Lesser cornstalk<br>borer LCB) is almost always found in SW Georgia peanut fields in late May, and this year is no exception.<br>Whether or not LCB populations reach damaging levels and require treatment will depend mostly on<br>temperature and precipitation over the next several weeks. Hot, dry conditions will favor LCB<br>development, while cool and\/or wet conditions will hinder populations. What should we be watching<br>most closely? If we see a hot, dry start to June, keep an eye on sandy fields\u2026especially ones with skippy<br>stands. These will be at the highest risk for infestation.<\/li>\n\n\n\n<li>Under heavy pressure, no field is immune to LCB infestation. Irrigated fields are much less likely to reach<br>threshold once the vines lap the row middles, but we cannot irrigate enough to make LCB go away<br>before the vines lap. Our research last year clearly showed the benefit of an insecticide application in<br>June when thresholds are reached. There are two critical parts of the previous statement: 1. Benefit of<br>insecticide and 2. When thresholds are reached. Spraying preventatively for LCB is not a good idea.<br>Effective treatments are not cheap, and not every field will need to be sprayed even in an \u201coutbreak\u201d<br>year. Likewise, not treating when the threshold is reached is a bad idea. A UGA on-farm trial in 2022<br>showed a significant yield loss when the LCB threshold was reached in early June, and the pest was not<br>treated. The bottom line for LCB is simple: scout and treat when the threshold is reached.<\/li>\n\n\n\n<li>It has been a while since early season tobacco budworm (TBW) infestations have occurred over a large<br>area in Georgia, but we should be keeping an eye on our peanuts for this pest in June. A couple weeks of<br>\u201cnot paying attention\u201d when peanuts are 30-60 days old can result in a field of stems if TBW is present.<br>Peanut has an extraordinary ability to compensate for early season defoliation, but I don\u2019t like to see<br>them get stripped just as they are starting to peg.<\/li>\n\n\n\n<li>The name of the game for effective insect management in peanut is \u201cscout\u201d. If all goes well, June will be<br>nice and quiet, and we can all rest up and get ready for the circus that is probably coming to town in July<br>and August.<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>Entomology<\/p>\n","protected":false},"author":234,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1],"tags":[],"class_list":["post-1151","post","type-post","status-publish","format-standard","hentry","category-uncategorized"],"_links":{"self":[{"href":"https:\/\/site.extension.uga.edu\/benhillcoag\/wp-json\/wp\/v2\/posts\/1151","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/site.extension.uga.edu\/benhillcoag\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/site.extension.uga.edu\/benhillcoag\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/site.extension.uga.edu\/benhillcoag\/wp-json\/wp\/v2\/users\/234"}],"replies":[{"embeddable":true,"href":"https:\/\/site.extension.uga.edu\/benhillcoag\/wp-json\/wp\/v2\/comments?post=1151"}],"version-history":[{"count":1,"href":"https:\/\/site.extension.uga.edu\/benhillcoag\/wp-json\/wp\/v2\/posts\/1151\/revisions"}],"predecessor-version":[{"id":1152,"href":"https:\/\/site.extension.uga.edu\/benhillcoag\/wp-json\/wp\/v2\/posts\/1151\/revisions\/1152"}],"wp:attachment":[{"href":"https:\/\/site.extension.uga.edu\/benhillcoag\/wp-json\/wp\/v2\/media?parent=1151"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/site.extension.uga.edu\/benhillcoag\/wp-json\/wp\/v2\/categories?post=1151"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/site.extension.uga.edu\/benhillcoag\/wp-json\/wp\/v2\/tags?post=1151"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
