“…In addition, All et al (1993) reported cotton seedlings had higher thrips densities in areas that had native winter vegetation compared with areas that had winter wheat as a cover crop. Toews et al (2010) found no differences in thrips densities between three cover crops (rye, Secale cereale L.; wheat, Triticum aestivum L.; and crimson clover, Trifolium incarnatum L.).…”

“…All et al (1992) reported that tobacco thrips densities were significantly lower in no-till treatments than in conventional till treatments. Toews et al (2010) observed that thrips densities were lower in plots managed using strip till practices compared with plots managed using conventional tillage practices. In addition, All et al (1993) reported cotton seedlings had higher thrips densities in areas that had native winter vegetation compared with areas that had winter wheat as a cover crop.…”

Several species of thrips are known to infest cotton seedlings in the United States and constitute one of the most common insect pest challenges for growers. The species complex, species abundance, extent of crop injury, and impact on lint yield varies widely across the cotton states. Cotton seedlings are most susceptible to thrips injury during the first 4 to 5 weeks after plant emergence. Feeding by thrips results in distortion, malformation and tearing of seedling leaves, reduced leaf area and plant height, reduced root growth, and injury to or death of the apical meristem, the latter of which leads to excessive vegetative branching. Plant maturity (i.e., fruit production) can be delayed and in extreme cases, losses of as much a 30 -50% of lint yield potential have been reported. To date, no varieties of cotton have resistance to thrips, so controls are based solely on insecticide applications. Treatment thresholds and control practices (e.g., insecticide seed treatments, in-furrow or foliar applied insecticides) vary widely across cotton states. This article provides a brief summary of the various species of thrips present in U.S. cotton, their plant host range and injury to cotton, a general description of thrips biology, and management practices currently available to growers.

“…Similarly, in conservation tillage plots the cotton had outgrown whatever protection was conferred by rolled rye cover; however, the taller standing rye continued to protect cotton from infestation by adult thrips. Toews et al (2010) showed that increasing density of ground cover decreased thrips infestations; these data suggest that the three dimensional structure of the standing ground cover may also play a role in thrips suppression.…”

“…The 2013 data suggested that thiamethoxam decreased immature thrips populations for the first two sample dates; however, this effect was not evident in the 2014 data. Previous studies (All et al, 1992;Bauer and Roof, 2004;Brandenburg et al, 1998;Hurt et al, 2005;Manley et al, 2003;Olson et al, 2006;Toews et al, 2010) document a decrease in thrips and virus incidence in reduced tillage systems. Here, we observed similar results in 2013 but not in 2014; however, virus incidence was very low in 2014 compared to 2013.…”

“…Increased ground cover from winter cover crops in conservation tillage systems has been shown to reduce thrips densities and feeding damage in cotton, and thrips densities and TSWV incidence in peanut (Johnson et al, 2001;Bauer and Roof, 2004;Olson et al, 2006;Toews et al, 2010). Previous studies show that conservation tillage with a rye (Secale cereale L.) winter cover crop can reduce soil compaction and increase seed cotton yield compared with conventional tillage (Bauer and Busscher, 1996;Raper et al, 2000).…”

Cover crops have been promoted for use in agricultural systems due to both environmental and economic opportunities. Cotton (Gossypium hirsutum L.) growers in West Tennessee faced challenges in 2015 and 2016 with cover crop termination management which resulted in failed cotton stands. The objective of this experiment was to determine effects of cover crop termination timing and method on cotton emergence, development, and yield. Field experiments were conducted from 2018 to 2020 in both small plot and on‐farm scenarios across West Tennessee. Cover crop termination timings consisted of an at‐planting termination, 3 weeks prior to planting, and both a broadcast and furrow‐strip termination 6 weeks prior to planting. The cover crop termination methods consisted of chemical termination, mechanical termination, and chemical + mechanical termination. At‐planting termination reduced emergence by 25% and delayed maturity of 65% of the stand relative to a 6‐week broadcast termination. Mechanical termination reduced emergence by 26% and delayed maturity of 26% of the stand relative to the chemical and chemical plus mechanical termination treatments. Thrips injury ratings were greater in cotton following a chemical + mechanical termination of the cover crop. Damage from three‐cornered alfalfa hoppers (Sissistilus festinus) was less prevalent in cotton following cover crops terminated 6 weeks prior to planting in a broadcast method compared to other timings. While early season effects were observed, end‐of‐season yield differences were not noted. Still, producers in short season environments should be aware of the higher level of risk associated with at‐planting terminations or terminations.
