Due to the widespread adaptation of the Roundup Ready technology and subsequent overuse of only glyphosate for weed management, confirmation of weed resistance to glyphosate takes the battle to an entirely different level. For several years, producers in Louisiana were fortunate to watch glyphosate resistance issues with Palmer amaranth played out in articles of Delta Farm Press regarding neighbors to the north in Mississippi, Tennessee, and Arkansas. The old adage Mother Nature Always Wins has unfortunately proven true again and resistance cases have been confirmed to glyphosate here in Louisiana. The majority of parishes in Northeast and Northwest Louisiana boarding the Mississippi and Red Rivers, as well as St. Landry Parish, now have documented cases of glyphosate resistant Palmer amaranth. Seed from resistant populations in neighboring states is carried along these main waterways and distributed in adjacent fields with back water flooding and seep water in spring. Three characteristics that make glyphosate resistance in Palmer amaranth such a problem are a very aggressive growth habit, tremendous seed producing capability, and a 73% germination rate. In our perfect growing conditions in mid to late summer, it is not uncommon to see Palmer amaranth plants put on 8 to 10 inches of growth in a week s period and produce viable seed. Studies in Arkansas have shown that female plants are capable of producing up to 1.77 million seed. At that rate, managing the weed becomes a numbers game. Take for instance an area with 50 female plants that each produce 500,000 seed. Let s say that 90% of those seed are lost to predation or rot or other means. Also, let s say a producer implements a management strategy that provides 99% control. He/she is still left with million seed. With a 73% germination rate, that means there is a potential to have 3.63 million plants, each capable of producing 1.77 million seed!!!

2 Page 2 The main recommendation for preventing introduction of or managing an established population of glyphosate resistant Palmer amaranth is to start clean with a planned rotation of herbicides that are effective on the weed species and offer a completely different mode of action, or means of controlling the weed, than glyphosate. Switching from Roundup Powermax to Touchdown or Glyfos Xtra does no good as all are glyphosate products. In corn, products like Callisto, Laudis, or products that contain atrazine are effective on Palmer amaranth and offer a differing mode of action that is not available in soybean or cotton. In soybean, a number of products are effective soil applied on Palmer including Prefix, Boundary, Authority MTZ, Valor SX, Envive, Valor XLT among others. In cotton, programs including preplant applications of Valor SX, Reflex, or Direx coupled with at planting application of Cotoran, Caparol, or Prowl have been proven effective on Palmer amaranth. A number of postemergence options are also available within each crop. Effective options for control of Palmer and other pigweed species are listed in the Louisiana Suggested Chemical Weed Control Guide which can be accessed at communications/publications/management_guides/louisianas+suggested+chemical+weed+control+guide.htm. An effective strategy for management of this weed is to overlay residual herbicides to never let the weed off the mat. This includes application of residual herbicides preplant, at planting, in early season over-the -top applications, and at layby. You always want an effective material present at peak strength when another is playing out. This will ensure season long control of the weed. Liberty 280 SL herbicide, used within the Liberty Link system and offering a different mode of action to glyphosate, is effective on pigweed species, including Palmer, if applied to very small weeds 1 inch or less. Control of pigweed 2 to 4 inches can be somewhat erratic. Addition of residual herbicides mentioned before at planting or included with Liberty in early over-the-top applications (Dual Magnum, Staple LX etc.) are needed for season long control. Since Palmer amaranth has a light requirement for germination, burial of the seed utilizing deep tillage can prove effective in its management. Germination and soil life are drastically reduced with seed burial of depths 2 inches are greater. Re-hipping of row following deep tillage, however, negates this advantage by bringing seed up to light exposure and subsequent germination. Prevention of seed production after removal of the crop is also essential to prevent replenishment of the seed bank. Utilize whatever means necessary, be it hand rouging, tillage, or herbicides to prevent plants from producing seed. Also remember that Palmer amaranth seed can be carried by equipment between fields so make sure it is thoroughly clean prior to entering/exiting fields, especially if custom harvesting is being utilized. Another area to manage Palmer amaranth is on field turn-rows and ditch banks surrounding fields. Allowing Palmer amaranth to grow on turn-rows and ditch banks and produce seed is an excellent way to infest the field. Therefore, if Palmer amaranth is present on a turn-row prior to planting, the turn-row needs to be either tilled or paraquat should be applied to control it. For best management, a soil-applied residual herbicide, such as the one a farmer will be applying to the field for Palmer amaranth management, should be tank-mixed with the paraquat. Palmer amaranth management on a ditch bank is not as easy because of aquatic restrictions for many herbicides that are effective for Palmer amaranth control. Herbicides that can be applied in aquatic situations, such as diuron and diquat, are alternatives for management of Palmer amaranth on ditch banks. However, be sure to read the label to verify that a herbicide is labeled for use on in these situations. Devastating effects of glyphosate resistant Palmer amaranth are many and include loss in value of the technology on your farm, possible decreased land value, outright field abandonment, and increased production costs due to incorporation of additional herbicides and tillage needed for successful management of the weed. In other words, all of the benefits associated with the Roundup Ready technology such as reduced herbicide use, reduced tillage, faster applications, are no longer realized. Therefore, use all available tools to prevent this problem from causing you to have to fight the battle within the battle.

