A New Tool For Improving Thrips Management in Cotton<\/a><\/h2>\n

By Phillip Roberts on Mar 21, 2018\u00a0<\/em>
\nThrips are the most consistent insect pest of cotton in Georgia and the Southeast.\u00a0 Near 100 percent of the cotton planted will be infested by thrips each year.\u00a0 For this reason preventive insecticides applied as a seed treatment and\/or an in furrow application at planting are recommended.\u00a0 At-plant insecticides for thrips control provide a consistent yield response.\u00a0 Thrips infestations in cotton vary by location, planting date, and year.\u00a0 In some situations (high thrips infestations and\/or slow seedling growth) supplemental foliar insecticides may be needed in addition to at-plant insecticides.\u00a0 Foliar insecticides are recommended when 2-3 thrips per plant are counted and immatures (cr\u00e8me colored and wingless) are present.<\/p>\n

Thrips injury on seedling cotton is a function of thrips pressure and seedling growth.\u00a0 Seedlings are most susceptible to thrips feeding during early growth stages; economic damage rarely occurs once seedlings reach the 4-leaf stage and are growing rapidly.\u00a0 Thrips injury is more severe when seedlings are not growing rapidly (i.e. stress from cool temperatures or herbicides); rapidly growing seedlings can better tolerate thrips feeding.<\/p>\n

A new tool,\u00a0Thrips Infestation Predictor for Cotton (TIPs)<\/strong>, is available to aid growers in thrips management decisions.\u00a0 Entomologists from the southeast cooperated with researchers at North Carolina State University who developed the TIPs tool.\u00a0 Data from Cotton Commission funded projects evaluating thrips management programs by planting date were used to aid in the creation of and to validate the tool.\u00a0 Additionally, county agents collected thrips infestation data from over 300 commercial fields during 2016 and 2017 as part of the TIPs tool verification effort.<\/p>\n

The TIPs tool uses planting date, temperature, precipitation, and knowledge of when and how intense thrips infestations will be to predict risk of thrips injury to cotton.\u00a0 The TIPs tool can be used to identify planting dates which are at greatest risk for thrips injury.\u00a0 The TIPs tool will give the best predictions within 10-14 days after you use it, so use at multiple times during the planting and thrips management season would be beneficial.\u00a0 Dr. George Kennedy has prepared the webinar \u201cThrips Infestation Predictor for Cotton: An Online Tool for Informed Thrips Management\u201d.\u00a0 The webinar includes an overview and how to use\u00a0the TIPs tool and can be found at\u00a0https:\/\/www.plantmanagementnetwork.org\/edcenter\/seminars\/cotton\/ThripsInfestationPredictor\/<\/a><\/p>\n

High risk planting dates will require more aggressive thrips management compared with low risk planting dates to achieve acceptable thrips control.\u00a0 Management options for high risk planting dates would include the use of in-furrow liquid insecticides such as acephate, imidacloprid, or aldicarb or the use of a neonicotinoid seed treatment plus a supplemental foliar application at the 1-leaf stage.\u00a0 In low thrips risk environments neonicotinoid seed treatments will generally provide acceptable control.\u00a0 The TIPs tool should allow proactive decisions to be made relative to thrips management.\u00a0 The Thrips Infestation Predictor for Cotton tool can be found at\u00a0https:\/\/climate.ncsu.edu\/CottonTIP<\/a>.<\/p>\n
