrigation Termination Turnrow Talks – August 26, 2014
We have reached the point of the growing season where we have begun to terminate irrigation in soybean. When making this decision, the goal is to make sure that adequate soil moisture is available to ensure that the soybean seeds reach maximum size. Terminating irrigation too soon can result in decreased seed size which ultimately will . . . → Read More: Soybean Irrigation Termination
As we approach the end of August, terminating cotton irrigation is on the mind of many folks. In cotton, we recommend terminating furrow irrigation at first cracked boll. If you anticipate bolls opening in the immediate future and have been dry for some time, a final irrigation event may be in order. However, once bolls begin . . . → Read More: Cotton Irrigation Termination
This week’s bollworm trap catches were similar to slightly higher than last week, while tobacco budworm trap catches fell slightly for the week. The trap catches are typical for this time of year, so expect moderate worm pressure in all . . . → Read More: Insect Trap Counts, August 22, 2014
Bean leaf beetle numbers have been increasing steadily over the last couple weeks. We have actually made bean leaf beetle targeted sprays on a number of acres in recent days. Yield loss is caused by defoliation and less frequently by pod feeding. Bean leaf beetles were once very easily controlled by very low rates of pyrethroid . . . → Read More: Bean Leaf Beetle Numbers Picking Up in Mississippi Soybeans