All information in this table was provided by the seed companies or the University of Arkansas variety testing program at The soybean cyst nematode (SCN) is considered to be a minor nematode in Louisiana at this time. There appears to be very little need to select varieties that have resistance against this nematode. Root-knot and reniform nematode appear to be the major nematode pests in soybean. Root-knot nematode is common in coarse-textured soils such as sandy loams, loams, and silt loams. Reniform nematode prefers finer-textured soils and occurs in the highest populations in the silt loams and silty clay loams. Unfortunately, there are very few varieties on our recommended list that have either rootknot or reniform resistance. Peanut and grain sorghum are recommended resistant crops to rotate to help manage root-knot nematode. Corn, grain sorghum, and peanuts are good rotational crops to manage reniform nematode.

8 Early Season Thrips Control in Cotton Sebe Brown Extension Entomologist Dr. David Kerns Research and Extension Entomologist Thrips are annual pests of cotton in Louisiana. Damage by these pests can cause stunted growth, delayed plant maturity and plant death under heavy infestations. Cotton is most susceptible to thrips from emergence to the 3-4 leaf stage. Once cotton has reached the 3-4 leaf stage, terminal bud growth is accelerated and plants become less susceptible to injury. The most common thrips found in Louisiana cotton are tobacco thrips, eastern flower thrips, onion thrips and western flower thrips. These insects overwinter on a variety of weed hosts and having clean ground when planting can help reduce the severity of early season thrips infestations. Planting seasons with windy conditions can have considerable influence on the severity of thrips populations in early cotton. Cotton fields planted in cooler, adverse growing conditions may also be more susceptible to cotton planted in warmer, optimum conditions. Additionally, preplant, pre-emergence, and early-post herbicide applications that may stunt plant growth and may also exasperate thrips injury. With the loss of Temik, insecticide seed treatments (ISTs) and over-sprays will be important for controlling thrips in seedling cotton. Cotton seed comes with a variety of seed treatment options that may either be purchased through a seed company or applied by a dealer downstream. Outlined below are a few options with regards to insecticide seed treatment packages in cotton. Dow s Phytogen seed comes with a base package of thiamethoxam (Cruiser), with Avicta Complete Cotton available upon request. Avicta Complete Cotton comes with Cruiser for the IST, multiple fungicides and abamectin for nematode control. Monsanto s Deltapine cotton seed comes with a base package of imidacloprid (Gaucho) and several fungicides that fall under the Acceleron treatment umbrella. Producers also have the option of upgrading to Avicta Duo Cotton with Cruiser for insect control, several fungicides for disease control and abamectin for nematodes. Bayer s Stoneville/Fibermax cotton seed comes with a base package that includes Gaucho for insect control and thiodicarb for nematodes that falls under the Aeris treatment umbrella. Producers also have the option to upgrade to Poncho/Votivo with clothianidin (Poncho) for insects and Bacillus firmus (Votivo) for nematodes. Another option is to purchase base-treated seed and have a dealer treat the seed downstream. Insecticide seed treatments offer some early season protection from thrips, however, these treatments will only offer 2 to 3 weeks of control. Control failures can occur with at-plant treatments and cotton should be frequently scouted for thrips until the four leaf stage. Don t wait for the evidence of damage to initiate foliar sprays, but look for the appearance of immature

9 thrips as an indicator of seed treatment failure. Look closely through the terminal leaves, while also unfolding the small leaves; alternatively, pull plants and shake them vigorously in a plastic Solo cup and look for dislodged thrips. Immature thrips appear as small light yellow cigars shaped insects Last year, western flower thrips were a problem in fields around the state. Western flower thrips are typically amber, yellowish-brown to dark brown in color. Seed treatments may fail sooner when western flower thrips are prevalent and foliar treatments are generally less effective. Last year s data suggests that when western flower thrips are present, Acephate at 8 oz provided the best control followed closely by Radiant at 1.5 oz + a surfactant and Bidrin at 3.2 fl-oz. Keep in mind that early applications of acephate may flare mites and aphids. Additionally, these treatments will only provide 4-7 days of control so follow-up sprays may be required. For more information concerning insect pest management, contact your local LSU AgCenter parish agent or LSU AgCenter specialist.

