Field operations such as herbicide applications can continue as normal.<\/p>\n<div class=\"content-block\">\n<p><a href=\"https:\/\/growiwm.org\/what-is-precision-weed-management\/\" target=\"_blank\" rel=\"noopener\"><strong>Precision or target sprayers<\/strong>,<\/a> which use cameras to detect and spray weeds, are a good way to take advantage of weeds corralled into a chaff line. Ongoing research is examining potential for herbicide product savings using these sprayers in chaff-lined fields.<\/p>\n<p>Ideally, every harvest places the chaff line on top of the previous harvest\u2019s chaff line, as would be done in controlled traffic farming. Since weed seeds can remain viable and germinate for several years, putting each season\u2019s chaff lines in the same spot avoids rows of weed seeds from different harvests.<\/p>\n<p><strong>Check out these farmers\u2019 experiences:<\/strong><\/p>\n<ul>\n<li><strong><a href=\"https:\/\/growiwm.org\/eastern-shore-farmer-tries-chaff-lining-to-defeat-weeds\/\" target=\"_blank\" rel=\"noopener\">Eastern Shore Farmer Tries Chaff Lining to Defeat Weeds<\/a><\/strong><\/li>\n<li><strong><a href=\"https:\/\/growiwm.org\/making-chaff-lining-work-on-shepherd-grain-farms\/\" target=\"_blank\" rel=\"noopener\">Making Chaff Lining Work on Shepherd Grain Farms<\/a><\/strong><\/li>\n<\/ul>\n<\/div>\n\t\t\t\t\t\t\t\t\t<\/div>\n\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\n\t\t\t\t\t\t\t<\/div>\n\t\t<\/div>\n\n\t<\/div>\n<\/section>\n<div class=\"wp-block-classic\"><div class=\"max-width-row\">\n\n<\/div><\/div>\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n<div class=\"wp-block-classic\"><div class=\"max-width-row\">\n\n<\/div><\/div><div class=\"wp-block-paragraph\"><div class=\"max-width-row\">\n<p>For an expanded overview of all harvest weed seed control methods, return to the <a href=\"https:\/\/growiwm.org\/how-harvest-weed-seed-control\/\" target=\"_blank\" rel=\"noreferrer noopener\"><strong>Harvest Weed Seed Control page<\/strong><\/a>.<\/p>\n<\/div><\/div><div class=\"wp-block-classic\"><div class=\"max-width-row\">\n\n<\/div><\/div>\n<div style=\"height:24px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n<div class=\"wp-block-classic\"><div class=\"max-width-row\">\n\n<\/div><\/div><div class=\"wp-block-paragraph\"><div class=\"max-width-row\">\n<p><strong>Authors<\/strong><\/p>\n<\/div><\/div><div class=\"wp-block-classic\"><div class=\"max-width-row\">\n\n<\/div><\/div><div class=\"wp-block-paragraph\"><div class=\"max-width-row\">\n<p>Michael Flessner, Virginia Tech<\/p>\n<\/div><\/div><div class=\"wp-block-classic\"><div class=\"max-width-row\">\n\n<\/div><\/div><div class=\"wp-block-paragraph\"><div class=\"max-width-row\">\n<p>Eli Russell, Virginia Tech<\/p>\n<\/div><\/div><div class=\"wp-block-classic\"><div class=\"max-width-row\">\n\n<\/div><\/div><div class=\"wp-block-paragraph\"><div class=\"max-width-row\">\n<p>Emily Unglesbee, GROW<\/p>\n<\/div><\/div><div class=\"wp-block-classic\"><div class=\"max-width-row\">\n\n<\/div><\/div><div class=\"wp-block-paragraph\"><div class=\"max-width-row\">\n<p><strong>Editors<\/strong><\/p>\n<\/div><\/div><div class=\"wp-block-classic\"><div class=\"max-width-row\">\n\n<\/div><\/div><div class=\"wp-block-paragraph\"><div class=\"max-width-row\">\n<p>Claudio Rubione, GROW<\/p>\n<\/div><\/div><div class=\"wp-block-classic\"><div class=\"max-width-row\">\n\n<\/div><\/div><div class=\"wp-block-paragraph\"><div class=\"max-width-row\">\n<p>Mark VanGessel, University of Delaware<\/p>\n<\/div><\/div><div class=\"wp-block-classic\"><div class=\"max-width-row\">\n\n<\/div><\/div><div class=\"wp-block-paragraph\"><div class=\"max-width-row\">\n<p><strong>Reviewers<\/strong><\/p>\n<\/div><\/div><div class=\"wp-block-classic\"><div class=\"max-width-row\">\n\n<\/div><\/div><div class=\"wp-block-paragraph\"><div class=\"max-width-row\">\n<p>Breanne Tidemann, Agriculture and Agri-Food Canada<\/p>\n<\/div><\/div><div class=\"wp-block-classic\"><div class=\"max-width-row\">\n\n<\/div><\/div><div class=\"wp-block-paragraph\"><div class=\"max-width-row\">\n<p>Lovreet Shergill, Colorado State University<\/p>\n<\/div><\/div><div class=\"wp-block-classic\"><div class=\"max-width-row\">\n\n<\/div><\/div>\n<div style=\"height:23px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n<div class=\"wp-block-classic\"><div class=\"max-width-row\">\n\n<\/div><\/div><div class=\"wp-block-paragraph\"><div class=\"max-width-row\">\n<p><strong>Citations<\/strong><\/p>\n<\/div><\/div><div class=\"wp-block-classic\"><div class=\"max-width-row\">\n\n<\/div><\/div><div class=\"wp-block-paragraph\"><div class=\"max-width-row\">\n<p>Bennett AJ, Yadav R, Jha P.
