Grower adoption of insecticide resistance management practices increase with extension‐based program

Abstract

Implementation of the IRM education program was successful, as adoption rates of both practices increased within 3 years. Growers were surprisingly most receptive to adopting these practices to mitigate insecticide resistance as opposed to saving money. Developing extension-based programs that involve regular and interactive meetings with growers may significantly increase the adoption of IRM and related integrated pest management tactics. © 2018 Society of Chemical Industry.

Management of Onion Thrips (Thrips tabaci) in Organic Onion Production Using Multiple IPM Tactics

“…The replacement of "Bradley" with a lower yielding thrips-resistant cultivar is not likely to be adopted by onion growers unless fewer insecticide applications are required to protect it against T. tabaci. Ideally, resistant cultivars should reduce onion thrips densities below action thresholds, thereby reducing the number of insecticide applications applied throughout the season [42,49]. In our studies, the mean season densities of onion thrips larvae in the semi-glossy cultivars were above 3 larvae/leaf in 2018 and above 10 larvae/leaf in 2019.…”

“…Spinosad (Entrust ® , Corteva Agriscience, Indianapolis, IN, USA), produced from a soil-inhabiting actinomycete bacterium, Saccharapolyspora spinosa [45], is one of the most commonly used biopesticides for managing insect pests in organic vegetable production and is effective against several onion insect pests [46][47][48]. Spinetoram (Radiant ® , Corteva Agriscience, Indianapolis, IN, USA), spinosad's conventional counterpart, is arguably one of the most effective active ingredients for managing T. tabaci in conventional onion production throughout the northern US [1,2,49]. Few other OMRI-listed biopesticides have shown promise for reducing T. tabaci densities in onion [48,[50][51][52].…”

Indoxacarb‐loaded fluorescent mesoporous silica nanoparticles for effective control of Plutella xylostella L. with decreased detoxification enzymes activities

“…In view of this, insecticide resistance management (IRM) strategies are sorely needed to efficiently mitigate the development of resistance or reverse insecticide resistance 4 . Conventional IRM strategies, consisting of rotation of chemical classes, using thresholds, and other non‐chemical control measures, are proposed to maintain the profitability and stability of agricultural production systems 5 . The goal of these tactics is to reduce the selection pressure of a given active ingredient on an insect pest or to avoid selection of resistance mechanisms 6,7 .…”

Soil conservation practices for insect pest management in highly disturbed agroecosystems – a review

“…Currently, near exclusive reliance on a limited number of existing insecticides has led to resistance and reduced efficacy. Insecticide resistance is a major issue and developing strategies to manage it is increasingly a priority for Colorado potato beetle (Alyokhin et al, 2013a;Huseth et al, 2014), green peach aphid (Srigiriraju et al, 2010), and onion thrips (Shelton et al, 2003;MacIntyre Allen et al, 2005;Leach et al, 2018b). The addition of alternative management strategies would reduce the frequency of pesticide applications necessary to attain adequate control.…”

“…Although insecticides continue to be relied upon for onion thrips control, efforts to reduce insecticide use have been encouraged through the adoption of action thresholds and thrips-resistant cultivars (Nault & Huseth, 2016;Leach et al, 2017). In New York, onion growers have substantially increased their adoption of action thresholds and rotation of insecticide classes with the primary goal of mitigating insecticide resistance development in onion thrips populations (Leach et al, 2018b).…”