10 Influence of Hybrid, Plant Population, Fertilizer Nitrogen Rate, and Nitrogen Timing on Corn Yield Performance on Mississippi River Alluvial Clay H.J. Rick Mascagni, Jr. Introduction The cost of producing corn has increased dramatically over the last few years. Much of this increased cost has been associated with higher fertilizer nitrogen (N) and seed costs. Optimum N and seeding rate depends on many factors including hybrid, yield potential, soil type, and soil moisture status. Higher seeding rates and N rates are generally needed at higher yield potentials. Supplemental N applied late in the growing season may be required some years, depending on growing conditions. Another important factor is hybrid genetics. Seed companies are developing hybrids with higher and higher yield potential that may require more N and higher seeding rates. To maximize yield potential and profitability, more information is needed on N requirements and optimum seeding rate for the commercial hybrids currently being marketed. Procedures Field experiments were conducted in 2012 on Sharkey clay at the Northeast Research Station near St. Joseph to evaluate the influence of plant population and N rate on two corn hybrids. Supplemental N rates at early silk were also evaluated. Two hybrids, five plant populations, four early-season N (ESN), and two late N rates were evaluated. Hybrids evaluated were Dekalb DKC64-69 and REV 28HR20. Seeding rates were 26,400, 30,800, 35,200, 39,600, and 44,000 seed/acre with targeted plant populations of 24,000, 28,000, 32,000, 36,000 and 40,000 plants/acre. Seeding rates were increased approximately 10% greater than the targeted population. Seeding rate treatments were planted with a John Deere 1700 precision planter. Additionally, the 26,400 seeding rate treatment was planted with a cone planter for evaluating the influence of spacing on corn yield. ESN rates evaluated were 180, 210, 240, and 270 lb/acre. Nitrogen was knifed in using solution at approximately the 2-leaf growth stage. Late N rates of 0 and 60 lb/acre were broadcast applied using granular at early silk. The trial was furrow irrigated, including an irrigation after applying the late N. The trial was planted April 9. Cultural practices as recommended by the LSU AgCenter were followed. Experimental design was a randomized complete block with a split-split plot arrangement of treatments and four replications. Main plot was late N, split plot hybrid, and split-split plot seeding rate. Measurements included grain yield (machine harvested two center rows of four-row plots), which is reported at 15.5% moisture, and yield components, ears/acre, seed weight, and kernels/ear. NDVI readings were collected with a Greenseeker May 8 (seven-leaf growth stage). Seed nutrient analyses (N, P, K, S, and Zn) were conducted by the SPESS lab. Seed nutrient uptake was calculated by multiplying seed nutrient concentration by yield. Plant population was determined just prior to harvest. Statistical analyses were performed using the GLM procedure of SAS at probability level of 0.10.

11 Results and Discussion Rainfall was below normal in April through June (Table 1), resulting in five furrow-irrigations in May and June. Even though planting date was relatively late (April 9), yields were excellent with all but one seeding rate treatment averaging over 200 bu/acre (Table 2). Except for the lowest seeding rate of 26,400, harvested plants/acre were close to the targeted plant population (Table 2). Maximum yield occurred at the lowest plant population, 28,400 plants/acre. Optimum plant population may have been even lower for the two hybrids evaluated, since both have the flex-ear developmental trait. The largest yield difference occurred for the 26,400 seeding rate planted with the precision planter, John Deere 1700, and the cone planter (213 versus bu/acre). The lower yield for the cone planter treatment was probably due to increased variability in plant spacing. Measurements evaluating plant spacing were not taken, but NDVI readings at the seven-leaf growth stage suggested that there was a difference in the uniformity of plant spacing (Table 3). The influence of ESN and late N rates on corn yield averaged across seeding rates is presented in Table 4. There was a significant yield response to late N for each ESN rate and hybrid. Yield response to late N (red numbers in parentheses) decreased as ESN rate increased, as evidenced by a significant ESN x late N interaction for yield. Although the hybrid x ESN x late N rate for yield was not significant, REV 28HR20 tended to respond more to late N than did DKC Optimum N rate (total N) was about 270 lb/acre for DKC and 300 lb/acre for REV 28HR20. In Table 5, both the concentration and total uptake of seed N, P, K, S, and Zn are presented. ESN and late N consistently increased seed N concentration and uptake in both hybrids. ESN and late N also affected the concentration and uptake of other nutrients evaluated. Table 1. Rainfall in St. Joseph, Month Rainfall inches April 2.7 May 1.2 June 2.3 July 4.9 August 7.8
