Abstract

Xyway LFR was released for use in corn as an in-furrow fungicide during 2020. Producers have raised concerns of reduced emergence and growth in corn plantings. Here we assessed the impact of Xyway LFR placement in relation to the seed for impacts on seedling emergence and growth in two contrasting soil types (sand vs topsoil) under controlled conditions. Soil was added to containers and five corn seeds were placed in a row in a furrow within each container. Xyway LFR was applied in a band at labelled rates at either 0 (directly on seed) 1.27, cm, 2.54 cm, or 5.08 cm away from the seed. Containers were maintained under a light bank and germination over time, as well as seedling biomass, was assessed. Statistical analysis indicated that plants in topsoil had greater germination rates and dry masses than plants in sand. Total plant dry masses were reduced relative to controls when Xyway LFR was placed 0 cm from the seed. However, when placed 2.54 or 5.08 cm from the seed, this impact was not evident. Potential phytotoxic effects may be mitigated by placing the product in a band at least 2.54 cm from the seed furrow.

在控制环境下，土壤类型和Xyway LFR杀菌剂的放置对玉米幼苗发芽和生长的影响。

Xyway LFR于2020年作为一种沟内杀菌剂在玉米中使用。生产者对玉米种植减少产量和生长表示担忧。在这里，我们评估了Xyway LFR放置对种子的影响，以及在受控条件下对两种不同土壤类型（沙子和表层土）中幼苗出苗和生长的影响。将土壤添加到容器中，并将五颗玉米种子在每个容器内的犁沟中成排放置。Xyway LFR在距离种子1.27、cm、2.54cm或5.08cm的0（直接在种子上）处以标记速率应用于条带中。将容器保持在光库下，并评估随时间的发芽情况以及幼苗生物量。统计分析表明，表层植物的发芽率和干物质含量高于沙中植物。当Xyway LFR放置在离种子0cm处时，相对于对照，植物总干物质减少。然而，当放置在距离种子2.54或5.08厘米处时，这种影响并不明显。通过将产品放置在距离种子沟至少2.54cm的带中，可以减轻潜在的植物毒性影响。
